Generation Broadcasting-Wireless, radio and television of future generation-wireless) technology, more particularly to a kind of fusion list
To broadcast singal and bidirection internet signal change the node system integrating device of propagation.
Background technology
At present, the main path watched in China or even the whole world live and/or program request digital television program can
To be divided into two ways：First, with traditional DVB-S, DVB-T, DVB-C DTV STB come it is corresponding receive satellite, ground,
Cable digital TV One-to-All Broadcast or two-way interaction program request signal, then audio-video signal is connected to TV and showed；2nd, it is sharp
With IPTV, OTT, intelligent television, smart mobile phone etc., live or request program is obtained by being fetched to the chain of bidirection internet, then
Audio-video signal is connected to TV or directly showed on mobile phone.
First way is the most traditional, and live program channel number, definition, stability are all fine, but can only be confined to electricity
Depending on upper presentation, and every TV must all configure set top box, can not meet increasingly increased smart mobile phone, tablet personal computer gradually
Rating demand, along with its monthly rental is high, market is even more swallowed by network machine top box and intelligent television gradually.
The second way is arisen in the case of family's two-way broadband network promotion, and its flexibility is strong, is watched straight
Broadcast, request program without other monthly rent, but live channel number, definition are all not so good as first way, also easily by bandwidth
Limitation causes stability bad.
The content of the invention
In order to solve the above problems, the present invention provides a kind of node system merged unidirectional and two-way signaling and change propagation
To unite integrating device, it incorporates above two resource acquisition mode, the advantages of having gathered One-to-All Broadcast, bidirection internet, and
The performance of each module has been given full play to, each target terminal flexible access has finally been allowed with WIFI circulation way, it has structure group
Close the novel, utilization of resources rationally, efficiency high, the characteristics of speed is fast, flexibility is strong, and stability is good, and compatibility is good, and expansion is good.
