Description

  The present invention relates to a receiver evaluation apparatus, a receiver evaluation method, and a program for evaluating a receiver that receives a digital broadcast.

  Conventionally, when developing a receiver for receiving a digital broadcast, an evaluation test is performed to confirm what kind of malfunction occurs when the operation is performed.

  For example, as a technique for detecting a defect, Patent Document 1 discloses a technique in which an information processing device determines whether or not a data broadcast can be received without error by operating a receiver with a remote controller. Has been.

  However, the technique disclosed in Patent Document 1 is intended to detect a malfunction of the receiver and is not intended to reproduce the malfunction. Therefore, in order to reproduce and repair the malfunction of the receiver, the evaluator and the developer need to perform the following processing.

  When the evaluator operates the receiver with the remote controller and visually confirms that a defect has occurred, the evaluator reports the contents of the defect and the operation procedure at that time to the developer in writing or in words. In addition, the evaluation person collects an operation log at the time of occurrence of a failure from the receiver and notifies the development person.

The developer in charge reads or listens to the report from the evaluator, confirms the operation log, and operates the receiver with the remote control to reproduce the problem and perform debugging. In addition, the developer in charge operates the receiver with the remote controller even in the operation check work after the defect correction.

However, in the above-described conventional receiver evaluation test, both the evaluation staff and the development staff are burdened as follows.
1. The burden on the evaluator and the evaluator need to always store the operation procedure during the evaluation work.

However, since human memory and attention are limited, it is difficult to always memorize operation procedures. Further, it is difficult for a human to memorize and record the operation content and timing at the time of occurrence of a failure strictly.
・ If the evaluator detects a problem that depends on the timing of the operation, the evaluator verifies the operation procedure that can accurately reproduce the timing, and then writes a text to help the developer understand the operation procedure. Or it must be expressed in words.

However, it takes time to verify such an operation procedure. In addition, since there is a limit to expressing the operation procedure in sentences or words, it is difficult for the developer to understand the operation procedure accurately.
-If software (here, the receiver firmware) is operated while collecting operation logs from the receiver, the operation of the receiver becomes slow due to the overhead of the operation log output function. For this reason, the evaluator first tried to detect a failure in the normal mode without collecting the operation log, and when a failure was detected, change the setting to the operation log output mode to collect the operation log again. Therefore, it is necessary to reproduce the problem anew.

However, since it is necessary to reproduce the defect again in the operation log output mode after detecting the defect in the normal mode, it is troublesome twice. Also, it is conceivable that the problem is not reproduced even if the operation is performed at the same timing in the normal mode and the operation log output mode.
2. Depending on the sentences or words reported by the evaluation staff, it may be difficult for the development staff to accurately understand and reproduce what kind of trouble has occurred.
・ Developers need to reproduce defects accurately based on reports from evaluation personnel, but it may be difficult to perform accurate reproduction operations depending on the manpower.
・ Developers need to wait until re-broadcasting of the program or the next broadcast in order to correct a problem when the program has already been broadcast. It takes time to prepare.
・ The developer in charge must confirm that the defect does not reproduce in the operation check work after correcting the defect after performing the operation according to the operation procedure to reproduce the defect. It may be difficult to perform an accurate reproduction operation.
・ In order to confirm that the defect does not reproduce, it is certain that the developer in charge confirms it visually against the operation before correcting the defect, but for this purpose, a plurality of receivers are prepared. Therefore, it is necessary to perform the reproduction operation simultaneously and accurately.

  However, preparing a plurality of receivers for each developer is expensive and requires a lot of space for installation. In addition, depending on the manpower, it may be difficult to visually confirm a plurality of receivers while operating them simultaneously.

  As described above, in the receiver evaluation test, it is possible to accurately record what kind of trouble occurred and what kind of trouble occurred without imposing a burden on the evaluator and developer. It is an important issue to be able to reproduce it.

  Therefore, the purpose of the present invention is to accurately record what kind of trouble has occurred in what operation without imposing a burden on the evaluator and developer, and accurately reproduce the trouble. An object of the present invention is to provide a receiver evaluation device, a receiver evaluation method, and a program.

In order to achieve the above object, the receiver evaluation apparatus of the present invention provides:
A receiver evaluation device for evaluating a receiver that receives a digital broadcast,
A broadcast stream data processing unit that records broadcast stream data of the same broadcast wave as the broadcast wave of digital broadcast received by the receiver in a recording unit;
The operation data representing the operation content of the receiver, which is output from the operation means for the receiver to the receiver, is input, and the input operation data is associated with time data included in the broadcast stream data. An operation data processing unit for recording in the recording unit;
A video / audio data processing unit that inputs video / audio data output during reception of the digital broadcast from the receiver, and records the input video / audio data in the recording unit in association with time data included in the broadcast stream data; It is characterized by having.

  According to this configuration, while recording operation data for the receiver, the broadcast stream data and the video / audio data output from the receiver are simultaneously recorded, and the operation data and the video / audio data are included in the broadcast stream data. It is recorded in association with time data.

  Therefore, it is possible to accurately record what kind of trouble has occurred in the receiver when the receiver is operated without imposing a burden on the evaluator. This avoids misrecognition between the evaluator and development staff regarding the content of the defect and the operation procedure at that time, thus facilitating the reproduction of the defect and reducing the burden on the developer. The

The broadcast stream data processing unit reproduces the broadcast stream data recorded in the recording unit, and outputs the reproduced broadcast stream data to the receiver.
The operation data processing unit synchronizes operation data recorded in the recording unit with broadcast stream data reproduced by the broadcast stream data processing unit, using time data recorded in association with the operation data. It is good also as reproducing | regenerating while taking and outputting the reproduced operation data to the said receiver.

  According to this configuration, the broadcast stream data and the operation data are simultaneously played back and output to the receiver, so that the malfunction can be accurately and repeatedly reproduced at the output receiver. The accuracy and speed of analysis can be improved.

  In addition, the video / audio data processing unit uses the time data recorded in association with the video / audio data for the video / audio data recorded in the recording unit to be reproduced by the broadcast stream data processing unit. Playback may be performed while synchronizing with the stream data.

  According to this configuration, when the operation procedure at the time of occurrence of a failure is accurately reproduced in the operation check work after the completion of the failure correction of the receiver, the video and audio reproduced by the receiver evaluation device remains in a state where the failure has occurred. It is. Thereby, it can be confirmed by visual comparison with the reproduction result of the receiver evaluation device that the defect is not reproduced in the receiver, and therefore the operation check operation after the defect correction can be facilitated.

  According to the present invention configured as described above, it is possible to accurately record what kind of trouble has occurred in the receiver when the receiver is operated without imposing a burden on the evaluator. The effect is obtained. This avoids misrecognition between the evaluator and the developer in terms of the content of the defect and the operation procedure at that time, making it easier to reproduce the defect and reducing the burden on the developer. You can also get the effect.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  Referring to FIG. 1, a receiver evaluation apparatus 10 according to the present embodiment is an evaluation apparatus for evaluating a receiver 20 that receives a digital broadcast.

  The receiver evaluation device 10 can receive the operation data when the operation data representing the operation content of the receiver 20 is transmitted from the remote controller 30 for the receiver 20 to the receiver 20. . Furthermore, the receiver evaluation device 10 can also transmit operation data to the receiver 20.

  Further, the receiver evaluation apparatus 10 shares the antenna 40 with the receiver 20 and receives the same broadcast wave received by the receiver 20 from the antenna 40.

  In addition, a display device 50 is connected to the receiver evaluation apparatus 10, and a display device 60 is connected to the receiver 20.

  Here, an internal configuration of the receiver evaluation apparatus 10 will be described.

  The receiver evaluation apparatus 10 includes a recording unit 11, a broadcast stream data processing unit 12, a video / audio data processing unit 13, a remote control transmission unit 14, a remote control reception unit 15, and an operation data processing unit 16.

  Broadcast stream data is recorded in the broadcast stream data recording unit 11-1.

  In the video / audio / time data recording unit 11-2, video / audio data output from the receiver 20 during reception of the digital broadcast is recorded in association with the time data.

  The operation / time data recording unit 11-3 records operation data received from the remote controller 30 in association with time data.

  The broadcast stream data processing unit 12 inputs the same broadcast wave as the digital broadcast broadcast wave received by the receiver 20 from the antenna 40, converts the input broadcast wave into broadcast stream data, and broadcast stream data recording unit 11 Record -1. The broadcast stream data processing unit 12 reproduces the broadcast stream data recorded in the broadcast stream data recording unit 11-1, converts the reproduced broadcast stream data into a broadcast wave, and outputs the broadcast wave data to the receiver 20.

  In the present embodiment, it is assumed that the receiver 20 does not have a function of reading broadcast stream data, and the broadcast stream data processing unit 12 is described as performing the above operation. Is provided with a function for reading broadcast stream data, the broadcast stream data processing unit 12 directly inputs the broadcast stream data and reproduces the broadcast stream data recorded in the broadcast stream data recording unit 11-1. Then, it is output directly to the receiver 20 without being converted into a broadcast wave.

  In addition, the broadcast stream data processing unit 12 extracts time data stored in packets constituting the broadcast stream data, and outputs the extracted time data to the video / audio data processing unit 13 and the operation data processing unit 16. .

  For example, when the broadcast stream data is in the MPEG1, MPEG2-PS or MPEG2-TS format, the PS packet or TS packet constituting the broadcast stream data is counted up at a certain frequency in an area called PCR (Program Clock Reference). A count value called an STC (System Time Clock) value is stored. In this case, the broadcast stream data processing unit 12 extracts an STC value as time data. The STC value is usually used to perform synchronized playback (AV synchronization) of video and audio.

  The video / audio data processing unit 13 inputs (captures) the video / audio data output from the receiver 20, and records the input video / audio data in the video / audio / time data recording unit 11-2 in association with the time data. The video / audio data processing unit 13 synchronizes the video / audio data recorded in the video / audio / time data recording unit 11-2 with the broadcast stream data using the time data recorded in association with the video / audio data. The reproduced video / audio data is output to the display device 50.

  When the operation data from the remote controller 30 is received by the remote control receiver 15, the operation data processor 16 inputs the operation data, associates the input operation data with the time data, and the operation / time data recording unit 11-3. To record.

(2) Next, the broadcast stream data processing unit 12 reproduces the broadcast stream data, converts the reproduced broadcast stream data into a broadcast wave, and outputs the broadcast wave to the receiver 20. The receiver 20 outputs a video / audio to the display device 60 by performing a predetermined video / audio output process on the broadcast wave output from the broadcast stream data processing unit 12.
(3) Further, the broadcast stream data processing unit 12 extracts time data from the broadcast stream data being reproduced, and outputs the extracted time data to the video / audio data processing unit 13 and the operation data processing unit 16.
(4) The video / audio data processing unit 13 plays back the video / audio data included in the video / audio / time data while synchronizing with the broadcast stream data using the time data included in the video / audio / time data. The video / audio data is output to the display device 50. Specifically, the video / audio data processing unit 13 performs reproduction while synchronizing the time data output from the broadcast stream data processing unit 12 and the time data included in the video / audio data / time data. .
(5) The operation data processing unit 16 reproduces the operation data included in the operation / time data while synchronizing with the broadcast stream data using the time data included in the operation / time data.

The work speed can be improved.

  In addition, in this embodiment, since broadcast stream data is recorded during the evaluation work, it is no longer necessary for the development staff to wait for rebroadcasting of the program in which a problem occurred during broadcast or the next broadcast. Since debugging work can be immediately performed, debugging efficiency can be improved.

  In the present embodiment, broadcast stream data, video / audio data, and operation data recorded during the evaluation work can be transmitted to a remote location via a network. Even if a problem occurs during the broadcast of a program that is broadcast only on a limited basis, the problem can be reproduced and debugged without going to the site.

  Further, in the present embodiment, when performing the operation check work after the defect correction of the receiver 20 is completed, the video / audio output process is performed by the receiver 20 according to the operation data received from the remote control transmission unit 14, and the display device 60. To confirm that the receiver 20 does not reproduce the problem by visually comparing the video and audio output to the video and the video and audio data reproduced by the video and audio data processing unit 13 and output to the display device 50. Therefore, it is possible to facilitate the operation check work after correcting the defect and improve the debugging accuracy. Further, since it is not necessary to arrange a plurality of receivers 20 for the operation check work after correcting the defect, the cost and the space at the development site do not increase.

  In this embodiment, the receiver evaluation device 10 is configured to input a broadcast wave and convert it into broadcast stream data inside the device. However, as described above, depending on the configuration of the receiver 20, the broadcast stream A configuration in which data is directly input may be used.
