摘要: In a video signal encoding method and apparatus, transmitting method, the recording medium, hierarchical of image data implies problems in that compressing efficiency is reduced as number levels increased quality degraded particularly lower-level images. After D31, D33, D35 at respective are generated by an average value calculation, pixel which can be restored arithmetic operations using adjacent higher their own thinned, higher-level compressively coded with larger numbers quantization bits. Since amount to transmitted thinning, it possible suppress increase pixels transmitted, caused structure. addition, assigned bits, so degradation due errors
