蓄積媒体用動画像符号化方式の技術動向  [in Japanese] Technology Movement of Moving Picture Coding Method for Storage Medium  [in Japanese]

Abstract

放送通信と同様に蓄積媒体の動画像信号記録にも高能率符号化が用いられている.符号化方式としては,現在MPEG-2が最も広く使われており,符号化処理の改善が試みられている.より高能率を目指したMPEG-4では,最近Advanced Simple Profileが標準化され,現在Part 10 (H. 264)が検討されている.また米国を中心に独自規格も出ており,ネットワークのみならず蓄積媒体にも使われようとしている.これらの動向と技術内容については最新のPart 10 を中心に解説し,新しい符号化の研究動向も紹介する.一方,放送及び業務用機器ではフレーム編集の必要性からフレーム内符号化が一般的であり,その改良も試みられている.ストリーム記録においては変換符号化が行われる可能性が高くなってきている.

To video signal recording for storage medium, high efficiency coding is used same as broadcast and communication. Currently, MPEG-2 is most widely used coding method and enhancement of efficiency is tried. About the MPEG-4 which achieves more effective, most newly method is Advanced Simple Profile, and Part 10 (11.264) is discussed now. Some non-standard methods are used mainly in USA not only for network, but also for storage media. I show technical items mainly about newest Part 10 and movement of new coding method and study. On the other hand, professional equipment that requires frame editing uses intra-frame coding. Improvement is tried in this type coding. In case of bit-stream recording, using of tans-coding will be increase.
