DTV-34A 34Mbit/s彩色数字电视传输设备由北京邮电大学无线电工程系图像技术研究所研制,并于1991年4月正式通过了邮电部“七五”科技攻关项目的国家级鉴定。在“七五”基础上,科研人员又进行了二次开发,用了两年的时间把科研产品实用化,推出了型号为DTV-34A的实用型产品。与科研设备相比,实用型产品从设计原理、体系结构、系统功能到外型都有根本上的改进,集成度、稳定性和图像传输质量都有很大的提高。
The DTV-34A 34Mbit / s color digital television transmission equipment was developed by Institute of Image Technology, Beijing University of Posts and Telecommunications Radio Engineering and formally passed the national appraisal of the Seventh Five-Year Scientific and Technological Project of the Ministry of Posts and Telecommunications in April 1991. On the basis of the Seventh Five-Year Plan, researchers conducted a second development and spent two years putting the scientific research products into practical use. The DTV-34A was launched as a practical product. Compared with scientific research equipment, practical products from the design principles, architecture, system functions to the appearance of a fundamental improvement, integration, stability and image transmission have greatly improved the quality.
