Line 97: \|- \| 48,000 Hz \| The standard audio sampling rate used by professional digital video equipment such as tape recorders, video servers, vision mixers and so on. This rate was chosen because it could reconstruct frequencies up to 22 kHz and work with 29.97 frames per second NTSC video – as well as 25 frame/s, 30 frame/s and 24 frame/s systems. With 29.97 frame/s systems it is necessary to handle 1601.6 audio samples per frame delivering an integer number of audio samples only every fifth video frame.<ref name=AES5/>  Also used for sound with consumer video formats like DV, [[digital TV]], [[DVD]], and films. The professional ~~Serial Digital Interface~~ [[~~Serial~~serial ~~Digital~~digital interface]] ~~Interface\|~~(SDI)]] and High-definition Serial Digital Interface ~~[[Serial Digital Interface\|~~(HD-SDI)]] used to connect broadcast television equipment together uses this audio sampling frequency. Most professional audio gear uses 48 kHz sampling, including [[mixing console]]s, and [[digital recording]] devices. \|- \| 50,000 Hz
