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.

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.
摘要翻译： 当数字广播被记录在存储介质中时，首先根据预先已知的数字化广播数据的比特率和记录时间来计算存储介质的所需容量。 如果存储介质的剩余容量小于存储介质的所需容量，例如，在新存储的广播上执行帧速率抽取和像素减少，则对广播执行重新编码处理，并且 则所得到的广播被存储在存储介质中。 如果存储介质的剩余存储容量大于存储介质的所需容量并因此保留，则对要存储的广播执行帧内插和像素插值，然后对所得到的广播进行重新编码处理 以提高其图像质量。 结果，可以确保在存储介质中记录广播数据。

摘要： A frame memory is provided which has five fields each having N slots, and three additional slots. Each slot has a storage capacity to store eight image lines. Four fields of the five fields serve to store motion compensation reference frames. The remaining one field and the three additional slots are used for B-picture interlace conversion. Disposed in a control unit are a slot control memory, a write slot pointer, and a read slot pointer. For an image output unit to acquire information from the frame memory in a correct slot order, the contents of the slot control memory are updated at the time of performing write operation to enter information into the frame memory by a bit stream analysis unit.

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.
