- I've got a copy of the original MIT HDTV proposal to the FCC (dated
- February 1991), which clearly lays out the intraframe coding as subband
- coding. However, in the latest IEEE Micro ("Digital Video Coding Techniques
- for U.S. High-Definition TV"), it has the now renamed MIT/GI system using a
- DCT. The reference to the system is from an April 1992 document, so I
- assume that somewhere between 2/91 and 4/92, MIT decided that the earlier
- system with subband coding wasn't going to work out. Is this what happened?
- Does anyone know why? Finally, is the current compression method in the
- MIT/GI Channel Compatible DigiCipher MIT's or GI's?
-
- Thanks in advance to anyone who can help clear up the confusion
