An HD version of Digital Betacam asing an 8-bit DCT compressed 3:1:1 recording, in 1080i-compatible downsampled resolution of 1440◊1080. The HDCAM codec uses non-square pixels and as such the recorded 1440◊1080 content is upsampled to 1920◊1080 on playback. The recorded video bitrate is 144 Mbit/s compared to DVCPRO HD at 100 Mbit/s. It has 4 uncompressed digital audio channels at 48kHz.
HDCAM SR is used commonly for HDTV television production. It uses a higher particle density tape and is capable of recording in 10 bits 4:2:2 or 4:4:4 RGB with a video bitrate of 440 Mbit/s, and a total data rate of approx. 600 Mbit/s. The increased bitrate (over HDCAM) allows HDCAM SR to capture much more of the full bandwidth of the HDSDI signal (1920◊1080). HDCAM SR uses the new MPEG-4 Part 2 Studio Profile for compression, and expands the number of audio channels up to 12 at 48 kHz/24 bit.
