摘要： A frame synchronization method and apparatus for use in a digital communication system utilizing OFDM method are disclosed. The frame synchronization apparatus comprises a phase calculator for calculating phase values of TPS pilots within a symbol according to in-phase and quadrature-phase channel signals received from a transmitting side; a D-BPSK demodulator for performing D-BPSK demodulation for the phase values of TPS pilots supplied from the phase calculator and outputting the TPS pilots within the demodulated symbol; a control signal generator for comparing the demodulated TPS pilots with each other and outputting a control signal according to the compared result; and frame synchronization unit for confirming a sync word position according to the control signal supplied from the control signal generator and outputting a frame sync signal. Hence, frame synchronization can be achieved by using the synchronization word inverted at each frame in one TPS block without the need to increase the size of hardware.

摘要： Disclosed are an image processing system for displaying character information and a method for the same. According to the image processing system, character information is input by a user, and the input character information is combined with received image and audio signals to generate Transport Streams (TSs), which are transmitted to an image display. The image display decodes and outputs the received TSs. Accordingly, when it is necessary to inform urgent public notices within a predetermined region such as a public place, these notices may be rapidly transmitted to be displayed as character information.

摘要： A frame transmission method performed by a transmitting end in a video reproduction system having the transmitting end for wirelessly transmitting frames and a receiving end for receiving the frames transmitted from the transmitting end and reproducing a video signal. The transmitting end receives information about a state of a wireless environment from the receiving end, determines the frames to be transmitted to the receiving end in consideration of the received information about the wireless environment state, and transmits the determined frames to the receiving end. The receiving end measures the state of the wireless environment by judging whether an error exists in the received frames and transmits the measured state of the wireless environment to the transmitting end. Accordingly, different frames can be transmitted according to the state of the wireless environment.
