Embodiment Construction

[0037] The first embodiment of the present invention provides a broadcast method.

[0038] Please see figure 1 , which is a flowchart of the first embodiment of the present invention. The following combination figure 1 This example will be described.

[0039] Step S101, providing a terminal code for each terminal.

[0040] The broadcasting method needs to implement grouping of terminals, and the broadcasting signal is divided into different signal segments, each signal segment corresponds to a different grouping, so as to realize group broadcasting. In order to realize terminal grouping, a terminal code corresponding to the terminal shall be provided for each terminal, and the terminal code shall be memorized by the terminal. Each terminal is set with a unique terminal code, and it is also convenient to change the group to which the terminal belongs at any time as needed, increasing flexibility. Providing terminal coding for each terminal is the premise of realizing packe...

Abstract

The invention provides a broadcasting method, comprising the steps of: providing a terminal code for each terminal; dividing terminals into groups according to the terminal codes as required; adding a terminal code of a terminal contained in one group into a broadcast signal segment broadcasted by the group; broadcasting each broadcast signal segment; judging by each terminal whether some broadcast signal segment contains a terminal code of the terminal or not; if so, broadcasting the broadcast signal segment; otherwise, not broadcasting the broadcast signal segment. The invention further provides a broadcasting system at the same time for realizing the broadcasting method. According to the invention, different information can be broadcasted to terminals in different groups, an advantage of easy establishment of the broadcasting system is used, broadcast contents are strong in pertinence, and group transmission requirements in some specific application occasions are better satisfied.

Description

technical field [0001] The present invention provides an information spreading method, especially a broadcasting method. The invention also provides an information dissemination system, especially a broadcast system. Background technique [0002] Broadcast technology is a technology for sending information from one point to an unspecified receiving terminal. Various broadcasting technologies are widely used in daily life and industry. For example, audio broadcasts received by radios, video broadcasts received by televisions, etc., all belong to broadcasting technology. Compared with point-to-point transmission, broadcast technology is cheaper and can transmit information quickly and widely. [0003] A major drawback of traditional broadcasting technology is the lack of pertinence. In many cases, it is desired that the broadcast content is only broadcast by a specific terminal, or that a certain terminal only broadcasts information related to it, while other information i...
