本文提出一种符合CCITTH.261建议的会议电视的软件和硬件设计,对其中的几个关键技术问题,如系统工作模式,速率控制,自适应内插等作了较为深入的探讨,提出了切实可行的解决方法。本文研究的重点是专用集成片功能以外的系统控制等部分。计算机模拟表明:该设计的有关技术是有效的。压缩后的图像质量可以满足会议电视的要求。
This paper presents a conformable CCTVTH.261 conference television software and hardware design, which several of the key technical issues, such as the system operating mode, rate control, adaptive interpolation made a more in-depth discussion, put forward a practical Feasible solution. This article focuses on the part of system control other than ASIC functions. Computer simulation shows that the design of the relevant technology is valid. Compressed image quality to meet the requirements of the conference TV.
