The navigation method of the real-time video content comprises the steps of obtaining a video stream of a program signal source in real time, obtaining configuration parameters of a navigation image input by a user, carrying out coding on the video stream, obtained in real time, of the program signal source by the utilization of the configuration parameters of the navigation image according to classified information of preset programs, and generating a real-time navigation program current. The navigation method and device of the real-time video content have the advantages that the user can select the programs through the dynamic multiple images, live telecast content can be classified automatically, and therefore the butt joint between the device and a terminal is omitted; in addition, due to the fact that only videos instead of voice frequency are transmitted through navigation, and the band width is saved largely.
Description
Technical field
The present invention relates to multimedia technology field, relate in particular to a kind of air navigation aid and device of real-time video content.
Background technology
Digital Television and IPTV(IPTV), mobile TV, OTT(Over The Top, refers to by the Internet and provides various application services to user) fast development, make video content to arrive fast user side by multiple channel.Cable TV is no longer the unique selection of user, and user can select the mode of oneself being familiar with most convenient most to view and admire video content.Operators have started content-based fighting with a weapon, so whichever operator all can provide the live on-demand content that also has magnanimity of hundreds of channels to user.In the face of vast as the open sea content, in the middle of how obtaining fast the content of oneself liking rather than the most of the time being used in to eternal selecting, become a real problem.For the program request of video, because can classify in advance on backstage, therefore realized more for a long time classification program request, and lack effective mode for direct broadcast band, classify.
No matter be cable TV or the Video service of IPTV and OTT mode at present, for live content, all there is no effective navigation Service, traditional EPG(Electronic Program Guide, electric program menu) navigation is owing to only having picture and text not directly perceived, and the switching from programme content to EPG has some setbacks, user experiences very poor, causes its utilization rate very low.Also have traditional many picture navigation system, due to the exploitation of docking relating to Set Top Box, at cable TV network and new media industry, all effectively do not promoted, present user still will be ceaselessly be traveled through and be selected the program that oneself will see by zapping.
In a kind of prior art, EPG program navigating is that current cable or IPTV are used maximum navigation Service.In fact EPG is exactly a gate system of IPTV.The interface of EPG system and Web classes of pages seemingly, the assembly of directly clicking while generally all providing all kinds of menus, button, link etc. to select program for user on EPG interface; On the interface of EPG, also can comprise all kinds of dynamic or static content of multimedia of browsing for user, mainly the mode with picture and text provides programme, user need to click and enter EPG picture and watch in Set Top Box, returns direct broadcast band afterwards by exiting EPG system.The main shortcoming existing below of EPG system navigation: 1) only have the TV guide of character property, content is not directly perceived less; 2) need to from live, exit the picture that enters EPG, finish watching to exit get back to live, the slow complicated operation of speed; 3) because EPG content is to be blended in program stream, enter EGP picture and will wait for that EPG content reception is complete and could show, slow; 4) EPG content is because be human-edited, often wrong, or sometimes there is no EPG information; 5) EPG content is character property, because picture area is limited, need to ceaselessly stir and check, sluggish is used inconvenience.
Also have a kind of prior art, traditional mosaic navigation system is by the live signal recompile of multichannel, produces the navigation interface that a plurality of little live pictures represent simultaneously, and the resource that such a picture takies a channel is transmitted.Thereby Set Top Box can be switched by remote controller focus and selects the channel of appointment and enter to watch in this picture.But the problem that traditional mosaic navigation system exists is: 1) navigation system need to be carried out integratedly with the terminal such as Set Top Box, disposes comparatively complicated certain risk that exists; 2) only provide several navigation channels, user still need to find the program that will see in a large amount of programs, except picture without other guidings; 3) navigation channel takies larger bandwidth with a plurality of tracks.
