Compression needed for Video
transmission or recording• Should be compressed at Video transmission orrecording because;– Original video data is 1.5Gbit/s.

4Compression needed for Video
transmission or recording• MPEG-2 is the most common compression technology.
• AVC/H.264 compression efficiency is more than double thatof MPEG-2.

AVC/H.264 vs MPEG2Coding Performance Comparison• AVC/H.264 compression efficiency is more thandouble that of MPEG-2.
– But required processing power is 10-100 times that ofMPEG-2’s.
– Even with the latest Core 2 Duo processor, real-time
AVC/H.264 encoding is difficult.
