Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The structural representation of the audio/video information transmission system that Figure 1A provides for one embodiment of the invention.As shown in Figure 1A, the audio/video information transmission system of the present embodiment comprises: projecting apparatus 11, projection screen 12, notebook 13 and WirelessHD technology (Wireless Display, referred to as WiDi) receiver 14.Wherein, WiDi receiver 14 in use, can be plugged on the audio-video interface of projecting apparatus 11, and inserting mode is as shown in the arrow line in Fig. 1.
The present embodiment be take WiDi receiver 14 and is described as example as wireless receiver, but is not limited to this.Based on this, the audio-video interface on projecting apparatus 11 can be HDMI (High Definition Multimedia Interface) (High Definition Multimedia Interface, referred to as HDMI).The mobile terminal high-definition audio and video standard interface of WiDi receiver 14 (Mobile High-Definition Link, referred to as MHL) is plugged in the HDMI of projecting apparatus 11.Between notebook 13 and WiDi receiver 14, with wireless mode, communicate, the communication adopting can be bluetooth, Wireless Fidelity (Wireless Fidelity, referred to as WiFi) etc., the present embodiment be take WiFi as example, is WiFi network as shown in Figure 1 between notebook 13 and WiDi receiver 14.
Wherein, WiDi is the technology of computer and display device wireless connections that realizes by WiFi signal, and WiDi receiver 14 is receivers that a kind of WiDi of employing technology realizes, and has volume little, and disposal ability by force, is especially supported the advantages such as output of high definition picture.What WiDi receiver 14 adopted is MHL interface, this MHL interface is a kind of audio-visual standard interface that connects portable consumer electronic device, can compatible universal universal serial bus (Universal Serial BUS, referred to as USB) interface, therefore support USB function, and can support 720p/60 or 1080i/60(to be equivalent to 1080p/30) such display format, the 720P is here a kind of at the display format of the resolution that is issued to 1280 * 720 of lining by line scan, direct and standard HDMI directly pegs graft, flexibility and convenience when WiDi receiver 14 uses have been improved.In addition, this MHL interface can also for example have receiving terminal to provide for example power supply of 5V to WiDi receiver 14 as charging inlet, for charging.That is to say, MHL interface is supported the function of HDMI interface, USB interface and charging inlet simultaneously, has realized three mouthfuls of unifications, has effectively reduced the number of interface on WiDi receiver 14, is conducive to the miniaturization of WiDi receiver 14.
At wireless receiver, be on the basis of WiDi receiver 14, system shown in Figure 1 middle pitch video information transmission process as shown in Figure 1B, comprising:
The audio/video information transmission system of the present embodiment is usingd notebook 13 as transmitting terminal the signal source of audio/video information (as), but is not limited to this, such as being mobile phone, panel computer or game machine etc.The mode that different transmitting terminals is obtained audio/video information is different.For example, if transmitting terminal is notebook computer or panel computer etc., its mode of obtaining audio/video information can be to download from the Internet, or receive the audio/video information that other equipment (such as audio/video server etc.) send, or directly from local memory space, obtain audio/video information.If transmitting terminal is mobile phone, its mode of obtaining audio/video information can be from the Internet, to download (this mobile phone is supported function of surfing the Net), or receive the audio/video information that other user mobile phones transmit in short haul connection modes such as bluetooth, WiFi, or receive the multimedia message that other users send, from multimedia message, obtain audio/video information etc.
Said process is specially: in advance WiDi receiver 14 is inserted on the HDMI interface of projecting apparatus 11.Notebook 13 is opened its WiDi function, by automatically find WiDi receiver 14 in WiFi network, then sets up WiFi with WiDi receiver 14 and is connected, and connected to WiDi receiver 14 and sent audio/video information by the WiFi setting up.WiDi receiver 14 is connected and is received the audio/video information that notebook 13 sends by WiFi, optionally, WiDi receiver 14 can buffer memory audio/video information and it is decoded and processes and then export to projecting apparatus 11 by the HDMI interface of projecting apparatus 11, projecting apparatus 11 is play and/or storage audio/video information, for example projecting apparatus 11 spreads out of audio/video information to projection screen 12 and shows, thereby has realized the image transmission on the screen of notebook 13 to large-screen and then obtained the object of better visual effect.Wherein, notebook 13 and WiDi receiver 14 are set up the mode that WiFi is connected and can be: the linkage function (such as a button or connectivity option etc.) that user clicks notebook 13 to be provided is set up WiFi with WiDi receiver 14 and is connected.
