Abstract
본 발명은 양자화된 블럭내 양자화 값을 소정 갯수의 쌍으로 결합하여 결합된 양자화 값들에 대한 부호화를 행하는 영상 신호 부호화 장치에 관한 것으로서, 2차원 DCT 방식에 의하여 변환된 DCT 계수들을 양자화하는 양자화부와; 양자화부에서 양자화 된 블럭의 양자 값을 지그재그 스캐닝 순서로 소정 갯수의 양자화 값들을 서로 쌍으로 결합시키는 결합화부와; 결합화부에서 형성된 쌍들을 지그 재그 스캐닝하여 쌍들에 대한 줄 길이 부호화를 행하여 쌍을 이루는 양자화 값 모두가 0값을 갖지 않는 쌍들 각각에 대한 양자화 값을 소정의 계수 값으로 부호화하여 송신하고, 연속적으로 쌍을 이루는 양자화 값이 모두 0인 쌍들에 대한 런 값을 부호화하는 줄 길이 부호화부와; 줄 길이 부호화부의 런 값을 가변 길이 부호화하여 송신하는 가변 길이 부호화부를 구비한다.The present invention relates to an image signal encoding apparatus for encoding quantized values by combining quantized values in a quantized block in a predetermined number of pairs, the quantizing unit for quantizing DCT coefficients transformed by a two-dimensional DCT scheme; ; A combiner for coupling a predetermined number of quantization values to each other in a zigzag scanning order by quantizing the quantized values of the blocks quantized by the quantization unit; Zig-zag scanning the pairs formed in the combiner to perform line length encoding on the pairs, encoding and transmitting quantization values for each pair whose pair quantization values do not have a value of zero with a predetermined coefficient value, and successively pairs A line length encoder for encoding run values for pairs of all quantization values of 0; And a variable length encoder for variable length coding the run value of the line length encoder.
즉, 본발명은 양자화부의 양자화 값을 쌍으로 묶은 상태에서 줄 길이 부호화를 행함으로써 송신되는 영상 신호의 비트 수를 감축할 수 있는 효과가 있다.That is, the present invention has the effect of reducing the number of bits of a video signal to be transmitted by performing line length coding in a state in which quantization values of the quantization unit are paired.
