The novel information sharing architecture, Information Sunshine, is presented in the paper. It is collisionless, and based on data broadcasting networks other than bi-directional TCP/IPs. Two core concepts of the Information Sunshine idea are Data Stream Environment (DSE) and Personal Demanding Code (PDC). The DSE means that several hundreds gigabytes stream to each household everyday utilizing the great data push .capacity of DVB, and then the nationwide flow of the high speed data stream forms a digital environment. The data flux is so great that thousands of papers, periodicals, Web Server and courseware could be rolling broadcast for several dozens times per day. The PDC code helps each user distinguish favorite contents from broadcasting data stream and intercept them into local hard disk. After storing, users can locally interact with the information without remote connection requirement. Only single-way broadcasting network required by the Information Sunshine architecture, so it is low cost and will drastically eliminate inherent bandwidth collision of bi-directional IP architecture.
