Talk:Video recorder scheduling code

Merge proposal
Yeah, support. They're both describing the same thing. Fourohfour 20:30, 17 August 2006 (UTC)

Request to update the article
With the obsolescence of the VCR and the transition to DTV in America, is VCR Plus still supported by any device?--Kencaesi (talk) 18:44, 28 October 2009 (UTC)
 * Not sure what your point is, neither is relevant surely. DVD and Hard Disc recorders have mostly taken over from video recorders these days... my digital recorder supports Videoplus, and I currently use the numbers to programme it to record things from digital t/v. 91.85.162.72 (talk) 19:41, 6 December 2011 (UTC)

VideoPlus
not sure - but I think so - most of the TV listings still include the codes Robthehornet (talk) 20:39, 14 April 2010 (UTC)

Differences Between Systems
I used to work for Gemstar in the mid-90s as a field support engineer and can clarify the technical workings of a lot of this.

The 7 and 8 codes were generated using 'table files' which were sent to publications every month. Without these table files it was impossible to predict the encoding mechanism for the 7 and 8 digit codes. The 9-digit codes prefixed the 8-digit codes with a numeric offset (up to 8 digit codes were accurate only to 5-minute intervals, 9-digit added on the minute offset 1-4).

There were different algorithms - subtly different - for VCR Plus, ShowView and VideoPlus.

ShowView was European (ish - we did an install in Russia at one point), VideoPlus was pretty much exclusively UK, and VCR Plus was the rest of the world.

I'll leave it to another editor to amend the article if deemed necessary. Capnb (talk) 15:39, 8 December 2011 (UTC)

Barcode programmer?
I seem to recall a short-lived variation of this idea, that might have predated it, using a barcode scanner comparable to a CueCat (a failed technology used for scanning codes from printed material, that would translate to URLs in a web browser). If anybody remembers what it was called, or why it failed, I think it would be worth adding to the article. B7T (talk) 02:39, 9 November 2016 (UTC)
 * Some nominal research via Google indicates that Panasonic had a barcode-based VCR programming technology, but I'm not sure whether it was able to understand barcodes that might have been in a printed TV schedule, or only from the card that came with the device, which seems to have had sets of codes for days of the week, times in half-hour increments, and channel numbers (see this, for example, which includes a print and television ad). If the latter, it seems more of a marketing gimmick than an actual improvement; as far as I can tell, substituting scanning for button-pushing.  But maybe it's still worth mentioning in this article?
