Abstract

The invention provides an encoding system. The system comprises an SOC chip. H.265 audio and video code streams pass through an SATA2.0 (Serial Advanced Technology Attachment 2.0); are written and stored into an HDD hard disk. Meanwhile, the H.265 audio and video code stream is also transmitted to the outside of the controller through the USB3.0 channel. An SOC chip is subjected to various parameter configurations and system control by the CPU. The DRAM is in communication with an external upper computer (a smart phone or a portable computer) through USB3 and 0 channels, an image cache is connected to the DRAM through a DDR controller, a program of a CPU is stored in a FLASH chip, and the program is read to be executed in the DRAM when the CPU is started. The encoder circuit is reasonablein design and convenient and safe to use.

Description

technical field [0001] The invention belongs to the field of high-definition video live broadcast, and in particular relates to a 4K-H265 encoder based on a high-definition audio and video live broadcast system. Background technique [0002] With the advent of the self-media era, webcast technology is developing rapidly, and its functions are changing with each passing day. Due to the problems of clarity, resolution, sound quality and picture quality, the traditional mobile phone selfie live broadcast gradually fails to meet the needs of mid-to-high-end live broadcast applications. However, traditional broadcast-level live broadcast equipment cannot meet various requirements, especially due to the complexity of equipment and heavy weight. Demand for outdoor live streaming. Based on the above problems, it is very important to develop a portable 4K high-definition audio and video live broadcast system, and the development of a 4K-H265 encoder that can meet the high-definition...
