  1. Answer: The Scale Video Codec (SVC) contains subset bitstreams that build upon each other to enhance resolution, frame rate and quality.

That said, I have a question out of curiosity.

RTSP streaming is not supported.Why is my stream’s overall bit rate higher than the sum of the audio and video bitrates?MPEG-2 transport streams can include substantial overhead. H.264 video access units must use Access Unit Delimiter NALs, and must be in unique PES packets.The segmenter also has a number of user-configurable settings. I'm asking because to save space on my Harddrive when I have a clip I want to use I encode it with H.264. Q) We have all heard about problems of streaming video online for a variety of heterogeneous devices, displays,networks, speeds, qualities, frame rates, manufacturers,etc!

In general, VC-1 will have better results for Windows and Macintosh playback, particularly when CPU performance is a bigger limitation than bandwidth. Why would you select one over other? Question: Should I deinterlace 1080i and downscale to 720p with an external hardware scaler, or should I put 1080i straight into the Expression Encoder for a 432 x 768 output size?
