摘要
A new dual-mode transmission networks （DMTN） based on broad-storage architecture for digital television （DTV） is proposed, in which the primary TV network is superimposed by a complementary framework based on broad-storage TV （BSTV）. The necessity of congregating hot TV resources is discussed via analyzing the scale-free properties in DMTN. The self-organized parallel broadcasting technology （SPBT） and the uniform content locator （UCL） are studied to utilize availably transmission channels and to help consumers to communicate with each other expediently. Experimental results show that DMTN can provide not only traditional TV services on schedule, but also digital interactive TV services on demand by using a single channel.
