Embodiment Construction

[0037] The technical scheme of the invention is as follows: firstly, multiple channels of video data streams are received and processed simultaneously to obtain multi-program multiplexing streams. Then, cycle number all data segments. Error correction and label processing are performed on each channel. Finally, according to the size of each video program stream, it is grouped and interleaved adaptively, and then sent in the form of multi-channel program data, that is, multiple program data streams are received and sent at the same time. In this way, the transmission and distribution of multi-channel video program data in the wireless WiFi system can be easily realized, and the simultaneous access of multi-programs and general multi-users can be realized.

[0038] Specifically, a distribution method of a wireless WiFi multimedia broadcasting system, such as figure 1 shown, including the following steps:

[0039] Step A, collecting multiplexed streams of video programs.

Abstract

The invention discloses a distribution method and distributer of a wireless WiFi multimedia broadcast system. First of all, a multi-program multiplexing stream is obtained by receiving and processing a multipath video data stream simultaneously, then, cyclic numbering is performed on all data segments, each path is subjected to error correction and marking processing, finally, adaptive grouping and interlacing are performed according to the size of each video program code stream, and then, the stream is sent in the form of multipath program data, i.e., a multipath program data stream is received and sent simultaneously. In such a way, multipath video program data can be easily transmitted and distributed in a wireless WiFi system, and multiple programs and multiple general users can be simultaneously accessed. Transmission of a multi-program data stream can be realized within a certain area scope, the stability and the speed of data transmission are improved, and high-definition and smooth video play at general user ends is guaranteed.

Description

technical field [0001] The invention relates to the technical field of multimedia information dissemination, in particular to a distribution method and a distributor of a wireless WiFi multimedia broadcasting system. Background technique [0002] The communication mechanism adopted by the existing wireless WiFi system is the mode of "cutting the cake", that is, the access of each user directly occupies its own bandwidth and data flow. With this communication mechanism, as the number of users increases, the data transmission rate of the wireless WiFi system will decrease rapidly. Especially when the video information is disseminated, there will be a phenomenon that the video playback is not smooth, and in severe cases, there may even be a problem that the video information cannot be received and played. And people hope that the wireless WiFi video playback system can not only accommodate more general mobile users to access at the same time, but also ensure the quality of dat...
