A content of Copy Once cannot be copied to an external device or the like, even for the purpose of making a backup. This is inconvenient for the user. However, if copying to another device for the purpose of making a backup is permitted, the content may be copied in an unauthorized manner. The present invention provides the hard disk recorder 100 that transmits the content to the backup device 500, sets an expiration time in the content stored in the hard disk recorder 100 itself, and deletes the content stored in the hard disk recorder 100 itself after the expiration time expires.

A Hard Disk Recorder (HDR) receives signals defining television programmes and programme schedule data. The HDR receives updated programme schedule data substantially constantly in a dedicated programme schedule data channel and outputs this data for display on a television screen. The HDR comprises a hard disk for recording programmes. A remote control selects programmes for recording from the displayed schedule. The HDR also receives schedule information included in each of the received television channels which information is used to control the hard disk to record pre-programmed programmes. The hard disk can simultaneously record two different television programmes received in different channels and to replay a currently broadcast programme offset in time. The HDR also receives transition signals indicating transitions between parts of programmes, such as advertisements and the “actual” programmes, which can be used to skip between transitions in recorded programmes replayed from the hard disk.

A quick-releasing structure is applied to a casing for installing a hard disk device. The quick-releasing structure comprises a spring plate, a handle, and two shock-absorbing members. The spring plate is connected to the casing; the two ends of the handle are coupled to the spring plate; two shock-absorbing members are connected to the two ends of the spring plate for fastening the hard disk device and producing shock-absorbing effect. By pulling the handle, the two ends of the spring plate being moved away from the casing, and the two shock-absorbing members being moved to release the hard disk device.

The invention provides a method for restoring lost data in abnormal shutdown. The method comprises the following steps of: A. judging that the current shutdown before start is abnormal according to stored log information, and determining that latest writing segment information corresponding to recording files writing recording data before abnormal shutdown; B. determining a start position point for carrying out frame analysis according to start offset in the latest writing segment information and final offset of the segment; C. starting to carry out frame analysis from the start position point, and updating the final offset and the final time of the segment according to a frame analysis result and the start position point; and D. taking the final offset and the final time of the segment after updating as reference points for a data storage position after the current starting. The invention also provides a hard-disk recorder. By adoption of the method and the hard-disk recorder provided by the invention, the data storage position before abnormal shutdown can be positioned, and the lost data can be restored.

A Hard Disk Recorder (HDR) (3) is arranged to receive signals signals defining television programmes and television programme schedule data. The HDR receives updated programme schedule data substantially constantly in a dedicated programme schedule data channel. The HDR is arranged to output the programme schedule data for display on a television screen (2). The HDR comprises a hard disk (16) for recording received television programmes. A remote control (28) is provided to select television programmes to be recorded from the displayed programme schedule. Furthermore, the HDR is arranged to receive additional programme schedule information included in each of the received television channels which information is used to control the hard disk to record pre-programmed television programmes according to schedule. The hard disk is operable to record simultaneously two different television programmes received in different channels. Also, the HDR is operable to replay a currently broadcast programme offset in time. The time offset can be overcome by playing back the part of the programme inside the time offset at an increased frame rate. Furthermore, the HDR is arranged to receive transition signals indicating transitions between parts of programmes, such as transitions between advertisements and the “actual” programmes. The HDR is operable to use these transition signals, for example, to skip between transitions in previously recorded programmes replayed from the hard disk.

A channel switching method in a broadcast recorder integrating a set-top box and a hard disk recorder. At the request of the user, channels tuned to by a secondary tuner are switched and other broadcast programs received therethrough are output, while a broadcast program being received through a primary tuner is recorded on a recording medium. If the channel recorded on the medium is identical to the channel to which the user has requested channel switching, a time shift operation is performed to reproduce the stored broadcast program while storing the broadcast program being received through the primary tuner. Accordingly, if the user desires to return to a channel providing a desired program when viewing programs of other channels, the user can easily resume viewing the desired program, without missing any part of the desired program, which has been received while the user views the programs of the other channels.

A video display device outputs display device information including physical resolution of a display device included in the video display device and subpixel information to a hard disk recorder through HDMI (High Definition Multimedia Interface) cable. A receiver of the hard disk recorder receives the display device information and outputs the received information to an image processor. The image processor converts resolution of an image data stored in HD into physical resolution of the display device included in the display device information to output the image data. The image processor performs processing in subpixel level based on the subpixel information included in the display device information in converting the resolution.

A channel switching method in a broadcast recorder integrating a set-top box and a hard disk recorder. At the request of the user, channels tuned to by a secondary tuner (27) are switched and other broadcast programs received therethrough are output, while a broadcast program being received through a primary tuner (20) is recorded on a recording medium (26). If the channel recorded on the medium (26) is identical to the channel to which the user has requested channel switching, a time shift operation is performed to reproduce the stored broadcast program while storing the broadcast program being received through the primary tuner (20). Accordingly, if the user desires to return to a channel providing a desired program when viewing programs of other channels, the user can easily resume viewing the desired program, without missing any part of the desired program, which has been received while the user views the programs of the other channels.

A controller to be connected via an IEEE 1394 serial bus to two or more hard disk recorders. When a user selects an attribute of program files to be deleted by using an operation unit, a microprocessor in the controller searches for program files corresponding to the attribute, which is selected by the user via the operation unit, among program files stored in any of the hard disk recorders. When program files corresponding to the selected attribute are found as a result of the search, the microprocessor creates a list of the program files corresponding to the selected attribute based on the result of the search. Then, the microprocessor sends a control command to delete each of the program files in the list from a hard disk recorder on which the each program file is stored via an IEEE 1394 interface to the hard disk recorder. Accordingly, the program files in the list are deleted from the hard disk recorders on which the program files are stored.
