Abstract: PURPOSE: An automatic image control method of an LCD monitor is provided to display an optimum screen in accordance with RGB video signals input differently by a video mode. CONSTITUTION: The automatic image control method of an LCD monitor comprises the steps(S10,S11) of reducing the memory addresses of a frame buffer if data are absent in a start point(A,A'). Then, the PLL clock frequency of an AD converter converting RGB signals into digital signals is reduced to control the gap between start and end points if data are absent in the end point. Next, the gap between the memory addresses of the frame buffer is controlled by varying the times writing from a line buffer to the frame buffer from an XVGA mode time to an SVGA mode time if the data are absent in a start point(A') or an end point(A).

Abstract: PURPOSE: A method for establishing the initial access synchronization of a satellite communication system using a DS/CDMA system in a return link is provided to increase the data transmission efficiency and reliability of packets by extracting the deviation information of a carrier wave frequency and a timing using an initial access time slot before real signal information and traffic data are transmitted and by compensating it in a terminal office. CONSTITUTION: A terminal office receives reference timing information periodically sent from a central office through an MPEG-2 transport stream(201,202) and generates a transmitting timing dependent on a return link channel structure(203). The terminal office sends an initial access CDMA burst at an initial access time slot(204). The terminal office drives a timer and transits to a standby state to receive a response message from the central office(205). A receiving part in the central office acquires PN code synchronization using a preamble of the initial access CDMA burst and extracts a frequency error(207). The receiving part calculates a timing deviation value and a frequency deviation value(208) and transfers them to a management part with demodulated data. The management part reconfigures them into an IP packet to transfer them to the terminal office(209) and transfers the IP packet to a transmitting part. The transmitting part multiplexes the IP packet into an MPEG-2 transport stream and sends it to the terminal office(210). Receiving the response message before the timer operation ends, the terminal office releases the timer and executes the next operation(211).
