MUSES-α & MUSES-β DVB-T/C, ISDB-T, DTMB & ATSC Modulator Boards Review – Part 1: The Hardware

V-Bridge Muses digital TV modulator boards launched on Kickstarter earlier this month, with the cheaper $200 MUSES-α board modulating video from a PC, and $600 MUSES-β turnkey solution capable of broadcasting HDMI or AV + stereo input to various digital TV standards including DVB-T/C, ATSC/QAM, DTMB, and ISDB-T/TB without the help of a computer. The company sent me the two hardware kits for evaluation and review on CNX Software, and today I’ll start by showing off the hardware I received. I got 3 packages and a F-female to F-female cable, which means you can connect the board directly to your TV tuner without having to rely on actual RF signals, and potential legal issues that goes with it. The first package I open if for the PC modulator kit that include MUSES-α board, an “RF” board, as a USB cable to connect to your computer. MUSES-α board features Vatek A1 […]

V-Bridge Muses Digital TV Modulator Boards Let You Broadcast Your Own TV Channel for $199 and Up (Crowdfunding)

I wrote about VATek VMB8202D Enmoder SoC handling both DVB, ATSC, DTMB and ISDB modulation and H.264 hardware encoding earlier this summer, and at the time, the company also planned to launch a crowdfunding campaign for two open source hardware DTV modulation boards in a couple of weeks. Weeks turned into months, but finally V-Bridge Muses boards and video input & RF daughterboards have now launched on Kickstarter where you can get your own live video broadcasting board for $199 and up. MUSES-α board MUSES-α board is the cheapest of the two boards, and features a header for the RF daughter board, and a USB port to connect to a computer. MUSES-α board specifications: SoC – VATek A1 32-bit RISC modulator chip Storage – SPI flash (unclear whether it can be accessed/modified by user) Modulation – DVB-T/C, ATSC/QAM, DTMB; RF header Video Encoding – N/A (handled by PC via USB […]

4K VP9, H.265 and H.264 Video Playback in Amlogic S912 M12N TV Box

I’ve received my first Amlogic S912 TV box with MXQ Plus M12N TV box this week-end, and I’ve decided to start testing by showing the media capabilities of the platform that is supposed to support 4K VP9 up to 60Hz, 4K 10-bit H.265 up to 60Hz and 4K H.264 up to 30 Hz. I connected the device to Onkyo TX-NR636 A/V recevier itself connected to  LG 42UB820T 4K UHD TV, set video output to 2160p @ 60Hz, and played several 4K video samples from a USB hard drive using the pre-installed version of Kodi 16.1: 4K Hawaii Sunset _ GoPro Hero 4 Black [email protected] (Downloaded from YouTube) – OK Beauty_3840x2160_120fps_420_8bit_HEVC_MP4.mp4 (H.265 @ 30 fps – No audio) – OK big_buck_bunny_4k_H264_30fps.mp4 (H.264 @ 30 fps – MPEG1/2 and AC3 audio) – OK big_buck_bunny_4k_H264_60fps.mp4 (H.264 @ 60 fps – MPEG1/2 and AC3 audio) – Video a bit choppy, large audio delay. Expected […]

Multiple Videos Encoding and Decoding in Android on Firefly-RK3288 Development Board

Some applications like digital signage and video surveillance may require simultaneous video playback, and encoding to send over the network. ARM platforms may not be powerful enough to achieve those tasks with the processor only, but luckily many ARM SoCs include powerful video processing unit (VPU) capable of doing both hardware video encoding and decoding, leaving the CPU cores mostly free for other tasks. Firefly team has demoed such capabilities on their Firefly-RK3288 development board by displaying 7 videos on a single screen, including two previews from two USB cameras attached to the board, which are then encoded and decoded on the fly and displayed on the screen. The last three videos are played from 3 different files. So that means that 5 video decode and 2 video encode are running simultaneously.  The board can achieve 26 to 30fps with 720p videos, and around 13 to 15 fps with 1080p […]

EBox T8-4 Review – A 4K Android TV Box Bundle Geared Towards the UK Market

I’ve already taken some pictures of the device and board in part 1 of EBox T8-4 review, so today, I’m going to report my experience with the Android 5.1 firmware for this Amlogic S905 TV box, air mouse, and wireless gamepad, specifically targetted to users leaving in the United Kingdom, but since the hardware is based on Zoomtak T8V, it may also be informative to international users, although the firmware, mostly launcher and IPTV services, will be different. EBox T8-4 Setup Wizard & Configuration Since I’ve already inserted an internal SSD into the SATA bay of the device, I did not connect an external USB harddrive, and only connected HDMI and Ethernet cables,  plus the RF dongle for the included air mouse, a USB keyboard to easily take screenshots, and of course the power cord. The power button will be red at this stage. If you want to start the […]

Review of Vorke V1 mini PC Powered by Intel Celeron J3160 Processor

After checking out Vorke V1 mini PC hardware in the first part of the review, it’s now time to publish the review starting with system information, benchmarks, and user testing. The device competes with similarly priced devices based on Intel Atom x7 processor such as Voyo V3 and Beelink BT7, so I’ll also include some comparisons to those in the review. Setup and System Information I connected USB keyboard and mouse, an Ethernet cable, HDMI and VGA cables to check dual display support, as well as the power supply. I did not connect my USB 3.0 hard drive since, I’ve already fitted the mini PC with an internal 1TB hard drive. Pressing on the large power button on the top of the device will boot it, and after a few seconds, you’ll get to go through Windows 10 setup by first accepting the EULA. The next steps are Custom or […]

Improve YouTube Video Playback on Low Power Intel mini PCs by Disabling VP9 Support in Chrome or Firefox

I’ve been reviewing several Intel Bay Trail, Cherry Trail, and Braswell mini PCs in the last year or so, and I always end up recommending Microsoft Edge browser over Firefox or Chrome for people wanting to watch YouTube videos, as the last two browsers always drop many frames with the video stuttering regularly. However I noticed that while Edge is playing  MP4/AVC (H.264) video, the other two browser would normally stream WebM/VP9 videos, and it could be the cause of the problem as H.264 can be hardware accelerated, but VP9 not, and the low power processor might not quite powerful enough to handle 1080p VP9 video decoding smoothly. So I investigated the issues with Vorke V1 mini PC powered by an Intel Celeron J3160 processor (6W TDP) with the three browsers by first checking enabled codecs in YouTube HTML5 page. Microsoft Edge has both VP8 and VP9 disabled When I […]

FFmpeg 3.1 adds support for OpenMAX encoding on Raspberry Pi, VA-API H.264 & H.265 Encoding, and more

FFmpeg is an open source multimedia framework used by many open source, as well as closed source, projects to handle audio and video containers parsing, hardware or software video decoding / encoding, and more. I also used it a few months ago to test H.265 hardware encoding with an Nvidia GPU using the development branch, but the developers have now released FFmpeg 3.1 “Laplace”, so it’s possible to use a stable release to perform H.265 hardware encoding. Some of the most noticeable features of the new version include: Generic OpenMAX IL H.264 & MPEG4 encoders for Raspberry Pi VA-API accelerated H.264/HEVC/MJPEG encoding VAAPI-accelerated format conversion and scaling Native Android MediaCodec API H.264 decoding CUDA (CUVID) HEVC & H.264 decoders CUDA accelerated format conversion and scaling DXVA2 accelerated HEVC Main10 decoding on Windows Many new muxers/demuxers A variety of new filters The complete list of changes for FFmpeg 3.1 can be […]
