Everything you said is right on but a small addition: RealVideo, and Sorensen Video 1/Spark were based on h.263 drafts. Sorensen Video 3 was based on the h.264 draft. It's interesting because h.263 (coming out of the ITU-T) was developed for video conferencing like h.261. Real and Sorensen adapted it to streaming/disc delivery. The MPEG-4 spec was the first time the VCEG and MPEG got together and put the peanut butter and chocolate together from the start. It's maybe obvious in hindsight but I think it was the first time the needs of video conferencing, streaming, and disc/"digital" delivery really overlapped in terms of devices and environment. |
