Experimental Digital VCR with New DCT-Based Bit-Rate Reduction and Channel Coding
The number and the size of recording bits of a VCR should become smaller for it to become more compact and long-playing. The authors have achieved a data rate of 28 Mbits/s for a component coded video which normally requires approximately 200 Mbits/s, maintaining a high picture quality with less noticeable degradation by using a new DCT(discrete cosine transform)-based bit-rate reduction method. The authors have developed a data format based on the triple Reed-Solomon product code and a new 8/14 modulation scheme to make the recording density higher. An experiment has shown the feasibility of the authors' new system concept.
