Abstract

In order to realize interface standardization between a hardware layer and a general layer in China mobile multimedia broadcasting (CMMB) system, the invention provides a driving interface used for a CMMB terminal. The driving interface is arranged between the hardware layer and the general layer in the CMMB system and is used to acquire a descrambling multiplexing frame from the hardware layer and provide the descrambling multiplexing frame to the general layer. The driving interface comprises: an initialization module, which is used to operate power on and initialization on a CMMB demodulation chip in the hardware layer; a version acquisition module, which is used to acquire a version number of the CMMB system; a frequency arrangement module, which is used to arrange a frequency which is corresponding to the descrambling multiplexing frame; a channel selection module, which is used to response a watching channel selected by an instruction from the hardware layer; a descrambling multiplexing frame acquisition module, which is used to acquire the descrambling multiplexing frame.

Description

technical field [0001] The present invention relates to the field of CMMB (China Mobile Multimedia Broadcasting, China Mobile Digital Multimedia Broadcasting), more specifically, relates to a driver interface for CMMB terminals. Background technique [0002] With the public's growing demand for mobile TV services, CMMB technology has penetrated into many areas of people's lives. The development and application of various CMMB services are based on dozens of terminal platforms such as various MP4, mobile phones, and GPS.
