Embodiment
The invention provides a kind of channel associated data information display terminal, be applied to the multimedia broadcasting field, when the channel associated data information of described terminal parses in the data segment of multiplexed sub frame, this terminal is used for pointing out the user of this terminal to watch by the mode of display button information; After the user pressed corresponding function button, this terminal showed described channel associated data information.
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is described in detail.
As shown in Figure 1, be the structural representation of a kind of channel associated data information display terminal of the embodiment of the invention, this terminal comprises demultiplexing module, cache module, button prompting module, display module and data term of validity judge module, wherein:
Demultiplexing module, the multiplexed frame that is used for described terminal is received carries out demultiplexing, solves multiplexed sub frame, and judges in the data segment of multiplexed sub frame whether comprise channel associated data information, if comprise then send it to described cache module;
Cache module is used to receive the channel associated data information that described demultiplexing module is exported, and it is carried out buffer memory, and notify described button prompting module; Also be used to set the buffer memory term of validity of described channel associated data information; Also be used for not deleting at the channel associated data information of the buffer memory term of validity;
The button prompting module is used to notify described display module to point out the user of this terminal to watch described channel associated data information by the mode of display button information; Also be used to notify described display module to point out described user to stop to show described channel associated data information by the mode of display button information;
Display module is used to show described button prompting information; After the user presses the predefined function button that is used to show, also be used to show described channel associated data information; Also be used to show the described button prompting information that stops to show; After the user presses the predefined function button that is used to stop to show, also be used to stop to show described channel associated data information; Also be used for the display frame of described terminal is divided into two districts: a district is a broadcast area, is used to the program that continues to display the play, and another district is the channel associated data information viewing area, is used to show described channel associated data information;
Data term of validity judge module, be used for judging whether the channel associated data information that is stored in described cache module is in the buffer memory term of validity: if in the buffer memory term of validity, then after the user pressed the predefined function button that is used to show, this terminal showed described channel associated data information; If not in the buffer memory term of validity, then notify the channel associated data information of described cache module deletion buffer memory, and notify described button prompting module to stop to show described button prompting information.
Channel associated data information display packing of the present invention is that terminal is resolved multiplexed sub frame during the play multimedia program, the judgment data section indicates whether to be 1, if be 1, show that there is channel associated data information in the data segment of this subframe, then these channel associated data informations are carried out buffer memory.Simultaneously, on screen, provide button prompting, for example " the instant report ".If the user presses corresponding function key, for example right soft key, then at the data message of the corresponding regional display buffer of screen, the audio/video program of screen continues to play at this moment certainly.When showing channel associated data information, corresponding button prompting and keypress function carry out switch and switch, and promptly button prompting becomes " closing ", and corresponding right soft key becomes and stops the video data function of information display.If the user by the bottom right soft key, then stops showing with circuit-switched data on the display screen once more.That is to say that the user can manually control the demonstration of opening or stopping to show channel associated data information, the convenient switching.
As shown in Figure 2, it is the schematic diagram that a kind of channel associated data information display terminal of application example of the present invention shows channel associated data information, 201 are the common mode of watching among the figure, bottom " left soft key " and " right soft key " is the function key in the keyboard of terminal among the figure, and do not have channel associated data information in the multiplexed sub frame this moment; 202 is the button prompting that terminal provides when the data segment in the multiplexed sub frame comprises channel associated data information (for " the instant report "); 203 for (for example pressing corresponding function button as the user, right soft key) display frame after, promptly stack shows channel associated data information on the audio/video program broadcasting pictures, and button prompting has carried out switching (switching to " closing ") simultaneously, and corresponding right soft key also becomes closes Presentation Function.
As shown in Figure 3, be the process chart of a kind of channel associated data information display packing of application example of the present invention, comprise the steps:
For example, can judge the data segment indication field in the multiplexed sub frame head, when this field is 1, comprise channel associated data information in the expression data segment.
Because terminal shows channel associated data information in the play multimedia program, therefore can be divided into two districts to the display frame of terminal, a district is a broadcast area, the program that continues to display the play; Another district is the data message viewing area, shows with circuit-switched data.
Certainly, the broadcasting pictures that also channel associated data information can be added to shows together; In this case, " channel associated data information viewing area " broadcasting pictures that is added to shows that together " channel associated data information viewing area " can be in translucent.
Whether by the foregoing description, terminal can receive channel associated data information when playing audio/video programs, after receiving channel associated data information, shown by user's decision, and can show and stop to switch at any time under the show state.Therefore the opportunity that different users can check channel associated data information according to own needs selection, skip as not wanting to be disturbed then, do not influence the appreciation of audio/video program, strengthened user's experience.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof, those skilled in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the claim of invention.
