Abstract

The invention discloses a high-definition video live broadcast system. The system includes: a video acquisition module, an HEVC compression encoding module, an RTP protocol encapsulation push module, a multi-network transmission module, a user interaction module and a system management module; the video acquisition module It is used to collect the high-definition video original image stream, and send the collected high-definition video original image to the HEVC compression coding module or directly output to the LCD display after preprocessing; the HEVC compression coding module compresses the high-definition video image stream and sends it to The RTP protocol encapsulation push stream module; the RTP protocol encapsulation push stream module packages and encapsulates the video naked stream and outputs it to the multi-network transmission module; the multi-network transmission module fragments and packs the RTP packet data according to the destination address and port sent to the destination host. The invention is based on the design of the HI3519 chip, which improves the compatibility of the system to the resolution of the input source, and at the same time, the multi-network transmission module based on the open source video design improves the network adaptability of the system.

Description

technical field [0001] The present invention relates to the field of video live broadcast, and more specifically, to a high-definition video live broadcast system. Background technique [0002] With the rapid development of the Internet age, the way for people to obtain information tends to be more instant, especially the demand for live broadcast is increasingly strong. Traditional broadcast-level live broadcast equipment has a complex structure, difficult equipment construction, and high professional requirements for users. However, due to the low definition and lack of stability of traditional mobile phone live broadcast, it cannot be connected to high-definition photography equipment and other defects, which makes it incapable of performing scenes that require high definition and high stability of live broadcast. Therefore, a high-definition video live broadcast system that is easy to carry, easy to use for non-professional users, and adaptable to various scenarios need...
