Operation of mobile TV technology. Core technology. For mobile TV technology, the very early abroad have begun to research. Japan in 1999 by a terrestrial broadcast digital television standard ISDB-T in Europe in 2002 began to study this standard, and in February 2004 by the DVB-H standard. South Korea in February 2003, clearly stated, "Digital Multimedia Broadcasting", and support standard named DMB, The country of Chinas mobile TV standard be introduced before the end of 2006. In October, the State Administration of Radio, Film and Television issued recommended standards: of STiMi technical standards. The formulation of these standards, to provide a basis for the development of mobile TV. It is for the supplementary installation method of perfect cell phone jammer on the outer wall.
At present, the core technology of mobile TV, is the network operator implementation. These technologies or standards, mainly in three ways: two-way communication that can use the mobile network, to provide users with personalized service; convenient right to business monitoring, management, accounting and control; do not change the phone hardware platform network bandwidth is limited, and could easily lead customers to compete for resources; low image resolution, image quality is affected by the impact of network bandwidth. Ground-based radio and television technology. Basically completed ready for commercialization. Does not exist to bandwidth restrictions and limits the number of users, high image quality; low sensitivity to the user, the capacity of the unexpected and emergency events. Usually there is no uplink, it is difficult to achieve the users personalized service. Adjust the distance between positions of installing perfect cell phone jammer .
Difficult to identify, control, interaction, billing and positioning services; terminal a digital television receiver unit must be increased. Have been commercialized for one year the use of satellites for mobile video broadcasting services more efficient; the satellites wide coverage. Personalized and interactive subject to certain constraints; terminal circuit module must be increased to be able to receive satellite TV signals. Based on the mobile communication network. In this way is actually through the mobile communication network using streaming media technology to achieve mobile TV program delivery, as well as the user on demand. The United States and Chinas mobile operators launched mobile TV services rely on the existing mobile network. Perfect cell phone jammer is hung inside the plant.
