Abstract:
This paper designs Broad-Storage TV(BSTV) system on the hardware platform of Cable Television(CATV) broadcasting network structured in laboratory. Uniform Content Locator(UCL) information is marked on the programs at the services. The storage processes are added to the clients and the clients utilizes the marked information to locate the program contents. The system realizes broadcasting transmission of double-way digital TV programs and incremental download at the client. Experimental results demonstrate the feasibility and validity of BSTV system structured on the platform of CATV broadcasting network.
