Patent ID: 8218949

Claim:
A video information recording device comprising: an encoder including a processor for encoding, using a first coding method, a first video signal to produce first encoded data, the first video signal including a plurality of pictures, such that the first encoded data is produced by completely encoding the plurality of pictures of the first video signal using the first coding method; a generator for generating partial data from the same plurality of pictures of the first video signal by performing at least a partial encoding of the same plurality of pictures of the first video signal using a second coding method, the second coding method being different from the first coding method; and a recorder for recording, into a memory, (i) the first encoded data encoded by the encoder using the first coding method and (ii) the partial data generated by the generator using the second coding method, wherein, the recorder does not record into the memory a complete encoding, using the second coding method, of the same plurality of pictures of the first video signal.
