Problems solved by technology

However, if you use the computer to access the hard disk to read and play the video, firstly, the capacity of the hard disk will be very difficult for the several terabytes of data collected by the front-end HD camera, and secondly, the speed of the computer to access the hard disk (assuming 100MB/S) is far away. It is less than the

[0035] The present invention will be further described below in conjunction with the drawings:

[0036] Such as figure 1 As shown, the uncompressed video playback system is divided into the following modules:

[0037] Input and output multiplexing interface module 1, FPGA main control processing module 2, ARM control module 3, storage unit 4, function expansion interface module 6, and power supply module 5.

[0038] Input and output multiplexing interface module 1: All use TTL / CMOS level standard standard video interface bus, this bus includes 24-bit data line + 4 bit control signal + 1 bit clock signal, the bus is connected with the main control processor FPGA, And input and output interfaces can be used as function multiplexing interfaces.

[0039] Function reuse description:

[0040] For the input interface module, (a) can be used as the data input interface of the image / video acquisition equipment. Since we use a standard video bus interface, for any front-end acquisition equipment...

Abstract

The invention discloses an uncompressed video play system and method. An input/output multiplexing interface module of the system is connected with an FPGA (Field Programmable Gate Array) of a main-control processing module to serve as a data input/output interface of image/video acquisition equipment; the FPGA main-control processing module serves as a main-control processor to achieve shunting cache of data input by the front-end image/video acquisition equipment, and the data is stored in a memory unit; an ARM control module is connected with the FPGA main-control processing module and used for building file system mapping for recorded high-volume data and providing an operating system; the memory unit is formed by arrangement of a plurality of NAND FLASH arrays; the system achieves uncompressed storage record of image/video data, and provides an extensible video play interface to support uncompressed play display of images/videos; the input/output interface adopts a standard video interface, and a converter plate is used together, so that the uncompressed video play system can adapt to any input/output equipment interfaces, and accordingly, the flexibility is high.

Description

technical field [0001] The invention belongs to the field of real-time recording and uncompressed playback of high-speed and large-capacity image / video data, and relates to a non-compressed playback system and a playback method. Background technique [0002] With the continuous advancement of science and technology, photosensitive devices such as CCD and CMOS have also achieved rapid development. In the 1990s, CCD was able to achieve a high resolution of one million pixels. Driven by the principle of pursuing a more authentic restoration of nature and recording the world, the development of photosensitive devices will inevitably not stop, and now even so-called ultra-high-resolution CCD devices have appeared. However, despite the near-perfect recording of our natural world using these sensor technologies, no device has yet been able to reproduce captured images / videos of this size intact. The current image / video capture card is to store the collected data in a computer afte...
