SYNCHRONOUS VIDEO TERMINAL USING ISDN VIDEO CODEC AND METHOD FOR CONTROLLING DATA STREAM USING THE SAME

摘要

1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a synchronous video terminal device using an image encoder for an integrated information communication network (ISDN), a data flow control method thereof, and a computer-readable recording medium having recorded thereon a program for realizing the method.;2. The technical problem to be solved by the invention;The present invention continuously generates a network synchronization clock signal required for an ISDN video encoder from a synchronization signal such as a next generation mobile communication (IMT-2000) network, and continuously provides a data amount of a buffer according to a transmission bit rate. A synchronous video terminal device using a video encoder for an integrated information communication network and a data flow control method thereof, which prevents loss and delay of transmission / receiving audio / video compressed data by adjusting, and a computer-readable recording recording a program for realizing the method. To provide media.;3. Summary of Solution to Invention;The present invention provides a video encoding means for an ISDN which supports multiplexing and demultiplexing according to a given standard for compressed audio / video data and performs compression and reconstruction on audio / video data; Transmission data storage means for storing audio / video compressed data output by the video encoding means for the ISDN; Received data storage means for storing the received audio / video compressed data and providing the same upon request of the video encoding means for the ISDN; Synchronizing signal generating means for generating a network synchronizing signal of the video encoding means for the ISDN by using a transmission / reception frame synchronizing signal and a reference clock; And a transmission / reception timing interrupt signal using the transmission / reception frame synchronization signal, reads data from the transmission data storage means when the transmission / reception timing interrupt signal is generated, configures the transmission data into a wireless transmission frame, and transmits the received wireless reception frame. Central processing means for decomposing and storing the received data storing means.;4. Important uses of the invention;The present invention is used in the next generation mobile communication.
