Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
The structural representation of a kind of video encoder that Fig. 1 provides for the utility model embodiment.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Be illustrated in figure 1 as the embodiment of a kind of video encoder described in the utility model, comprise the front end camera lens 1 that is used for the images acquired signal; Imageing sensor 2, the input of this imageing sensor 2 is electrically connected with described front end camera lens 1, is used to amplify the picture signal that described front end camera lens 1 collects; Digital to analog converter 3, the input of this digital to analog converter 3 is connected with described imageing sensor 2 outputs, is used for converting the image analoging signal of described imageing sensor 2 outputs to digital signal; Singlechip chip 31 is electrically connected with described digital to analog converter 3, and described singlechip chip 31 is used for the digital signal of described digital to analog converter 3 outputs is reduced into analog signal; The interface unit 4 that is used for transmission signals, its input is electrically connected with described digital to analog converter 3, and the output of described interface unit 4 is connected with high definition encoding board 5; Described high definition encoding board 5, its input is connected with interface unit 4, is used for analog signal conversion is become the digital signal of high definition.
Usually the TV that vertical display resolution is reached more than 720 lines is called HDTV (High-Definition Television) in the world.In the formal national high definition standard of implementing on January 1st, 2007, its physical resolution of display device reaches the 720P standard to the standard of high definition, promptly more than the 1280*720 according to China in the present embodiment.
ISP is current popular mcu programming pattern, at system programmable, refers to that blank components and parts on the circuit board can be programmed to write end user's code, and does not need to take off components and parts from circuit board.The device of having programmed also can be wiped or programming again with the ISP mode.The singlechip chip of the utility model embodiment adopts the ISP chip, the performance height, reliable and stable, power is extremely low, high compression ratio, high image quality, and color rendition is true, has abundant procotol.
Video encoder also comprises output unit 6, is connected with the output of described high definition encoding board 5, is used for exporting the high-definition digital signal of described high definition encoding board 5 outputs to outside management equipment.
After the electric image signal that front end camera lens 1 collects is amplified by imageing sensor 2, ISP chip 31 utilizes digital to analog converter 3 that the signal of telecommunication is reduced into analog signal, analog signal inserts high definition encoding board 5 by interface unit 4, high definition encoding board 5 utilizes H.264 compress mode, each frame of video is separated into the piece of forming by pixel, adopt the method for spatial redundancy, some original blocks to frame of video carry out spatial prediction, conversion, optimize and entropy coding, different masses employing to successive frame is deposited temporarily, adopt the remaining space redundant technique, the residual block in the frame of video is encoded.
