Abstract
The utility model discloses a computer interface circuit of extremely clear video camera of optic fibre, its by the optical fiber interface, decode and framing module, PCIe interface module are constituteed. The signal of the extremely clear video camera of optic fibre is carried via the optical fiber interface and is decoded and the framing module, constitutes the picture frame according to the UHDTV standard, through the PCIe bus connection of PCIe interface with the computer.
Description
Technical field
This patent relates to a kind of digital camera.
Background technology
The generally signal of video camera is input in computer by video frequency collection card.Resolution along with video camera
More and more higher, when common cable is difficult to bear semaphore huge pressure, signal-bearing media can use optical fiber.
Therefore, camera extremely clear for optical fiber, its scheme being connected with computer is usually used video optical multiplexer
Plus the capture card of applicable UHDTV, but this scheme can bring high cost price.
Utility model patent content
It is defeated that the purpose of this patent is to use the mode of simple and direct low cost to solve the extremely clear camera output signal of optical fiber
Enter the problem to computer.
Realize the technical scheme of above-mentioned purpose:
The Computer interface circuit of the extremely clear camera of a kind of optical fiber, including fiber interface module, decoding and framing
Module, PCIe interface module, as shown in Figure 1.Described fiber interface module is used for connecting optical fiber, from optical fiber
Receive the signal from the extremely clear camera of optical fiber, and fiber-optic signal is converted into the signal of telecommunication；Described decoding and group
Frame module is for going out the signal resolution that extremely clear for the optical fiber having been received by and being converted into signal of telecommunication camera conveying comes
Clock signal, frame start signal, start of line signal and valid data, and according to UHDTV standard according to above-mentioned
The beat of the clock signal parsed by above-mentioned valid data according to the instruction of the start of line signal parsed with
RGB mode is arranged in order and is equipped with clear data and forms a data row, parsed according to above-mentioned by each data row
The instruction of frame start signal and be equipped with blank line and form a picture frame, and by the aforementioned clock signal parsed
Frequency this picture frame is transported to PCIe interface module；Described PCIe interface module is used for and computer
PCIe bus connects, and is responsible for the picture frame decoded and the conveying of framing module comes is input to computer.
Using technique scheme, what this patent was useful has the technical effect that directly by extremely clear for optical fiber camera
Signal be input to computer, and be no longer necessary to use expensive fiber data to transmit reception equipment and costliness
The capture card being suitable for UHDTV.
Accompanying drawing explanation
Fig. 1 is the Computer interface circuit block diagram of the extremely clear camera of a kind of optical fiber.
Fig. 2 is the embodiment of the Computer interface circuit of the extremely clear camera of a kind of optical fiber.
Detailed description of the invention
The Computer interface circuit of the extremely clear camera of a kind of optical fiber, including optical fiber interface 1, decoder module 2, group
Frame module 3 and PCIe interface 4, as shown in Figure 2.Optical fiber interface 1 is photographed the most clearly from optical fiber for receiving
The signal of machine output, and the optical signal of input is converted into the signal of telecommunication is transported to decoder module 2；Decoder module 2
For the signal resolution from optical fiber interface 1 is gone out clock CLOCK, frame start signal Vsync, the start of line
Signal Hsync and data DATA, and these data and signal are transported to framing module 3；Framing module 3
For data DATA being pressed the beat of CLOCK with RGB according to the instruction of Hsync according to UHDTV standard
Mode is arranged in order and is equipped with clear data and forms a data row, depended on according to the instruction of Vsync by each data row
Secondary arrangement is also equipped with blank line and forms a picture frame, and this picture frame is transported to PCIe interface 4；PCIe connects
Mouth 4 is for being sent to this image frame data in this computer PCI e bus connected.For meeting extremely clear image
Data bandwidth, PCIe interface 4 uses 16-lane PCIe.
