Problems solved by technology

This method does not affect the use of downloading terminal users when the network condition is good, but it occupies a lot of network bandwidth resources when the network condition is poor, because the EPG changes little in most of the time, when the downloading terminal frequently When requesting, it will cause a huge network overhead, and the content of the obtained electronic program list basically does not change

Embodiment

[0015] like figure 1 As shown, the electronic program guide processing method in this example can be implemented according to the following process: after starting the download terminal, a SQL-SERVER database is established on its storage medium. The reason why the SQL-SERVER database is used here is that it has a large capacity and is convenient to call. Features: Next, the user of the download terminal can request EPG data from the download server through the remote control; the download server sends the EPG data to the download terminal, and saves it in the SQL-SERVER database; every time the user requests EPG data, it will be prioritized from It can be obtained from the SQL-SERVER database. If it can be obtained, the user can select the resource he likes to download through the remote control, and add a download task to the download server. After the download is complete, you can choose to quit, or you can re-request the EPG data to add a new download task. If there is no...

Abstract

The invention relates to the network downloading technology, in particular to an electronic program list processing method in a network downloading system. The invention provides an electronic program list processing method in the network downloading system which can save network bandwidths. The electronic program list processing method adopts the key points of the technical proposal that a data base is established on the storage media of a downloading terminal; an electronic program list acquired from a downloading server terminal is stored in the data base; when being requested every time, the electronic program list is acquired from the data base; if no electronic program list exists in the data base, the electronic program list can not be acquired from the downloading server terminal. By adopting the method, the acquisition of the electronic program list is convenient and rapid; the network bandwidths are saved simultaneously; and the method is suitable for flat televisions.

Description

technical field [0001] The invention relates to network download technology, in particular to an electronic program list processing method in a network download system. Background technique [0002] With the rapid development of Internet technology and the increasing popularity of broadband Internet in ordinary families, resource sharing through the Internet has become increasingly frequent. The network download system is a system that provides network resource sharing, and it is mainly composed of two parts: a download terminal and a download server. The download terminal and the download server communicate and exchange data through a series of interfaces. The download terminal obtains a resource list, also called an electronic program list, from the download server by calling a corresponding interface, and then the user can select the resource he likes from the electronic program list to download. The EPG processing method in the prior art network downloading system adop...
