An image processing apparatus includes a plurality of decoders, each decoding a predetermined region of each frame forming coded stream and an output unit receiving pixel data obtained as a result of the decoding processing by the plurality of decoders and combining the pixel data into decoded image data to output it. One subject decoder supplies, among pixel data obtained as a result of the decoding processing by the subject decoder, pixel data necessary for a different decoder to the different decoder, and also obtains, among pixel data obtained as a result of the decoding processing by the different decoder, pixel data necessary for the subject decoder from the different decoder. The subject decoder performs the decoding processing by referring to the pixel data obtained as a result of the decoding processing by the subject decoder and the pixel data obtained from the different decoder.

Image processing apparatus, image processing method, recording medium, and program

A motion picture film having digital audio data recorded in at least one sound track thereof. Such digital audio data includes a plurality of bytes of data each having 8 bits of data. Each respective bit of each byte of audio data is recorded in a sound track of the film in the film running direction and each byte is arranged side-by-side in a direction normal to the film running direction to form a compression processing block. C1 parity data is added to each such compression processing block and C2 parity data is added after a predetermined interval of plural compression processing blocks. Error correction may be performed by utilizing the C1 and C2 parity data for each compression processing block and at the predetermined interval of plural compression blocks.

Motion picture film and a technique for recording and/or reproducing

An information signal recording and reproducing apparatus having a reproducing head at a position anterior to a recording head by a distance corresponding to a predetermined time interval for recording an information signal on a recording medium and reproducing the recorded information signal. A test pattern signal is generated and delayed in a delay circuit by an amount determined by a control signal. An external delay-factor device receives the delayed test pattern signal and imposes a further delay thereon. The phase of the delayed signal from the external delay-factor device and the phase of the test pattern signal are compared and the control signal is generated, such that the sum of the amounts of delay imposed by the external device and the delay circuit becomes coincident with the predetermined time interval. Thus, the desired phase adjustment can be automatically and rapidly achieved with precision.
