NICAM and NICAM 728

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)

• 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 agree. I've started the rewrite. Harumphy 17:13, 2 April 2007 (UTC)
    • Thanks, I get fed up of trying to convince people that NICAM is a bit more than stereo TV! --jmb 20:06, 2 April 2007 (UTC)

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)

• 728 refers to the bit-rate of the Nicam carrier. The article already says this. --Harumphy (talk) 07:05, 10 July 2011 (UTC)

VHS Hi-Fi Stereo

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".

NICAM vs MTS

Someone should add a refference to link article to the similar "MTS service" in north america. Cheers188.25.107.166 (talk) 06:56, 10 July 2011 (UTC)

• There's already a link under 'see also'. --Harumphy (talk) 07:05, 10 July 2011 (UTC)

Usage in Denmark

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