Data card and data transmission method

Abstract

The embodiment of the present invention discloses a data card and data transmission method. The data card includes a floor digital video broadcast DVB-T receiving module, and a Universal Mobile Communication System UMTS module. Through the connection of the UMTS module and DVB-T receiving module, the UMTS module can indicate the PID filtering condition of the DVB-T receiving module according to the instruction of the user terminal, to realize the dynamic filtering to the output PID; and effective filtering can be performed to the DVB-T output signals and user side receiving signals through a UMTS module.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a data card and a data transmission method. Background technique [0002] The combination of TV receiving equipment and other equipment, such as computers, mobile phones, etc., has produced many new products, which meet the needs of people watching TV anytime and anywhere. Therefore, studying how to combine digital TV broadcasting technology with other digital technologies has become a research direction with great significance. [0003] In terms of DVB (Digital Video Broadcasting, digital television broadcasting), Europe was the first to carry out research and standard formulation. The digital television broadcasting standard it established was supported by the ITU (International Telecommunication Union International Telecommunication Union). The standards include: DVB-S, DVB -C and DVB-T, respectively suitable for satellite TV, cable TV and terrestrial ...
