    摘要: An information processing apparatus controls first and second coded streams to be output in a form in which the first and second coded streams are connected to each other. The apparatus includes an operation-input acquiring unit for acquiring an operation input representing a playback portion of both coded streams to be played back, a storage unit for storing coded streams including both coded streams, a transfer-control unit for controlling transfer, to the storage unit, of portions of both coded streams for the operation input acquired by the operation-input acquiring unit, a coded stream necessary for decoding the portions of both coded streams for the acquired operation input, a decoding unit for decoding both coded streams stored in the storage unit to generate image data, and a commanding unit for commanding an image-data output time at which the image data generated by the decoding unit is output.

    摘要: The present invention allows usable information to be selected by comparing information regarding encoding with conditions regarding encoding processing. When delay modes, picture structures, and pulldown modes do not match each other between previous encoding time and re-encoding time, parameters are not reused. When they match and image frames do not match, a picture type is reused. When a bit rate in the previous encoding is smaller than that in the current encoding and a chroma format is larger than the current chroma format, a picture type and a motion vector are reused. When the conditions are not satisfied, parameters are supplied and received and a determination is made as to whether or not chroma formats match each other. When the chroma formats do not match each other, picture-type information, motion-vector information, and quantization-value information are reused. When the chroma formats match each other, stream data input to a decoding unit is output. The present invention can be applied to an encoding unit, an encoding device, or a transcoder.

    摘要: An information processing apparatus decodes compression-coded video data including I-pictures, P-pictures, and B-pictures. The information processing apparatus includes at least one decoder decoding the compression-coded video data, a supply controller controlling the supply of the compression-coded video data to the decoder, and a controller controlling processing executed by the supply controller and the decoder. The decoder includes a bank memory for storing decoded picture data, and the controller controls the timing at which a picture stored in the bank memory is released by changing the value of a first counter indicating a number of times for which the picture stored in the bank memory is referred to when a P-picture or a B-picture is decoded by the decoder.
