UCL Indexing and Transmission Scheme in Data Broadcasting

UCL(Uniform Content Locator)build a bridge between writer and reader for better understanding,which is a key technique for data processing such as receiving quickly,information filting,service intelligently and actively in data broadcasting.The methods of UCL-W indexing and multiplexing are put forward for Web service in data broadcasting,and the techniques of multimapping and bistage multiplex are studies in this paper.And then the flow diagram of the data processing,including data gather,UCL indexing,multimapping,multiplexing,data format transform,modulation,are figuir out.The experiment result shows that the creative methods and the new designs are correctly and efficiency based on DVB-C network.
