MPEG-2 Video I/O Modules
MPEG-2 is a common compression standard used for digital video broadcast in NTSC and PAL video formats. MPEG-2 addresses many of the problems inherent in previous video compression schemes (JPEG, M-JPEG, MPEG-1, and Wavelet) such as resolution, scalability and the handling of interlaced video signals.
The ADV264AV and DAV264AV modules combine MPEG-2 video and 16-bit audio on the same module with BNC connectors standard.
