Problems solved by technology

For file compression transmission, the transmitted audio / video content cannot be viewed during the transmission process, and can only be viewed and processed after all receiving and saving is completed; streaming media transmission is viewed while receiving, and the receiving end can only watch, not at the receiving end at the same time It is stored and processed, which is not conducive to use in broadcasting, military, etc.

Abstract

The disclosed network transmission method for audio / video data comprises: with real-time frame-to-code technology, coding the being-transmitted high code rate data with audio / video frame as unit, compressing and packing to send to the receive end; on the receive end, also with independent audio / video frame as unit, decoding to form audio / video flow for display or storing as file. This invention can transmit any high code rate data in bandwidth-limited network, and displays audio / video content real-time while stores file as requested format.

Description

technical field [0001] The invention relates to a data transmission method, in particular to a network transmission method of audio / video data. Background technique [0002] With the development of digital technology and network technology, people's demand for network transmission of audio / video data is also increasing. The network transmission of audio / video data has many advantages, and is widely used in fields such as television broadcasting, military affairs, communications, telecommuting, distance teaching, and Internet value-added services. But at the same time, because the data volume of audio / video files is often very large, especially high-quality audio / video files, and the network bandwidth is limited, in order to realize its transmission on the network, or as much as possible for data transmission network bandwidth, or improve audio / video data compression and data transmission technology. The former needs to invest a lot of network equipment costs, and it is imp...
