Abstract
The invention provides a mosaic program navigating method, which comprises the following steps: adopting a mosaic synthesizer to synthesize sub unit programs integrating with corresponded private information, uniformly processing private information in the sub unit programs, packing program flow containing private information to form mosaic program flow after the mosaic synthesizer synthesizes sub unit programs, and sending to a set up box to analyze. The mosaic program navigating method overcomes the problems that a data organization mode in the prior art requires to edit information which is to be sent in advance, since the quantity of sub units contained in mosaic programs is not assured, the program arraying sequence in the sub unit is not assured, although information related with programs of each sub unit is fixed, private information is required to edit once the sequence is changed or the number of the unit is changed, and working capacity for organizing private information is bigger.
Description
Technical field
The present invention relates to field of broadcast televisions, in particular to a kind of mosaic program navigating method.
Background technology
Along with popularizing of Digital Television, set-top box is come into huge numbers of families.Digital television program is compared with traditional program, and an important progress is exactly the digital data transmission mode that adopts in digital television program, can carry a large amount of information and control command in the transmission program.
Mosaic (mosaic) navigation program is a kind of in the digital television application, and its form of expression is synthesized in a program for the picture with a few cover to tens programs, and can be by set-top box to subelement display message and controlling respectively.Since in the screen displayed that originally only shows a program multiple programs, so the amount of information that comprises is bigger, the space of having brought more adding private service to use for digital-TV operator is so the application mode and the displaying contents organizational form of mosaic navigation program have all obtained fast development.
In realizing process of the present invention, the inventor finds that data organization mode of the prior art requires to edit in advance the information that will send, because the subelement quantity that comprises in the mosaic navigation program is uncertain, and the program in the subelement puts in order also uncertain, though each is fixed as the relevant information of the program of subelement, but, cause and organize the workload of private information bigger in case order changes or the unit number changes and will edit private information again.
Summary of the invention
The present invention aims to provide a kind of mosaic program navigating method, can solve data organization mode of the prior art and require to edit in advance the information that will send, because the subelement quantity that comprises in the mosaic navigation program is uncertain, and the program in the subelement puts in order also uncertain, though each is fixed as the relevant information of the program of subelement, but, cause the bigger problem of workload of organizing private information in case order changes or the unit number changes and will edit private information again.
In an embodiment of the present invention, provide a kind of mosaic program navigating method, may further comprise the steps:
Adopt the mosaic synthesizer to have the subelement of corresponding private information program to synthesize to incorporating;
Private information in the subelement program is unified to handle; And
After the mosaic synthesizer was synthetic to the subelement program, the program stream packing formation mosaic program stream that will include private information sent to set-top box and resolves.
In the above-described embodiments, by adopting the mosaic synthesizer to have the subelement of corresponding private information program to synthesize to incorporating, make the subelement program before entering the mosaic synthesizer, just have private information, and then the private information in the subelement program unified to handle, do not need to edit private information separately for mosaic navigation program, when the quantity of subelement program or position changed, the dynamic characteristic of the private information generative process of mosaic navigation program made the private information of mosaic navigation program not need to update.Overcome data organization mode of the prior art and required to edit in advance the information that will send, because the subelement quantity that comprises in the mosaic program is uncertain, and the program in the subelement puts in order also uncertain, though each is fixed as the relevant information of the program of subelement, but, cause the bigger problem of workload of organizing private information in case order changes or the unit number changes and will edit private information again.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 shows a kind of according to an embodiment of the invention mosaic program navigating method flow chart.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 1 shows a kind of according to an embodiment of the invention mosaic program navigating method flow chart, may further comprise the steps:
S102 adopts the mosaic synthesizer to have the subelement of corresponding private information program to synthesize to incorporating;
S104 unifies to handle to the private information in the subelement program; And
S106, after the mosaic synthesizer was synthetic to the subelement program, the program stream packing formation mosaic program stream that will include private information sent to set-top box and resolves.
In the present embodiment, by adopting the mosaic synthesizer to have the subelement of corresponding private information program to synthesize to incorporating, make the subelement program before entering the mosaic synthesizer, just have private information, and then the private information in the subelement program unified to handle, do not need to edit private information separately for mosaic navigation program, when the quantity of subelement program or position change, the dynamic characteristic of the private information generative process of mosaic navigation program makes the private information of mosaic navigation program not need to update, overcome data organization mode of the prior art and required to edit in advance the information that will send, because the subelement quantity that comprises in the mosaic navigation program is uncertain, and the program in the subelement puts in order also uncertain, though each is fixed as the relevant information of the program of subelement, but, cause the bigger problem of workload of organizing private information in case order changes or the unit number changes and will edit private information again.
Preferably, in above-mentioned mosaic program navigating method, when the subelement program is in real time during stream, adopting the mosaic synthesizer to have the subelement of corresponding private information program also to comprise before synthesizing private information is incorporated corresponding subelement program to incorporating.
