Abstract
In the method, a one hand, transmitting compression technique is used to adjust image transmission speed dynamically to make it match with existing band width of network as well as coding technique is used to ensure quality of image transmission simultaneously, on the other hand, transmission coding technique is applied to make it possible to carry on synchronous interactive transmission with multiple mode of multiflow image, in image transmission procedure. The device is structured by connecting emission unit with front end of information transmitting channel and connecting several hand control equipment with the information transmitting channel in parallel.
Description
Technical field
The present invention relates to a kind of video signal transmission and method and the device thereof handled.Belong to image transmission and treatment technology and isolated plant thereof in the IP network multimedia application.
Background technology
Because IP network is used widely as the communication platform of an opening and is popularized, following Digital Television, computer, phone and the household electrical appliance etc. all will become the application interface of IP network, so IP-based image applications technology will become following mainstream technology of leader.
At present, existing image transmission means, single to utilizing of broadband, utilance is low, in fact can not satisfy different receiving equipments different systems and different images are received excessive requirement.
Summary of the invention
The object of the present invention is to provide a kind of image to transmit and method and the device thereof handled,, under the condition that does not change original video-signal system equipment, realize, efficiently transmission and processing more convenient video signal in order to overcome the deficiency of above-mentioned prior art; Extensively realize the IP network multimedia application simultaneously, high-quality, low cost, the reliable image transmission platform of multi-user are provided.
Image transmission of the present invention with the method for handling is: in the image transmission course, adopted the transmission compress technique dynamically to adjust the transmission speed of image, the existing bandwidth of itself and network is complementary, dynamically uses coding techniques simultaneously to ensure the image transmission quality; And adopted the transfer encoding technology to make the multithread image of multiple standard can carry out the synchronous interaction transmission.
The multi-path digital signal flow of input carries out dynamic coding in first module, convert high code check to low code check, is input in the mpeg processor then and compresses; After packing data, export to the multi-channel video user by the speed of per second 30 frames; Stored the program of relevant controlling image transmission rate and compression in the synchronous dynamic storage control, it is controlled mpeg processor according to the existing network bandwidth, in 100Kbps transmission rate of conditioning signal stream dynamically in the 2Mbps bandwidth.
In the device of image of the present invention transmission and processing: emitter is connected with the front end of information transfer channel, and several palm control appliances are parallel on this information transfer channel; Device adopts 32 pci bus interface.
The present invention has following characteristics: (1), support provide bit rate and form conversion (Bit-Rate, Format Transcoding) simultaneously for a plurality of video channels, and Code And Decode reaches the video regulatory function that multiple suitable wideband is broadcasted.(2), digital video channel and Internet can two-in-onely be presented on the same video equipment.(3), cable tv broadcast can exempt wired constraint, makes the user enjoy wireless mobile enjoyment and convenient.(4) but, all Live Audios of all devices wireless connections and Online activities, function is included as the mobile subscriber and is provided at hand-held device (PDA) and watches news, physical culture, weather and finance and economics message immediately, the services such as (Voice Over IP-VOIP) of the every e-mail and the networking telephone; For utilizing TV, the domestic consumer surfs the web; Be the brand-new channel promotion of advertiser's creation at different consumers.(5), the present invention adopted the transmission compress technique dynamically to adjust the transmission speed of image, and its existing bandwidth with network is complementary, and dynamically uses coding techniques with guarantee image transmission quality simultaneously; On the other hand, the present invention has adopted the transfer encoding technology to make the multithread image of multi-modulation scheme can carry out the synchronous interaction transmission.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
In the image transmission course, adopted the transmission compress technique dynamically to adjust the transmission speed of image, its existing bandwidth with network is complementary, dynamically use coding techniques with guarantee image transmission quality simultaneously; And adopted the transfer encoding technology to make the multithread image of multiple standard can carry out the synchronous interaction transmission.
In the device of image of the present invention transmission and processing: emitter is connected with the front end of information transfer channel, and several palm control appliances are parallel on this information transfer channel.Aforesaid connection can be a wired connection, also can be wireless connections.
This image transmission comprises information launching centre, IP network, each palm control appliance such as TV, computer, phone and other household electrical appliance with treatment system.After information is sent by the information launching centre, arrive each palm control appliance through Network Transmission, as TV, computer, phone and other domestic electric appliance; During this time, this device carries out Code And Decode by the conversion of bit rate and form is provided simultaneously for a plurality of video channels to all information, the information of sending by information centre is become by adjusting be fit to the video that wideband is broadcasted.For example, a kind of network that special connection hand-held device is provided for public situation such as shopping center, hotel and Stadiums.The backbone of this network can be made up of the digital broadcasting of wideband (wired or satellite), the Internet and the gateway that is equipped with the WLAN (wireless local area network) tie point, and all hand-held devices of being furnished with the wireless LAN card annex can utilize LAN software and gateway to connect.Adopting native system is to provide at present to reduce the accessory cost and improve the best solution that multi-medium video-signal passes yield.
The multi-path digital signal flow of input carries out dynamic coding in first module 1, convert high code check to low code check, is input to then in the mpeg processor 3 and compresses.After packing data, export to the multi-channel video user by the speed of per second 30 frames, this fixing speed has guaranteed picture quality.
Stored the program of relevant controlling image transmission rate and compression in the synchronous dynamic storage control 2.It is controlled mpeg processor according to the existing network bandwidth, in 100Kbps transmission rate of conditioning signal stream dynamically in the 2Mbps bandwidth.
This device can adopt 32 pci bus interface 5.Encryption and decryption technology 4 is provided simultaneously, has supported DES, 3DES, AES and DVB-CSA form, guaranteed the image safety of transmission effectively.
Claims (3)
1, a kind of image transmission and the method for handling, it is characterized in that: in the image transmission course, adopted the transmission compress technique dynamically to adjust the transmission speed of image, its existing bandwidth with network is complementary, dynamically used coding techniques simultaneously with guarantee image transmission quality; And adopted the transfer encoding technology to make the multithread image of multiple standard can carry out the synchronous interaction transmission.
