Annotation of standard text IEC 62141-ed.1.0 :
IEC 62141:2005 specifies the track content, format, and recording method of the data blocks containing compressed video, AES3 audio data, and associated data which form the helical records on 12,65 mm tape in cassettes. This standard supports recording of source picture formats using 1920 x 1080 pixels with the 4:4:4 and 4:2:2 sampling structure specified in SMPTE 274M at the frame rate of 23,98 Hz, 24 Hz, 25 Hz and 29,97 Hz, and using 1280 x 720 pixels with the 4:2:2 sampling structure specified in SMPTE 296M at the frame rates of 50 Hz and 59,94 Hz (see note). This standard also supports recording of 12 channels of AES3 audio data and 3 lines of uncompressed blanking interval data. This standard includes packetizing and shuffling operations supporting picture compression using the DCT and DPCM encoding methods defined by ISO/IEC 14496-2 (MPEG-4 simple studio profile). This bilingual version (2012-11) corresponds to the monolingual English version, published in 2005-10. La CEI 62141:2005 definit le contenu des pistes, leur format et la methode denregistrement des blocs de donnees contenant de la video compressee, des donnees audio AES3 et des donnees associees qui forment les enregistrements helicoidaux sur une bande de 12,65 mm dans des cassettes. La presente norme prend en charge lenregistrement de formats dimage source utilisant 1920 x 1080 pixels avec la structure dechantillonnage 4:4:4 et 4:2:2 specifiee dans la SMPTE 274M aux frequences image de 23,98 Hz, 24 Hz, 25 Hz et 29,97 Hz, et utilisant 1280 x 720 pixels avec la structure dechantillonnage 4:2:2 specifiee dans la SMPTE 296M aux frequences image de 50 Hz et 59,94 Hz (voir note). Cette norme prend egalement en charge lenregistrement de 12 voies de donnees audio AES3 et 3 lignes de donnees non compressees dintervalle de suppression vertical. Cette norme inclut les operations de mise en paquets et de brassage prenant en charge la compression dimage utilisant les methodes de codage DCT et DPCM definies par lISO/CEI 14496-2 ("MPEG-4 simple studio profile"). La presente version bilingue (2012-11) correspond a la version anglaise monolingue publiee en 2005-10.
