Video signal recording apparatus and video signal regenerating apparatus |
摘要 |
To a conventional video signal recording apparatus, there are added additional information generating means and data replacement means for replacing data at a specified position in compressed data with additional information generated by the additional information generating means. This enables to provide a video signal recording apparatus and a video signal regenerating apparatus which are able to increase transmissible information content, an image coding apparatus that executes high-efficiency non-linear quantization at a small circuit containing no quantization table and also prevents error propagation; and an image decoding apparatus for regenerating coded data obtained in the image coding apparatus.
