In this paper, based on the FPGA and with a video dedicated A / D converter chip, LVDS coding chip, the design and implementation of a SD(standard-definition) analog video signals to HD(high-definition) digital video signal converter. First, input SD analog video into digital video signals meet the ITU-BT656 standard. Then use the FPGA with the video processing chip and DDR do some corresponding processing to achieve high-definition digital video output. After the actual test, the converter output signal of the image quality is well, meets the design requirements, and to verify the effectiveness of the program.

Transition is a natural law which means the things gradually developed from one stage to another. It comes to be a natural and logical thing when it moves towards the right direction. In this paper, we will take the nuclear power station video conference room contribution as an example to comb the management of video conference room from three parts: the limitations of “Standard-Definition”, the excellence of “High-Definition” and the necessity of transition. It also discusses the feasibility of nuclear power station’s High-Definition video conferencing system.

This paper proposes a scheme of H.264 high-definition encoder/transcoder . The system is based on ASIC. Application-specific high-definition encoding/transcoding chip, software control module, HDMI interface, analog video/audio input interface and ASI input/output interface ,etc. are discussed in detail in this paper. The system also provides the Ethernet interface, which is used for real-time monitoring of coding/transcoding system . The proposed scheme with the property of good real-time and low cost accord with the need of high-definition digital TV front-end system.
