Abstract
A wireless high-definition projector comprises an HDMI transmission reception module, a signal processing unit, and a projector engine, which are arranged inside the projector. The HDMI transmission reception module comprises a WHDI receiver and an HDMI receiving board. The HDMI transmission reception module is connected with the signal processing unit. The signal processing unit is respectively connected with an YpbPr/RGB/Video receiving board, an audio decoder, and an LCD/DLP driving board. The LCD/DLP driving board is connected with the projector engine. As a wireless projector, the wireless high-definition projector of the utility model is advantaged by being good in image quality, good in tone quality, stable in transmission, and the like in terms of audio and video wireless transmission. The wireless high-definition projector adopts a global leading WHDI technology, and the wireless high-definition projector uses a 40 MHz channel within a frequency range of 4.9-5.9 GHz and has a transmission rate as high as 3 Gbps, so that the real-time wireless transmission of a lossless uncompressed 1080 P @ 60 Hz true cinema can be realized and a time delay-free wireless transmission novel conception can be genuinely achieved. The wireless high-definition projector has a plug-and-play function and requires no installation of software. The effective transmission distance of the wireless high-definition projector is 20 meters, thereby enabling audio and video playing to be no longer restricted by complex and messy cables.
Description
Technical field
The utility model relates to a kind of projection display system, especially relates to a kind of WirelessHD projecting apparatus.
Background technology
Wireless projector is based on the product that shadow casting technique and WirelessHD video technique combine, it is primarily aimed at existing conventional projector in use, need come the transmission tone vision signal by wired, shadow casting technique adopts traditional LCD or DLP shadow casting technique, by the mode of built-in wireless transport module, realize wireless transmission of signal.At present in the wireless video transmission technology for the transmission of video one to one and can only external (wiring is many, the space is big) significant limitation be arranged in use, what common wireless audio and video transmission product scheme adopted mostly is the 802.11G/N standard, Chang Yong WIFI wireless standard just, be subjected to the bandwidth restriction and can only realize the compression transmission, image quality and tonequality all can descend, also can join each other and give birth to disturb adopt the product display resolution of WIFI Radio Transmission Technology can only reach 720P at most but not the HDMI high definition, and transmission of audio signal simultaneously; Common WIFI wireless product is in the situation of carrying out can occurring when the audio frequency and video compression is handled unstable properties or transmission delay.
Summary of the invention
The utility model purpose provides a kind of WirelessHD projecting apparatus.To solve technical problems such as existing in prior technology projecting apparatus wireless audio and video wireless transmission image quality, lower tone, transmission instability.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of WirelessHD projecting apparatus comprises the HDMI transmission receiver module, signal processing unit, the projector engine that are arranged on projecting apparatus inside; Described HDMI transmission receiver module comprises WHDI receiver and HDMI dash receiver, and this HDMI transmission receiver module is connected with signal processing unit; Described signal processing unit is connected with YpbPr/RGB/Video dash receiver, audio decoder, LCD/DLP drive plate respectively; Described LCD/DLP drive plate is connected with projector engine.
As preferably, described WHDI receiver is connected with the WHDI sender wireless, and this WHDI transmitter is connected on the PC by USB.
As preferably, described PC is many, and all is provided with on every PC by USB and connects the WHDI transmitter.
As preferably, described signal processing unit is connected with remote controller.
As preferably, described WHDI receiver is connected with multichannel WHDI transmitter, and multichannel WHDI transmitter is optionally connected goes into a WHDI receiver, and by remote controller easy switching selector channel.
As preferably, the effective propagation path between described WHDI receiver and the WHDI transmitter is in 20m.
The utlity model has advantages such as wireless display instrument audio-video wireless transmits image quality, tonequality is good, transmission is stable.The utility model has adopted world-leading WHDI technology, in the 4.9-5.9GHz frequency range, use the 40MHz passage, transmission rate is up to 3Gbps, can realize the harmless real-time radio transmission of not having compression 1080P60Hz original film (True Cinema), really reach the wireless transmission new ideas of not having time-delay (less than 1 millisecond); Realize optionally connected people's one receiver of multichannel reflector, by remote controller easy switching selector channel, plug and play need not to install software; 20 meters effective propagation path allows audio-visually be not entangled in loaded down with trivial details and in disorder cable.
Description of drawings
Fig. 1 is operation principle block diagram of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Fig. 1 is operation principle block diagram of the present utility model.As shown in Figure 1, a kind of WirelessHD projecting apparatus mainly is made up of the HDMI transmission receiver module that is arranged on projecting apparatus inside, signal processing unit, projector engine etc.; Described HDMI transmission receiver module comprises WHDI receiver and HDMI dash receiver, and this HDMI transmission receiver module is connected with signal processing unit; Described signal processing unit is connected with YpbPr/RGB/Video dash receiver, audio decoder, LCD/DLP drive plate respectively; Described LCD/DLP drive plate is connected with projector engine.Described signal processing unit also is connected with remote controller.
The WHDI receiver is connected with the WHDI sender wireless, and this WHDI transmitter is connected on the PC by USB, and the effective propagation path between WHDI receiver and the WHDI transmitter is in 20m; Described PC is many, and all is provided with the transmitter by USB connection WHDI on every PC.The WHDI receiver is connected with multichannel WHDI transmitter, and multichannel WHDI transmitter is optionally connected goes into a WHDI receiver, and by remote controller easy switching selector channel, plug and play need not to install software.20 meters effective propagation path allows audio-visually be not entangled in loaded down with trivial details and in disorder cable.Select one the tunnel to transmit signalling channel by remote controller, the WHDI receiver receives the audio-video signal of WHDI transmitter, and this signal is transferred to the HDMI dash receiver, the HDMI dash receiver is transferred to signal processing unit by YUV24 and handles, export to the LCD/DLP drive plate by the audio-video signal after handling by DVI, the generation audio-video signal shows, sends projector engine to, on Projection Display screen externally.
