AI Technical Summary

Problems solved by technology

[0002] The currently applied broadcasting system mainly adopts the broadcasting system of the analog broadcasting system, that is, the existing frequency modulation (FM) or amplitude modulation (AM) broadcasting channel, because the channel of the analog broadcasting system is fixed and the bandwidth is small, it can only be used for transmission Sound information, and one channel can only accommodate the transmission of one program information. When more than two channels are close, interference between the two channels will often occur; plus the coverage of analog broadcasting is small, when receiving When the device at the end is at the boundary of the coverage area, due to signal attenuation, the signal received by the receiving end often contains a lot of noise, or even an intermittent signal; for modern communication technology, in order to meet the needs of human knowledge, Designing a new delivery system has become increasingly important
[0003] In addition, for the current broadcasting ecology, most of them are one-way data transmission. For the modern life of high-speed information transmission and exchange, one-way information transmission is not easy to integrate the opinions between the transmitter and the receiver. The way of transmission has gradually declined; in addition, as far as the current mode of transmitting multimedia information by wireless transmission is concerned, although it can transmit multimedia information, there are still areas for improvement in terms of transmission speed, range and data volume

Embodiment Construction

[0030] Relevant feature and implementation of the present invention, hereby cooperate with figure and describe in detail as follows with best embodiment:

[0031] A data transmission and data presentation method applied to digital broadcasting (DAB), through data conversion and packet technology transformation, the data is sent from the transmitting end to the receiving end through the digital broadcasting (DAB) packet transmission technology method; through the operation of this method, in order to achieve the purpose of transmitting the data at the transmitting end to the receiving end for presentation.

[0032] Therefore, in order to achieve the above-mentioned purpose, the method of the present invention can be divided into two parts, data transmission and data presentation; now, the data transmission part will be described with the data transmission operation flow chart of the present invention shown in FIG. 1 .

[0033] As shown in the figure, first, when the transmissio...

Abstract

The data transmission and data reproduction method for digital broadcast transmits data from the transmitting end to the receiving end and reproduces data in the receiving end by means of data converting and envelop converting technology.

Description

technical field [0001] The invention relates to a data transmission method, in particular to a data transmission and data presentation method applied to digital broadcasting (DAB). Background technique [0002] The currently used broadcasting system mainly adopts the broadcasting system of the analog broadcasting system, that is, the existing frequency modulation (FM) or amplitude modulation (AM) broadcasting channel, because the channel of the analog broadcasting system is fixed and the bandwidth is small, it can only be used for transmission Sound information, and one channel can only accommodate the transmission of one program information, when more than two channels are close, there will often be interference between the two channels; plus the coverage of analog broadcasting is small, when receiving When the device at the end is at the boundary of the coverage area, due to signal attenuation, the signal received by the receiving end often contains a lot of noise, or even...
