“…As known from Figure 1,multiplex is the information package and arrange for audio, video, data, ESG and so on, and demultiplex is actually the reverse process of multiplex, namely the received information is analyzed to video, video and control information, other parameters and audio/video files , that is according to multiplex's frame structure and combination way , as shown in Figure 3 [4]- [6] . Supposing n X (n = 0,1,2,3 ……) represents all states for the Nth frames of broadcast channel, when demultiplexing control information in Figure 4, we call the state is P, when demultiplexing service data, we call the state is T, the formal language description is as follows: Figure 4 is the state conversion chart of a broadcasting channel frame demultiplex, when state transition, its input is code stream which waits for demultiplexing, as long as the input stream meets the conditions, it will enter the next state, and will be accepted by the next state.…”

Through analysis the multiply frame structure of China Mobile Multimedia Broadcasting (CMMB) system, design a method of the terminal demultiplex. This method makes use of the finite automaton theory to carry on the classification for code stream received by terminals, induced the status of the various relevant information and proposed transformation conditions between these states, designed a finite automaton. After achieved by C code, the finite automaton can process code stream very good received by terminals, when the demultiplex completed , various kinds of useful information can be preserved for other modules.

“…A subjective criterion for good viewing reception has also been developed in [8] for DMB: 7% freeze frames in 20 seconds were considered the maximum rate, while in our paper, the maximum was 5% in 40 seconds (or 80 samples). Our criterion can be considered somewhat more restrictive.…”

“…In [3][4][5][6][7], performance of DVB-H systems is evaluated. A subjective criterion for good viewing reception has also been developed in [8] for Digital Multimedia Broadcasting (DMB). In [9], the performance degradation of OFDM signals due to Doppler spreading in mobile radio applications such as 802.11a and DVB systems is investigated.…”

DVB-H networks allow high data rate broadcast access for hand-held terminals. A new method to determine the range of good reception quality of such a DVB-H network will be investigated in this paper. To this end, a new subjective criterion is proposed, based on the viewing experience of the users. This criterion is related to the percentage of valid reception. A comparison with existing criteria, based on measured signal strengths, is also made. The ranges are determined for mobile reception inside a car. The influence of the MPE-FEC rate and the modulation scheme on the range is also investigated, enabling wireless telecom operators to select optimal settings for future networks.

Developed from Digital Multimedia Broadcasting (DMB), DMB+ changes the application focus fundamentally. The plus symbol "+" indicates that DMB+ is no longer for digital radio/videos, instead it works as a general data transmission technique. The merits of wireless transmission, broad coverage, high quality, information security and low building/maintenance cost make DMB+ suitable for a wide range of applications with numerous terminals and users, such as public information release, alarm and administration etc. The concept of DMB+ base station enables DMB+ to be used in building independent networks and for remote control and management, as well as for Industry 4.0. DMB+ will access into a new field that till now has been dominated by communication techniques, will open a huge commercial opportunity.
