Amlogic S905X4 Android TV & RDK developer kit ships with ATSC, DVB, or ISDB tuners

Amlogic S905X4 developer kit

SEI Robotics has launched an Amlogic S905X4 developer kit for Android TV & RDK development under their DroidLogic brand. The devkit looks like a standard TV box, and the company also provides a choice of tuners with DVB-S2, DVB-T2/C, DVB-S2+DVB-T2/C Combo, ISTB-T, or ATSC-T. We were expecting Amlogic S905X4 TV boxes with products like Ugoos X4 or Mecool KM6 by the end of last month, but due to supply issues manufacturing has been delayed. So SEI Robotics could be a good device to get started with your own project as soon as possible, for example, to work on AV1 hardware decoding implementation. DroidLogic Amlogic S905X4 developer kit specifications: SoC – Amlogic S905X4 quad-core Cortex-A55 processor with Arm Mali-G31MP2 GPU (Amlogic S905X3 as option) System Memory – 2GB DDR4 Storage – 8GB eMMC flash Video Output – HDMI 2.1 up to 4Kp60 with CEC, HDR, and HDCP 2.2 support; CVBS (composite […]

V-Bridge Muses DTV Modulator and Video Encoder Review – Part 2: Muses-β Turnkey Solution Demo

V-Bridge Muses-α and Muses-β boards can be used to respectively broadcast video to DTV standard from your PC, and as a turnkey solution taking any HDMI, CVBS, or USB inputs. The VATek SoC used in those  board support various DTV standards including DVB-T, DVB-C, ATSC/QAM, DTMB, ISDB-T/TB up to full HD resolution. I’ve received an early prototype for each, and I’ve already taken pictures and show how to assemble both Muses-α and Muses-β kits in the first part of the review. Today, I’ll show a demo with Muses-β turnkey solution taking HDMI input from an Android TV box (R-Box Pro), encoding and modulating the video to DVB-T, before broadcast it to an Android STB with a DVB-T/T2 tuner (U4 Quad Hybrid). This tool could be useful to test STB featuring ATSC or ISDB-T too, as those two standards are not supported in my country, and I could instead generate signals […]

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 […]
