Background technique
DTV and IPTV, mobile TV, the fast development of OTT allow video content to pass through multiple channelQuickly reach user terminal.Cable television is no longer that user uniquely selects, and user can choose oneself most familiar with most convenientMode watches video content.Operators have started fighting with a weapon based on content, and then whichever operator can all mention to userFor the on-demand content of the live streaming also magnanimity of hundreds of channels.In face of vast as the open sea content, how to be quickly obtained and oneself likeContent rather than the most of the time is used in eternal select and becomes a real problem.For the point of videoIt is relatively more early to be achieved that classification program request because can classify in advance from the background for broadcasting, and direct broadcast band is lackedLack effective mode to classify.
The current either Video service of cable television or IPTV and OTT mode, does not all there is live contentThe navigation Service of effect, traditional EPG navigation is not intuitive due to there was only picture and text, and the switching from programme content to EPG has some setbacksUser experience is very poor to cause its utilization rate very low.
There are also traditional more picture navigation systems, due to being related to docking exploitation with set-top box, in cable TV networkIt is not all promoted effectively with new media industry, present user still will ceaselessly traverse selection oneself by zappingThe program to be seen.
EPG program navigating is current cable or the most commonly used navigation Service of IPTV.EPG is actually IPTV'sOne gate system.The interface of EPG system is similar with Web page, and all kinds of menus, button, chain are generally all provided on EPG interfaceIt connects etc. and to select the component clicked directly on when program for user；It also may include on the interface of EPG all kinds of for the dynamic of user's browsingThe multimedia content of state or static state, mainly provides program listing, user needs to click to enter EPG on the set-top box in a manner of picture and textPicture is watched, and returns direct broadcast band by releasing EPG system later.
EPG system navigation is primarily present following disadvantage:
1) there was only the TV guide of character property, content is not few intuitive；
2) it needs to exit into the picture of EPG from live streaming, finishes watching to exit and return to live streaming, speed is complicated for operation slowly；
3) since EPG content is blended in program stream, to wait EPG content to receive into EGP picture could be shownShow, slowly；
4) EPG content is often wrong because being human-edited, or sometimes without EPG information；
5) EPG content is character property, since picture area is limited, needs ceaselessly to stir and check, reacts and slowly usesIt is inconvenient.
As shown in Figure 1, traditional mosaic navigation system is to recompile the live signal of multichannel, production one is multipleThe navigation interface that small live streaming picture shows simultaneously, the resource that such a picture occupies a channel are transmitted.Set-top boxFocus can be switched in this picture by remote controler to the specified channel of selection and enter viewing.
Traditional mosaic navigation system the problem is that:
1) navigation system needs are integrated with terminals such as set-top boxes, dispose that complex there are certain risks；
2) several pilot channels are provided solely for, user still needs to find the program to be seen in a large amount of program, removes pictureWithout other guidings outside face；
3) pilot channel occupies large bandwidth with multiple tracks.
