Description

  The present invention relates to a broadcast material processing apparatus for copying, for example, broadcast material data recorded by a video server provided in an active system of a duplex facility to a video server provided in a standby system.

  As is well known, in a broadcasting station, for example, broadcast material data such as a television broadcast or radio broadcast program, CM (commercial), text or data program is stored in a semiconductor memory, and the semiconductor memory is stored at an arbitrary timing. A video server that reproduces broadcast material data stored in the network is used.

Also, in the above broadcasting stations, it is common to have a working / standby duplex configuration for equipment failure countermeasures and maintenance, so that a video server is used for each of the working and standby systems. (For example, Patent Document 1).
JP-A-9-294243.

  By the way, in the above duplex configuration, an example is a migration recording method in which broadcast material data is recorded on the video server in the active system, and then the active broadcast material data is transferred and copied to the standby video server. Conceivable. In this migration recording method, it is necessary to confirm the quality of the broadcast material data copied to the standby video server.

  In such a case, the quality of the broadcast material data to be copied is confirmed by performing manual reproduction by the operator after copying, and performing re-copying and manual reproduction upon error. However, even if re-copying is used, the block used in the semiconductor memory of the video server does not change, so there is a high probability of an error again. Finally, the relevant block in the semiconductor memory is manually set to non-use and then re-copying is performed. This has to be done, which puts a huge amount of work on the operator.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a broadcast material processing apparatus that can automatically determine the quality of memory contents at a copy destination after material copying and thereby suppress a reproduction failure.

  In order to achieve the above object, a broadcast material processing apparatus according to the present invention includes a first information processing unit as an active system that reproduces encoded data of a broadcast material stored in a first storage medium, and the first information processing unit. The encoded data that is connected to one information processing unit and is reproduced from the first information processing unit is recorded on a second storage medium having a block structure, and the encoded data is reproduced from the second storage medium and A second information processing unit as a standby system that decodes and transmits the broadcast material signal and an abnormality detecting means for detecting an abnormality of the block of the second storage medium when the encoded data is recorded on the second storage medium Are provided.

  The abnormality detecting means automatically reproduces the encoded data recorded on the second storage medium, and detects an abnormality of the block of the second storage medium based on the decoded broadcast material signal. To do.

  According to this configuration, the encoded data recorded on the second storage medium is automatically reproduced and decoded into the original broadcast material signal, and the recorded content of the second storage medium is utilized using this broadcast material signal. PASS / FAIL is detected. In other words, the quality confirmation of the encoded data of the broadcast material copied to the standby second information processing unit is automatically performed without requiring manual operation.

  Therefore, it is possible to automatically determine the quality of the memory contents at the copy destination after the material copy, thereby suppressing a reproduction failure. On the other hand, for the operator (user), the labor required for confirming the quality of the encoded data of the broadcast material copied to the second information processing unit in the standby system can be greatly reduced, and the occurrence of check mistakes is prevented and accurate It is possible to check the quality of highly reliable broadcast materials.

  Furthermore, based on the detection result by the abnormality detection means, a retry request for reproducing the encoded data stored in the first storage medium is sent again to the first information processing unit, and the first request is sent to the first information processing unit. An abnormality handling means is provided for recording the encoded data reproduced from the information processing unit in a block of a second storage medium different from the block in which the encoded data is recorded before sending the retry request.

  According to this configuration, when an abnormality is detected in the block of the second storage medium, a retry request is sent to the first information processing unit, and the encoded data reproduced from the first information processing unit again. It is recorded in a second storage medium block different from the previous one. Accordingly, the probability of successful retry is increased, thereby preventing the occurrence of a reproduction failure due to the abnormality of the second storage medium.

  The abnormality handling means is characterized in that when the number of retry request transmissions exceeds a reference value, the user is notified as an alarm that the number of retry request transmissions exceeds the reference value.

  According to this configuration, when the second storage medium needs to be replaced, by notifying the operator of this abnormal state as an alarm, the operator can immediately know the occurrence of the abnormality in the second storage medium, As a result, it is possible to quickly take a countermeasure such as a recovery operation.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of a video material bank system as a broadcast material processing apparatus according to the present invention.

  In FIG. 1, reference numeral 11 denotes an active video recording / reproducing apparatus, and 12 denotes a standby video recording / reproducing apparatus. These video recording / reproducing apparatuses 11 and 12 are provided with semiconductor memories 111 and 121, respectively. Here, in the active system, the video material data as the broadcast material is recorded in the semiconductor memory 111 of the video recording / reproducing apparatus 11, and thereafter, in the semiconductor memory 111 according to the video material copy request from the operation terminal 13. It is assumed that a migration recording method is used in which the recorded video material data is transferred to the standby video recording / reproducing apparatus 12 and copied.

  An alarm device 14 is connected to the video recording / reproducing device 12.

  FIG. 2 is a block diagram showing the internal configuration of the video recording / playback apparatus 12. Here, in order to simplify the description, it is assumed that the input channel of the video recording / reproducing apparatus 12 is 4 channels and the output channel is 7 channels.

  An input unit 122, a control unit 123, and an output unit 124 are connected to the semiconductor memory 121. The input unit 122 captures 4-channel video material data and records it in an appropriate area of the memory 121 under the control of the control unit 123.

  The control unit 123 manages the four-channel video material data recorded in the memory 121, and in response to a reproduction instruction input, the output unit 124 performs the reproduction start address, the number of reproduction bytes, and the transmission bit rate ( Band).

  The output unit 124 reads the video material data recorded in the semiconductor memory 121 from the address specified by the control unit 123 by the specified number of bytes, decodes it to the original video material signal, and outputs it to the corresponding output channel. .

  By the way, in this embodiment, the control unit 123 includes an abnormality detection unit 1231 and a retry control unit 1232.

  The abnormality detection unit 1231 automatically reproduces the video material data recorded in the semiconductor memory 121 and checks whether or not the video material data is correctly written in the semiconductor memory 121 based on the video material signal decoded by the output unit 124.

  When the abnormality detection unit 1231 determines that the video material data is not correctly written in the semiconductor memory 121, the retry control unit 1232 uses the empty port (empty output channel) to the video recording / reproducing device 11. A memory block in which a retry request for reproducing the video material data stored in the semiconductor memory 111 is transmitted, and the video material data reproduced from the video recording / reproducing apparatus 11 in response to the retry request is recorded with the video material data before the retry request is transmitted. Recording is performed in a memory block of the semiconductor memory 121 different from (for example, 1 block 8 MByte).

Next, the processing operation in the above configuration will be described.
FIG. 3 is a flowchart showing a control processing procedure of the video recording / reproducing apparatus 12.
First, when copying video material data, a copy instruction is sent from the operation terminal 13 to the video recording / reproducing apparatuses 11 and 12. When there is a copy instruction from the operation terminal 13, the video recording / reproducing device 11 starts copying to the video recording / reproducing device 12.

  After completing the copy, the video recording / playback apparatus 12 proceeds from step ST3a to step ST3b and automatically plays back the video material data recorded in the semiconductor memory 121. Then, it is determined whether or not the video material data is correctly written in the semiconductor memory 121 by monitoring whether or not the video material signal decoded by the output unit 124 is correct (step ST3c). Note that although the video material data sent from the active system has been subjected to error correction by Reed-Solomon or the like, an error that cannot be corrected may occur. In this case, the control unit 123 of the video recording / reproducing apparatus 12 transmits a retry request to the active video recording / reproducing apparatus 11 via the empty port (step ST3d).

  On the other hand, the video recording / reproducing apparatus 11 starts re-copying to the video recording / reproducing apparatus 12 in response to the retry notification.

  The video recording / reproducing apparatus 12 receives the video material data sent from the video recording / reproducing apparatus 11 (step ST3e), and writes the received video material data using a memory block different from the previous one (step ST3f). This avoids a block failure peculiar to the copy destination semiconductor memory 121 and increases the probability of successful retry.

  Thereafter, the video recording / reproducing apparatus 12 performs automatic reproduction and ends the process if there is no error, and repeats the processes of steps ST3d to ST3f when there is an error.

  Note that the video recording / reproducing device 12 can generate an alarm to the alarm device 14 when the number of retries exceeds, for example, three times.

  As described above, in the above embodiment, the video recording / playback apparatus 12 automatically plays back video material data recorded in the semiconductor memory 121 and decodes it to the original video material signal by the output unit 124. Is used to detect the quality of the recorded contents of the semiconductor memory 121.

  Accordingly, the quality confirmation of the video material copied to the standby video recording / reproducing apparatus 12 is automatically performed without requiring manual operation, thereby suppressing the reproduction failure. On the other hand, for the operator (user), the labor required for checking the quality of the video material copied to the standby video recording / reproducing apparatus 12 can be greatly reduced, and further, the occurrence of check mistakes is prevented and the video is accurate and reliable. The quality of the material can be checked.

  In the above-described embodiment, when an abnormality is detected in the memory block of the semiconductor memory 121 in the video recording / playback apparatus 12, a retry request is sent to the active video recording / playback apparatus 11, and the video recording / playback apparatus again. 11 is recorded in a memory block of the semiconductor memory 121 different from the previous one. Therefore, the probability of successful retry is increased, thereby preventing the occurrence of a reproduction failure due to an abnormality of the semiconductor memory 121.

  Further, in the above embodiment, when the semiconductor memory 121 needs to be replaced, the alarm device 14 notifies the operator of this abnormal state as an alarm, so that the operator can immediately know the occurrence of the abnormality in the semiconductor memory 121. As a result, it is possible to quickly take a countermeasure such as a recovery operation.

  In the above embodiment, when there is no port for automatic reproduction, a preview port can be used to increase the priority of the preview, and the automatic reproduction can be performed during the preview free time. At this time, if there is a preview operation during automatic reproduction, the automatic reproduction is interrupted and the preview is executed. Automatic playback is performed after the preview is completed.

  In the above embodiment, the above function can also be used when an external hard disk type large-capacity video material server is connected and the material is automatically copied one day before the broadcast date.

  In addition, the system configuration, the type of material to be handled other than the video material, the control procedure when the abnormality occurs in the semiconductor memory, and the contents thereof can be variously modified and implemented without departing from the gist of the present invention.
