Abstract
The invention discloses a method for switching TV programs. In the method, at least two de-multiplexers are used on a TV set. When one de-multiplexer in a current working condition provides the data of the current programs, other de-multiplexers in an idle condition build data channels for a next target program to be probably switched according to a channel switching prediction algorithm; when the TV set receives channel switching instructions, the de-multiplexer in the current working condition is switched into the idle condition, and the de-multiplexers for building data channels for target programs are switched into the current working condition to provide current program data for the TV set. The method has the advantage of high channel switching speed.
Description
Technical field
The present invention relates to digital TV field, relate in particular to a kind of TV program switching method.
Background technology
In recent years, the Digital Television development is swift and violent, and digital television service has been come into huge numbers of families gradually.Along with program service ground constantly increases, when program is enriched in enjoyment, endless worries also have been absorbed in.Operator provides programs up to a hundred, allows the user have more visitors or business than one can attend to.From the rendition list, all programs of once-over owing to be subjected to the restriction of speed ground, can spend many times of user successively, change platform and have become a very loaded down with trivial details thing.
In changing the process of platform, demultiplexer (DEMUX) is being played the part of important effect in set-top box, it extracts active data from TS stream, offer upper layer application, comprises programs broadcast information necessary such as the most basic audio, video data and various SI table.When switching program, the way of prior art is to adopt a DEMUX to carry out all platforms that changes to operate, before switching to a new program, need stop the work of current DEMUX, close data channel then, open new data channel according to the programme information that will switch again, start DEMUX at last and enter ready state; After switching to a new program, DEMUX begins to receive needed data again, and DEMUX prepares new data channel needs the regular hour, and Data Receiving has certain time delay, has influenced the speed of switching playing programs behind the program.Because these activities occur in the user and change in the platform task, so directly have influence on the speed that the user changes platform.
Therefore, how to solve television set and change the slow-footed problem of platform, become one of technical problem of current urgent need solution.
Summary of the invention
The purpose of this invention is to provide a kind of television set that can make and change the fireballing TV program switching method of platform.
For solving technical problem of the present invention, the present invention discloses a kind of TV program switching method, described television set adopts at least two demultiplexers, when a demultiplexer that is in the work at present state provided the data of current program, other the demultiplexer that is in idle condition changed the platform prediction algorithm according to one and sets up data channel for the next target program that may switch; Change platform when instruction when television set receives, the demultiplexer that is in the work at present state switches to idle condition, and the demultiplexer of setting up target program data passage switches to the work at present state, for television set provides current program data.
Compared with prior art, because the present invention adopts a plurality of DEMUX that program is provided in turn and prepares the data channel of next program according to the algorithm of prediction, when the user changes platform, in most cases user's target program that will switch predicted to and prepared to receive by idle DEMUX, therefore be only need switch to corresponding D EMUX to get final product changing platform, thereby omitted DEMUX and prepared the required time of data channel, saved the time of changing platform greatly, improved the speed of changing platform.

Embodiment
The present invention adopts many DEMUX to change the method for platform.Present many chip platforms all provide the support of plural DEMUX, and in that the user is actual when watching program, only use one of them usually, and other DEMUX resource is in idle condition.Therefore, adopt channel switching method of the present invention can not increase extra hardware cost.
TV program switching method principle of the present invention is as follows: when the DEMUX that is in the work at present state provides the data of current program, other the DEMUX that is in idle condition changes the platform prediction algorithm according to one and sets up data channel for the next target program that may switch, and prepares to receive the data of the next target program that may switch; Change platform when instruction when the user sends, prepare the target program that receives if the target program that the user will switch to just is a DEMUX among other DEMUX according to changing the platform prediction algorithm, then direct switch data passage adopts this DEMUX that current program data is provided; Simultaneously, make the DEMUX that is switched change the data that the platform prediction algorithm prepares to receive the next target program that may switch according to described.If the target program that the user will switch to does not have predicted algorithm predicts to arrive, then still adopt current DEMUX to prepare the data channel of target program again.Described prediction algorithm can be according to user's the use habit predictive user program that switches of most probable next time, change platform in proper order and check that the program of oneself liking formulates prediction algorithm such as being accustomed to employing, perhaps in a certain class program, change platform and formulate prediction algorithm according to user's custom according to the user.
Fig. 1 is the schematic diagram of TV program switching method one execution mode of the present invention.Sign program 1, program 2, program n are the programs that chooses by prediction algorithm among the figure, and wherein, what solid line pointed to is current in progress program, and what dotted line pointed to is the program that can switch fast.Left side DEMUX1 provides data for current program, and idle DEMUX 2, DEMUX N is that subsequent program is prepared data.If at this moment change platform, need change to program 2 from program 1, then becoming the right DEMUX 2 provides data for current program, because DEMUX 2 has been that ready state (is the foundation that DEMUX finishes data channel, can accomplish to accept at any time the state of data), so the data of program 2 can get access to very soon, offer subsequent applications then, so program just can be play apace; Meanwhile, the right DEMUX1 is used to prepare new program K again, and this process is that background task is finished, and the platform that changes that can not have influence on the user moves.So operation can be saved the time of changing platform greatly.
The present invention is not limit by above-mentioned execution mode, the DEMUX that adopts as television set can only be two, adopt this moment two DEMUX that program is provided in turn and prepare the data channel of next program according to prediction algorithm, and the DEMUX that adopts is many more, predictable target program is many more, and prediction accuracy is just high more.
In sum, in program switching method of the present invention, because a plurality of DEMUX of employing provide program in turn and prepare the data channel of next program according to the algorithm of prediction, when the user changes platform, in most cases user's target program that will switch predicted to and prepared to receive by idle DEMUX, therefore be only need switch to corresponding D EMUX to get final product changing platform, thereby omitted DEMUX and prepared the required time of data channel, save the time of changing platform greatly, improved the platform speed of changing.
