Description

TECHNICAL FIELD

[0001] The present application relates to the field of electronic technology, and in particular to a program search method, system and electronic device. BACKGROUND

[0002] A set top box (STB) is a device that connects a television to external signal sources. It converts compressed digital information into television content and displays it on a television. The signal can come from a cable, satellite dish, broadband network, or terrestrial broadcast. In addition to the images and sound that analog television can provide, the STB can receive digital content, including electronic program guides, Internet web pages, subtitles, and so on. This enables users to watch digital television programs on existing television sets and to engage in interactive digital entertainment, education, and commercial activities through a network.

[0003] There are many satellite frequencies in modern times, and it takes a long time to search all the frequencies. In the actual signals transmitted by existing satellites, the transmission density of each data table is different, and the interval of some satellite SDT tables is greater than 6 seconds. This means that the software of the STB needs to wait for a maximum of 6 seconds to determine whether a frequency has Service Description Table (SDT) information. Due to the above reasons, the time for the STB to search for satellites is very long, and it may take tens of minutes. SUMMARY

[0039] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings. The specific operation methods in the method embodiments can also be applied to the device embodiments or system embodiments. It should be noted that, in the description of the present application, "multiple" is understood as "at least two". The association relationship of "and / or" associated objects indicates that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. A and B are connected, which can represent the following two cases: A and B are directly connected, and A and B are connected through C. In addition, in the description of the present application, "first", "second", and the like are only used for the purpose of distinguishing description, and cannot be understood as indicating or implying relative importance, nor can it be understood as indicating or implying order.

[0040] The embodiments of the present application will be described in detail below with reference to the drawings.

[0041] At present, there are many modern satellite frequency points, and it takes a long time to search all the frequency points. In the actual signals of the existing satellite transmission, the transmission density of each data table is different, and the interval of some satellite SDT tables is greater than 6 seconds. This means that the software of the STB needs to wait for a maximum of 6 seconds to determine whether a frequency point has SDT information. Due to the above reasons, the time for the STB to search for a satellite is very long, and some even need tens of minutes.

[0042] In order to solve the above problem, a program search method is provided in the embodiments of the present application, in which the STB receives a program list of a specified satellite returned by a server; all frequency points in the program list are locked one by one, and it is determined whether each frequency point is successfully locked; if yes, the program corresponding to the frequency point is saved to an actual program list; if no, the frequency point is discarded. In this way, the STB can directly obtain program data in the actual program list, avoiding the need to wait for a certain time for each frequency point to determine whether there is a service description table, so that the program search can be more efficient, and the program search time is reduced.

[0043] Reference Figure 1 A flowchart of a program search method provided in the embodiments of the present application is shown, and the method comprises:

[0044] S1, receiving a program list of a specified satellite returned by a server;

[0045] Before step S1 is performed, the user can first select a specified satellite by operating the STB, and after the STB receives the specified satellite selected by the user, the STB will send a request to the server for the program list of the specified satellite.

[0046] After receiving the request sent by the STB, the server will return a program list in a specified format to the STB according to the request, and the execution format can be a conventional format such as jason or xml.

[0047] After receiving the program list in the conventional format, the STB stores the program list in a temporary storage space, and then screens each corresponding frequency point in the program list. The screened frequency points will be subjected to frequency point detection.

[0048] S2, each frequency point in the program list is subjected to frequency point locking, and it is determined whether each frequency point is successfully locked;

[0049] All the frequency points have been determined in step S1, and each frequency point in the program list is subjected to locking in this embodiment. Tuner locking or Demod locking can be used in this embodiment. It is to be noted that Tuner locking is locking a frequency point, and Demod locking is demodulating a code stream on the frequency point into a standard stream.

[0050] When the frequency point is locked, it is determined whether the frequency point is successfully locked. If the frequency point is successfully locked, step S3 is performed. If the frequency point is not successfully locked, step S4 is performed.

[0051] S3, program data corresponding to the frequency point is reserved to an actual program list;

[0052] Under the condition that the frequency point is successfully locked, the STB stores program data in the frequency point to the actual program list, so that subsequent user viewing can be facilitated.

[0053] S4, the frequency point is discarded.

[0054] Under the condition that the frequency point is not successfully locked, it is indicated that the frequency point has no corresponding signal, and the STB discards the frequency point, so that invalid search is avoided.

[0055] Through the method provided in this embodiment, program search can be more efficient, and program search time is reduced.

[0056] Further, in an optional embodiment, after program data corresponding to the frequency point is saved to the actual program list, the STB detects whether the current time exceeds a frequency point detection period. If yes, each frequency point in the actual program list is subjected to frequency point locking. If the frequency point is successfully locked, the frequency point is continuously reserved. If the frequency point is not successfully locked, data corresponding to the frequency point is discarded. If no, the actual program list is maintained. That is, the STB updates the frequency point in the actual program list in real time, and the effectiveness of the frequency point is ensured.

[0057] Based on the same inventive concept, the embodiment of the present application further provides a program searching system, referring to Figure 2 as shown, the system comprises:

[0059] a processing module 202, configured to lock each frequency point in the program list one by one, and determine whether each frequency point is locked successfully;

[0060] if yes, save the program data corresponding to the frequency point to an actual program list;

[0061] if no, discard the frequency point

[0062] In an optional embodiment, the receiving module 201 is further configured to receive a specified satellite selected by a user, and send a request for a program list of the specified satellite to the server, so that the server returns a program list in a specified format according to the request.

[0063] In an optional embodiment, the processing module 202 is specifically configured to store the program list in a temporary storage space;

[0064] In the program list, each corresponding frequency point is filtered out, and all the filtered frequency points in the program list are locked one by one.

[0065] In an optional embodiment, the processing module 202 is further configured to detect whether the current time exceeds a frequency point detection period;

[0066] if yes, lock each frequency point in the actual program list one by one, if the frequency point is locked successfully, continue to retain the frequency point, if the frequency point is locked unsuccessfully, discard the data corresponding to the frequency point;

[0067] if no, maintain the actual program list.
