     2-3 풀다운의 수법을 쓰는 텔레시네 변환에 의해 얻어진 비디오 신호에 대해서 효율이 양호한 부호화가 가능하다.

Title: Variable bit assigning device in audio
Inventor: KIM SUNG-BONG
IPC: H04B7/24
Filed: 1993-09-28
Granted: 1997-12-01
Abstract: The present invention provides a variable bit allocating system according to kinds of audio broadcasting which restricts the compression ratio of the audio data and the band according to the kinds of audio broadcasting and the tone quality, and allocates the excess of the remaining bit number to video data. The inventive system includes a high speed fourier transformation and threshold computing part computing a masking threshold that does not sense noise according to the broadcasting mode selection information; a bit allocating part which allocates bits with respect to each divided band signal within a range where quantizing noise does not exceed the masking threshold; a first quantizing part quantizing divided band signals in response to the bit allocating part's output; a second quantizing part quantizing adaptively video data; a fullness computing part computing fullness, the degree of storing video data in a buffer; a multiplexing part varying and multiplexing the bit stream of the audio data and video data processed according to the broadcasting mode.
