Embodiment Construction

[0019] The present invention provides a program link playing method. In order to make the object, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] see figure 1 , which is a flow chart of the program link playing method of the present application. As shown in the figure, the program link playing method includes the following steps:

[0021] S1. Monitor the private table in real time, and obtain the linkage descriptor content in the private table;

[0022] S2. Obtain the current program information, and judge whether there is playback control information of the program in the linkage descriptor, if so, proceed to step S3, otherwise proceed to step S4;

[0023] S3, judging whether the current program is playing the specified li...

Abstract

The invention discloses a program linkage broadcasting method. The method comprises the following steps of: firstly, monitoring a private table in real time, and obtaining linkage descriptor content in the private table; then, obtaining the current program information, and judging whether the linkage descriptor contains the broadcasting control information of the program, if so, broadcasting the linkage broadcasting program specified in the descriptor. Thus, rebroadcast realized by broadcasting same content at different frequency points is not needed, bandwidth sharing in a broadcast mode is realized, and the method has the characteristics of being high in bandwidth utilization rate, simple to control, and so on.

Description

technical field [0001] The invention relates to the technical field of television program playing, in particular to a program link playing method. Background technique [0002] At present, the era of information is becoming more and more abundant, and bandwidth resources are correspondingly more and more precious. During the broadcasting of TV programs, many of the contents actually broadcast by each channel are the same. For example, daily news broadcasts, some important sports games, political meetings, etc.; many channels use the rebroadcast method to play the content at each channel frequency point: that is, the content occupies a certain bandwidth at each frequency point to play. That is to say, in this way, multiple different programs on multiple different frequencies are transmitting the same program data content at the same time. For example, in the daily news broadcast, almost all satellite TV programs broadcast the same content on their respective frequencies. ...
