摘要： A removable medium includes a data separator configured to separate data input from a digital camera which is an external apparatus into storage data and display data, a data storage configured to store the storage data as a content, and a medium information display configured to display the display data as an image. The medium information display includes, for example, electronic paper in order to, even after the removable medium is removed from the digital camera, continue to display an image as it was displayed immediately before the removal of the removable medium. The removable medium further has a function of outputting the display data of the medium information display to the outside.

摘要： Even in the case of copying contents data on a recording medium not compliant with copyright protection, in order to enable the data to be moved to a recording medium compliant with copyright protection, key data to encrypt the contents data is generated per contents data and held in a contents encrypting key memory section 106 in the recording/reproducing device. The contents data is encrypted by the key data in a contents encrypting section 103, while at the same time the key data is encrypted in a key encrypting section 107, both data being recorded together on the HDD 111 not complying with copyright protection. When the contents data is moved to a DVD-RAM 112 of the copyright protection non-compliant recording medium, the key data held in the contents encrypting key memory section 106 is deleted and the contents data cannot be reproduced even by the HDD-DVD recorder 102.

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： 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.
