Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] The solution of the present invention adopts the method of integrating multiple NIM drivers in the software, as shown in FIG. 2 . It should be noted that although these NIM drivers seem to exist side by side in the program, only one driver may be loaded and executed during the actual program running, so it does not affect the execution efficiency, but only occupies more storage space.

[0031] In order to facilitate loading of the driver, the software part of the present invention needs to define a unified NIM chip driver interface, a unified NIM property structure, and a unified frequency point information structure.

[0032] First, a unified chip driver interface.

[0033] The chip driver is mainly provided by the manufacturer of the network interface chip. Chip drivers have the characteristics of diversity. However, regardless of t...

Abstract

The method comprises: unifying the driving interface of NIM chip, the NIM structure and the frequency-point information structure; identifying the NIM module driver, and load NIM module driver. The invention can be compatible with different type and different model network interface module, and can change the network interface by using plug-in and plug-out after power-off.

Description

technical field [0001] The invention belongs to the field of broadcast communication, in particular, the invention relates to a loading method of a network interface module of a digital TV set-top box. Background technique [0002] Digital Video Broadcasting (DVB) is a set of protocols developed by the European Telecommunications Standards Committee that can be used to transmit digital TV, digital audio and data. In the DVB application environment, the DVB service provider broadcasts digital video, audio and data streams in DVB format to users at the other end through the communication network. The user end receives the front-end broadcast program through a decoding device, that is, a receiver set top box (STB). [0003] NIM (Network Interface Module) network interface module is the interface between the receiver set-top box and the external network. It has three main functions: 1. Realize communication with the main chip, interpret and execute the control commands of the ...
