Description
Technical field
The utility model relates to Digital Video Processing technology, protection and monitor field, particularly relates to a kind of storage device based on the SDI HD video.
Background technology
SDI is Serial Digital Interface, i.e. digital non-compress technique.Video has two kinds to process the path: the non-compression of video compression or video through after the analog-to-digital conversion.The IP prison compresses processing to video exactly, and its benefit is a large amount of compression bandwidth of generation and is controlled between the 1-8M, makes video become possibility in the IP network transmission; But the limited storage space system of video data, in order to squeeze out more memory space, video data is compressed, but the image/video of preserving after the compression exists problems, fuzzy such as video, image quality is unclear, loss in detail can not be preserved the problems such as the high-definition image at crucial moment or static high definition photo.If video is that to carry out that digital non-compression processes be SDI, do not recompress after the video analog-to-digital conversion, just carry out code storage by particular form.
It is SD SDI that SDI is divided into 3 standard: lSD-SDIl according to video resolution and frame per second at present, mainly for SD resolution, video bandwidth after per second 25 frames or 30 frames (resolution is Phase Alternation Line system and TSC-system) number transforms is roughly about 250Mbps, HD-SDI is high definition SDI, this standard is 1080P mainly for resolution, frame per second is 25 or 30, data volume after the analog-to-digital conversion is 1.485Gbps:3G-SDI, high aloof from politics and material pursuits frame per second SDI, resolution still is 1080P, but frame per second increases to 50 or 60, and the data volume after the analog-to-digital conversion is 2.97Gbps.This shows that the original data volume without compression after the video analog-to-digital conversion is very large, if without compression, so large data volume is directly stored, and memory capacity will be very surprising.
The utility model content
The utility model is to overcome above-mentioned weak point, and purpose is to provide a kind of storage device based on the SDI HD video, effectively stores SDI HD video data in limited memory space.
The utility model is to achieve the above object by the following technical programs: a kind of storage device based on the SDI HD video comprises: video input module, video conversion module, video capture module, memory module, external alert trigger module, alarm module; Described video input module is connected with video conversion module, video capture module, and memory module is connected with video conversion module, video capture module, alarm module, and alarm module is connected with the external alert trigger module; Described video input module is also exported respectively high definition without time delay video, static high-definition image, SDI HD video fragment with video information transmission to video conversion module, video capture module, alarm module, is saved in the memory module.
Described memory module comprises: high definition is without time delay video memory block and high definition static images memory block; Described high definition comprises the normal storage district without the time delay video memory block and reports to the police and trigger the memory block.
Described video conversion module is video coding circuit, the SDI high-definition image is converted to H.264 video image or the MPEG video image of standard.
Described video capture module per second is captured and is no more than 30 frames, and the resolution of static high-definition image is 1920 x 1080 or 1280 x, 720 pixels.
The beneficial effects of the utility model are: 1) can preserve high-definition image or the static high definition photo at crucial moment, satisfy the storage demand of SDI high clear video image; 2) preserved report to the police before and after the HD-SDI high definition realtime graphics of a few minutes, provide strong evidence to the analysis on accident cause in later stage; 3) video complete display provides intelligent monitoring required best high-definition image source effectively.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment the utility model is described further, but protection range of the present utility model is not limited in this:
Embodiment 1: as shown in Figure 1, a kind of storage device based on the SDI HD video comprises: video input module, video conversion module, video capture module, memory module, external alert trigger module, alarm module.Described video input module is connected with video conversion module, video capture module, alarm module, and described video conversion module, video capture module, alarm module are connected with memory module, and described external alert trigger module is connected with alarm module.
The function and efficacy of each module:
1. video input module: the SDI video information that the receiving front-end video camera transmits is also exported the SDI video information.
2. video conversion module: the SDI video information is carried out video format conversion by video coding circuit, the SDI high-definition image is converted to H.264 video image or the MPEG video image of standard.
3. video capture module: the SDI video information is captured static high-definition image from the video capture circuit, arranges and captures static high-definition image with per second 1-30 frame, and the resolution of static high-definition image is 1920 x 1080 or 1280 x, 720 pixels.
4. alarm module: reporting to the police to trigger has two kinds: a kind of is by the external alert module; Two kinds is the video identification mode in addition.
5. external alert module: the form with serial ports, network interface gives the alarm module triggering signal.
6. memory module: be divided into high definition without time delay video memory block and high definition static images memory block, high definition is the normal storage district without the time delay video memory partitioning and reports to the police and trigger the memory block.Wherein the normal storage district is used for H.264 video image or the MPEG video image that the store video modular converter sends; High definition static images memory block is used for memory image and captures the static high-definition image that module sends; Report to the police and trigger the SDI video segment that the memory block is used for the transmission of store alarms module.
Above described be specific embodiment of the utility model and the know-why used; if comply with the change that conception of the present utility model is done; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, must belong to protection range of the present utility model.
