Description

Program updating method and device, electronic equipment and storage medium
Technical Field
The embodiment of the invention relates to the technical field of digital televisions, in particular to a program updating method and device, electronic equipment and a storage medium.
Background
In the field of digital televisions, program searching is a precondition for watching television programs, and in order to increase the speed of program searching, digital televisions have been developed to issue a program update identifier, an NIT (Network Information Table), an SDT (System Device Table) Actual Table, an SDT Other Table, and the like through a unidirectional TS (Transport Stream) code Stream (such as a TS code Stream transmitted based on a coaxial cable). The NIT is used for describing the number of the current frequency points, the number of programs corresponding to each frequency point, the service Id of each program, the program type and other information. The SDT Actual table is used for describing information such as program names, program types and the like of all programs of the current frequency point. The SDT Other table is used to describe the program names and corresponding program types of all frequency points except the current frequency point. Each bin corresponds to an SDT Other table. According to the table data, whether the current digital television program has program updating or not is monitored under any live program frequency point, and all programs can be received and stored under a single frequency point, so that the channel searching speed and the user experience of a user are improved.
However, when the program update is performed, a situation that the program reception is not completely performed may be encountered, that is, all the programs described in the NIT table are not completely downloaded. To address this problem, two general approaches are used, one is: the program update operation continues to receive program data until all programs described in the NIT table are downloaded. The other is as follows: before the program updating mark sent by the TS code stream is not changed, the program updating operation is executed only once no matter whether the program is completely received or not,
therefore, the first method undoubtedly brings great consumption to the system resources of the set-top box; the second method cannot guarantee that all programs described in the NIT table are downloaded, and thus, the channel searching speed and user experience of the user cannot be guaranteed.

Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a flowchart illustrating a program updating method according to an embodiment of the present invention. The program updating method disclosed in this embodiment is suitable for the case of performing program updating based on a TS stream transmitted by a coaxial cable, and may be executed by a program updating apparatus, where the apparatus may be implemented by software and/or hardware, and is generally integrated in a terminal, such as a digital television or a set-top box. Referring specifically to fig. 1, the method comprises the steps of:
step 110, periodically detecting the real-time program update identifier and the existing program update identifier stored in the system.
The real-time program updating identification is obtained by analyzing the TS code stream and is used for representing the version of the program released by a program operator in real time; the existing program update identifier is used to indicate the version of the program for which the current television system has completed updating. The programs specifically refer to channel programs, for example, including central satellite television, Zhejiang satellite television, Hunan satellite television, and the like, and do not refer to programs such as TV shows, movies, or art programs. Programs such as drama, movie or anarchic are generally referred to as events in the digital television field, and the programs are specifically referred to as channel programs such as central satellite television, Zhejiang satellite television, Hunan satellite television and the like.
And step 120, when the real-time program updating identification is determined to be inconsistent with the existing program updating identification, executing a program updating operation.
Supposing that the update identifier of the real-time program is 3 by analyzing the TS code stream, the current frequency points have 150 programs, and the update identifier of the existing program stored in the system is 2, because the update identifier of the real-time program is not consistent with the update identifier of the existing program stored in the system, or because the update identifier of the real-time program is higher than the version of the update identifier of the existing program stored in the system, it indicates that the program operator has updated the existing program, and therefore the existing program of the television system needs to be updated in the background, and the 150 programs are all received and downloaded, so as to improve the channel searching efficiency of the user.
Step 130, after executing the program updating operation for the preset duration, executing the detection completion operation to determine whether all the current preset program data are received through the program updating operation.
The preset program data specifically refers to all program data under all current frequency points obtained by analyzing the TS code stream. Specifically, the purpose of performing the detection completion operation is to determine whether all the 150 programs are received and downloaded by performing the program updating operation once, if so, modify the existing program updating identifier of the system to the real-time program updating identifier, otherwise, continue to perform step 150.
Step 140, if the current preset program data is completely received through the program updating operation, modifying the existing program updating identifier into the real-time program updating identifier.
And 150, if the current preset program data are not completely received through the program updating operation, judging whether the current frequency point belongs to a live broadcast frequency point.
The current frequency point specifically refers to a frequency point where a program currently watched by a user is located, for example, if the user is currently watching the Zhejiang satellite television, the current frequency point refers to a frequency point where the Zhejiang satellite television is located. If the user is watching the on-demand program at present, namely watching the program from a third-party resource platform, for example, the program passing through the Yoku on-demand, the frequency point at the moment does not belong to the live frequency point, when the user is confirmed to watch the on-demand program, the current program updating operation is finished, namely, the program is stopped to be continuously downloaded so as to reduce the system consumption, but the existing program updating identification is not changed, the program updating operation of the next period is waited to continuously update the program, namely, the next detection that the real-time program updating identification and the existing program updating identification stored by the system are the period is waited. The period can be set to 10 seconds, and can also be set according to the actual situation, and is usually set before the digital television leaves the factory, and the user does not need to perform related operations. The real-time program updating identification is compared with the existing program updating identification stored in the system once every 10 seconds, and when the real-time program updating identification and the existing program updating identification are inconsistent, the program updating operation is triggered, instead of continuously receiving the programs when the current preset program data are not completely received, so that the system is greatly consumed.
And step 160, if the current frequency point does not belong to the live broadcast frequency point, waiting for the next period to continue to execute the program updating operation.
In the program updating method provided by this embodiment, a real-time program updating identifier and an existing program updating identifier stored in a system are periodically detected; when the real-time program updating identification is determined to be inconsistent with the existing program updating identification, starting to execute a program updating operation; if all the preset program data are not received in one updating operation, different measures are taken according to whether the current frequency point is a live frequency point, if the current frequency point does not belong to the live frequency point, the next period is waited to continue executing the technical means of the program updating operation, when a user switches from the non-live frequency point to the live frequency point, the program updating operation can be continued, so that all the preset program data are received as far as possible, and the system consumption is reduced.
Example two
Fig. 2 is a flowchart illustrating a program updating method according to a second embodiment of the present invention. On the basis of the above embodiment, the present embodiment is further optimized by adding steps 270 to 290, and specifically referring to fig. 2, the method includes the following steps:
step 210, periodically detecting the real-time program update identifier and the existing program update identifier stored in the system.
And step 220, when the real-time program updating identification is determined to be inconsistent with the existing program updating identification, executing a program updating operation.
Step 230, after executing the program updating operation for the preset duration, executing the detection completion operation to determine whether all the current preset program data are received through the program updating operation.
Step 240, if the current preset program data is completely received through the program updating operation, modifying the existing program updating identifier into the real-time program updating identifier.
And step 250, if the current preset program data is not completely received through the program updating operation, judging whether the current frequency point belongs to a live broadcast frequency point.
And step 260, if the current frequency point does not belong to the live broadcast frequency point, waiting for the next period to continuously execute the program updating operation.
And 270, if the current frequency point belongs to the live broadcast frequency point, judging whether the execution times of the detection operation reaches a threshold value.
Step 280, if the number of execution times of the detection operation is up to the threshold, modifying the existing program update identifier into the real-time program update identifier, and simultaneously, returning the number of execution times of the detection operation to zero, and marking the non-received preset program according to a preset format.
The threshold may be set to 5 or other values, and is typically set before the digital tv leaves the factory. By setting the threshold, it is possible to prevent an endless background program update operation due to an objective cause other than the user operation. If all the preset program data are not received when the number of execution times of the detection operation is up to the threshold, it may be that the signal of the user end has a problem, for example, the signal quality is poor, or the TS code stream description of the front end is incorrect, for example, the number of the frequency point information described in the NIT table is greater than the sum of the number of the frequency point information of the SDT Actual table and the SDT Other table.
Wherein the preset format comprises: and at least one of frequency point frequency information of the program, current network identification information, current transport stream TS identification and service ID. The current network identification information specifically refers to a network identification of the user side, and is mainly used for identifying a city where the user is located. The preset programs which are not received are marked through the preset format, so that engineering personnel can conveniently and quickly locate the reasons of the problems, and the problems can be efficiently solved.
Step 290, if the number of times of executing the detection operation is not reached to the threshold, waiting for the next period to continue executing the program updating operation, and increasing the number of times of executing the detection operation by one.
In the program updating method provided by this embodiment, if all preset program data are not completely received in one updating operation, different measures are taken according to whether the current frequency point is a live frequency point, if the current frequency point belongs to the live frequency point and whether the execution frequency of the detection operation is up to a threshold, the existing program updating identifier is modified into the real-time program updating identifier, and meanwhile, the execution frequency of the detection operation is set to zero, and the preset program that is not received is marked according to the preset format, so that the endless background program updating operation caused by non-user operation objective reasons is effectively avoided while the preset program data are completely received as much as possible, and the system consumption is reduced.
