Description
Technical field
The present invention relates to digital TV field basically, more specifically, and a kind of method that adds interference service.
Background technology
Along with the development of Digital Television, the kind and the quantity of audio-video frequency content and data broadcast content increase gradually, and content arrangement, professional scrambling, program are play on time, channel program switching in time etc. all had higher requirement to the efficient of digital television system.According to the playing programs timetable, each audio/video program or data broadcast program have fixedly reproduction time at specific channel.When adding channel program or switching channels program, a kind of method is at audio/video coder or/and configuration service router between broadcast data server and the scrambler, by the Business Stream that transmits in the configuration service IP control figure television system, play the program of setting at the appointed time with the realization channel, change professional IP and realize that channel program switches; Another kind method is at one time can only business features of scrambling according to same scrambler, switches with the program of realizing channel according to the interface parameters of business configuration scrambler and audio/video coder or broadcast data server, multiplexer.These two kinds of methods all are to realize that by the human configuration interface parameters channel program switches, and can cause the program short interruption in the human configuration parametric procedure, can not realize the smooth conversion of program.And first method is when increasing new business, and (Conditional Access: the Schedule condition receiving system) (arranging service) shows, and can cause the CA can't operate as normal, is unfavorable for that CA effectively controls if there not be in time ServiceID to be write CA.Therefore how to improve on second method to realize that channel program automaticallyes switch on time, it is particularly important that smooth playing seems.
As shown in Figure 1, be audio/video program timesharing playing principles figure in the system, professional 1 and professional 2 all by exporting to the same interface of multiplexer after the scrambler scrambling, and promptly professional 1 and professional 2 in same cannel broadcast.According to playing programs timetable (as shown in Figure 2): professional 1 program be every day 00:00:00-09:00:00 play, professional 2 program is 09:00:01-23:59:59 broadcast every day, can realize that by the relevant interface parameter that changes scrambler the timesharing of same channel program is play.
In digital television system, scrambler at first reads audio frequency and video business in the audio/video coder or the data service in the broadcast data server; Secondly, scrambler and CAS (Conditional AccessSystem: condition receiving system) carry out data interaction, finish the professional and data service scrambling of audio frequency and video; At last, scrambler sends to the multiplexer corresponding port with the business of scrambling.Professional through sequence of operations, send to terminal by broadcast channel.
First kind of technical scheme that industry is used always as shown in Figure 3.
Two audio frequency and video business in same channel different time broadcast for by same scrambler scrambling at first dispose with close interface parameters in scrambler according to the audio frequency and video business.Then according to the playing programs time, before professional 1 playing programs, according to the interface parameters of professional 1 configuration scrambler with audio/video coder, multiplexer, the program of the specific channel display business 1 of terminal at this moment; Before professional 2 playing programs, the interface parameters of deletion professional 1 is according to the interface parameters of professional 2 configuration scramblers with audio/video coder, multiplexer, the program of this channel display business 2 of terminal at this moment.Said method switches by the program that disposes scrambler relevant interface parameter and realize same channel on time.In the program handoff procedure, because the manual operation meeting causes channel program smooth not change.
Second kind of technical scheme that industry is used always as shown in Figure 4.
For two audio/video programs in same channel different time broadcast by the scrambling of different scrambling device, at first in two scramblers, dispose respectively with close interface parameters according to the audio frequency and video business, according to two playing programs times, before professional 1 playing programs, according to the interface parameters of professional 1 configuration scrambler 1 with audio/video coder, multiplexer, the program of the specific channel play service 1 of terminal this moment.After professional 1 program finishes, the interface parameters of deletion scrambler 1 and multiplexer; Before professional 2 the playing programs, the interface parameters of configuration scrambler 2 and audio/video coder, multiplexer, the program of the specific channel play service 2 of terminal this moment, after professional 2 program finishes, the interface parameters of deletion scrambler 2 and multiplexer.Such scheme switches to realize channel program by the interface parameters that disposes and delete each scrambler and the same port of multiplexer on time, owing to need human configuration relevant interface parameter, in the program handoff procedure, program can not smoothly broadcast.
Above-mentioned two kinds of schemes all have following shortcoming:
Program switches needs the relevant interface parameter of human configuration scrambler, thereby causes in the program handoff procedure, and program can not smooth be changed.If it is manually-operated loaded down with trivial details that often professional and broadcast situation can cause when complicated.
