The D / A converter 20 converts the digital audio data from the audio decoder 16 into an analog signal, and outputs audio from the audio output unit 21 that is a speaker.

  The storage unit 24 uses a recording medium such as a non-volatile memory or a hard disk in order to hold a recorded program information list (to be described later) and various settings by the user even when the apparatus is turned off.

Next, a recorded program information list, a connected recording / playback device list, and a scheduled recording program list for centrally managing recorded programs will be described.
The recorded program information list 50 is stored in the storage unit 24. As shown in FIG. 2, the program ID (program identifier) 51 unique to the list, the program name 52, the broadcast channel 53 on which the program is broadcast, the broadcast Date and time 54, detailed information 55 such as performers, recording medium type and recording medium ID (recording medium identifier) 56 on which the program is recorded, connected recording / playback device name 57, recording start position information 58, recording end position information 59, one Each item includes a scene icon cut time 60 and a one scene icon 61.

  The television receiver 10 iconsize one scene of a program for the purpose of helping recall the contents of the program when displaying the list of programs. Therefore, in order to provide a link to the scene cut time and one scene icon for that purpose, items of a one scene icon cut time 60 and a one scene icon 61 are provided. The link to the icon directly designates the location in the recording medium in the case of a randomly accessible medium such as HDD, BD, etc., and in the case of D-VHS, refers to the image data separately stored in the storage unit 24 at the time of recording.

  A connected recording / playback device list including the recording medium identifier 56 and the connected recording / playback device name 57 in the recorded program information list 50 is also stored in the storage unit 24. This connected recording / playback device list is included in the connected recording / playback device list when an externally connected recording / playback device is connected to the television receiver 10 through a network based on the IEEE1394 interface 22 or the like. If not, the information of the connected recording / playback device is added to the connected recording / playback device list.

Next, as a case where program information is added to the recorded program information list,
1) When a user performs a recording operation in units of programs based on EPG data from a television receiver 10 to an externally connected recording / playback device through a network based on the IEEE 1394 interface, etc.
2) When the recording medium loaded on the externally connected recording / playback device on the network based on the IEEE 1394 interface or the like is a disk medium and a program that does not exist in the recorded program information list 50 is included,
There are two ways.

  In the former case, the user first selects a program to be reserved for recording from the EPG on the GUI, and selects a recording / playback device as a recording destination from the recording / playback device list. The selected scheduled recording program is added to the scheduled recording program list 70 as shown in FIG. As the attributes of the scheduled recording program list 70, the values of the respective columns shown in FIG. 3 are essential. That is, the program name 71, the broadcast channel 72, the broadcast date and time 73, the detailed information 74 such as performers, the device name 75, and the one-scene icon cut time 76 are configured. 75 is set according to the recording / playback device selected by the user.

  Here, the one scene cut time can be selected to use a default value or set by the user. When performing a recording operation based on a recording reservation, first, if an attribute of the recorded program information list has the same type of attribute as that of the reserved recording program list, it is used, and for other attributes, an appropriate attribute immediately before the recording start time is used. The time is set according to the procedure as shown in FIG. 4 and added to the recorded program information list when the recording is completed.

  More specifically, the recording preparation is started, and the television receiver 10 and the external recording / playback devices 28, 29, and 30 are turned on (step S11). A program identifier 51 is set from the recorded program information list 50 (step S12). The program identifier 51 is recorded on the recording media of the external recording / playback devices 28, 29, and 30, and it is confirmed whether the recording media ID 56 has been set (step S13). If already set, the recording medium identifier is acquired (step S15). If not set, the recording medium ID is set at the head of the recording medium (step S14), and the recording medium identifier is acquired (step S15).

  The recording start position is acquired from the recording medium (step S16), and it is confirmed from the information of the recording date and time 54 in the recorded program information list 50 whether it is the recording start time (step S17). If it is the recording start time, recording of the external recording / playback device is started (step S18). It is confirmed whether the time is one scene cut time (step S19). If the one scene cut time is reached, the recording medium type is confirmed (step S20). It saves in the memory | storage part 24 and acquires a preservation | save location (step S21). If it is not the recording medium type in the recorded program information list 50, the one-scene cut position is acquired. (Step S22).

  When the recording end time comes (step S23), the recording ends (step S24), the recording end position is acquired (step S25), and added to the recorded program list (step S26).

  The recording medium identifier is used when an existing standard exists according to the recording medium, and a unique number or the like is set in the recorded program information list otherwise. In addition, the recording medium type used here is set to correspond to the connected recording / playback device from the connected recording / playback device list.

  In the latter case, first, when the recording medium identifier of the recording medium read into the connected recording / reproducing device is not set, the same means as the above means is set on the recording medium side. Among the attributes of the columns 51 to 61 in FIG. 2, the one scene icon cut time of the column 60 is set to a default time, and the reference to the one scene icon of the column 61 is a disc medium that can be randomly accessed by the recording medium. Therefore, the position information of the recording medium at that time is set. The device name is set to the device name of the connected recording / playback device. Other attributes are appropriately set from program information defined in the recording disk in accordance with standards such as AV / C.

Thus, when a program recording operation is executed on the external recording / playback device by the operation unit 27, the recorded program information is sequentially stored in the storage unit 24, so that the recording operation is performed from the television receiver 10 to the external recording / playback device. All recorded program information can be centrally managed without being caught by recording / playback devices and recording media, and at the same time, a user can easily find a desired program from the recorded program information and execute a desired operation. .
Further, since the recorded program information recorded in advance on a plurality of recording media read by the plurality of external recording / playback devices is sequentially recognized and stored in the storage unit 24, a recording operation can be performed from other than the television receiving apparatus 10. The recorded program information that has been performed can also be centrally managed.

  Next, display means for displaying a program registered in the recorded program information list will be described. As shown in FIG. 6, displays 81 and 82 based on systematic classification according to the recording / playback device 57, the recording media identifier 56 of the recorded program information list 50, and the recording media type attributes obtained from the recording / playback device list. , 83, and by displaying, for example, one-scene icons 84, 85 for each program, the program information can be browsed efficiently.

  The user selects a specific recorded program from the list of recorded programs displayed as described above on the GUI, so that a recording / playback device including a recording medium on which the program is recorded can be transmitted through a network based on the IEEE 1394 interface or the like. Remote operation can be performed. When the operation is executed, after confirming the connection of the corresponding recording / playback device and the coincidence of the recording media identifiers as shown in the figure, the operation selected by the user is executed on the recording / playback device.

Processing when the recording / playback apparatus is operated will be described with reference to the flowchart of FIG.
The user uses the operation unit 27 to operate the recording / playback device (step S31). The system control unit 26 confirms the connection of the recording / playback device that records the playback target program via the IEEE 1394 interface 22 (step S32). If the connection cannot be confirmed, the recording medium type data corresponding to the recording / reproducing device is acquired from the recording / reproducing device list stored in the storage unit 24 (step S33). If it is possible to confirm the connection of the recording / playback device to be played back, the process proceeds to step S39 to start the recording / playback device.

The system control unit 26 checks whether there is another recording / playback device corresponding to the recording medium type in the recording / playback device list (step S34). If there is another recording / playback device, it is confirmed whether the recording / playback device is connected (step S35). If the recording / playback device is connected, the process proceeds to step S37.
If there is no other recording / playback device in step S34, or if the recording / playback device is not connected in step S35, the user is requested to connect a recording / playback device corresponding to the recording medium type (step S36).

  In step S37, the system control unit 26 displays a list of corresponding connected recording / playback devices on the image display unit 19, and requests the user to select a recording / playback device to be used (step S37). When the user selects a recording / playback device from the operation unit 27, the system control unit 26 updates the recording / playback device attribute value in the recorded program information list stored in the storage unit 24 to the selected recording / playback device ( In step S38, the recording / playback device is activated (step S39).

  The system control unit 26 confirms whether the recording medium identifier of the recording medium in the activated recording / reproducing device matches the recording medium to be reproduced (step S40). If they match, the process performed by the user using the operation unit 27 is performed on the recording medium (step S42). If they do not match, a request is made to load the recording medium corresponding to the user onto the recording / playback device (step S41).

The operations performed are:
1) Move to the recording start position using the recording start position information (cue),
2) Use the recording end position information to move to the recording end position.
3) Cue playback using the recording start position information,
The following three operations are prepared. Further, not limited to the operations defined here, such operations may be executed when the recording / playback apparatus supports operations such as deleting a program according to a standard such as AV / C.

In addition, regarding the one scene icon, the user can reset a specific scene as a one scene icon during playback of a program in the recorded program information list. At this time, the time of the scene selected by the user is the one scene in column 60 of FIG. The icon time is set, and the scene image at that time (in the case of non-disc media that cannot be accessed randomly) or position information in the disc (in the case of disc media that can be accessed randomly) is used as a reference to the one scene icon in column 61. Will be reset. That is, when the recording medium cannot be randomly accessed according to the set image position time, the image at the image position time is stored in the storage means, and the storage position is set as the image position information in the recorded program information. Further, when the recording medium can be randomly accessed according to the set image position time, the position information within the recording medium is set as the image position information in the recorded program information.
It is also possible to delete unnecessary program information from the program list by GUI operation of the recorded program list.

  Thus, since the recorded program information is displayed together with the one-scene cut image, the user can recall the contents of the program based on data that is relatively smaller in capacity than the moving image data called image data.
