Abstract

The invention discloses a method using information loaded by Mpeg II video stream to establish a reliable transmission channel. A loader and an unloader are respectively arranged in a centralized control type simulcast system architecture, and the technical scheme utilized by the method is as follows: (1) constituting scattered bits obtained during a video loading process into a bit stream; (2) designing a protocol data unit on the basis of the bit stream; and (3) establishing a transport protocol to realize a reliable and stable transport channel through data unit synchronization and various error control. The invention has the advantages that the transmission channel can cover and transmit to areas capable of being covered by satellite signals along with television signals and satellites, which has wide obtained coverage, small transmission cost and good synchronization, thus facilitating a center emitting signals to centrally control the subsystems to load important information and realizing the control on far simulcast subsystems within the coverage area of satellite signals.

Description

technical field [0001] The invention relates to a technique for establishing a reliable transmission channel in an MpegII video stream by using MpegII video stream information loading and unloading technology. A technique for the control of the ground simulcast subsystem. Background technique [0002] At present, in the technical field of video stream information carrying technology, the video transmission is unstable, there are many errors, and the working image is distorted. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for obtaining a statistically stable and reliable information transmission channel that is not limited by the speed of the video transmission stream on the basis that the video image meets the broadcast-level image specification. [0004] In order to solve the above technical problems, the present invention provides a kind of method utilizing Mpeg II video stream carrying information...
