Embodiment
The technical scheme that provides of the present invention is: when the user watched TV programme, television system was obtained the EPG information of entrained each programs of current frequency on the backstage, and leaves in the Installed System Memory; When the user starts the EPG function, the EPG information that system directly reads current frequency in the internal memory is shown to the user, simultaneously browse the program mode according to the user, judge that the user will watch the sequencing of EPG information, obtain the EPG information of corresponding frequency according to this sequencing segmentation, when the user selects to watch the EPG information of next frequency, can access these EPG information immediately and give the user like this, the EPG information that can provide the user fast and be concerned about.
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
After the digital television system start, parameter locked frequency point and displaying video programs before can shutting down according to the user also can at first lock a frequency when user is switched program.At this moment no matter whether the user uses EPG, television operator is play the EPG information of each entrained programs of this frequency usually at current frequency, television set receives and stores above-mentioned EPG information, in the technical scheme provided by the invention, system will obtain the EPG information of current frequency automatically and be kept in the internal memory on the backstage.If the user starts the EPG function, then system shows the EPG information of current each programs of frequency according to the order of UI (User Interface user interface) display algorithm.
Because a digital frequency comprises multiple programs, also can arrange multiple programs simultaneously on the screen.Under normal conditions, filtered EPG information when system forwards this frequency in advance, when the user entered the EPG menu, system will list the EPG information of contained each programs of this frequency earlier.
In specific embodiments of the invention, system determines putting in order of current each programs of frequency according to current program at the relative position of current TS stream.Its basic principle is: if described current program is in the first half of described current TS stream, then described current program is arranged in first, other programs are arranged in after the described current program according to the mode that increases progressively; If described current program is in the latter half of described current TS stream, then described current program is arranged in last position, other programs are arranged in before the described current program according to the mode that increases progressively.
Specify as follows: suppose to comprise the m programs in the TS stream, the current program number of watching is n, and the once displayable number of programs of video screen is L, and i is the position that program shows on screen, CH (i) is at i position display program number, and q is for calculating the intermediate variable that uses.With P is zequin, for horizontal UI, along with increasing progressively of i arranged program from left to right one by one, as shown in Figure 1; For the UI of vertical arrangement, along with increasing progressively of i arranged program from the top down, as shown in Figure 2.
The flow process of each programs of system-computed ordering is at first calculated q=m-n as shown in Figure 3, if q 〉=n, perhaps n＞q＞L, algorithm is for (i=0; I++; { the CH (i)=n+i} of i＜L); When i=0, CH (0)=n, the i.e. program that is n at first position display program number.
If q＜n, and q＜L, algorithm are for (i=0; I++; { the CH (L-i)=m-i} of i＜L); When i=0, CH (L)=n, promptly in the end position L display program number is the program of n.
For example, a TS stream has 8 programs (m=8), and screen once can show 4 programs (L=4), supposes that the current program of watching is 3 (n=3), q=m-n (q=5) then, and 5 greater than 3, belong to the situation of q＞n; In this case program 3 is arranged in first position, the program of back increases progressively arrangement: CH (0)=3, CH (1)=4.....
Suppose that the current program of watching is program 6 (n=6), q=m-n (q=2) belongs to the situation of q＜n (2＜6); In this case program 6 is arranged in last position of tabulation, the program of front arrangement: the CH (4)=6 that successively decreases, CH (3)=5.....
After system determines putting in order of current each programs of frequency according to aforementioned algorithm, will be shown to the user according to each programs of the current frequency of determined sequence arrangement.The program mode is simultaneously browsed according to the user by system, judges that the user will watch the sequencing of EPG information, obtains the EPG information of corresponding frequency according to this sequencing segmentation, below specifies:
As depicted in figs. 1 and 2, the arrangement of the programme information of a certain frequency in EPG has dual mode usually, and a kind of is that the mode that increases progressively according to program number is horizontal; A kind of is the mode vertical arrangement that increases progressively according to program number.Below be that example describes with the horizontal EPG of Fig. 1, operate in the process of EPG the user, two kinds of browsing methods can be arranged: turn right from current location and switch the program of being watched, perhaps turn left and switch the program of being watched from current location.And normally from left to right program number increase progressively, so system can judge that the user browse the mode of EPG by the Changing Pattern by program number, thereby adopts different filter methods.For the EPG of vertical arrangement, its principle is identical, and this does not give unnecessary details.
If the user browses EPG information in the mode that program number increases progressively, the frequency that needs to filter below then is exactly the next frequency F+1 of current frequency (being assumed to be F); Otherwise if the mode viewing information that the user successively decreases with program number, then a last frequency F-1 of current frequency filters in elder generation.
Behind the frequency of determining to prepare to filter by above method, system reads the program data that NVRAM stores, obtain data such as the TS ID (Transport Stream Identify. transport stream identification number) of the stream of TS on this frequency and program ID, whether the EPG information of inquiring about this frequency to epg database according to these conditions obtains then.If obtain, then system is according to the top next frequency that does not have EPG information of method inquiry; If do not obtain, then system obtains the EPG information of this frequency, all obtains up to the EPG information of all frequencies of this direction.
Embodiment of the invention flow chart specifically comprises following step as shown in Figure 4:
1, user's TV reception, system obtains the EPG information of current frequency automatically and is kept in the internal memory on the backstage;
2, the user starts the EPG function, and system determines putting in order of current each programs of frequency according to current program at the relative position of current TS stream, shows the EPG information of each programs of current channel in regular turn;
Does 3, the user still browse EPG information in the mode that program number successively decreases in the mode that program number increases progressively? if, then change step 4, otherwise change step 5 in the mode that program number increases progressively;
4,, obtain the EPG information and the preservation of current frequency all frequencies afterwards in regular turn from the next frequency of current frequency;
5,, obtain the programme information and the preservation of current frequency all frequencies before in regular turn from a last frequency of current frequency.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
