3. H.263 - Wikipedia

   en.wikipedia.org/wiki/H.263

   H.263 was developed as an evolutionary improvement based on experience from H.261 and H.262 (aka MPEG-2 Video), the previous ITU-T standards for video compression, and the MPEG-1 standard developed in ISO/IEC. The first version of H.263 was completed in 1995 and provided a suitable replacement for H.261 at all bit rates. It was further enhanced ...
