Description
Technical field
Type of the present invention relates to a kind of communications zone recognition methods, digital television business area recognition method in particularly a kind of one-way digital television broadcasting network.
Especially in the centralized unilateral network of city's net unified planning, different districts or other have the area of managing program by oneself need extract under the situation that area information disposes local digital television business, terminal receiver goes out local zone information by PSI information and SI information filtering, front end is broadcast the zone and is selected control information to offer terminal receiver as the service filter reference, realizes the zone identification of digital television business.
Background technology
Adopt whole city's network unified planning after China's cable television digital turn over, promptly carry out network design by the mode of general headend and sub-headend.City's net central machine room is built the general headend system, and radiofrequency signal directly covers the mode networking of each district branch company.Each district branch company of subordinate does not have own professional sub-headend, by equipment such as network adapter, multiplexer, modulators, receives the content of city's net general headend, and the network by each branch company of suburban county oneself offers user in oneself the net again.The whole network SI information is broadcast in city's net general headend unification, and branch company of suburban county intercuts and manages programme content by oneself and improve PSI information, shares the whole network SI information that general headend is broadcast simultaneously.
Yet, because the especially mode of value-added service of digital television business is carried out in the general headend unification, can not judge the zone at set-top box users place effectively, suburban county also can't carry out the Digital Television specific transactions with local characteristic, suburban county after the integration faces the awkward situation that traditional business runs off, and need solve corresponding problem by area recognizing method.
