Embodiment Construction
[0022] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0023] This example figure 1 , figure 2 , image 3 , Figure 4 As shown, a method for inserting programs run by suburban counties in a digital television broadcasting network, including using encoders, demodulators, multiplexers, modulators, mixers, and terminal receivers to implement self-run programs in suburban counties For program insertion, the terminal receiver is selected as the terminal set-top box, and the user receives the self-managed program through the display device TV, and the city network broadcasts the radio frequency signal of the city network PSI information, and broadcasts the whole network SI information at a fixed frequency point. The whole network SI information includes City network SI information and suburban county SI information.
[0024] The present embodiment realizes interleaving through the following steps:...

The invention provides an insertion method of suburban districts self-management programs in digital television broadcasting network that includes using an encoder, a demodulator, a multiplexer, a modulator, a mixer and a terminal receiver equipments to implement insertion of suburban districts self-management programs, the suburban districts self-management programs are multiplexing configured asbaseband signal according to corresponding suburban districts SI information, the baseband signal is regulated as a first program flow by the modulator and then together with city network signal transported to the mixer for mixing processing, and the sending the mixed second program flow to the terminal receiver for comparison and filtering to get a EPG electric program list of suburban districtsself-management programs, then displaying the suburban districts self-management programs on display device. The invention shares total frontend resource of city network and uses PSI / SI information corresponding relationship to implement filtration of terminal electric program list information, and implements insertion of suburban districts self-management programs in digital cable TV centralization network under the premise of easy and reliable, resource saving and reduced cost.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a method for interpolating self-managed programs in suburban counties in a digital television broadcasting network. Especially in suburban counties that do not have their own business front-ends and cannot uniformly configure PSI / SI information, but need to insert and broadcast self-managed programs, the whole network SI information and city network PSI information are uniformly broadcasted through the main front-end of the city network, and the sub-headends are inserted Run programs by yourself and modify PSI information, rationally configure digital TV terminal receivers, and realize the insertion of self-run programs in suburban counties in the digital TV broadcasting network. Background technique [0002] After the digital conversion of China's cable TV, the unified network planning of the whole city is adopted, that is, the network deployment is carried out through the...
