The Design And Implementation Of A Prototype Telemedicine System Based On Web Service

Telemedicine, including long-distance diagnosis of a new medical methods and technology development, he is in long-distance diagnosis in recent years on the basis of developed, the rapid development of computer network technology for the implementation of telemedicine technology to provide reliable technical support. The expert doctors and patients between the time and space constraints to the adoption of "telemedicine" technology leap for the patients. To design and develop distance telemedicine system based on streaming media is discussed in this thesis. The relative technology has been researched and the system has been realized with software.In this study, a digital watermarking method be used in H.264 video transmission is proposed. At the encoder, for an H.264 frame, the important data for each macroblock are extracted to become the unique watermarking for this frame then embedded it into the frame by a relationship of transform coefficients for differing transforms. At the decoder, if the extracted watermarking is correct, then can know that the important data of macroblocks in the frame will be trusted. If not, then can the mathematical method will recover the error approximately.This thesis expounded the Web Service Technology firstly, and then discusses the limit of the TCP, RTP/RTCP protocol and RTP payload format for H.264 visual streams. Finally, a feasible project of distance telemedicine prototype system is designed. It depends on .NET technology. The components, such as the real-time sample, video encoding, video decoding and display, are programmed and tested.
