Abstract: The present invention relates to an video displaying apparatus for an internet set top box, which has a video memory for storing pixel data corresponding to a scanning line of a TV signal, and a method for scrolling screen fast. The video displaying apparatus comprises a memory; a data processor for converting a received video signal into pixel data and storing the pixel data in the memory; four FIFO memories for temporarily storing pixel data of a scanning line of a TV signal from the memory; a MUX for sequentially selecting the FIFO memories one by one and outputting the pixel data from the selected FIFO memory; an RGB converter for converting the pixel data through the MUX into RGB signals, a Y/C converter for converting the RGB signals into composite analog signal consisting of luminance and chrominance signals; and a controller for controlling the data movement from the memory to the FIFO memories and output selection of the MUX.

Abstract: A control apparatus of a real time counter for a video cassette recorder. This apparatus comprises a CLOG detection section having an envelope detector, a comparator, and a low-pass filter for detecting a CLOG signal to judge whether a signal exists on the videotape; an ATF detection section having an ATF detector, an analog-to-digital converter, a band comparator, a shift register, and a state detector for detecting an automatic track following signal, an AND gate for performing a logical product between the CLOG signal and the automatic track following signal and an REC instruction; and a counting section having a switch which is for controlling a real time counter using the output, or a control signal of the AND gate. This apparatus accomplishes the accurate control of a counting by using an automatic track following signal as well as the CLOG signal.
