Abstract

A method for transmitting digital TV data of mobile terminal includes setting up logic interface between each hardware communication interface and TCP / IP protocol stack and confirming the corresponding relation of the two, assigning its used logic interface by each TCP / I application when TCP / IP communication interface is started up, using TCP / IP protocol stack to transmit digital TV signal data together with the other TCP / I application data and calling on its receiving function to receive digital TV signal data in TCP / IP application data by corresponding hardware communication port according to corresponding relation of logic interface to hardware communication port.

Description

technical field [0001] The invention belongs to the field of mobile communication and digital television, and specifically provides a method for introducing digital television signal data into a TCP / IP protocol stack for subsequent processing and display. Background technique [0002] Currently, mobile communication terminals supporting data packet services all include a TCP / IP protocol stack, and the physical device for input / output thereof is a radio frequency module for wireless communication. For digital TV services based on IP data, the TCP / IP protocol stack is necessary. However, after the digital TV signal data is received by the digital TV receiving module, it is sent to the baseband processor through data buses such as USB, SDIO and SPI. In the current mobile TV solution, the digital TV sent via the data bus is usually sent to the multimedia processing chip, and the player running in it performs processing. Since the multimedia processing chip is independent from ...
