Post production resolutions in storage vs display given the pixel aspect ratio. Digital Betacam is 720x486 in a 10-bit YUV @ 4:2:2 running a 2.34:1 DCT compression to yield a 90Mbit/sec data rate plus 4 channels of 20-bit 48Khz/sample uncompressed audio and a 5th linear audio cue track according to the front page of my DVW-A500 service manual. Active lines vs total lines which include the vertical blanking bar are often interchanged.
