Abstract
The invention belongs to a universal digital television playing method with an android terminal and specifically relates to a universal digital TV playing method based on an android terminal device. A digital TV based on an android system is equipped with playing software and is connected with a cable TV cable through a USB digital TV receiver. The digital TV based on the android system calls an internal search program to search the USB digital TV receiver which is connected with the TV and obtains the communication permission with the receiver after the USB digital TV receiver is found. The android-system-based digital TV which obtains the permission establishes an HTTP server through a standard socket, receives TS data provided by the data processing module, and calls player software to play a program. According to the method, an android system player is called, the connection of an external device with different android platform bottom layers is not needed, and the universality of the external device is greatly enhanced. Digital TV video data is converted into streaming media through software, then the android system player is called to complete the playing of the streaming media, and the development time is greatly reduced.
