Abstract

The HDTV studios of the future will require magnetic recorders for the acquisition, storage, editing and broadcasting of HDTV material. Inside these studios, the HDTV signal will probably be a digital signal. Due to the high bit rate of digital HDTV, recorders without bit- rate reduction will be mechanically complex and these recorders will have a limited playing time. The complexity of the recorder can be decreased, and the playing time can be increased, by reducing the bit rate of the HDTV signal before it is recorded on tape. This paper first discusses the constraints on bit-rate reduction for professional HDTV recording and then goes on to describe the results obtained with a bit-rate reduction method called motion-adaptive intraframe transform coding.
