specific Embodiment approach

[0026] Regional broadcasting based on a one-way network is only suitable for large-area coverage, and cannot adapt to small-area coverage such as industrial users. After repeated discussion and verification, combined with the two-way network coverage in Wuxi, the branch company formulated the PSI / SI two-way regional broadcast expansion specification, using the two-way IP channel to realize the two-way regional broadcast, and can flexibly increase and adjust channels within the region. Its specific implementation is as follows:

[0027] System Architecture:

[0028] Such as figure 1 As shown, the front-end broadcasting system transmits radio and television generation transmission programs, the front-end computer room transmits the unified front-end program signal through the radio network, the channel list configuration server transmits and configures the user channel list, and the set-top box uses a two-way channel to read the channel list configuration server according to th...

Abstract

The invention discloses a digital television personalized program selecting and sorting method which comprises the following steps: realizing bidirectional area broadcasting at a broadcasting end and a user end by utilizing a bidirectional IP (Internet Protocol) channel, identifying regional grouping of a user by an ID (Identification) number of a BAT (Bouquet Association Table), i.e. bouquet_id in an intelligent card; arranging a channel list configuration server at the broadcasting end for generating and transmitting a channel configuration list; reading the bouquet_id in the intelligent card through a set top box at the user end, receiving the channel configuration list equivalent with the bouquet_id in value through a channel list document in the bidirectional network visit channel list configuration server if the bouquet_id is larger than a set feature value and processing channel search according to the configuration list; and editing the serial numbers of all channels again by utilizing the received channel configuration list at the user end or adding television programs with own contents. The digital television personalized program selecting and sorting method has the benefits that the digital television personalized program selection and sorting, the local content insertion and other personalized business needs of township and industry users in a broadcasting network are solved; and meanwhile, the management and the control of radio and television contents in an area are realized.
