Small-sized video encoding equipment, and video capture, coding and transmission system

Abstract

The invention discloses small-sized video coding equipment, and a video capture, coding and transmission system. The small-sized video coding equipment is provided with a video processing module, a USB (Universal Serial Bus) interface, a voice frequency transmission circuit, a video transmission circuit and an AV (Audio Video)interface, wherein the AV interface is used for being connected to a camera, receiving voice frequency signals and video signals collected and output by the camera, and sending the voice frequency signals and the video signals to the video processing module through the voice frequency transmission circuit and the video transmission circuit; after being encoded by the video processing module, the voice frequency signals and the video signals are transmitted to the USB interface. The video encoding equipment provided by the invention is small in size, low in power consumption and high in compression ratio, and can be used with a PC (Personal Computer) or terminal devices with network functions in a matching manner; after being encoded, a shot video picture is sent to a remote server by a wired or wireless network so as to realize real-time capture and remote monitoring of an on-site picture. Meanwhile, by using a USB interface power supply mode, the coding equipment does not need to be equipped with an independent power supply, is easy to carry and install, and can be conveniently used together with existing equipment.

Description

technical field [0001] The invention belongs to the technical field of video encoding and decoding equipment, and in particular relates to a miniaturized video encoding equipment and a set of video acquisition, encoding and transmission systems designed using the miniaturized video encoding equipment. Background technique [0002] With the continuous development of information technology and digital technology, video capture technology has been widely used in more and more fields. At present, there are not a few devices based on H.264 codec at home and abroad, which are mainly divided into the following three categories: [0003] The first type is a box-type device with a relatively large volume and power consumption. This type of device generally uses an external AC mains power supply for the device, and uses an Ethernet interface to transmit encoded and decoded data to the server through the Ethernet network; [0004] The second category is small portable devices. This ty...

Problems solved by technology

[0004] The second category is small portable devices. This type of device mostly adopts the integrated method of video encoding and front-end video acquisition for system design. Although it is convenient to use, it lacks scalability and flexibility and cannot be used with existing devices;

Although this kind of modular equipment is small in size and easy to carry; however, there are also many problems such as lack of flexibility and scalability, the need to configure an independent power supply, and the inability to choose front-end cameras at will.
