ent Technologies. There are many important software-only codecs on the market, too. These include White Pine's Enhanced CU-SeeMe, Intel's Indeo, H.324, and others. At the time of this writing, the leading video communication codec choices conform to the ITU-T's various codec recommendations. These recommendations are referred to as the H.32X family of videoconferencing codecs. They include compression algorithms that are designed for transmission over ISDN-B channels, over LANs, and over POTS. The next chapter presents a thorough discussion of these codecs and the standards that define them. Coding and Compression CHAPTER 6 REFERENCES Brooks, John.
