For the purpose of clear, the figure that these accompanying drawings are schematically and simplify, they have only provided for understanding the necessary details of the present invention, and omit other details.In institute's drawings attached, identical Reference numeral and title are used in reference to same or corresponding part.
Through detailed description given below, the further scope of application of the present invention will be obvious.Yet; Be to be understood that; When describing in detail and object lesson shows the preferred embodiment of the present invention, they are merely illustration purpose and provide, because; For a person skilled in the art, be described in detail in through these that to make variations and modifications in spirit and scope of the invention be conspicuous.
Embodiment
Fig. 1 shows the time division type glasses that utilize according to the present invention and realizes that many video contents do not disturb the sketch map of the method for watching mutually.When the user had multipath demonstration synchronously to need, the user can open the synchronous Presentation Function of multichannel of television set.The user sets the corresponding time division type glasses of number of vias, the pairing displaying contents of each path and each path that need to show synchronously through television set and numbers.Television set shows that output after receiving unlatching information, switches to the synchronous display mode of multipath.Multipath video source such as A video source and B video source to user's setting; It is behind A picture and the B picture its interleave that carries out the frame picture to be handled that display module obtains the individual channel picture; The interleave processing can be the interspersed processing of frame at interval of simple equal portions, also can be uncertain or interspersed processing of the moment of variation.Signal source can be different tuners different channel picture, different digital television content, connect input signal source or the webpage among the smartTV behind other equipment.
In a preferred embodiment; Adopted the interspersed mode of equal portions at interval, per second alternates to A picture and B picture, just 1 frame A picture heel, 1 frame B picture; Picture by each path 60 frame of per second originally; Generate the per second display frame of totally 120 frames, outputed to display to mixed 120 frame picture unifications then, and write down going out now of individual channel frame picture.
The wired or wireless mode that goes out to utilize now existing maturation of individual channel frame picture is sent to the time division type glasses.A path time division type glasses are after receiving the synchronization point signal, and the frame that only occurs at corresponding A path frame picture is opened the glasses shutter constantly, all close the glasses shutter constantly at other.Like this, the user is after wearing these A path glasses, and the television image content of watching from glasses is the content of corresponding A path picture.And the spectators that wear the corresponding B path time division type glasses of B path, the TV set image of seeing but is the picture of B path.Auxiliary earphone on the glasses in addition; Difference transmission to different path sound; Spectators can enjoy after wearing the specific passageways glasses content of TV program that should path, thereby make the programme content that a plurality of spectators can use a television set to watch liking separately simultaneously.
Fig. 2 shows the time division type glasses that utilize according to the present invention and realizes that many video contents do not disturb the block diagram of the system of watching mutually.Shown in figure; In the multipath display device; When receiver module receives the instruction of multipath demonstration synchronously; The multipath display module is responsible for carrying out interleave to the different programme contents from unlike signal source A video source and B video source and is handled, and generates final demonstration output picture and sends to display output, writes down the synchronization point of different path pictures simultaneously and is sent to shutter control and transport module.Fast gate control and transport module are responsible for sending the corresponding synchronization point of each path of multipath display module through wired or wireless mode.The corresponding time division type glasses synchronization control module of different paths receives the signal of fast gate control and transport module transmission, and according to synchronization point, only opens glasses in the moment that corresponding path picture shows, and close glasses constantly at other.Thereby reach the effect of only seeing corresponding path picture.
Fig. 3 shows the polarising glass that utilizes according to the present invention and realizes that many video contents do not disturb the sketch map of the method for watching mutually.When the user had multipath demonstration synchronously to need, the user can open the synchronous Presentation Function of multichannel of television set.The user sets through television set needs the pairing displaying contents of two paths of demonstration synchronously.Television set shows that output after receiving unlatching information, switches to the synchronous display mode of multipath.To A video source and the B video source that the user sets, display module is exported mutually perpendicular complete polarised light to different paths after obtaining the corresponding picture of two paths.Make the polarization direction of polarized lenses of a pair of polarising glass identical with the polarization direction of a path respectively; Polarising glass only sees through corresponding light; Thereby the spectators that wear A path glasses can only see the picture of A video source; The spectators that wear B path glasses can only see the picture of B video source, and then reach two spectators and use a television set to watch the effect of the program of liking separately simultaneously.In the above-described embodiments, export mutually perpendicular complete polarised light to different paths and comprise the approximately perpendicular complete polarised light of output.
Fig. 4 shows the polarising glass that utilizes according to the present invention and realizes that many video contents do not disturb the block diagram of the system of watching mutually.Shown in figure; In the multipath display device; When receiver module received the instruction of multipath demonstration synchronously, the multipath display module was responsible for to the different programs from unlike signal source A video source and B video source, and control shows that projecting mutually perpendicular complete polarised light exports; Be complete polarised light output of A picture and the complete polarised light output of B picture, then complete polarised light output sent to the two-way polarizer display.The corresponding polarising glass of different paths is A path polarising glass and B path polarising glass; Use respectively and A picture or the same polarized lenses of B picture polarised light output angle; Corresponding polarized lenses polarization direction is identical with the polarization direction of this path; Glasses only see through corresponding light, thereby reach the effect of only seeing corresponding path picture.
Preferred embodiments more of the present invention have been described above, but what should stress is that the present invention does not receive the restriction of these embodiment, but the alternate manner in the theme that can the present invention limits is realized.
