NICAM and NICAM 728

edit

NICAM (known also as NICAM 728, after the 728 kbit/s bitstream it is sent over), Near Instantaneous Companded Audio Multiplex, is a format for digital sound on analogue television transmissions. Audio is encoded using 14 bit pulse-code modulation at a sampling rate of 32 kHz. It has been standardized as ETS EN 300 163[1].

I think that needs a rewrite. --jmb 00:50, 19 January 2007 (UTC)Reply

  • There is NICAM which is a coding system and was (I think) developed by the BBC for the distribution of stereo sound radio services around the country, replacing the previous PCM system used for Mono radio services.
  • And there is NICAM 728 which is the system used for TV sound.
  • The article is written as if NICAM only means TV stereo sound.

I must tell NICAM728 is about 728lines the video signal that audio signal is multiplexed with. NICAM isnot digital service but analodghical one.188.25.52.57 (talk) 05:22, 9 July 2011 (UTC)Reply

VHS Hi-Fi Stereo

edit

The article states "The Hi-Fi tracks are written diagonally between the digaonal video tracks". This is incorrect. The Hi-Fi audio tracks are actually recorded beneath the video tracks, using a process known as "depth multiplexing". See http://en.wikipedia.org/wiki/Vhs#Audio_recording. 86.149.199.3 (talk) 20:22, 29 October 2009 (UTC)Reply

Usage in Denmark

edit

Nicam is still being used in cable systems in Denmark that still have Analog signal. This is YouSee and Stofa.
