HDMI typically sends uncompressed streams of audio and video. Basic math would be:
frame = 1920x1080x3 (Full-HD RGB)
videoBytesPrSecond = frame * 60 (assuming full progressive video)
audioBytesPrSecond = 3 * 96000*6 (24-bit, 96kHz, 6 channels)
totalBytesPrSecond = videoBytesPrSecond + audioBytesPrSecond
totalBitsPrSecond = 8 * totalBytesPrSecond ~= 3gbps
And that's just the payload, no transmission headers, no protocols, no signal-synchronization.
You do need a pretty cool computer to process and do crypto on that realtime. I say dedicated silicon/FPGA would be the way here.
- jimbobimbo 16y agoBut as long as ripping concerned - does it really need to be realtime?
- aquark 16y agoMaybe not, but that is still 384MB\s sustained write speed to your disk which is 22GB\minute so you'd need a 2TB disk for the average movie. Maybe in a couple of years when 2TB SSDs are cheaply available...
