A remote thin client system for real time multimedia streaming over VNC
This paper proposes a remote thin client system for real time multimedia streaming over VNC. A remote frame can be split as two parts, i.e. high motion part and low motion part, and transmitted through the Internet from servers to clients according to the proposed hybrid RTP protocol.

| description | This paper proposes a remote thin client system for real time multimedia streaming over VNC. A remote frame can be split as two parts, i.e. high motion part and low motion part, and transmitted through the Internet from servers to clients according to the proposed hybrid RTP protocol. A Dynamic Image Detection Scheme (DIDS) is proposed to automatically detecting the high motion part of a frame with only 1% of extra CPU loading. In addition, an Error Detection Scheme (EDS) and a Dynamic Bit-rate Control Scheme (DBCS) are also proposed to ensure good video streaming quality under bandwidth limited applications. This paper also proposes a linear time BU-level rate control algorithm to ensure the proposed DBCS can be finished in real time. The proposed algorithm reduces the computational complexity from O(n 2 )to be O(n). By using the proposed thin client system, we can achieve about 22 fps of real-time SIF video streaming with good video quality under 32 KByte/s of bandwidth limitation, which speeds up about 172 times in remote frame display when compared to pure VNC. |
