In general, multimedia is a part that is applied to the rapid growth of the computer industry as well as to transmit the presentation information through one or more media, as well as to more applications. Multimedia is a combination of features of media, and in addition, it uses multimedia to present a lot of business information to consumers. In other words, multimedia is a type of communication between a user and various types of information through a data processing system such as a personal computer, and other types of media may be combined to communicate.

Multimedia applications are also applications that use other forms of communication within a single application. For example, a multimedia application may communicate data with a user through a computer or various media via audio and video signals simultaneously. Such multimedia applications are typically bit intensive, real time, highly demanding, and require large processing power in data processing systems.

Users can, for example, access multimedia in the form of videogames or movies via adapters and communication links on digital video disks. Multimedia is also popular on the Internet, and many web sites provide multimedia to users who visit the web site.

The above-mentioned multimedia generally uses a multimedia adapter to mutually communicate data between media or between media and a user through multiplex / demultiplex, as shown in FIG. 1. As such, the multimedia adapter to which the multiplex / demultiplex is applied is implemented as a wireless media adapter using the Industrial Scientific Medical (ISM) band (2.4 to 2.4835 GHz). That is, when the wireless media adapter is implemented in a one-to-one manner, the wireless media adapter is complexly connected by one-to-one wired connection between other media devices located in a short distance, and when the distance between media devices is short, the frequency is too high. It acts as a major cause of destabilization of radio communications.

Subsequently, the decompression is performed by providing the received compressed digital data to the codec unit 9 through the wireless network S1 and receiving the compressed digital data to the DAC 10. After converting the signal into an analog signal, the decoded analog signal is decoded into an analog video signal and a digital signal through the demultiplex 11 and provided to the multimedia receiver 12.

As described above, in order to communicate data through the wired S2 and the wireless network S1, mutual communication must be performed through a compression and decoding process using the multiplex 2 and the demultiplex 3, 11. do. However, the multimedia adapters to which the multiplexes 2 and the demultiplexes 3 and 11 are applied still have the above-mentioned problems of the complexity due to the wires and the instability of the radio wave communication due to the high frequency, and are particularly expensive, In terms of mass production, the price of the material is inevitably set at a high price due to the increase in the price of the material, and there is a problem in that the economic burden on the user side.
