摘要： The data recording and reproducing apparatus comprises a transcoding module and a recording and reproducing module. The transcoding module transcodes a video or audio signal based on one compression method to a signal based on another compression method, the video or audio signal being inputted through a tuner. The recording and reproducing module records, to a recording medium, the transcoded video or audio signal together with the inputted video or audio signal, the transcoded video or audio signal having been transcoded by the transcoding module. The recording and reproducing module records one of the video or audio signals, which are identical but based on different compression methods, with the other video or audio signal being written to the recording medium as a hidden file.

摘要： An object of the present invention is to provide a digital signal recording and playback apparatus for, even in the case of a program whose recording is not permitted (for example, Never Copy), performing, on the digital signal receiving side, recording and playback control that is limited to time shifting. In order to achieve the above object, there is provided a digital signal recording and playback apparatus that writes digital signals to different recording areas on the recording medium, the recording areas including a first recording area to which an ordinary digital signal is written, and a second recording area to which an encrypted digital signal having a copy restriction control flag is written, the digital signal recording and playback apparatus erasing, under specified conditions, an encryption key of the digital signal written to the second recording area.

摘要： In a DVD video player with a built-in CD-R drive, until it reaches the state that the data of an optical disk can be reproduced, the output is switched into the reproduction output from a flash memory, a record medium that is quick to start reading. This makes it possible to develop user interfaces such as: voluntarily reproducing an audio information from the flash memory to add music sounds or sounds with special effects to the screen saver, in replacement of the optical disk drive that cannot read data during the screen saver being in operation or being in standby; reproducing the sounds with special effects; reproducing click sounds in response to a key input from the key or the remote control unit; and announcing to inform of the state to the user.
