The apparatus structure schematic diagram that Fig. 2 provides for the embodiment of the present invention;
The application illustration that Fig. 3 provides for the embodiment of the present invention.
The realization of the object of the invention, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The embodiment of the present invention provides a kind of multichannel same screen device, and this multichannel can be independently equipment with screen device, also can be integrated in other equipment, as router, various smart machines etc., as shown in Figure 1, comprise:
Arm processor and WiFi receiver module, described WiFi receiver module connects described arm processor, described WiFi receiver module is provided with the interface for connecting video-unit, described WiFi receiver module receives the dissimilar video data coming from video-unit, receive the dissimilar video data coming from video-unit, described dissimilar video data is identified, then described dissimilar video data is broken, and according to the result identified, the video data of correspondence is sent to arm processor;
Video data after partition is carried out format conversion according to the type of each video data by described arm processor, and is sent to screen respectively through after decoding and coded treatment by the mode of divided frame, overlapping pictures or single picture.
The session that arm processor is corresponding according to each user's line is the data flow that each user's line sets up corresponding, and the agreement corresponding by this data flow carries out form decoding and coded treatment respectively to each video data.
The embodiment of the present invention also provides a kind of multichannel with the method for screen, as shown in Figure 2, comprise: A, receive and come from the dissimilar video data of video-unit, described dissimilar video data is identified, then described dissimilar video data is broken;
B, by partition after video data carry out format conversion according to the type of each video data, and respectively through decoding and coded treatment after be sent to screen by the mode of divided frame, overlapping pictures or single picture.
In the above-described embodiments, in described step B, more specifically, a session corresponding according to each user's line is the data flow that each user's line sets up corresponding, and the agreement corresponding by this data flow carries out form decoding and coded treatment respectively to each video data.
First the video-unit of user side carries out with shielding line by its same screen agreement (as Miracast, AirplayChromecast) supported and multichannel provided by the invention with screen device,
M1, M2, M3 in legend represent three tunnels independently Miracast line respectively, and C1 is chromecast line, and A1, A2 are then Airplay line, and these directly enter the WiFi receiver module of multichannel with screen device with screen line.
WiFi receiver module by the video data received according to identifying, according to the result identified, carry out with the partition of screen signal, to be split into dissimilar video data, different video datas is sent to arm processor and each line is complied with its type respectively by Miracast, Chromecast and Airplay carries out multichannel with shielding signal transacting with screen agreement, and the same screen agreement as corresponding according to respective video data respectively carries out decoding, encoding or repairing treatment.
In above-mentioned Application Example; Wifi receiver module is the line demand that the program of a daemon (background program) kenel is used for accepting user; process connection line operation foremost; after receiving user side line demand; set up independently session according to line type, different lines has different link process operations, for the line of Miracast; line can be set up based on WiFi Direct/WPS (WiFi-Protected Setup, Wi-Fi protection setting) agreement.Airplay is then based on Bonjour, ROAP (Remote AudioOutput Protocol, remote audio output protocol) set up line, Chromecast is then based on DIAL (DIscovery And Launch, the stream media protocol of YouTube and Netflix) set up line, so the operation of this part is after receiving the line demand of user side, can first carries out identification line type, then know the predetermined processing connection line operation of abiding by respective different agreement.
Each user's line has an independently session, so arm processor can maintain an independently data flow for each line, the host-host protocol of these same data flow is equally have the different practices according to different agreements, Chromecast is based on HTTP (Hyper Text Transfer Protocol, HTML (Hypertext Markup Language)), Airplay is then based on HTTP/RTSP (Real Time Streaming Protocol, a kind of real time streaming transport protocol)/RTP (Real Time Transport Protocol, the RTP developed by IETF), Miracast is then based on RTSP and RTP.
Dissimilar line, its data format is also different: Chromecast video be H.264 audio frequency be these forms of AAC, MP3, Ogg Vorbis, WAV; Airplay video is MPEG-4, H.264, M-JPEG audio frequency supports MP3, AAC form; Miracast's is MPEG2-TS form, so each line can have different audio-visual characteristics.
Then the output of multichannel with screen signal is carried out: during the process in the end exported, according to the operation of setting with user, the same screen signal of multichannel can be outputted to projector or LCD, TV with divided frame, overlapping pictures or single picture, wherein:
Single picture exports: although be have multichannel homogenous frequency signal line, and only select a road signal wherein to export, other are then maintain line but do not export picture, and user can switch the line picture selecting to export fast;
Divided frame export: be screen is done two segmentations or four segmentation separate by user arrange individual signal is rendered on different divided frame regions respectively;
Overlapping pictures exports then: be the content of line stacked on picture in the mode of form.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
