Embodiment Construction

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

[0030] The embodiment of the present invention provides a data card, such as figure 2 shown, including:

[0031] Terrestrial digital video broadcasting DVB-T receiving module 210, universal mobile telecommunications system UMTS (Universal Mobile Telecommunications System) module 220;

[0032] DVB-T receiving module 210 is connected in series with UMTS module 220; Wherein,

[0033] The DVB-T receiving module 210 is used for receiving the terrestrial digital video broadcasting signal, filters the received signal according to the program identification filter condition sent by the UMTS module 220, and sends the filtered signal to the UMTS module 220;

[0034] The UMTS module 220 is used to obtain and send the program identification filter condition to the DVB-T receiving module 210 according to the instruction of the user terminal, ...

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 ...
