Title Design of Gigabit Ethernet transmission program for real time video data
Abstract
With the rapid development of modern electronic technology, digital transmission system has become increasingly complex and transmission amount of the data in the system will become bigger and bigger. Especially a similar to the emergence of large outdoor LED screen video system, which makes the system between each subsystem of the internal communication become more and more, the data in the transmission process of a real-time, high efficiency and stability have higher requirements.
In this subject, according to the requirements of the use of the VC software design and computer principle and other related knowledge, but also to understand
The standard and protocol of the DSP gigabit network interface are studied, and its working mode and programming method are also studied.. A gigabit network communication program between PC and development board is designed..
So in this paper by using VC + + as the software development platform, combined with the socket (socket) under the UDP protocol to send, a real-time video transmission system based on Gigabit Ethernet is designed by design and programming techniques. First under Windows platform based on socket of the basic theory and method of network programming for the understanding and study of, and through comparison of the characteristics of all kinds of network protocols, choose a suitable protocol for the transmission of this topic; on socket (socket) based on VC + + the UDP send receive program is programmed.
Keywords: real-time video transmission VC++ Ethernet socket (Socket) UDP
