Abstract

Abstract:

We use wavelet compression method based on high efficiency at lower network bandwidth conditions for transmission D1/720P/1080P high-definition
monitor screen, to achieve equatorial guinea Jilin Transmission and Distribution International working environment for realtime video monitoring. The system can monitor the use of network bandwidth according to the specified requirements, a circulating memory storage function. The wavelet coding techniques have their own independent encoding and decoding specification, with high security and confidentiality, can be transmitted D1 20FPS next image transmission 200 kbit/s delay is less than 1 s, compared to the international standard H.264 technology can save bandwidth of less than 60%.

Key words: wavelet transform, image compression, video transmission
