The method that shows electronic program guide information
Technical field
The present invention relates to the digital television techniques field, especially relate to the method for a kind of demonstration electronic program guide information (EPG) information.
Background technology
Develop rapidly along with electronic technology and video transmission technologies, and the continuous maturation of digital television techniques, set-top box has been come into huge numbers of families, this makes the user can better enjoy the good service that Digital Television is brought to life, because TV programme also increases in a large number, this has brought inconvenience with regard to giving the user when selecting to check channel and program simultaneously.Present solution is to adopt Digital Television to transmit the electronic program guide information technology, as shown in Figure 3, these information are to search out electronic program guide information to sort according to service and time, and be presented in the tabulation of interface, the user can check the performance guide information of this channel by selecting channel 13, these performance guide informations comprise programme information 14, and the reproduction time 15 of program is watched the in progress program of this channel at video window 12 simultaneously.Though this checks that to the user program has brought convenience, the program of at every turn checking other channel all can change the program that video window 12 is play, and is cost to withdraw from played in full screen, and this just gives searching in the program process the user and has brought inconvenience.And develop today rapidly at digital television techniques, when not only will guarantee in electronic program guide information to provide comprehensive program to introduce to the user, also will for the user provide a kind of convenient, check the method for program guide efficiently.
The existing method that electronic program guide of digital television information is shown, all be to show videotex on (OSD) bed boundary at program, carry out the arrangement of electronic program guide information data with services/channels and time, this method has not only influenced user's video-see, although tend to design on the electronic program guide information interface small video window is arranged, but as digital TV video frequency is the main body of function, so this is a function shortcoming; And because the electronic program guide information data volume is very big, and the number of words and the amount of information that can show on the electronic program guide information interface are limited, the user then needs a large amount of interface page turnings and other operation if check complete information.Above-mentioned drawbacks limit in the DVB business about the expression effect of this function of electronic program guide information.
Summary of the invention
The objective of the invention is to, a kind of method that shows electronic program guide information is provided, make the user under the situation that does not influence the video main body, can view more video information.
For achieving the above object, the present invention adopts following technical scheme:
A kind of method that shows electronic program guide information, the transmission code stream that set-top box is obtained converts the electronic program guide information caption information to and sends to the display device demonstration, may further comprise the steps:
(1) by set-top box the electronic program guide information data is searched in real time and stored;
(2) described set-top box becomes caption information with the electronic program guide information data transaction of described storage;
(3) be set to translucent by the described caption information of image effect adjusting module in the described set-top box;
(4) described set-top box sends to the display device demonstration with caption information.
Adopting technical scheme of the present invention not need to withdraw from played in full screen can enter the electronic program guide information interface and check electronic program guide information, the user can be when normally watching program, check programme information, make and check that programme information is convenient, quick, satisfied the high-quality demand of user greatly.

Fig. 2 is the schematic diagram of multirow caption information of the present invention;
Fig. 3 is the schematic diagram of prior art caption information of the present invention;
Fig. 4 is a flow chart of the present invention.
The realization of the object of the invention, functional characteristics and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 4, a kind of method that shows electronic program guide information may further comprise the steps:
(1) by the search module in the set-top box transmission code stream is searched for, obtain the data of electronic program guide information and it is kept in the memory module of described set-top box by resolving code stream, wherein this memory module can be preserved information for a long time, and the storage medium of this memory module is a non-volatile memory medium;
(2) convert the data of the electronic program guide information of described storage the caption information of single file or multirow to by graphical interface of user, and constantly refresh described electronic program guide information image to obtain the effect of roll titles by the timer in the described set-top box; Wherein said caption information can a channel of single display electronic program guide information, also can be simultaneously the electronic program guide information data transaction of a plurality of channels be become same caption information; Perhaps realize the electronic program guide information on this channel same day or many days.
(3) utilize image effect adjusting module in the set-top box, the information of described captions state is adjusted into translucent, on view screen, show simultaneously.
Whole electronic program guide information procedure for displaying is:
When played in full screen program 1, by set-top box the data of electronic program guide information are searched for and stored, when the user need check electronic program guide information, only need by clicking or select shortcut can start this program; At this moment, demonstrate "Yes" or "No" shows electronic program guide information with the single file captions selection on the television screen, if selection "Yes", then below screen, will show electronic program guide information 2 with the translucent captions of single file roll mode from right to left, if the selection "No" is then right-hand with the translucent captions of multirow roll mode demonstration electronic program guide information 7 from bottom to top at screen; When not needing to check, can close this caption information by clicking or select shortcut.
Wherein, described single file captions electronic program guide information 2 can comprise Pgmtime 3 and programme information 4; It is little that this method takies screen space, provides this channel program guide information when the user normally watches not influencing.
Described multirow captions electronic program guide information 7 comprises a plurality of Pgmtimes 9 and the programme information 10 of current channel, and demonstrate current date 8 simultaneously, this method can once show more performance guide information, and can show current date and week.
Adopting technical scheme of the present invention not need to withdraw from played in full screen can enter the electronic program guide information interface and check electronic program guide information, the user can be when normally watching program, check programme information, make and check that programme information is convenient, quick, satisfied the high-quality demand of user greatly.
The above only is the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
