Giveaway Week – Muses-β DTV Modulator and Video Encoder

The next item for giveaway is rather specialized hardware, as V-Bridge Muses-β allows you to take raw video input via HDMI or video composite, encode it and module to your DTB standard (DVB-T, ATSC… ) and get the video through your TV tuner via a cable, or over-the-air if you add your own an amplifier and antenna. The system is controlled by an STM32 board with LCD display and button, and you can operate directly from the board, selecting various option. I used a TV box as input, and U4 Quad hybrid set-top box to get the video signal and output it to my TV when I reviewed the system with DVB-T / QPSK modulation. The system is limited to MPEG-2 up to 1080p30 encoding since it’s what the SoC supports. I’m giving away the complete “turn key solution” shown in the first photo to one lucky winner. To enter […]

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 […]

VATek VMB8202D Enmoder SoC Supports DVB, ATSC, DTMB and ISDB Modulation, H.264 & MPEG-2 Encoding up to 1080p30

Terrestrial digital TV transmitters normally cost over 1,000 dollars because there are usually implemented with expensive FPGA chips, but Taiwan based VATek has designed a low cost chips such as VMB8202D Enmoder (aka B2 Enmoder) capable of encoding 1080p60 video input to MPEG-2  (1080p30 max) or H.264 (SD resolution max), and transmitting the resulting video over DVB-C, DVB-T, ATSC, DTMB, or ISDB-T standards. VATek B2 Enmoder SoC specifications: CPU – 32-bit RISC @ 400MHz Memory – Built-in DDR Modulation Engine – VATek Multi-standard Modulator 1.0 ATSC / DTMB / DVB-T / DVB-C Media Encoder – VATek Ultral Low Latency HD Encoder supporting 1080p30 or SD MPEG-2 and SD H.264 encoding Audio Formats – MPEG-1 Layer 2, AAC Raw Video Inputs – 1x ITU-R BT.1120 or 2x ITU-R BT.656 up to 74.25MHz pixel clock Raw Audio Inputs – I2S up to 48kHz sample rate Stream Input Interface – Ethernet,  Transport Serial […]
