Embodiment Construction

[0037] A kind of wireless WiFi multimedia broadcasting method, such as figure 1 As shown, it specifically includes the following steps:

[0038] Step A, acquisition of program signal source.

[0039] The signal source of the program is obtained from broadcast TV satellite, cable digital TV, terrestrial digital TV, IPTV (Interactive Personality TV) or local plug-in card.

[0040] Program signal sources include multi-channel live programs (IP / TS), media advertising information (TCP / IP), local information (TCP / IP) and comprehensive information release system, etc.

[0041] The data stream format of the program signal source includes the following three formats: 1) Process the received multiple single-channel program IP streams into single-channel multi-program IP streams; 2) Multi-program transport stream (Multi-program transport stream, MPTS ), each single-program transport stream (Single-program transport stream, SPTS, referred to as TS) is obtained after demultiplexing and t...

Abstract

The invention discloses a wireless WiFi multimedia broadcasting system and a wireless WiFi multimedia broadcasting method. A carrier-class WiFi device is used for establishing a coverage system in a limited range; a sending end consists of 7 parts, namely, a program source collecting part, an on-demand program stream multiplexing part, a program stream resynthesizing processing part, a data streams sending and transmitting part, a mobile client receiving part, an adaptive feedback part and a video playing part. A multi-program TS stream is multiplexed on demand into a plurality of data streams in forms of program IP packets, and a network synthesis controller capable of receiving and processing multiple channels of stream media at the same time is constructed, so that the data streams can be sent in a broadcasting manner to achieve simultaneous reception of a large batch of smart mobile phone terminals and simultaneous playing of multiple programs. By a wireless WiFi IP broadcasting technology based on digital TV and other multimedia information, in relatively large service scenes (terminal buildings, meeting places, waiting halls, mobile compartments, residential areas, tourist areas and the like), simultaneous reception of more mobile phones (more than 32) and other smart terminals can be achieved during IP live broadcasting of the digital TV and the other multimedia information.

Description

technical field [0001] The invention relates to the technical field of multimedia information dissemination, in particular to a wireless WiFi multimedia broadcasting system and method applicable to general mobile terminal equipment. Background technique [0002] In realizing the integrated development of broadcasting, television and communication, how to solve the terminal integrated reception in the live broadcast of multimedia information such as video has become one of the symbols. In the communication industry, before 5G and other new-generation communication technologies are realized, the 3G / 4G mobile communication field is constrained by the technical realization mechanism (information interactive communication, etc.), the delay in presenting live video with large amounts of data is too long, and the consumer terminal consumption burden is too heavy (Traffic charges) and other disadvantages are difficult to fundamentally eliminate. In the research and development of d...
