Description
Technical field
The present invention relates to image capture device, the Radio Transmission Technology of image accepting device and image.
Background technology
The very fast development of Wearable camera-shooting and recording device in recent years, its wearing mode is also varied, and comprise wear-type, waist wears formula, and the mode such as weared on wrist, Wearable camera-shooting and recording device includes Google's glasses, Hewlett-Packard's glasses and a lot of military project aspects Wearable camera-shooting and recording device.But this Wearable camera-shooting and recording device all must solve an image or picture transfer problem, because be Wearable, in a lot of situation, not can solve the problem of watching at any time, relaying at any time, storing at any time, print at any time of image or picture.Present Wearable solution this viewing at any time, at any time relay, the scheme stored at any time have three kinds, one is by being wiredly connected to above the display memory device such as computer, mobile phone or printing device above Wearable camera-shooting and recording device, the second is connected with the display memory device such as computer, mobile phone or printing device by bluetooth, also can address this is that.The third scheme be by wifi local area network (LAN) be connected to computer, mobile phone etc. display memory device or printing device solve.But above three kinds of schemes all can not solve the Lossless transport wearing convenience, image or picture, do not compress transmission, and the real-time Transmission of image simultaneously.
Although the first wired scheme can solve the Lossless transport of image or picture, do not compress the real-time Transmission of transmission and image or picture, but on the convenience worn, there is very large problem, when shooting with video-corder, the movement of human body with the movement of moving-wire, can bring a lot of inconvenience to shooting with video-corder.
The second Bluetooth transmission scheme also has a lot of application in Wearable camera-shooting and recording device, but be in most cases be connected with mobile phone, the effect transmitted is also bad, and general transmission can only transmit the file having recorded and stored, and can not realize the real-time Transmission of image or picture.
The third Wifi transmission plan is not that requirement is very high in the clear specification of image or graphic image, and wifi signal around can realize real-time image or picture transfer when not being very numerous and diverse, but in the middle of normal environment, because be covered with a lot of frequency signal in space, very strong interference is had to wifi transmission, the speed causing wifi to transmit is very low, the image of the real-time Transmission that can realize or the non-constant of the clear specification of picture, very high standard can not be reached and (comprise 2K, image transmission 4K), and in the process of transmission, must first through Image Data Compression, the amount transmitting data is diminished, then wifi transmission is carried out, after receiving terminal receives image frame, if need to play, first must carry out the work decompressed, data decompression is shortened into display device acceptable data format, just can show.But this process is because carried out the compression of data, transmission, decompress, display, because compression and decompression cause view data to be lost, image quality becomes non-constant, and the interference of environment, cause transmission rate also not all right, add compression and decompression, overall real-time broadcasting there will be the phenomenon of blocking very much and timing, and can not realize the effect that real-time recording is play in real time completely.Overall process data is through too many process, for wearable device, very power consumption, and transmission equipment generally has very high requirement to size and weight, power consumption too conference causes the flying power of electricity to be deteriorated, and the flying power of such Wearable camera-shooting and recording device can only adhere to several hours.Above these can as a setting with solve technical problem.
Summary of the invention
On the image data wireless transmission scheme of Wearable camera-shooting and recording device, select the transmission plan of WHDI, this transmission plan can solve the Lossless transport wearing convenience, image simultaneously, does not compress transmission, and the problem of the real-time Transmission of image.
Wearable camera-shooting and recording device, connected with WHDI transmitting terminal by HDMI, the image of shooting with video-corder or picture are transferred to the data transmitting terminal of WHDI by HDMI, directly through launching, the receiving terminal of WHDI can directly receive, the receiving terminal of WHDI can by conventional interface directly with computer, the display memory device such as mobile phone or printing device connect, and the frequency range that his transmission uses follows frequency range common in surrounding environment not within a scope, so the bandwidth of transmission reaches 3Gb/s, the transmission width of passback reaches 100KB/s, transmission image and image all without any Caton phenomenon.Forward transmission can realize the nothing compression of 2K HD video, undelayed transmission.Reverse data width can realize the control signal of some complexity, the transmission of voice signal etc.
WHDI data receiver is connected with data collecting card by HDMI, and capture card is connected with memory device mainboard by distinctive interface, the data of the uncompressed that WHDI receiving terminal can be received are carried out Real-time Collection compression and are then stored in memory device, as PC etc.
Follow display device (as projecting apparatus by common interfaces the receiving terminal of WHDI, display screen) be directly connected together, image Wearable camera-shooting and recording device can shot with video-corder and picture without compression, without time delay, lossless image specification be presented at above display device in real time.
WHDI data receiver is connected with data collecting card by HDMI, data can be carried out Real-time Collection so and be connected with PC by capture card, connected by the network interface calcaneus rete network of PC main frame, can in real time by the image that collects or picture transfer to live scene, by live scene playback equipment play, thus realize the effect of Wearable camera-shooting and recording device remote living broadcast.
WHDI data receiver is connected with data collecting card by HDMI, the Wearable image of shooting with video-corder and speech data can carry out Real-time Collection so and be connected with PC by capture card, connected by the network interface calcaneus rete network of PC main frame, can in real time by the image that collects or picture transfer to live scene, the voice marking that the sound equipment of adopting at live scene collects returns to WHDI through network, then pass to Wearable camera-shooting and recording device, thus realize interactive voice.Remote medical consultation with specialists can be applied in, the aspects such as remote teaching.
The transmission width of WHDI passback reaches 100KB/s, WHDI data receiver is connected with data collecting card by HDMI, data can be carried out Real-time Collection so and be connected with PC by capture card, can by some simple states of instruction control camera-shooting and recording device on PC.
Data handling procedure tails off, and solves power consumption problem, well extends the flying power of battery, can solve the problem of traditional Wearable camera-shooting and recording device flying power difference.Except the object of description described above, feature and advantage, the present invention also has other objects, feature and advantage.Below with reference to accompanying drawings, optimum execution mode of the present invention is described.
