This design will contribute to the growing multimedia movement in the current telecommunication networks. By reducing the bandwidth of the high-quality audio bitstream this module has potential use in variety of applications. The MPEG algorithm itself is already widely used in Europe with the new digital broadcast systems and the MPEG video is breaking through the multimedia PC market along with the Digital TV market. The exponential growth of Internet and the World Wide Web pushed the limits of today's networks and the need for bandwidth to incorporate the multimedia signals is growing. The compression methods are significant in bridging the gap between the quality of information and the costly communication lines. With its rate of 128 kbits/s the MPEG Audio Decoder Module is even suitable for use in the new ISDN networks, meaning CD-quality sound over telephone line. In addition this module can be used as a playback device for local or remote music archives. However, the real gain of this device is when it is used in a multitasking environment such as Linux, Windows NT/95, OS/2 etc. This will allow playback of a high-quality audio sounds with minimal loading of the CPU making it available for other tasks.
There are some aspects of the design which can be greatly improved in the future. The program which was used to send the binary file to the decoder module should have been interrupt driven or implemented on a computer with pre-emptive I/O scheduling, or at least the MPEG file should have been entirely loaded into ram or buffered so that reading the file from the hard disk would not have affected the bitstream rate. If these two corrections to the software implementation were made, it is highly probable that the bitrate would be more consistent. In addition, by making appropriate changes in the design and the program, this system would be able to support any input bitrate between 64-448 kbits/s depending on the application.
