The H.264 bitstream includes the Sequence Parameter Set (SPS) and the Picture Parameter Set (PPS). Both entities contain information that an H.264 decoder needs to decode the video data, for example, the resolution and frame rate.

My partner Mike Perkins and I traveled this week to Las Vegas to take in NAB, one of the big trade shows for the broadcast video market. We try to travel together once or twice a year because, in addition to whatever immediate objective we have in taking the trip, we’ve found that traveling together... View Article
