摘要： In the case of performing NR (noise reduction) and scaling on video signals, the NR buffer 104 is formed by, for example, five line memories. An NR section 103 and a scaling section 105 are controlled by a control section 108. The control section 108 controls the NR section 103 and the scaling section 105 such that video signals subjected to noise reduction by the NR section 103 and corresponding to one line are output from the NR section 103 to an arbitrary one of the line memories of the NR buffer 104 and video signals corresponding to a plurality of lines and stored in the line memories of the NR buffer 104 except for the line memory to which the video signals corresponding to one line have been input from the NR section 103 are input from the NR buffer 104 to the scaling section 105. Accordingly, noise components of video signals are reduced with the memory size reduced.

摘要： A decode control section 103 sets allocated times required for decoding a plurality of coded streams in processing units based on input stream information on the plurality of coded streams. A decode section 101 decodes the plurality of coded streams while switching the input between the plurality of coded streams based on the allocated times.

摘要： There are included an image decoder (10) for decoding encoded image data; a processor (11) for performing both a partial decoding of encoded image data and a control of the image decoder (10); an internal command memory (12) for storing programs to be executed by the processor (11); an external command memory (13) for storing all of programs to be transferred to a RAM area of the processor (11); and a frame memory (14) for storing decoded data outputted from the image decoder (10). The programs used for decoding the encoded image data are divided into functional module units. While the programs are interchanged from the external command memory (13) to the internal command memory (12) for each of predetermined command memory transfer unit during reproduction, the encoded image data is decoded.

摘要： Decoded data, which has been output from a decoder, is stored on storage so as to be presented or used for decoding another encoded data. A presentation method recognizer recognizes a presentation method for the decoded data. If the presentation method has been changed into a new presentation method, the recognizer sets the number of frame memories as required by the new presentation method. In that case, a memory allocator allocates the same number of sub-areas of the storage area as that set by the recognizer for the frame memories such that the sub-area previously allocated for the frame memory, on which the decoded data being presented is stored, is included in the sub-areas newly allocated.

摘要： An image signal reproduction apparatus and an image signal reproduction method that can reproduce video signals at high speed with stability. A skip decoding field counter is set on the basis of a factor by which the reproduction speed is multiplied and the number of fields included in one frame image. When decoding of coded data corresponding to one frame to be decoded is completed, it is judged whether the skip decoding field counter is larger than zero or not. When the counter is larger than zero, the number of fields corresponding to a picture to be skipped is subtracted from the counter, and when the picture to be skipped is I or P coded data, the decoding is instructed, while when the picture is B coded data, the skipping is instructed. These processes are repeated until the counter becomes 0 or smaller.
