| Abstract: | Based on ARM embedded hardware platform and embedded Linux operating system,using the Qt's socket,Qt's signal/slot mechanism,block-based image data algorithm and the feedback control mechanism,a transmission scheme of embedded image data is designed and implemented.In this scheme an exception handling mechanisms are also used to ensure efficient and reliable transmission.The scheme provides a useful reference model for embedded web application development.Finally,a running example of the system is presented... |
