MPEG-4 CODING MODE SELECTION METHOD FOR REAL-TIME STREAMING SERVICE

摘要

In the real-time streaming service coding mode selection method according to the present invention, in the real-time streaming service of video-on-demand (VOD) using a wireless Internet network, the packet loss rate (PLR) that can know the error situation from the receiving terminal side to the receiving terminal side Receiving information; And selecting an encoding mode of the encoder based on the packet loss rate (PLR) information.;According to the present invention, in the case of streaming transmission using the wireless Internet, in consideration of the characteristics and complexity of the MPEG-4 coding mode, the MPEG adaptively according to the packet loss rate (PLL) information that can know the error situation on the receiving terminal side By selecting the -4 encoding mode, it is possible to improve the error detection and error concealment performance at the terminal, thereby improving the image quality, and ultimately, reducing the amount of computation at the terminal and providing a better real-time video image service to the user.
