Fig. 1 shows the TV programme browsing method realization flow that the embodiment of the invention provides, and its detailed step is as described below:
In step S101, open mosaic page and browse the TV programme function.
In embodiments of the present invention, the user opens mosaic page and browses the TV Festival purpose function and can finish by the specific keys on the remote controller, also can finish by the relevant option of menu.
In step S102, selected user need to carry out the frequency of program browsing, locks.
In embodiments of the present invention, the user can carry out the selected of frequency by manual input or according to the selection mode that receiving terminal for digital television provides.
In step S103, judge whether success of locked frequency point, be execution in step S104 then, browse the TV programme of watching before the TV programme function otherwise continue to play opening mosaic page, or, forward other frequencies to, and return step S102.
In step S104, resolve the program number information of the program frequency point data flow of locking.
In embodiments of the present invention, the program number information of this locking is the tricks of the TV programme that comprises of current frequency.
In step S105, according to program number information among the step S104, generate the mosaic page that comprises the mosaic unit lattice.
In step S106, the mosaic unit lattice that are controlled at mosaic page are play the video data of the corresponding program of mosaic unit lattice, and the mosaic unit lattice of controlling simultaneously the screen focus place are play the voice data of the corresponding program of mosaic unit lattice.
As one embodiment of the present of invention, under the mosaic page state, audio, video data is carried out following concrete processing:
1. obtain the programme information of mosaic page from the described program frequency point data flow of resolving, programme information comprises following content: serivceId, video pid and audio pid at least.
In this embodiment, behind the locking program frequency point, when from the corresponding data flow of this frequency, resolving program number information, also from data flow corresponding to this frequency, obtain the programme information of mosaic page.
2. each the mosaic unit lattice in the mosaic page are proceeded as follows:
If be not 0 2.1 the corresponding program of these mosaic unit lattice is TV type and video pid, then according to the video pid of this programme information, in the mosaic unit lattice at this program place, play the corresponding video of this program;
2.2 if the corresponding program of these mosaic unit lattice is the Radio type, perhaps but TV type video pid is 0 (without video data), and then this program of prompting user is that radio or prompting user are without video in the corresponding mosaic unit lattice of program;
2.3 working as the corresponding program of cell is the Radio type, but perhaps TV type video pid is 0 o'clock, according to the audio pid of this programme information, and the voice data of the mosaic unit lattice at view screen focus place.
When mosaic page changes, then repeat above-mentioned steps 1 and 2.
In step S107, receive the key command of user's input.
In embodiments of the present invention, user's button is the button on remote controller or the receiving terminal for digital television front panel, and the user sends key command, for example set direction key, ESC Escape and acknowledgement key by this button.
In step S108, mosaic page is carried out the action event corresponding with key command.
In embodiments of the present invention, the action event corresponding with key command comprise withdraw from mosaic page, at mosaic page conversion focus, the corresponding program of focus cell that is transformed into other mosaic page and plays mosaic page.
When the user presses ESC Escape, continue to play and to enter the program of playing when this mosaic page is browsed before the purpose function of TV Festival;
When the user presses the choice direction key, at current mosaic page internal conversion screen focus, change focus, cut off simultaneously the audio frequency of old focus, play the audio frequency of new focus;
When the user carried out definite key operation to the program of selected focus cell, the program that the focusing cell is corresponding was play, and withdraws from this mosaic page and browses the TV Festival purpose function, the program that played in full screen focus cell is corresponding;
When the user by page-turning function or when pressing successively the set direction key mosaic page being turned to the mosaic page of the other mosaic page of current frequency or other frequency, focus is transferred in the mosaic page equally.
As one embodiment of the present of invention, Fig. 2 shows the generation method realization flow of the mosaic page that the embodiment of the invention provides, and its detailed step is as described below:
