Understanding H.264 Video Compression

How the new H.264 standard for surveillance video compression works, and when to use it


H.264 offers significant benefits to the user and system designer. However, the extra complexity of the implementation comes at extra cost. So H.264 will not replace MPEG-4 overnight, but sit alongside it providing a wider choice of solutions to the end user. Even though MPEG-4 and H.264 compression standards are not compatible, IP networks allow both systems to co-exist and many video management and recording software systems can directly understand both bitstreams.
