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 […]
