【摘要】：在视频通信发展史上,最开始的视频通信是以模拟信号输出方式,而发展到今天则是都是以数字信号为主。而在DSP和FPGA这类高速的数据运算芯片横行的今,对大量的数据进行快速,高效的运算是一件很简单的事。但是,这类芯片却普遍有着运算能力强,控制能力差的特点,在人们对于视频通信多功能性要求越来越高的今天,它们已经满足不了现代技术的发展,必须采用新的技术和手段来解决这个问题。 本文设计了一种嵌入式视频通信系统,选取德州仪器公司的芯片以及其配套的相关软件技术平台来实现其功能。采用了TM320DM365这款芯片,’该芯片内部集成了一个ARM内核和相关的视频编码处理器,配上相应的外设,完成了系统的硬件构架。而在软件方面采用了嵌入式Linux系统,完成u-boot, kernel等编译和移植,并详细的阐述了如何使用达芬奇技术实现相关的软件功能,如视频的采集,编码压缩,和网络传输。最后对整个系统进行了测试,实现了论文要求的基本功能。 本系统采用达芬奇公司一系列配套的软件开发技术,它包含的技术使得开发者更加便捷和快速的实现二次开发,而且它能满足现今市场对嵌入式视频通信的一切要求,而且具有低功耗,造价低等优点,在市场上有着极大的发展空间好良好的市场前景。因此,基于达芬奇技术平台开发的视频通信系统有着极高的实用价值。
[Abstract]:In the history of video communication, the first video communication is analog signal output, but today it is mainly digital signal. In the high speed data processing chip such as DSP and FPGA, it is very simple to calculate a large amount of data quickly and efficiently. However, these chips generally have the characteristics of strong computing power and poor control ability. Nowadays, when people are demanding more and more multifunctional video communication, they can not meet the development of modern technology. New technologies and means must be used to solve the problem. In this paper, an embedded video communication system is designed. The chip of Texas Instruments and the related software platform are selected to realize its function. The TM320DM365 chip is adopted. The chip has integrated a ARM core and a related video encoding processor, with the corresponding peripherals, and completed the hardware architecture of the system. On the other hand, embedded Linux system is used to compile and transplant u-boot. kernel and so on. How to use Leonardo da Vinci technology to realize related software functions, such as video collection, coding and compression, and network transmission is described in detail. Finally, the whole system is tested and the basic function of the thesis is realized. This system adopts a series of software development technologies of Leonardo da Vinci Company, which make developers realize secondary development more conveniently and quickly, and it can meet all the requirements of embedded video communication in the market. With the advantages of low power consumption and low cost, it has great development space and good market prospect. Therefore, the video communication system based on da Vinci technology platform has high practical value.
