Specs, Unboxing and Teardown of KI Plus Android TV Box with DVB-T2/S2 Combo Tuner

Orange Pi Development Boards

If you’ve been following this blog, you must now that I reviewed K1 Plus Android TV box based on Amlogic S905 processor a little while ago. Videostrong has sent me yet another K1 Plus device, except this time it is an Android receiver with a tuner card supporting both satellite (DVB-S/S2) and terrestrial (DVB-T/T2) reception. Today, I’ll list the specs, take a few pictures of the device, before checking out the tuner board.

K1 Plus Android DTV receiver specifications

The specifications are exactly the same as the TV box, except for the added tuner:

  • 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 NAND flash (4 to 32GB optional) + 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 – Combo DVB-T/T2 and DVB-S/S2 with two connectors
  • Connectivity – Fast Ethernet (Gigabit optional), 802.11 b/g/n Wi-Fi, optional Bluetooth 4.0
  • USB – 4x USB 2.0 host ports
  • Misc
    • Power button and LED, IR receiver
    • Optional DRM: Playready, Verimatrix, Widewine (Probably not available right now)
  • Power Supply –  DC 12V/1A
  • Dimensions – 130 x 120 x 32 mm

The device is still running Android 5.1.

K1 Plus DVB-S2/T2 Combo Picture

The package looks exactly the same as the media player model with KI Plus Quad-core Androdi DVB marking.

K1_Plus_DVB_Packageand the included accessories are exactly the same too with a 12V/1A, an HDMI cable, a remote control, and a user’s manual.Android_Digital_TV_Receiver_AccessoriesThe device itself also looks the same with 4 USB ports on the side…

KI_Plus_TV_Box..until we look at the rear panel where DVB-T2 and DVB-S2 antenna connectors have been added to a place where there was simply a marking with “Android TV Box” on the standard model.

K1 Plus DVB Teardown

I’ve already torn down K1 Plus without tuner, and the way to open it, and the mainboard are exactly the same, even the components, and only the tuner board has been added.

K1_Plus_Board_with_Tuner

So I’ve loosened the 3 connectors holding the mainboard and tuner to the casing, and removed the shield to have a closer look at the tuner board itself.

The board is called S2&T2_R848_Rev1.0 and includes Availink AVL6862TA DVB-C/T/T2 + DVB-S/S2 demodulator and Rafael Micro R848 tuner. The hardware configuration is very similar to TBS5520 multi-standard USB tuner with R848 tuner and AVL6882 demodulator with support for DVB-T2/C/S2/ISDB-T/J.83B standards.

Videostrong has listed the product on on their Alibaba website, and if you are a reseller or distributor you may consider contacting the company there to purchase in quantities.. I could not find it for sale yet on any online shops, and the name does not really make it easy to find either… [Update 24/02/2016: GearBest now has the device for $76.35]

Not good, S905 current revision have bug for 4k dvb streams

Question about the DVB-T2/S2 tuner. I assume from the description it is a multi-standard single tuner, so you can tune EITHER DVB-T/T2/C OR DVB-S/S2 at any given time, but not channels on both systems simultaneously.

If that is the case, when you test the box, can you see if it is possible to have tuning line-ups for both DVB-T2 and S2 at the same time, with connections to an LNB and an antenna/aerial at the same time, allowing you to surf between DVB-T2 and S2 transmissions, rather than having to decide on a single DVB-T2 OR DVB-S2 configuration when you tune initially?

It would be great to have the ability to integrate DVB-T2 and DVB-S2 channels into a single list.

it’s not a big deal, since we will use it with openelec

But still you have issue as problem is in HW decoding capabilities so they made new revision of soc to handle it. amcodec is as well used in OE

@kusta
I thought that the DVB decoding issue was simply software, the new S905M supposed to fix the VP9 decoding only, but if the problem is really HW, I don’t see any appeal for such a device at all

nevertheless, the DVB S2 stream from ASTRA on the CNX test was on “.ts” format very troublesome with the majority of video players even VLC et Daumpot on windows because it contains incorrected errors, those files must be corrected with TS DOCTOR before playing them, or choosing the “.ps” recording format instead

@natsu
kusta is talking about hw bug that exists S905 SoCs. There will be (or already is?) new HW revision of S905 SoC which has nothing to do with S905M.

And S905M is not fixing VP9 but adding HW VP9 decoder (it doesn’t exist in current S905).

Sad that there are no native PVR backends like Tvheadend or VDR for Android OS yet so that we can run Kodi / XBMC on the same Android device under Android OS and access the TV tuner from inside Kodi yet still run Android to have Netflix and other apps on it too.

I am not 100% sure but I think there is. I have seen it in F-Droid and I believe Wetek Play makes use of it on Android but I don’t own Wetek Play/Wetek Openelec box to confirm. I can confirm that i see it on F-Droid for all my android devices though but have never tried to install as I don’t have tuner for any android device.

nvm it looks like it is for watching and guide and not tvheadend so I am curious now how Wetek Play does live tv or does it?

@Harley
they are some binaries from TAki ON Freaktab, TVhend end worked fine for me on android but the problem, drivers are build with the kernel so TVheadend didn’t dectect the tuner at all

I will wait for wetek s9xx device with tuner support as play is dual core but still supported device on their forums

@cnx
please to try it with TVHEADEND, in fact it worked fine for me on ubuntu with linux deploy https://play.google.com/store/apps/details?id=ru.meefik.linuxdeploy&hl=fr but I didn’t have a DVB tuner back then, I don’t know if it will detect it or not, anyway it will be very interesting if it work, running the backend on linux deploy and keeping our android apps on the same time on the same device

@natsu & @Harley

Guys forget about VDR or Tvheadend.
Just have a try with Cesbo Astra backend.

@all others
Tuner SDK is Foss … anyone interested into development poke me to provide it

natsu
Guest
natsu

@ovi
cesbo is good but I never tried, besides is not free like tvheadend neither opensource I think, it’s a good idea to give it a try and see what compatibility it has with kodi

ovi
Guest

Cesbo have a free version … the only problem is that is scripted i mean you need manually to fill in dvb adapters and freq of sat/cable/T2 … you work a little bit more but once set is amazingly stable and can use any kind of frontend addon from Kodi.

Cesbo its really a solution to take in consideration as replacement for VDR and also for tvheadend.

@ovi
very nice, I see, if there is an armhf binary it will be nice to try it, normally it could work on android, just hopping that it will detect the DVB tuner

I just tried it, the raspberry pi binary worked fine on my phone 🙂

@ovi What do you mean, that backend has no Kodi support!

Don’t care about it if it doesn’t have a PVR client in Kodi.

@Harley
cesbo uses a standard HTTP protocole for streaming with m3u8 for vlc, just copy paste links in a standard .strm files or use an IPTV addon, that should do it

As I see it ATM, there is two possibilities for LiveTV STBs at the moment. Those companies, who come from the DVB market and center all their products around this. That gives you OpenEmbedded(Linux)/Enigma2 powered devices with up to 4 concurrent DVB (S/T/C) tuners, DiSEqC, Unicable, SAT>IP and so on. These start at €60 (single-tuner) and can go up to >€300 (full featured, up to 4 tuners). I have bought one for €180 (dual SAT), added an internal 500GB laptop drive
(ca. €40) and an additional DVB-T/C card (€30).

And then there is SBC integrators, who install Android or OpenELEC and add a DVB-Tuner.

I prefer option 1.

@ovi
I confirm, I’m using cesbo for 1 week now to stream files from my phone to PC, very stable, but if it didn’t detect the tv adapter within the kernel, it won’t be much of use

Box have root access by default,but i can not find any screen REC app which works.I need it to make video review.
For now i am not satisfied how it works,maybe i have bad device but only part which works fine is T2 part.Android and S2 have many problems or bugs.

natsu

@xxx
REC. is one among the best to use https://play.google.com/store/apps/details?id=com.spectrl.rec&hl=fr
the DVB S2 part is always troublesome due to very bad drivers and native app
if it works with CESBO or TVHEADEND it will be wayyy much better
looking forward to your video review

xxx
Guest

Hi
I have tested thet REC app,but all REC apps, gives me the same green video files.I think thet firmware have some bugs or my device is bad one,because of thet, i must to wait for CNX review to check what it is.

Very interesting box. It has everything i want – if it works flawless with openelec.
I want a box with DVB-T2 and H.265 – the upcoming standard in germany.
But the power options should work too, so it doesn’t draw too much power.
Looking foward to your review!

all sw part of DVB S2 receivers are average at best, chinese manufacturers should include TVheadend support by default like U4 do, that way we can use any app we like for playback
