| Audio and video codecs and transmission is an important part of the military equipment. With the rapid development of the Informatization Construction for C hina’s military equipment, higher requirements for the corresponding and affilia te products are put forward. However, the traditional Audio and video codecs and transmission system generally consists of some equipments that only have a single which often function,prone to "loss" phenomenon, leading to the Transfer screen’s "Huaping" phenomenon, and it’s too hard to adapt to complete the test in a field environment. Therefore, according to specific develop ment requirements of a military project, this topic designs and implements an audio and video codecs and transmission.First of All, in terms of the background and significance of the research, this topic introduce the composition of the military Audio and video codecs and transmission, it is background, it’s development and the development trend of the next generation of military audio and video codecs and transmission system.Secondly, this topic summarizes involved background technology knowledge, including audio and video codecs, virtual instrument system and interchangeable virtual instruments technology. Thirdly, through the analysis of specific test requirements, this topic design audio and video codecs and transmission system.In the hardware design, this topic mainly discusses the hardware circuit design of the interface adapter. In the software design, this topic mainly discusses audio and video codecs and transmission system. Finally, this system have been applied in the field more than once. It turns out that this system is able to test the audio and video codecs.It has important practical significance for the improvement of the maintenance and logistics of modern weapon equipments and the enhancement of battle effectiveness. |
