Hi: What are the specs of uncompressed linear PCM video? The specs of uncompressed linear PCM audio are bit-rate, sample-rate, bit-resolution, and number of channels [1 if mono, 2 if stereo] In LPCM audio, Bit-rate = sample-rate X bit-resolution X # of channels In CD-audio, sample-rate is 44.1 kHz, bit-resolution is 16-bit, and with 2 channels [stereo] For CD, Bit-rate = 44,100 X 16 X 2 = 1,411,200 bits per seconds Thanks a bunch, Radium
Linear PCM video; specs?

The D1 digital tape format was an 8-bit serial protocol version at 216 Mbit/s. Rec. 709 is the equivalent format standard for HD. IMHO. YMMV.
