Digital TV shows program unauthorized can be resolved by calling and going through the operator.
Digital TV, also known as digital TV or digital TV, is the type of TV that uses digital TV signals from the studio to the launch, transmission and reception of all aspects of the system or to the system all the signal propagation is through the binary digital stream consisting of strings of 0, 1 digits, as opposed to analog TV. Its signal loss is small, good reception.
Digital television is a program from the program acquisition, program production, program transmission until the user end of the end-to-end system to digitally process the signal, based on the DVB technical standards of broadcasting and "interactive" digital television. The use of advanced subscriber management technology can be the quality and quantity of program content to do the best possible and bring more program choices and better program quality for the user, the digital television system can transmit a variety of services. A signal transmitted within a communications system in which the physical quantities carrying the information are discrete in time and take discrete values is called a digital signal, which is a digitized representation of a discrete-time signal, usually obtainable from an analog signal.
The propagation rate of digital television is 19.39 megabytes per second, and the delivery of such a large stream of data ensures the high definition of digital television, overcoming the inherent deficiencies of analog television. At the same time also due to digital TV can allow the simultaneous existence of several standard signals, each digital channel can be divided into several sub-channels, so that both a large data stream - 19.39 megabytes per second, China vigorously pursued by the TV analog signal to digital signal conversion.
Digital TV is a product of digital information technology, featuring digitization and interactivity, which integrates TV transmission methods with information technology. Compared with the viewing of traditional analog television, the high precision of digital technology makes digital television both from the clarity of the picture and the accompanying sound effect has been greatly improved.
