Abstract

<P>PROBLEM TO BE SOLVED: To stop recording operation if a reception becomes worse during the recording operation, and to supplement an unrecorded part thereafter with other data when data received by a digital broadcast receiver are recorded. <P>SOLUTION: A recording medium is provided where a digital broadcast is received and recorded, and a reception failure detector 30 detects the reception level of the broadcast being lower than specified to stop recording the received broadcast in such a case, and to restart the recording after the reception failure is removed. When the reception failure is detected, rebroadcasting of the received broadcast program is detected from received broadcast program data, and when rebroadcasting is available, the recording of the rebroadcast program is reserved. When the rebroadcasting is not available, the broadcast program data are transmitted to an in-home digital broadcast receiver 51 with a video recording function installed in home, and video recording is immediately started. When rebroadcasting recording is performed thereafter or when recording is carried out by the in-home equipment, their data are used to fill data at the destination of a video-recording deficient part, thereby obtaining complete video recording data. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a digital broadcast receiver with a recording function for receiving and recording a digital broadcast, and in particular, a received radio wave condition is deteriorated due to a change in a surrounding reception environment due to movement, such as a vehicle-mounted device, and recording of a received broadcast is appropriate. The present invention relates to a digital broadcast receiver that can perform supplementary editing using separately recorded data even when it is not performed.

  In recent years, CS digital broadcasting, BS digital broadcasting, and terrestrial digital broadcasting have become widespread. In particular, since terrestrial digital broadcasting can be satisfactorily received by a high-speed moving body such as a vehicle, it is suitable as a television receiver for vehicles and is expected to be widely spread as a vehicle-mounted device. In addition, digital broadcasting is not limited to television broadcasting, and digital audio broadcasting is also performed. Further, in recent years, a hard disk (HDD) drive has been mounted on a vehicle as an audio device in addition to a navigation device. There is an environment in which broadcasts can be received and recorded by onboard equipment and listened to as needed.

  In recent years, DVD record players that record and view video and music data on a DVD as home appliances have become widespread, and are equipped with a large capacity HDD, make a lot of recording reservations, and then need it. It is also widely practiced to edit and record things on DVDs. Such HDD-DVD recording devices are small and inexpensive, and it has been proposed to mount them on vehicles. In particular, since the vehicle is equipped with an HDD drive as described above, it can be used immediately with the current device configuration when used without a DVD recording function.

  On the other hand, in the conventional digital television receiver, when the radio wave reception state deteriorates due to rain or the like, a warning display indicating that the reception state has deteriorated is continued, and when the reception state becomes good, normal image output is again performed. Like to do. Further, in a receiver having a recording function, if the radio wave reception state is poor, a flickering screen with poor video quality is recorded, or a still image is continuously recorded. In particular, when such a digital television receiver is mounted on a vehicle as described above, the radio wave state changes greatly, so it is expected that this will occur frequently.

  For example, in the example shown in FIG. 6, when a digital broadcast receiver is mounted on a vehicle, the reception state of radio waves changes depending on the surrounding environment, and the reception level changes greatly. Below the decodable reception level that can be properly processed by the decoding unit occurs in the F1 portion between t1 and t2, the F2 portion between t3 and t4, and the F3 portion between t5 and t6. As a result, normal moving picture and sound part recording is performed in the R1, R2, R3, and R4 parts other than the above-mentioned period, but still pictures and silent parts are recorded in the F1, F2, and F3 parts. Will be performed.

In order to improve such a state, in Patent Document 1 below, the reception state of the radio wave is such that the reception state of the radio wave is poor, warning screens are displayed endlessly, and meaningless data is not continuously recorded. When it deteriorates more than a predetermined level, recording is not performed, and EPG data, which is an electronic program guide separately transmitted in digital broadcasting, is used to present an electronic program guide to the user, or related programs are displayed on a multi-display. It is proposed to perform processing such as displaying or recording the same program when the same program is being broadcast and receiving and recording the previous broadcast again when the radio wave reception is improved. ing.

And means.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram showing various functional units and their interrelationships in an example in which a digital broadcast receiver according to the present invention is applied to a vehicle-mounted digital broadcast receiver with a recording function, and is implemented in various modes. In this example, various functional units are provided so as to be able to. In addition, each function part in the figure can also be said to be a means for performing each function.

  The vehicle-mounted digital broadcast receiver 11 with a recording function shown in FIG. 1 has a ROM that stores predetermined software, a CPU that processes the software, and a system control unit 12 that includes a RAM and the like. By connecting each functional unit to the unit 12, a predetermined operation can be performed in advance.

  The digital broadcast radio wave received by the antenna 13 extracts the reception frequency component of the receiving station designated by the user using the remote controller or the like in the receiving channel selection unit 14, and demodulates the intermediate frequency signal obtained by performing frequency conversion on the extracted signal. To the unit 15. The demodulating unit 15 performs orthogonal demodulation processing and FFT demodulation processing on the input intermediate frequency signal to demodulate the interleaved transmission data, and further decodes the interleaving to return to the original data string. Output to. The error correction unit 16 performs error detection and correction processing on the input data, and outputs this to the decoding unit 17. The decoding unit 17 decodes and outputs the input multiplexed composite data into video data 18 and audio data 19, various data control signals, and information data 20 such as EPG data to be described later.

  The video decoding unit 21 decodes the video data separated by the decoding unit 17 to obtain a video signal 22, performs a separate image display process on the video signal 22, and displays the video on a monitor. Also, the audio decoding unit 23 decodes the audio data, outputs it as an audio signal 24, performs audio output processing separately, and outputs the audio from the speaker. The information data 20 is processed by the system control unit and used as various control signals or data.

  In the digital broadcast receiver 11 shown in FIG. 1, the reception state often changes due to surrounding buildings, trees, mountains, etc. as the vehicle moves at high speed, especially because it is mounted on a vehicle, and the level of the received signal decreases. The video may become a still image and the audio may be below a predetermined level that silences. In this way, the reception failure detection unit 30 detects that the reception signal has become a reception failure below a predetermined level and that the reception failure has been eliminated. Further, the reception data position detection unit 31 records a currently received program on a recording medium 38 to be described later, when the reception failure detection unit 30 detects such a reception failure, and The data position in the program when the reception failure is resolved is detected. This detected data is recorded in a recording defect portion storage unit 39 which will be described later.

  The EPG data capturing unit 32 captures EPG data, which is electronic program data included in the information data 20 and is updated every predetermined time. In the example of FIG. 1, this data can be used immediately. Are stored in the EPG data update storage unit 33 while being appropriately updated. As will be described later, the rebroadcast detection unit 34 searches for the rebroadcast of the program from the EPG data stored as described above and records it in the recording reservation unit 35 when reception failure occurs during program recording. Output.

  When the rebroadcast detection unit 34 detects that there is no rebroadcast in the current EPG data, the recording instruction EPG data output unit 42 is operated, and the recording instruction EPG data output unit 42 performs EPG data relating to the program currently being recorded. Is transmitted from the EPG data update storage unit 33 and transmitted as an operation signal of the home digital broadcast receiver 51 with a recording function installed in the user's home or the like from the communication unit 43 such as a cellular phone or the antenna 44. In the example shown in the figure, when there is a rebroadcast of a program that is currently poorly received, EPG data related to the program data is also sent to the recording instruction EPG data output unit 42 and recorded by a home digital broadcast receiving device. I make a reservation. In the embodiment shown in FIG. 1, an example is shown in which a digital broadcast is received and recorded, but the present invention can also be applied to a digital audio broadcast reception as described above, in which case FIG. The “function” related to “recording” is simply a function related to “recording” of data.

  As described above, the recording reservation unit 35 performs recording reservation when the rebroadcast detection unit 34 detects the presence of rebroadcast, and as a normal mode, an external instruction signal input unit for inputting an external instruction signal from a remote controller or the like. A recording reservation is made so as to record a predetermined program in accordance with 36 instructions. In that case, the data in the EPG data update storage unit 33 can be used. In the recording data output unit 37, in the illustrated embodiment, video data, audio data, and various data such as character data, which are taken in via the system control unit 12, are converted into an HDD, a DVD recorder, or a DVD with HDD. The data is output to a recording / recording medium 38 such as a recorder. In this case, a predetermined program can be recorded in accordance with an instruction from the recording reservation unit 35 in addition to an instruction signal input from the user. The recording defect portion storage unit 39 records the data position of the portion where the recording is lost when the program being recorded is poorly received in the middle as described above.

  In the recording editing unit 41, when the recorded program in which the defect has occurred is rebroadcast and recorded on the recording recording medium 38, or as will be described later, the defective part is recorded by the home digital broadcast receiver 51 with a recording function. When this can be taken in from the external data take-in unit 40, the recorded data is the same as the data properly recorded by embedding the data in the previously recorded data with the recording missing part as will be described later. Edit so that

  On the other hand, in the home digital broadcast receiver 51 with a recording function installed in the home, the vehicle-mounted digital broadcast reception with the current recording function transmitted from the communication unit 43 such as a cellular phone as described above by the communication unit 53 is received. The EPG data relating to the program being recorded by the device 51 is received via the antenna 52 and is output to the recording instruction EPG data input unit 54. The recording instruction EPG data input unit 54 outputs the input EPG data to the digital broadcast receiving unit 56, and immediately starts receiving and recording the program.

  Further, as described above, when EPG data of a rebroadcast program detected by the rebroadcast detection unit 34 is sent from the recording instruction EPG data output unit 42, this is output to the recording reservation unit 57 to make a recording reservation. . The recording data output unit 58 receives the digital broadcast receiving unit 56 and outputs the recording data subjected to various processes in the same manner as described above to the recording recording medium 59. At that time, in accordance with an instruction from the recording reservation unit 57, a predetermined program among the programs received by the digital broadcast receiving unit 56 is output to the recording recording medium 59. The digital broadcast receiving unit 56 is also activated in response to an instruction from the recording reservation unit 57. The recording data external output unit 60 records the recording data of the recording recording medium 59 recorded as described above on various recording media such as a DVD, a memory, and a portable HDD, and receives the vehicle-mounted digital broadcast with the recording function. It is connected to or inserted in the external data fetching unit 40 of the device 11 so that it can be used directly, or can be recorded on the recording recording medium 38 via the recording editing unit 41. Thereafter, the recording editing unit 41 can perform predetermined editing on the data recorded on the recording recording medium 38.

  In the digital broadcast receiver composed of the functional blocks as described above, the recording is performed while receiving the digital broadcast, and the operation of performing supplementary editing in various manners on the recording defect portion caused by stopping the recording due to the decrease in the reception level is as follows. For example, it can operate | move sequentially by the operation | movement flow shown in FIG.2 and FIG.3. These operations will be described below with reference to the functional block diagram of FIG. 1 and the recording editing operation explanatory diagrams of FIG. 4 and FIG.

  In the digital broadcast reception recording process shown in FIG. 2, the digital broadcast is first received (step S1), and the program recording operation designated by the user is performed (step S2). In this embodiment, EPG data is captured during digital broadcast reception, and is updated and recorded (step S3). This operation is performed by the EPG data capturing unit 32 in FIG. 1 capturing EPG data included in the information data 20 separated from the received data by the decoding unit 17 and recording it in the EPG data update storage unit 33.

  During the digital broadcast reception, it is determined whether or not the broadcast reception state is below a predetermined level (step S4). This determination can be detected by the reception failure detection unit 30 in FIG. 1 based on the received electric field strength, the number of error correction processes performed by the error correction unit 16, or the like. If it is determined that the broadcast reception state is not lower than the predetermined level, the process proceeds to step S13, where it is determined whether or not the recording is to be ended. If not, the process returns to step S2 to repeat the recording operation and the subsequent operations. When it is determined in step S13 that the recording is to be ended, the process proceeds to step S16 and the recording operation is ended. In the course of this process, the broadcast reception state never falls below a predetermined level, so that appropriate recording has been performed, and the process of the present invention is not performed.

  When it is determined in step S4 that the broadcast reception state has become a predetermined level or less, recording is stopped (step S5). Next, the data position of the recording stop program is recorded (step S6). This operation can be performed by, for example, recording time data at which recording is stopped in the time data string in the data structure of the entire program, in the recording defect portion storage unit 39, for the data portion that is no longer recorded. Thereby, for example, when recording is not performed due to a decrease in broadcast reception level during recording of a drama, time data from the start of the drama is recorded.

  Next, EPG data of the program being recorded is taken in (step S7), and a rebroadcast of the program currently being recorded is searched from the EPG. This is because the rebroadcast detection unit 34 in FIG. 1 re-broadcasts the currently broadcast program in the EPG data for a predetermined period such as one week recorded in the EPG data update storage unit 33. This is done by searching for whether or not. Here, when it is detected that a rebroadcast exists, the rebroadcast is reserved for recording (step S10).

  In the example shown in FIG. 2, when it is determined in step S9 that there is no rebroadcast, the EPG data of the program whose recording has been stopped while the broadcast is being received is sent to the home digital broadcast receiver 51 with a recording function using a mobile phone. To instruct recording (step S14).

  In the home digital broadcast receiver 51 with a recording function, this is input by the recording instruction EPG data input unit 54, the digital broadcast receiving unit 56 is operated, and recording is performed on the recording recording medium 59 from the recording data output unit 58. As a result, even if there are some unreceivable parts in the part not recorded by the vehicle-mounted digital broadcast receiver 11 with a recording function, stable recording is performed thereafter by the home digital broadcast receiver. .

  After re-broadcasting is scheduled for recording in step S10, and after EPG data is transmitted to the home digital broadcasting receiver with a recording function by a mobile phone or the like in step S14 and a recording instruction is given, the reception level becomes higher than a predetermined level. It is determined whether or not it has become (step S11). Here, when it is determined that the reception level has not yet exceeded the predetermined level, it is determined whether or not the recording is to be ended. If the recording level is not yet ended by a timer or the like, or if no end instruction is given by the user, Returning to step S11, the recording stop state is continued until the reception level becomes a predetermined level or higher. When the recording is ended by a timer or the like in the process, the recording operation is ended (step S16).

  If it is determined in step S11 that the reception level has become equal to or higher than the predetermined level, then recording is resumed, and the data position at which recording is resumed is recorded (step S15). This recording is performed by performing the same process as in step S6. Thereafter, the process returns to step S2 to perform the recording operation, and thereafter the operation is repeated. In this way, the recording missing portion storage unit 39 can record the start portion and the end portion of the recording impossible portion as described above.

  As a result of such recording processing by the digital broadcast receiver, improper recording is continuously performed when the reception level falls below a predetermined level, so that recording is stopped, and when there is a rebroadcast of the program It is possible to perform an operation of making a recording reservation and recording the broadcast currently being received by the home device when there is no rebroadcast, and continuing the recording when the reception level returns to a predetermined level or higher.

  On the other hand, in the present invention, when a recording defect portion exists due to the recording being stopped in the middle as described above, the recording defect portion is rebroadcast received recording data or the broadcast recorded by the home device. However, such a recording deficient portion supplementary editing process can be operated in sequence according to the operation flow shown in FIG. 3, for example. In the example of FIG. 3, first, other recording data for supplementing the recording defect part is taken in (step S21). This is performed by receiving the rebroadcast as described above and specifying the data of the same program recorded on the recording / recording medium 38 in the recording / recording medium, or recording directly on the recording / recording medium 59 of the home device. The recorded DVD or the DVD recorded on the HDD is re-recorded on the DVD player of the vehicle-mounted device, the data recorded on the home device is recorded on the portable HDD, and this is recorded on the vehicle-mounted digital broadcast receiver. This can be done by connecting to the external data fetching unit 40 and making the recording editing unit 41 editable. Note that when the program is recorded without loss by rebroadcast recording, all of the previously recorded data with loss may be deleted.

  Next, the recording defect part data is read from the recording defect part storage unit 39 of FIG. 1 (step S22). After that, the recording data for defect replacement is extracted for each recording defect part (step S23). Next, processing is performed to insert the recording data for defect replacement extracted in this way into a predetermined defect portion of the recording data including the recording defect portion (step S24). After that, if necessary, the missing replenishment recording data is deleted (step S25).

  These operations are performed, for example, as shown in FIG. That is, in the example shown in FIG. 4 (a), due to fluctuations in the reception level as shown in FIG. 6, the first recording defect portion F1 at the recording resumption time t2 at the recording stop start time t1 when recording one program, As a result of the presence of the second recording defect portion F2 at the recording resumption time t4 at the recording stop start time t3 and the third recording defect portion F3 at the recording resumption time t6 at the recording stop start time t5, the recording data is first in one program. The recording portion R1, the second recording portion R2, the third recording portion R3, and the fourth recording portion R4 are recorded data that continuously exist as shown in FIG. The data time in the recording defect portion between these recording portions is recorded in the recording defect portion storage unit 39 in FIG. In FIG. 6B, in the recording defect periods F1, F2, and F3 shown in the last part of all the recording data, useless recording of the recording recording medium 38 in FIG. 1 is not performed by stopping the recording. Finally, the recording data is as shown in FIG.

  When such re-broadcast recording data exists on the same recording / recording medium 38 as described above, the re-broadcast recording data is automatically detected, or according to the re-broadcast recording search result of the user. Then, rebroadcast recording data as shown in FIG. 4D is detected. In the rebroadcast recording data, there may be a recording defect part as in the first recording data. In the example shown in the figure, the fourth recording defect part F4 at the recording resumption time t8 at the recording stop start time t7 and the recording are recorded. As a result of the presence of the fifth recording defect portion F5 at the recording restart time t10 at the stop start time t9, the recording data in the same program is recorded data in which the fifth recording portion R5, the sixth recording portion R6, and the seventh recording portion R8 are continuous. can get.

  For example, in terrestrial digital broadcasting, even if it is received by a vehicle moving at high speed, it depends on the performance of the receiver, but in many cases it is stable and a short-time recording defect occurs. It is estimated that there is almost no overlap between the recording defect portion generated in step 1 and the recording defect portion generated during rebroadcast recording. If a recording defect part overlaps in both recording data, a re-broadcast search can be performed again at that time, and the same defect supplement processing can be performed.

  When the rebroadcast recording data as shown in FIG. 4D is obtained, the recording defect portion supplement data extraction processing as shown in FIG. 4E is performed. This diagram is a conceptual diagram of the processing, and is actually performed by simply extracting and copying data. As shown in FIG. 4E, in the recording defect portion supplement data by rebroadcast, the first recording defect supplement data H1 between times S1 and S2 corresponding to the first recording defect portion F1 in FIG. The second recording defect supplement data H2 between the times S3 and S4 corresponding to the second recording defect portion F2 and the third recording defect supplement data H3 corresponding to the third recording defect portion F3 can be cut out.

  FIG. 4F shows the recording defect supplement data extracted in this manner. The recording defect supplement data is inserted into the corresponding missing portion of the recording data with the defect as shown in FIG. 6C, and the insertion process is performed as shown in FIG. As a result, complete recorded data with a missing recording is obtained.

  On the other hand, when recording data supplemented by home appliances as described above is used as recording supplementary data, for example, by performing processing as shown in FIG. 5, data supplemented with missing portions of recording can be obtained. That is, in the example shown in FIG. 5, similarly to FIGS. 4 (a) to (c), the recorded data with a deficiency as shown in (c) is obtained by the processing of FIGS. 5 (a) to (c). As shown in FIG. 4D, the recording is started from the first recording stop start time t1 as a home device recording data, and as a general rule, a recording deficient portion occurs due to the home digital broadcast receiver. Stable recording data of the recording portion R8 without the image can be obtained.

  When the recorded part data 8 is captured from the external data capturing unit 40 of FIG. 1, the recording editing unit 41 uses a series of time data of the program from the recorded part R8 as shown in FIG. Using the time from the start time of the program, the first recording defect supplement data H1, the second recording defect supplement data H2, and the third recording supplement data H3 are extracted in the same manner as the processing shown in FIG. Then, three pieces of recording defect supplement data as shown in FIG. Thereafter, in the same manner as in the process shown in FIG. 4, a recording defect as shown in FIG. 4H is performed by performing an insertion process on the corresponding missing part of the recorded data with a defect as shown in FIG. Complete replenished recording data can be obtained.

  In the above-described embodiment, an example is shown in which the recording defect portion in the previous recording data having the recording defect portion is supplemented with the corresponding rebroadcast recording data. When the data is only missing, it is possible to obtain completed program recording data by supplementing the portion with data corresponding to the previous recording. Similarly, data recorded by a home device can be used as main data, and program recording data completed by supplementing data recorded by a vehicle-mounted device.

  The present invention can be similarly implemented by performing a recording process in place of the recording process in a digital broadcast audio receiver in addition to the digital broadcast television receiver as in the illustrated embodiment. In the above-described embodiment, the on-vehicle equipment with relatively large fluctuations in the reception level has been described. However, for example, in satellite digital broadcasting, the reception level may be lowered during rainfall or stormy weather. When the invention is applied and recording is stopped when the reception level is lowered at that time, the present invention can be used by performing supplementary editing processing on the portion in the same manner as described above by receiving the rebroadcast.
