摘要： A formatter 2s13 is provided and, when a code sequence which matches a part (‘00’) of the head of a predetermined code sequence detected by a start code prefix detection unit 2s3, is detected, the start code prefix detection unit 2s3 detects the residual part (‘00’, ‘00’, ‘01’, ‘E0’) of the detected predetermined code sequence to detect a pattern of (‘00’, ‘00’, ‘00’), and the formatter 2s13 outputs one (‘00’). After the boundary of packets is defined, amongst data which are not transferred to a decoding buffer 2s9, data corresponding to code sequences other than the code sequence (‘00’, ‘00’, ‘01’, ‘E0’) indicating the packet boundary are output to the decoding buffer 2s9. Therefore, when separating a coded and multiplexed signal, control of an input buffer reading control circuit 2s4 is simplified, and thereby the hardware scale is reduced, resulting-in an inexpensive apparatus for reproducing a digital code sequence.

摘要： In order to cope with format conversion of user data, the bit rate value and VBV (Video Buffering Verifier) buffer size value in a sequence header of an input code and the VBV delay value in a picture header of the input code are modified to obtain an intermediate code (305 to 309), and additional information (300) is generated for distinguishing GOP (Group of Pictures) user data (307) from the other main data. A VBV buffer simulation is performed using this additional information (300) to multiplex the GOP user data in a picture user data region to a data amount such that the operation does not fail, whereby an output code is generated.

摘要： When a digitized broadcast is recorded in a storage medium, a required capacity of the storage medium is firstly calculated on the basis of a bit-rate of digitized broadcast data and a recording time which is known in advance. If the remaining capacity of the storage medium is smaller than the required capacity of the storage medium, for example, a frame rate decimation and pixel reduction are performed upon a broadcast to be newly stored, a re-encoding processing is performed for the broadcast and then the resultant broadcast is stored in the storage medium. If the remaining storage capacity of the storage medium is larger than the required capacity of the storage medium and thus remains, a frame interpolation and pixel interpolation are performed for the broadcast to be stored and then a re-encoding processing is performed for the resultant broadcast in order to improve its image quality. As a result, recording of the broadcast data in the storage medium can be ensured.

摘要： A variable length encoding apparatus such as an encoding apparatus using the MPEG standard, wherein without degrading the precision of quantization step, the generated code bit amount is limited. Encoding is performed at the quantization step of required picture quality by an encoding part 106, and a bit stream 141 is written in an external memory 101. The generated encoded bit amount is measured from the increment of a write pointer 121 increased because of the writing in the external memory 101 by a control unit 107. If the amount is larger than a preset value, the data is replaced with data leading to the same decoding result as those of the preceding or following reference picture by using a replacement pattern in accordance with the picture type and the position on a times series, and the data is written in the external memory 101, thus outputting the data as an output bit stream 111 controlled to the generated code amount within an upper limit value.

摘要： The present invention discloses an MPEG decoder for reproducing moving picture data. A first frame memory (FM0) and a second frame memory (FM1), each of which is composed of 2N slots, are provided. A third frame memory (FM2) is provided which is composed of N+4 slots. Each slot is provided with a memory capacity of eight lines. FM0 and FM1 each have a 1-frame memory capacity for storing reference frames for motion compensation. FM2, on the other hand, has a memory capacity of half a frame+32 lines for B-PICTURE interlace conversion. A slot control memory (SM) is further provided which is composed of 2N+6 words each of which stores a respective slot number of FM2. For an output section to read the slots of FM2 in the correct order, the contents of SM are updated by an control section at the time of the writing of FM2 by a decoding section.

摘要： A recording/reproduction apparatus includes a first recording medium (a flash memory) having a first time that is required for the first recording medium to go from a low-power consumption state to a state in which recorded video data can be read out, and a second recording medium (an HDD or a DVD drive) having a second time that is required for the second recording medium to go from a low-power consumption state to a state in which recorded video data can be read out, where the second time is longer than the first time. When a video content is reproduced from the second recording medium in the low-power consumption state, the first recording medium is caused to go to a readable state while the second recording medium is not in a readable state, and a leading portion of the content is reproduced from the first recording medium. Thereby, a start-up time of the second recording medium that is required until reproduction is permitted is concealed from the user, and the user's reproduction request is immediately responded.
