Embodiment approach

[0098] On the basis of the above embodiments, this embodiment involves a specific process of generating an EPG according to event information in the second storage space, that is, Figure 6 A schematic flow chart of Embodiment 4 of the EPG information generation method provided by the present invention, as Figure 6 As shown, another specific implementation method of the above step S203 is:

[0099] S401. Receive an event information query instruction.

[0100] The event information query instruction may be issued by an upper-layer application, wherein the upper-layer application may issue the expired data clearing instruction according to a user's instruction. The upper-layer application can provide users with query functions in different dimensions, for example, query by time, query by service (channel) type, query by event (program) type, etc. The query function can also be a combination of different query conditions. For example, the user can select "query all variety sh...

Abstract

The invention provides an electronic program guide (EPG) information generating method and device. The method comprises the steps of: creating a plurality of first threads corresponding to event information tables (EITs) one by one; executing the plurality of first threads, wherein the first threads are used for filtering the EITs corresponding to the first threads from transport stream (TS), analyzing the EITs corresponding to the first threads, acquiring event information corresponding to the EITs corresponding to the first threads and storing the event information in first storage spaces corresponding to the first threads one by one; and generating an EPG according to the event information in all the first storage spaces. According to the method, the operation of the EITs with huge data volume is executed in parallel by the plurality of threads through creating and executing the first threads corresponding to the EITs in quantity, so that the EPG information updating speed is greatly improved and then the user experience is improved.

Description

technical field [0001] The invention relates to computer technology, in particular to a method and device for generating EPG information of a television program guide. Background technique [0002] Electronic Program Guide (EPG for short) is an important function in digital television technology. EPG refers to inserting service information (Service Information, SI for short) defined by the standard into a transport stream (Transport Stream, TS for short) that conforms to Digital Video Broadcasting (DVB) and other standards, so that the receiving end (such as a set-top box) ) can extract the list and broadcast parameters of programs broadcast by the program provider from the TS stream, and display them to digital TV users in an intuitive form, so that users can conveniently select and watch digital TV programs. Among them, SI defines different tables, and each table represents a type of data, and the receiving end will organize the data provided by SI, and finally present it...
