Abstract

The invention discloses a method for a set-top box to quickly acquire EPG data. The method of the invention monitors the EPG data of the DVB network through the user's set-top box. If the EPG data changes, the set-top box uploads the current EPG data to the EPG storage server, and the user's set-top box queries the EPG data from the EPG storage server and displays it to the user. The EPG storage server receives and saves the EPG data uploaded by the user's set-top box, and the EPG storage server receives the query command of the user's set-top box, and transmits the stored EPG data to the user's set-top box. The method of the invention makes the EPG storage space almost infinite, and can store a large amount of EPG data. The speed of the user's set-top box to obtain the EPG data also breaks through the limit of local filtering and analysis, and all the EPG data can be obtained as soon as the device is turned on.

Description

A method for fast acquisition of EPG data by a set-top box

technical field

The invention belongs to the technical field of digital set-top boxes, and in particular relates to a method for a digital TV set-top box to quickly acquire EPG data.

Background technique

After the TV industry has entered digital TV from analog TV, many new service forms have emerged, among which EPG (Electronic Program Guide, Electronic Program Guide) is a very important new service. Using the menu provided by EPG, users can choose their favorite multicast channels; order their favorite video programs; sing their favorite songs online; find various information provided by IPTV, including life information, entertainment information, education information, sports information Wait. The user can also use the EPG menu to view additional information of the program, such as the introduction of the program content, the introduction of actors and directors, and so on. At the same time, through the parental control function provided in the EPG menu, parents can restrict certain programs and not open all viewing rights to their children.

The birth of EPG has greatly enriched the digital TV business and provided users with convenient and practical digital TV applications. It can be said that EPG stuffs traditional TV newspapers, TV magazines and other functions into a small set-top box, and expands its functions. Its functions not only cover the scope of traditional newspapers and magazines, but also derive from traditional newspapers and magazines. New format.

EPG has two important performance requirements: one is receiving speed; the other is storage capacity. The receiving speed requires that the set-top box can quickly search the EPG information in the DVB network, and its influencing factors include: 1. The transmission speed of the EIT table in the DVB network; 2. The algorithm for filtering EIT and analyzing EIT; 3. The amount of EPG information in the DVB network . The traditional optimization speed can only start from filtering EIT and parsing EIT, but there are obvious bottlenecks.

The storage capacity requires that the set-top box can store as much EPG information as possible, but limited by the capacity of the local storage of the set-top box, the amount of EPG information in some DVB networks is as high as tens of MB, and it is generally impossible for the set-top box to store it completely.

Contents of the invention

The purpose of the present invention is to provide a method for the set-top box to quickly obtain the EPG.

The method of the invention monitors the EPG data of the DVB network through the user set-top box, if the EPG data changes, the set-top box uploads the current EPG data to the EPG storage server, and the user set-top box queries the EPG data from the EPG storage server, and displays it to the user. The EPG storage server receives and stores the EPG data uploaded by the user's set-top box, and the EPG storage server receives the query command from the user's set-top box, and transmits the stored EPG data to the user's set-top box.

The specific process of user set-top box monitoring EPG data and uploading to EPG storage server is:

Step (1) the user set-top box starts the EPG data monitoring task;

Step (2) user set-top box sends handshake information to EPG storage server, carries out handshake with EPG storage server, if handshake failure then execution step (3), if handshake success then execution step (5);

Step (3) If the number of failed handshakes does not reach the handshake limit, then continue to shake hands and execute step (2), otherwise execute step (4);

Step (4) exits monitoring, returns error state;

Step (5) user set-top box carries out the EPG data filtering and parsing of DVB standard once, and executes step (6);

Step (6) uploads the EPG data after filtering and parsing to the EPG storage server, and executes step (7);

Step (7) user set-top box monitors the EPG data in the DVB network, executes step (8);

Step (8) The user's set-top box judges whether the EPG data in the DVB network changes, and if there is a change, the step (2) is executed, and if there is no change, the step (7) is executed.

The specific process of EPG storage server is:

Step (a) the user starts the EPG storage server;

Step (b) EPG saves the information or data that the server waits for the user's set-top box to send, including handshake information, query information and EPG data: if the EPG saves the server and receives the handshake information, then executes step (c); if the EPG saves the server and receives the EPG data , then execute step (d); if the EPG storage server receives the query information, then execute step (g);

Step (c) The EPG storage server shakes hands with the user's set-top box, and returns the handshake success message to the user's set-top box, and continues to perform step (b);

Step (d) The EPG storage server parses the EPG data, and performs verification, and if the verification is successful, step (e) is executed; if the verification fails, step (f) is executed;

Step (e) EPG preservation server saves the EPG data after parsing to local EPG database, continues execution step (b);

Step (f) EPG saves the server and deletes the cache, and proceeds to step (b);

Step (g) EPG saves the server analysis query information, according to the EPG query parameter in the query information, searches whether there is matching EPG data in the local EPG database, if there is, then execute step (h), if not then execute step (i);

Step (h) EPG storage server sends the matching EPG data to the user's set-top box, and continues to perform step (b);

Step (i) The EPG storage server notifies the user that the set-top box has failed to query, and continues to execute step (b).

The specific process of updating the EPG data by the user set-top box is as follows:

Step Ⅰ. The user set-top box starts the EPG data update;

Step Ⅱ. The user set-top box sends the query information containing the EPG query parameters to the EPG storage server. If the user set-top box does not obtain the EPG data from the EPG storage server, then perform step Ⅲ. If the EPG data is obtained, then perform step Ⅴ;

Step Ⅲ. Whether the query limit is reached, if the query limit is reached, step Ⅳ is performed, if the query limit is not reached, step Ⅱ is performed;

Step Ⅳ. Stop updating EPG data;

Step Ⅴ. The user set-top box parses the EPG data obtained from the EPG storage server;

Step VI. The user set-top box saves the parsed EPG data to the local memory.

The method of the invention is based on the Ethernet and the set-top box, and designs a set of methods that can quickly acquire programs in the DVB network, and can also store a large amount of EPG data without limitation. By adopting the method of the present invention, the EPG storage space is almost unlimited, and a large amount of EPG data can be stored. The speed at which the user set-top box obtains the EPG data also breaks through the limit of local filtering and analysis, and all the EPG data can be obtained as soon as it is turned on.
