Method for playing television programs by mobile terminal

Abstract

The invention discloses a method for playing television programs by a mobile terminal. The method comprises the following steps that: A, at least two mobile terminals request a television program receiving device to play the television programs; B, the television program receiving device classifies audio / video playing capacities of each mobile terminal; C, the television program receiving device carries out encoding in different manners and broadcasting on the television programs according to encoding parameters corresponding to the audio / video playing capacities of different kinds of mobile terminals; and D, each mobile terminal receives the television programs in the corresponding encoding manners, and decoding and playing the television programs. According to the method for playing the television programs by the mobile terminal, the smooth and undistorted playing of the television programs by the mobile terminals having different terminal performances at the same time can be realized.

Description

Technical field [0001] The invention relates to a method for playing TV programs on a mobile terminal. Background technique [0002] In recent years, China's digital TV industry has developed in an all-round way. Cable digital TV has continued to advance to its peak, terrestrial digital TV has been officially implemented, and satellite live broadcasting has begun to enter the industry cultivation period; the investment and financing policies of digital TV have been further liberalized, and the machine-card separation system has been gradually implemented. The industrialization process of digital TV has been accelerated. [0003] Due to the scalability, scalability, and interoperability of digital TV, it is convenient to transmit in various communication channels, especially in asynchronous transfer mode (ATM) networks, and also to communicate with computer networks. Enables interaction between digital TV and other digital devices, especially portable digital devices. For example,...

Problems solved by technology

However, this method has a problem that cannot be ignored. Different mobile terminals have different screen resolutions and audio and video decoding capabilities (terminal performance). For those mobile terminals with relatively low audio and video decoding capabilities or relatively low screen resolution For example, simply receiving TV program data from a digital TV cannot help it achieve smooth audio and video playback

Specifically, compared with mobile terminals with high-performance audio and video decoding capabilities, mobile terminals with lower audio and video decoding capabilities need to occupy more system resources and data processing time when processing the same digital TV program data, which will cause Affect the normal broadcasting of TV programs, such as picture distortion, playback interruption, discontinuity, etc., and even cause crashes, affecting the normal use of other functions of the mobile terminal

It can be seen that the problem brought by the above-mentioned invention is that mobile terminals with different audio and video decoding capabilities cannot play TV programs smoothly and without distortion at the same time.
