How does H.264 compare with H.263?
H.263, created by the ITU, is primarily known as a video codec designed for low-latency video conferencing applications. H.264 has been adopted by the ITU as the successor to H.263 for these same low-latency video conferencing scenarios. H.264 provides much higher quality than H.263 across the entire bandwidth spectrum, thanks to advancements in technology since the introduction of H.263 more than a decade ago. H.264 is already being adopted in video conferencing solutions such as Apple s iChat AV in Tiger and products from Tandberg and Polycom, the two main suppliers of professional video conferencing systems.
