FIG. 6 is an explanatory diagram for explaining how the discontinuous portion is deleted.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration diagram showing the configuration of the image receiving recording system of the present invention. The image receiving recording system 100 includes an image receiving device 200 that receives a program and a recording device 300 that records the program. The image receiving apparatus 200 includes an image receiving apparatus main body 201, a remote controller 202, and the like. The recording apparatus 300 includes an apparatus main body 301 and a remote controller (not shown).

  The image receiving apparatus main body 201 is further received by the tuner section 210 that receives the program, the switch section 211 that receives the operation of the remote controller 202 and performs the switch operation provided in the image receiving apparatus main body 201, and the tuner section 210. A display unit 212 that displays the displayed program, a communication unit 213 that communicates with the recording apparatus main body 301, and a control unit 214 that controls each unit. Among these, the communication unit 213 transmits an operation command of the switch unit 211 or the remote control 202, for example, an operation command such as immediate recording (one-touch recording) described later via the control unit 214, or transmits information on the recording apparatus 300 side. Communication such as acquisition.

  The recording apparatus main body 301 receives a program image / audio signal and other information, a tuner unit 310 that inputs various operations, and an input display device 311 that displays the operation status, and the tuner unit 310 receives the operation status. The image capturing / compression device 312 for capturing and compressing the image / audio signal and other information of the recorded program, the storage device 313 for storing the program captured and compressed by the image capturing / compressing device 312, and the storage device 313 A data decompression device 314 that decompresses a program, a communication unit 315 that communicates with the image receiving device main body 201, and a control unit 316 that controls each unit are included.

  The control device 316 includes a controller such as a microcomputer or a high performance CPU that controls all functions of the recording device 300. The image capture / compression device 312 captures an image and compresses the data in the MPEG format. The compression format may be the current mainstream MPEG1 format, or may be an MPEG2 format compatible with high image quality or an MPEG4 format compatible with low bandwidth. Needless to say, other compression formats may be employed.

  The data decompression device 314 decodes the MPEG data compressed by the image capture compression device 312 into a television signal (NTSC system), and outputs a signal that can be viewed on the television. The output signal is displayed on the display unit 212 of the image receiving apparatus main body 201 through the communication unit 315 or an original cable connection.

  The storage device 313 includes a storage medium such as an HDD, a DVD, or a memory, and stores compressed program data (image / audio signal and other information). Depending on the setting, these programs always record programs on the channel when the main power is turned on, or programs on all channels. The continuous recording can be canceled by the control of the control device 316 or the like. In the case of continuous recording, when the capacity overflows or the storage time limit has passed, it is overwritten and repeatedly recorded. That is, when recording constantly, endless recording is performed.

  The image receiving apparatus main body 201 or the remote control 202 is provided with a switch that is used when the recording device 300 immediately records a program being viewed by the user through the display unit 212 (hereinafter referred to as one-touch recording as appropriate). Yes. FIG. 2 is a schematic diagram schematically illustrating the external configuration of the image receiving device main body 201, the remote controller 202, and the recording device 300. In the figure, a state in which the one-touch recording button B1a for performing immediate recording is arranged on the image receiving apparatus main body 201 and the one-touch recording button B1b is arranged on the remote controller 201 is shown. Hereinafter, the one-touch recording button B1a and the one-touch recording button B1b may be collectively referred to as a one-touch recording button B1. The one-touch recording button B1 is a single button in the figure, but is set as a combination operation of existing buttons such as a combination of existing buttons, for example, simultaneous pressing of a channel up / down button or simultaneous pressing of a volume up / down button. You can also.

  Next, an operation flow when the one-touch recording button B1 is pressed will be described. FIG. 3 is a flowchart showing an operation flow when the one-touch recording button B1 is pressed. When the one-touch recording button B1 is pressed (step S501), the communication unit 213 of the image receiving apparatus 200 communicates with the communication unit 315 of the recording apparatus 300 to check whether the main power supply of the recording apparatus main body 301 is ON. (Step S502). When the main power supply of the recording apparatus main body 301 is OFF (step S501: NO), the control device 316 of the recording apparatus main body 301 turns on the main power supply of the recording apparatus 300 (step S503).

  When the main power source of the recording apparatus 301 is ON (step S502: YES), or when the main power source of the recording apparatus is turned ON in step S503, the communication unit 213 of the image receiving apparatus 200 includes the image receiving apparatus main body 201. The channel information of the program being displayed on the display unit 212 is transmitted to the communication unit 315 of the recording device 300, and the communication unit 315 of the recording device 300 receives this channel information (step S504). Subsequently, based on the channel information, the control device 316 of the recording device 300 changes the setting of the channel received by the tuner unit 310 (step S505). After changing the setting, the storage device 313 starts recording the program (step S506).

  Since the time from the pressing of the one-touch recording button B1 in step S501 to the start of recording in step S506 is transmission / reception of electrical information, recording can be started in a short time. Conventionally, even if you want to record immediately, for example when you turn on the power switch to watch TV and broadcast a program you want to save, check the current channel, look for the remote control on the VCR, It is necessary to turn on the main power of the VCR, adjust the channel, find and set a free tape for recording, and start recording. Since the user has performed a series of operations, recording is troublesome. It was happening that the content of the program that I wanted to record had already ended when I stopped doing it or was ready. According to the image receiving recording system 100, such a complicated operation is not required. Even when the remote control 202 is unknown by pressing the switch of the remote control 202 of the image receiving apparatus 200 at hand, the switch of the image receiving apparatus main body is pressed. Simple recording is possible immediately.

  Further, for example, the display unit 212 may be a touch panel instead of the one-touch recording button B1, and a configuration in which a recording instruction area is appropriately provided and immediate recording is performed by pressing the touch panel may be employed.

  On the other hand, the image receiving recording system 100 of the present invention can also be applied to an always-recording type video deck (recording apparatus) that is currently being developed. For example, even when the user forgets to select the continuous recording mode, the immediate recording can be started, or the user can easily perform the recording operation even when the back program that is always recorded is viewed and the program is immediately recorded. .

  When immediate recording is performed with the one-touch recording button B1, the recorded portion is important for the user and is often desired to be stored for a long period of time. Therefore, the image receiving recording system 100 according to the present invention sets the recording area to overwrite prohibition when immediate recording is performed by the one-touch recording button B1. FIG. 4 is an explanatory diagram for explaining a state in which the recording area is set to overwrite prohibition when immediate recording is performed by the one-touch recording button B1. In the figure, a program A composed of program contents A1, A2, and A3, commercials C1 and C2 inserted in the middle of the program, and a program B are shown being broadcast.

  When the one-touch recording button B1 is pressed halfway through the program content A2, the storage device 313 sets the recording area until A2 is terminated as an overwrite-inhibited area via the control unit 316 (see recording state (a)). ). In the case of continuous recording, even if a region of the same program content is identified based on structured data representing information such as the content of the program, and one-touch recording B1 is pressed in the middle of A2. It is also possible to set overwriting prohibition from the beginning of the program content A2 (see the recording state (b)). The control device 316 identifies whether the program content is the same. Further, depending on the setting, it is possible to set the overwriting prohibited area from the beginning of program A to the end of program A, that is, from program content A1 to program content A3. In this case, CM (C1) inserted halfway is set as an overwritable area in order to save capacity.

  When the image receiving recording system 100 is used for a long period of time, the continuity of data is impaired due to recording or the like in small pieces. This tendency becomes prominent due to the setting for overwriting and prohibition. If the continuity is deteriorated, it means that the accessibility is deteriorated when, for example, a DVD is used as a storage medium, which is not preferable. Therefore, the image receiving system 100 must have an editing function. Even in this case, the image receiving recording system 100 communicates between the communication unit 213 and the communication unit 315 included in each of the image receiving apparatus 200 and the recording apparatus 300, so that a simple editing operation is possible. The editing work will be described below.

  The image receiving recording system 100 enables the editing operation of the storage device 313 through the operation of the image receiving apparatus main body 201 or the remote controller 202. FIG. 5 is an explanatory diagram for explaining an external configuration of the image receiving recording system 100 when an editing operation of data in the storage device is performed. At the time of editing, the display unit 212 selects a communication unit from various disk information such as fragment information of the storage medium in the storage device 313, information on the overwrite prohibited area, recorded program information, and unrecorded part information. The storage medium structure (tags and search delimiter data) is displayed via 315 and the communication unit 213.

  Note that information on the storage media fragment information, overwriting-prohibited area information, recorded program information, unrecorded information, etc. is index-like information, so the amount of information is in comparison with the image / audio data of the program itself. Remarkably small. Accordingly, since the amount of communication between the communication unit 315 and the communication unit 213 is small, the processing load on the control unit 214 and the control device 316 can be reduced.

  In Japanese Patent Laid-Open No. 10-79916, “video recording device”, a video recording device capable of recording for a long time can overlook the entire recorded program and can quickly reproduce (cue) a necessary program. Is disclosed. However, this is not an operation from the recording device side through communication between the recording device and the image receiving device, nor is it a technique for improving the fragmentation of the program by the overwritable / prohibited setting. Therefore, Japanese Patent Laid-Open No. 10-79916, “Video Recording Device” is an invention different from the image receiving recording system 100.

  When it is complicated to perform various operations necessary for editing, a mark for selecting an operation is displayed on the screen of the display unit 212, and the mark is arranged on the selection button B2a arranged on the image receiving apparatus main body 201 or on the remote control 202. The work is selected by the up / down / left / right buttons of the selection button B2b provided, and the selection is determined by the determination button B3a disposed on the image receiving apparatus main body 201 or the selection button B3b disposed on the remote control 202. This increases operability and improves user convenience.

  As a specific editing operation, a merge operation / deletion operation when the storage medium is fragmented will be described. In FIG. 5, in the display unit 212, a portion where fragmentation has occurred is pointed out by an arrow at the bottom of the screen, and a state in which a deletion operation is selected is shown. In this case, the discontinuous portion is deleted by pressing the decision button B3. FIG. 6 is an explanatory diagram for explaining how the discontinuous portion is deleted. The deletion of the discontinuous portion corresponds to the defragmentation work of the computer hard disk. Note that the merge operation / deletion operation when the storage medium is fragmented may be automatically performed.

  As another example, when the storage medium consists of a low-speed large-capacity memory and a high-speed small-capacity memory, the program content to be stored for a long period of time is relocated from the large-capacity memory that can be allocated for continuous recording to the small-capacity memory You can also. At this time, compression storage may be performed.

  Since the image receiving recording system 100 is configured to perform one-touch recording from the image receiving device 200 side, it is not necessary to set the recording device as in the conventional case, and even when the content of a program to be recorded suddenly starts, recording can be easily performed. It becomes. In addition, since such a program that needs to be recorded immediately needs to be stored as it is, it is set to prohibit overwriting so that the user does not overwrite it by mistake. Further, since the image receiving recording system 100 performs communication between the image receiving apparatus 200 and the recording apparatus 300, the state of the storage medium in the storage apparatus 313 is displayed on the display unit 212, and the image receiving apparatus 200 side is viewed while viewing this display. A simple editing operation such as a merge operation or a delete operation can be performed by a button operation.
