A setting apparatus of an antenna for satellite broadcasting in a satellite broadcasting system includes a receiving device coated with a fluorescent material whose color varies depending on a level of a voltage applied thereto, for receiving a satellite broadcast signal; and a controlling unit coupled to the receiving device for applying a driving power source to the fluorescent material of the receiving device, depending on a level of the satellite broadcast signal received in the receiving device.

Setting apparatus and method of antenna for satellite broadcasting

A phase shift correcting apparatus of a sync detector in a satellite broadcasting reception system corrects a phase shift of 180.degree. which makes output data after demodulation be absolutely different from an original data such that 47 sync is phase-shifted by 180.degree. to be detected as B8 sync data. For this, the number of B8 data and 47 data of input data is counted in a comparator and a counter to determine whether the phase shift of 180.degree. occurs or not, and data involving the phase shift is converted to have a normal data value when it is determined that the phase shift occurs, thereby improving reliability of a satellite broadcasting receiver and solving the problem of the different data output.

An image shake compensation circuit comprising a motion information detector for detecting motion information based on the occurrence of an image shake when the image shake occurs in an encoded video signal, a shake compensator for obtaining a start display position of an image of a present frame according to the motion information detected by the motion information detector, and a decoder for decoding the encoded video signal, correcting a display position of the image of the present frame in response to an output signal from the shake compensator if the encoded video signal has previously been compensated for the image shake and compensating for the image sake if the encoded video signal has not previously been compensated for the image shake.
