H. 261 - Wikipedia H 261 is an ITU-T video compression standard, first ratified in November 1988 [1][2] It is the first member of the H 26x family of video coding standards in the domain of the ITU-T Study Group 16 Video Coding Experts Group (VCEG, then Specialists Group on Coding for Visual Telephony)
Visual Coding VCEG - ITU ITU-T H 120 Codecs for videoconferencing using primary digital group transmission was the first international standard for digital video compression It was originally developed in 1984 and substantially revised in 1988, including such pioneering developments as motion-compensated inter-frame coding

Chapter 10: H. 261 and H. 263 | GlobalSpec ITU-T H 261 was the first video compression and decompression standard developed for video conferencing Originally designed for bit rates of p 64 kbps, where p is in the range 1 30, H 261 is now the minimum requirement of all video conferencing standards, as shown in Table 10 1
Video Compression - University of Texas at Austin Compress color motion video into a low-rate bit stream at following resolutions: QCIF (176 x 144) CIF (352 x 288) Inter and Intra Frame coding Motion Vectors H 261 The ITU-T recommendation H 261 (a k a px64), is for video telephony over ISDN lines
H. 261 - Cloudinary H 261 is an International Telecommunication Union (ITU-T) video coding standard introduced in 1988 It was the first widely adopted codec for video conferencing and has since served as the foundation for subsequent video compression standards
H. 263 vs. H. 264: Decoding the Differences in Video Compression H 264: Advancing the Standards of Video Compression Also known as MPEG-4 Part 10, Advanced Video Coding (AVC), H 264 was introduced in 2003 by the ITU-T Video Coding Experts Group in conjunction with the ISO IEC Moving Picture Experts Group (MPEG)
