Abstract: The following configuration is preferable for providing a digital broadcast-enabled recording and reproducing device involving no lip-sync error and offering good usability. For example, the recording and reproducing device includes a receiver that receives digital broadcast data, a video/audio signal generator that generates a video signal and an audio signal included in the digital broadcast data received by the receiver, an image processing unit that executes image processing of the video signal input from the video/audio signal generator; and a delay unit that receives the audio signal generated by the video/audio signal generator to adjust time lag between the received audio signal and the video signal processed by the image processing unit.

Abstract: A broadcast receiver includes a tuner section for receiving a broadcast program, an MPEG decoder 126 for converting a signal coming from the tuner section into a given format, and a hard disk drive (HDD) for recording the converted digital signal. In the broadcast receiver, a HDD medium of the HDD for recording the received broadcast program has, separately, a stream area for storing stream data as a video/audio signal, and a management data area for storing management data other than the stream data, and these areas are formatted by each different given unit. With such a structure, the broadcast receiver becomes highly-usable, requiring less time for the search operation on an HDD at the time of system startup. There is also a method for recording broadcast programs received by the broadcast receiver, and an information recorder for such use.

Abstract: A highly-operable receiver, which shortens search operations on an HDD upon startup, a recording method thereof, and an information recorder therefor are described. The broadcast receiver includes a tuner portion for receiving a broadcast program, an MPEG decoder for converting a signal from the tuner portion to a predetermined format, and a hard disk drive (HDD) for recording the converted digital signal. Whether power was turned off normally at last use is determined when the power supply is turned on. If the power supply was turned off normally at last use, a bitmap for the HDD recorded upon the last power shut-off is input; if not, new bitmap information is created. Thus, the writing/reading operations of the HDD are better managed.

Abstract: It is necessary to provide a data recording apparatus that records a digital broadcast and facilitates the editing of recorded data. It is also necessary to provide a data recording apparatus that makes it possible to achieve high-quality playback of edited data with increased ease. In accomplishing these and objects, there is provided a data recording apparatus for recording a digital broadcast. The data recording apparatus comprises first recording means for recording externally input stream data, which is in transport stream (TS) format, onto a recording medium, and second recording means for generating data in program stream (PS) format in accordance with the TS format data and recording the generated PS format data onto the recording medium. The PS format data is edited in such a manner that the associated editing information is reflected in TS format data playback.

Abstract: In a data recording/reproducing unit, an identification of the storage unit is validated, to prevent circumvention of copy protection by unauthorized replacement of the storage unit. For example, when the power of a television receiver 100 is turned on for the first time, the controller 150 reads out a HDD serial number stored in a HDD 140, and then writes the number to a flash memory 160. While the receiver 100 is ON, the controller 150 acquires the HDD serial number stored in the HDD 140 periodically or every time there is an attempt to access the HDD 140. Then, the controller 150 compares the acquired HDD serial number to the HDD serial number in the flash memory 160. If the result of the judgment is negative, the controller 150 disallows the use of the HDD 140.
