The board is sold with Android 5.1.1, but it will be the main development platform of Linaro Digital Home Group which aims “to continue creating optimized, high-performance secure media solutions for ARM on both Linux- and Android-based platforms. Licensees of the RDK (Linux) will be able to create Open Embedded/Yocto RDK builds for Poplar. The Poplar board will also serve as a common development platform for Android TV (AOSP) as well as for TVOS-based STB solutions used in China.”

In the meantime, you may find some information on Tocoding Poplar page, or access directly the hardware user manual. Eventually, 96Boards Poplar page will be a good place to look.

Xtreamer mxV Plus DVB-T2 and mvX Pro DVB-T2/DVB-S2 Combo TV Boxes Support Android and OpenELEC

August 25th, 2016 15 comments

Xtreamer mxV is a family of TV boxes powered by Amlogic S905 processor, and supporting Android 5.1 and OpenELEC firmware provided by the company [Update: It looks like they simply used Vitmos/ image]. There are three models: mxV without tuner, mxV Plus with a DVB-T2 tuner, and mvX Pro with a DVB-T2/DVB-S2 combo tuners.


The three devices share the same specifications:

  • SoC –  Amlogic S905 quad core ARM Cortex-A53 @ up to 2.0GHz with  penta-core Mali-450MP GPU @ 750 MHz
  • System Memory – 1GB DDR3
  • Storage – 8GB eMMC flash + micro SD card slot
  • Video Output – HDMI 2.0 up to 4K @ 60Hz with HDCP 2.2 support, and 3.5mm AV jack
  • Audio – HDMI, AV (stereo), optical S/PDIF
  • Video Codecs – 10-bit H.265 up to 4K60, MPEG/VC-1/AVS+/H.265 up to 4K30
  • Tuner
    • mxV – None
    • mxV Plus – DVB-T2 tuner with two connectors
    • mxV Pro – Combo DVB-T/T2 and DVB-S/S2 with two connectors
  • Connectivity – Fast Ethernet, 802.11 b/g/n Wi-Fi
  • USB – 4x USB 2.0 host ports
  • Misc – Power button and LED, IR receiver
  • Power Supply –  DC 12V/1A
  • Dimensions – mxV: 130 x 110 x 32 mm; mxV Plus / Pro: 130 x 120 x 32 mm

The device ships with IR remote control, a quick instruction guide, an HDMI cable, and a 12V/1A AC/DC power adapter. If the design and specs looks similar, it’s because mxV is based on K1 Plus, and mxV Pro on K1 Plus T2/S2. According to a post on Freaktab, mxV firmware either Android 5.1. called “Xtreamer Android TV OS” and supporting OTA firmware updates, or OpenELEC OS released by the company also work on K1 Plus devices. K1 Plus DVB TV boxes have supported OpenELEC (Vitmos build) for several months already, but the Xtreamer version appears to be officially supported by the company.

mxV_EPG_GuideXtreamer boxes are also reasonably priced with mxV selling for 39 Euros, mxV Plus for 49 Euros, and mxV Pro for 59 Euros. At first prices in Euros made me think it was sold from Europe, avoiding custom issues (e.g. “my” WeTek Play 2 has been stuck in customs for 3 weeks with basically no hope of getting it out) and extra duties, but it’s actually shipped from Hong Kong. You can find more information and/or purchase the devices on Xtreamer mxV product pages.

Thanks to Slowstream for the tip.

S204 Android Set-top box with DVB-T2/C & DVB-S2 Tuners is Powered by Allwinner H3 Processor

June 17th, 2016 12 comments

So far, I had only seen Android TV box with digital TV tuner using Amlogic or HiSilicon solutions, but S204 Android set-top box differs, as it is powered by Allwinner H3 quad core Cortex A7 processor, and includes DVB-T2/C (Terrestrial and cable TV) and  DVB-S2 (satellite TV) tuners. AFAIK, Allwinner H3 does not include any TS interfaces, so they must have used USB tuner chip(s) [Update: Allwinner H3 does have a Transport Stream interface as per the datasheet, but it’s not really advertised by Allwinner]

S204_TV_BoxS204 TV box specifications:

  • SoC – Allwinner H3 quad core Cortex A7 @ 1.2/1.3 GHz with Mali-400MP2 GPU
  • System Memory – 1GB DDR3
  • Storage – 8GB flash + micro SD slot
  • Video Output – HDMI 1.4 up to 4K @ 30 Hz + AV (composite)
  • Audio Output – HDMI, AV (stereo audio), and optical S/PDIF
  • Tuners
    • Support HD DVB-S2, DVB-T2 and DVB-C;
    • Support for BISS,CCCAM, NEWCAM, GSCAM, and MGCAM
    • LNB in with satellite dish antenna, RF input for indoor / outdoor terrestrial antenna or cable
  • Connectivity – 10/100M Ethernet, 802.11 b/g/n WiFi
  • USB – 2x USB host ports, including one OTG capable port
  • Misc – Power button, front panel LCD display
  • Power Supply – 12V/1.5A
  • Dimensions – 140 x 120 x 25mm
  • Weight – 326 grams

The device runs Android 4.4.2 and ships with a remote control, a power adaprer, HDMI and AV cables, and a user’s manual. If the screenshots are to be believed, the interface appears to be the same eOn center launcher as used on U4 Quad Hybrid, which offers support for PVR, Time-shifting, EPG, a configuration web interface, and more, and is actually pretty good.

Allwinner_H3_Tuner_TV_BoxS204 is sold for $79.99 on GeekBuying, and considering it’s unclear whether it will get the same level of support as U4 Quad Hybrid, does not feel like such a good deal as K1 Plus T2 S2 is now sold for $60, and supports 4K DVB-S2 @ 60 fps thanks to an Amlogic S905 processor. The manufacturer could be a company called L&Y electric industries Co based on listings for a DVB-T2/C only model on Global Sources and ECPlaza.


Stream Live TV to Your Computer or Smartphone with U4 Quad Hybrid Android TV Box, Kodi and TVheadend

March 25th, 2016 22 comments

TVheadend is a streaming server and recorder for Linux, FreeBSD and Android supporting DVB-S, DVB-S2, DVB-C, DVB-T, ATSC, ISDB-T, IPTV, SAT>IP and HDHomeRun as input sources, and while in theory it should be possible to configure any recent Android TV set-top box with digital TV tuners, configuration is complex, and there’s no guarantee the tuner will be recognized. However, the manufacturer of U4 Quad Hybrid has already configured their box to support HTSP clients, so I’ve installed the latest firmware, and given it a try with my Android smartphone running Kodi 15.2 with TVheadend HTSP client, and I could successfully stream live TV (DVB-T2 free-to-air channels) to my smartphone.

Once you’ve scanned the channels using DVB-T2 and/or DVB-S2, there’s no other configuration in U4 Quad Hybrid TV box, but you’ll still need to find out your IP address by going to Setup->Network, and WiFi, Ethernet or 3G depending on your chosen Internet connectivity option. My device is connected to Ethernet, and my IP is

I’m using a smartphone, but you could as well go with any device or computer that support Kodi. Currently the firmware in U4 Quad Hybrid is not compatible with Kodi 16.0, so you’ll need an earlier version, and I installed Kodi 15.2 on my phone. You can download Kodi 15.2 for Windows or Android here.

Once Kodi is installed, you can start it, and go to Settings->Add-ons->My add-ons->PVR clients, and scroll down to select TVheadend HTSP client.

Click on Configure to enter U4 Quad Hybrid IP address in “Tvheadend hostname or IP address” field, and click OK.
Kodi_HSTP_Client_ConfigurationBy default,the add-on is disabled, so you make sure you select “Enable” too. Now go back, and enter Settings->TV to tick Enabled.Kodi_TV_SettingsConfiguration is now complete, and when you go back to Kodi home screen, you could see a new TV menu with five sub-section: Channels, Guide, Recordings, Timer, and Search.


I’ve just tapped on TV, and got the list of apps from U4 Quad Hybrid set-top box on my smartphone.  The channel information (in Thai language) was not displayed properly for some reasons.

Kodi_Live_TV_channels Now select any channels from the left, and will it start playing in the preview windows, and tap the preview and it will switch to full screen.

Once the video is playing you can also tap the screen to have access to options, change channels, change audio tracks and so on.

You can watch the video below to see all configuration steps, and a demo starting at 3:15.

If you are interested in U4 Quad Hybrid you can purchased it on Aliexpress for $119.99 (DHL) or $106.69 (China Post). I intend to post a complete review next week.

Telechips TCC898x (Alligator) 64-bit ARM SoC is Designed for High-end 4K Set-Top Boxes

March 18th, 2016 2 comments

Telechips processors were often found in consumer devices such as Android tablets, mini PCs and TV Sticks a few years ago, but it’s been a while since I have seen a devices based on Telechips. So after seeing an automotive SoC from the company, I decided to visit the company website to check if they were still designing processors for the consumer market, and found TCC898x quad core Cortex A53 processor for “Smart Stick, IP-Client and STB with 4K 60fps decoding” with some interesting features.

Telechips_TCC8980Telechips TCC898x SoC specifications:

  • CPU- Quad core Cortex A53 processor with NEON, TrustZone, 32KB/32KB L1 cache and 512KB L2 cache
  • MCU – Cortex-M4 micro-controller
  • GPU
    • 2D – Vivante GC420 composition processing core for 4K user interfaces
    • 3D – ARM Mali-400MP2
  • VPU – Multi-format VPU and 4K VPU with HEVC and VP9 support
  • Memory I/F – DDR3/4
  • Storage I/F – NAND controller (60-bit ECC), SD/eMMC controller
  • Peripherals
    • Video Output – Display Controller, LVDS transmitter, HDMI 2.0 with HDCP 2.x, video composite
    • Video Input – Yes, but no details.
    • Audio – S/PDIF Tx and Rx, 9.1 channels I2S , stereo I2S
    • USB – USB 2.0 host, USB 2.0 OTG, USB 3.0
    • Gigabit Ethernet MAC
    • TS and TS demux (normally used to interface tuners)
    • PCIe interface
    • I2C, UART, GPSB (General Purpose Serial Bus), SDIO
    • Timer/RTC, DMA, IR receiver

The overall concept is pretty similar to their Telechips TCC893x Cortex A9 + Cortex-M3 processor, except most items have been upgraded, except notably the 3D GPU which remains a Mali-400MP2.

Telechips TCC898x supports Linux (with HTML5 interface) and Android operating systems, and contrary to most other Android TV boxes and set-top boxes, devices based on the new processor will support 4K user interfaces too thanks to Vivante GC420 2D GPU.  The chip also support hardware cyphers and conditional access (CAS) for “full compliance with 4K contents security guideline for variable STB applications”. I could not find much more information, and Googling for TCC8980 processor (and others up to TCC8989) did not return anything interesting so far. The last update to Telechips open source page shows the company released Linux 3.4.45 source code in February 2015.

MXQ 4K Rockchip RK3229 Android TV Box Unboxing and Teardown

March 7th, 2016 45 comments

MXQ 4K TV box list of features is rather impressive, as the 4K media player packs support for high bitrate (200 Mbps+) 10-bit H.265 and H.264, as well as VP9 at 4K resolution, 4 USB ports, Ethernet, and HDMI 2.0 for just $30. That price includes shipping. We just don’t know how it performs, but we’ll soon find out as GeekBuying sent me a sample for review. I’ll start by checking out the hardware, before testing it over a few days, and write a complete review.

MXQ 4K Unboxing

The retail package shows MXQ-4K  “OTT TV Box” and some of the key selling points like Kodi support, 4K, HEVC/H.265, and son on. You’ll also find the Android 4.4 Kitkat logo since strangely Rockchip did not provide an Android 5.x SDK for their low cost processor.

MXQ-4K_OTT_TV_BOXThe device ships with an IR remote control, a 5V/2A power supply, an HDMI cable, and a user’s manual in English.

The enclosure is a standard looking black rectangular box with an SD card slot, and three USB port on one side, as well as several ports on the rear with one USB 4 port, two 3.5mm jacks for coaxial S/PDIF and AV (composite + stereo audio), the HDMI 2.0 port, a Fast Ethernet port, and the power jack.

MXQ 4K Teardown

It will be quite interesting to open it to better understand how they could keep the price that low. I had to peel off four sticky rubber pads, and loosen four screws to take the device apart. Pretty straightforward.

MXQ-4K_Bottom_CaseThere’s also a sticker with a MAC address starting with 72:F1:6D on the case, which looks up to … nothing. So either the company only recently registered, or they just made up some MAC addresses by themselves to save on registration costs…MXQ_4K_Board_Bottom

This is what the board looks after opening the case, and there’s a single chip: SanDisk X505260971 NAND flash with 8GB capacity.

Taking out the board completely explains why the device is quite cheap, as many features are integrated into Rockchip RK3229 processor, including the Ethernet PHY and audio codec, and the four USB ports has not using a USB hub chip either.

There’s only RK3229 with a heatsink, two NANYA NT5CB256M16CP-D1 RAM chips, Pulse H1102NL magnetics for 10/100M Ethernet, and Espressif ESP8089 Wi-Fi chip, probably one of the cheapest, if not the cheapest WiFi IC on the market for this type of device.
MXQ-4K_ESP8089_WiFiYou’ll also have noticed two push buttons right behind the 3.5mm jack. The user’s manual explain the one behind the AV port is for firmware upgrade, and but I’m not sure what the one behind the S/PDIF port is for entering bootloader mode. There is also an unpopulated 3-pin header on the bottom right which should be for the serial console, and the board is named T066-V1.

As mentioned in the introduction, GeekBuying kindly provided the sample for review, and you can purchase the device for $29.99 shipped from them if you are interested. Other shopping options include GearBest, Banggood, and Aliexpress.

Review of K1 Plus Android TV Box with Combo DVB-S2/DVB-T2 Tuner

February 28th, 2016 209 comments

VideoStrong has launched K1 Plus TV box powered by Amlogic S905 processor last year, and I had the chance to review their model last November. But here I am reviewing K1 Plus again. Why? That’s because the company’s has several K1 Plus models: the “standard” version that’s just like any Android TV boxes, and the DVB version with DVB-S2, DVB-T2/C, or DVB-T2/C + DVB-S2 combo, and the latter is the one I’m reviewing today. K1 Plus DVB combo teardown revealed that the main board was exactly the same as K1 Plus “standard”, and that only a tuner card was added. So I’ll have a two part review with the first part checking if they fixed any of the bugs found on K1 Plus “Standard” with “November 2015” firmware in the new “January 27, 2016 DVB” firmware, and the second part will focus on testing DTV app with DVB-S2 and DVB-T2, PVR and time-shifting.

K1 Plus “Standard” vs K1 Plus DVB Firmware

The launcher used in DVB firmware is exactly the same as in the standard version.


I listed some pros and cons in my conclusion of K1 Plus “standard” review. Let’s check out the cons, and find out if they’ve been fixed or improved:

  • Pre-installed Kodi 15.2 version does not work well when 2160p video output is selected (1080p output looks better); automatic frame rate switching is not working either.
  • HDMI – Dolby Digital 7.1+, DTS HD and Atmos pass-through not working; CEC not working; Video output resolution set in settings is not always used at next power on.
  • Missing DTS and Dolby support for PCM output
  • No DRM installed, even Widewine Level 3 required for SD playback on relevant apps.
  • WiFi performance may be erratic (TBC), very good sometimes, and near stall speed at others.
  • 3D games such as Beach Buggy Racing and Riptide GP2 are not playing very smoothly, and performance may degrade with play time (and higher heat).
  • No option to show status and notification bars, no Download icon in app list.
  • Lacks Bluetooth support
  • USB hard drive partitions (NTFS / exFAT) reported as having 10MB free only, basically rendering the partitions read-only.

The pre-installed version of “Kodi” is still 15.2 with some add-ons, but the build date has changed from 2015-11-09 to 2015-12-07, so there may have been some improvements.


Click for Original Size

First I had to be careful to check output resolution is to 2160p @ 60 Hz, because the system will always revert to 1080p50 (as shown in the screenshot above), which remains a bug yet to be fixed. All videos were shown in Letterbox mode in K1 Plus “standard”, and i’s nice to see this have been fixed:

  • H.264 codec / MP4 container (Big Buck Bunny) – 1080p – OK
  • MPEG2 codec / MPG container –  1080p – OK
  • MPEG4 codec, AVI container 1080p – OK
  • VC1 codec (WMV) – 1080p – OK
  • Real Media (RMVB), 720p / 5Mbps – OK
  • WebM / VP8 – OK
  • H.265 codec / MPEG TS container (1080p) – OK
  • WebM / VP9 (no audio in video) – OK

4K video are also fairly well supported:

  • HD.Club-4K-Chimei-inn-60mbps.mp4 – OK
  • sintel-2010-4k.mkv – OK
  • Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265) –  OK
  • BT.2020.20140602.ts (Rec.2020 compliant video) – Stays in UI
  • big_buck_bunny_4k_H264_30fps.mp4 – OK
  • Fifa_WorldCup2014_Uruguay-Colombia_4K-x265.mp4 (4K, H.265, 60 fps) – OK
  • Samsung_UHD_Dubai_10-bit_HEVC_51.4Mbps.ts (10-bit HEVC / MPEG-4 AAC) – stays in UI
  • Astra-11479_V_22000-Canal+ UHD Demo 42.6 Mbps bitrate.ts (10-bit H.265 from DVB-S2 stream) – Stays in UI

Unfortunately none of the 10-bit H.265 videos are playing. But it’s still a big progress since Kodi was pretty unusable in the standard version.
Last time I tested HDMI audio pass-through with Video Player, and this time I did it with Kodi, and sadly it’s not really usable.

  • AC3 / Dolby Digital 5.1 – Audio OK (Dolby D 5.1), video not smooth
  • E-AC-3 / Dolby Digital+ 5.1 – OK (Dolby D 5.1) most of the time, but two small audio cuts occurred during playback
  • Dolby Digital+ 7.1 – PCM 2.0 only
  • TrueHD 5.1 – PCM 2.0 only
  • TrueHD 7.1 – PCM 2.0 only
  • Dolby Atmos 7.1 – PCM 2.0 only
  • DTS HD MA – DTS 5.1 only, and two short audio cuts during playback
  • DTS HD HR – DTS 5.1 only, and one short audio cut during playback

That’s especially announcing since WeTek fixed HD audio pass-through in Amlogic S8xx and S9xx and confirmed it to work in both WeTek Core, and WeTek Play 2S at the beginning of the month, and even released the source code. But maybe Kodi is not a priority for Videostrong, and/or Chinese New Year holidays may have made February a slow month in China..

Since the company is not using Amlogic S905-H processor there was no way DTS and Dolby downsampling to PCM (stereo) would work with other apps, and I could confirm that MX Player would not output any audio from playing such files over PCM output.

I played a 2-hour 1080p video over WiFi from a SAMBA share, and it worked just fine.

DRM_Info_K1_Plus_DVBAt least Widewinve DRM is now support (Level 3), and that a small step in the right direction. So overall video output and playback support have improved, but it’s not quite at the level of the competition.

Wifi was quite stable overall, but performance had it’s up and downs and the average throughput was lower than K1 Plus “standard”.

Throughput in Mbps

Throughput in MB/s

Bear in mind that WiFi performance can be extremely volatile, and when I tested K1 Plus DVB, the transfer time for a 278 MB file varied between 1m15s and 2m22s during my several attempts.

I also had some new issues with both Google Play and Amazon Underground. I could browse app and select them for installation with the former, but after a few minutes I realized that none of 16 apps I selected would install, as it was waiting for WiFi connection, and I was using Ethernet… So I switched to WiFi, and I could complete the installation. Amazon Underground failed to install for unknown reasons, but the patented bug fixing method called “Good Night SleepTM” resolved the issue, and the app could install the next morning.

Once I managed to get Amazon appstore running, I could install Riptide GP2 racing game, which I played for 15 minutes both to test 3D graphics performance, and stability. I basically had the same issue as with K1 Plus, with the games crashing if I adjusted the graphics settings higher, poor performance with “high resolution” (MAX-4) settings, and the game became less and less playable over time, with some micro freezes (around second) occurring from time to time. Temperatures measured with an IR thermometer on the top and bottom of the case were respectively 56 and 64C after around 15 minutes. I also went to CPU-Z to check aml_thermal after the game, and the reported temperature was 86C, which seems pretty high.

All other Amlogic S905 TV boxes I’ve tested before have the 10MB USB hard drive bug, meaning I can only read from my USB hard drive, or copy files smaller than 10MB, because the size is incorrectly detected. Since K1 Plus DVB has a PVR function it’s very important for it to work. Sadly it still has the same bug, so I’ll have to use a 64GB flash drive (properly detected) in order to record live TV or use timeshifting. I first discovered this bug in August 2015 on Mygica ATV1900AC, so 6 months later I would have expected it to be fixed, especially since I’m not the only one to have the issue.

Videostrong had two months (end of November until end of January) to fix the bug found in my first review, and I have to say I’m very disappointed with the progress done so far, with most critical bugs still there, and the only positives being a somewhat working Kodi (with several caveats) and DRM support. Oh yes, and there’s still no way to show the status and notification bars,  so you’d have to hack the system by changing systemui.apk and build.prop, as explained by Karl in his review of Eny EM95 TV box.

DTV app for DVB-T2 and DVB-S2 Free-to Air channels

The main selling points of K1 Plus DVB box is the combo tuner, and you’ll need to start DTV app to get access to live channels.

Android_DTV_appOnce you’ve connected your satellite dish for DVB-S2, and terrestrial antenna for DVB-T2, you’ll be ready to configure the syste,. Since there are a few steps involved I’ve already explained how to scan DVB-T2 and DVB-S2 channels on K1 Plus Amlogic receiver. My configuration is using a simple fixed satellite dish, but there are options to control a motorized satellite dish, and/or multiple satellite dishes via DiSEqC.

Once the system is configured, you’ll need to select whether you want to use DVB-S2 or DVB-T2 each time your start the app, but you can press the DTV button on the remote to quickly restart the app and change the tuner selection.

Live TV is working pretty well, and switching between channels does work quite fast for both DVB-S2 and DVB-T2, although for the first couple of seconds the video is not 100% smooth.

K1_Plus_DVB-T2_ChannelIf you are using languages with accents or complex languages there may be issues, as you can see is the case for Thai language in the overlay info window above. The Electronic Program Guide (EPG) can be accessed with the corresponding remote control key, and it is working, although sometimes it’s pretty slow to get the data, and with the same font rendering issues.

And once you are in the EPG, you can select a program and press OK to either schedule to box to Play or Record a program, with the icon R or P showing on the right side of the screen once you’ve done the selection.


You can consult the schedule list (Book List) by pressing the Blue button, and the system appears to handle programming conflicts too.K1_Plus_Timer_List


Scheduling works well, as long as you let the DTV app running in the foreground. If you use a web browser or play games in Android, the scheduled recording or play time will be start automatically. Same thing is you schedule a program on DVB-T2, and you are currently watching live TV with DVB-S2, it will not switch automatically. The device must be running all the time, since there’s only on or power off, if you plan to schedule recordings. Power consumption is relatively low at around 10 watts with storage, but it’s still annoying. So I don’t find the K1 Plus set-top box to be user-friendly from that point of view.

You can also record manually by pressing the PVR key on the remote control. Recording works pretty well, and videos can be found in DTVRecordFiles of your storage device both with .ts (the videos) and .amdur files. You can play the video directly from the DTV app by going to the Menu and selecting Record list, or from media players on your Android device, and the results is usually satisfying. However, I also copied some files to my computer, and I could play them with some artifacts at the beginning in VideoLAN (VLC), but not at all in Totem video player.

K1_Plus_Video_Recording_FormatThe video were recorded at 1080p at 25 fps using H.264 AVC codec, and they’ve properly recorded both audio tracks (AAC). Here’s a short sample.

Timeshifting can  be enabled with the Play/Pause key on the remote, and working reasonably well with possibly some artifacts when enabling the function, with a default recording time of 5 minutes, but the length is configurable in the PVR options.K1_Plus_PVR_Settings

There’s also a hidden “Smart Data Manager” menu which you can enabled by pressing the Menu key, going into Installation, and pressing 111111 in the remote.

K1_Plus_DVB_CCaamThis will give you access to “Smart Data” and “BISS” but it’s not something I have tried.

You can check the video review to have a better understanding of the digital TV capabilities and performance of K1 Plus DVB. bear in mind that I could only tried SD and HD channels, since I have not found 4K UHD channels, even test channels, in my location.


K1 Plus DVB Android set-top box is one of the few Android TV boxes on the market with a combo DVB-S2 & DVB-T2 tuner, and I’m glad Videostrong brought this type of product to market. However, I’m very disappointed by the progress made on the firmware front between my review of K1 Plus standard with a firmware released in November, as they’ve almost fixed none of the issues I reported at the time. Kodi has improved a little (10-bit H.265 is not working though), Widevine DRM Level 3 has been enabled, but 3D games (Riptide GP2) still crash when graphics settings are set to high, 3D graphics performance is quite poor compared to other Amlogic S905 devices, it overheats leading to CPU/GPU throttling, the system feels sluggish at times with apps loading slowly, I still can’t use my USB hard drive (10MB bug), the user’s interface does not provide access to status and notifications bar, and so on… So it feels like either Videostrong does not have the resources for development, they don’t really care (or really think the firmware is good enough), or they are incompetent…

However, the DVB part is not that bad, as least compared to some other Amlogic Android DVB boxes I’ve tested in the past such as HD18T or ATV586. Most features work reasonably well, and I could use both DVB-S2 and DVB-T2 parts, but there are still some bugs such as artifacts at the beginning of recording videos or Timeshifting, and (Asian) font rendering issues. The system integration is also inexistent, meaning that the TV box and DTV app must be running at all times for scheduling to work, there’s no background process handling this, and you can’t simply use other Android apps, and expect to get a pop-up when the recording/playback start time has been reached. You also have to chose between DVB-S2 or DVB-T2, as you can’t record a program on DVB-S2, while watching a program on DVB-T2 for example.  The idea behind having a combo tuner is great, and it works, but the implementation is not as user-friendly and good as one may have expected.

I’d still like to thank Videostrong for giving me the opportunity to review both their K1 Plus “standard” and K1 Plus DVB combo, and resellers and distributors can contact the company via their Alibaba page for further request and/or purchase in quantities. K1 Plus DVB-S2/T2 Android TV box is currently sold for around $76 on GearBest and GeekBuying.
