Talk:Technology of television

Reorganising various analogue television pages
I've recently written how television works, intending it as a guide to what the various bits of electronics inside a television set do, and how they fit together. It has been suggested this should have been added to Technology of television instead. While we're at it, though, I think Analog television covers much of the same ground as Technology of television, and there's also overlap with Broadcast television systems and History of television. Many subjects are covered multiple times.

What do you think?
 * Is How Television Works redundant and can be deleted entirely?
 * Should we merge everything into one monster article?
 * Should we have smaller articles (e.g. display technology, analog switch-off, deployment by country) and a top-level index page?
 * Should we have parallel articles duplicating some content but with different focus?

 * Don't Merge - How television works is an indepth article that'll lose it's quality if merged. —IncidentFlux (talk) 09:32, 11 February 2008 (UTC)

Thanks. I propose a reorganisation as described below. IanHarvey (talk) 12:36, 20 February 2008 (UTC)


 * I agree with your proposal. Good suggestions. Thomprod (talk) 13:26, 20 February 2008 (UTC)

Proposed Changes
User:IanHarvey suggests the following:
 * Analog television
 * Analog television technology doesn't really distinguish CRTs (the display technology) from analog transmission technology, and should be moved to Technology of television, for instance.
 * Digital switchover section is good, and should become the main page for this information
 * should have more links to Broadcast television systems and How television works
 * Technology of television
 * The end of analog television broadcasting should be merged/linked back to Analog television
 * 'Transmission band' should be merged/linked to Broadcast television systems
 * Digital television
 * Analog switch-off should be merged back to Analog television and linked.
 * link to Broadcast television systems
 * How television works
 * Leave as-is for now - keep it focused on describing the insides of a TV set.

 * Keep in mind that the vast majority of television technology concepts are the same for both analog and digital television. And I think concepts are what people are looking for first when they look up an article like this one.  The concepts listed below might help in deciding which ideas are included in which articles.  Some of these concepts to find in existing literature are: Ohgddfp (talk) 23:05, 12 January 2015 (UTC)
 * TV is a series of still pictures Ohgddfp (talk) 23:05, 12 January 2015 (UTC)
 * TV picture resolution (picture definition) can be expressed in terms of pixels for digital television, and "equivilent pixels" for analog television. Ohgddfp (talk) 23:05, 12 January 2015 (UTC)
 * Picture elements (pixels) are transmitted one at a time, for both analog and digital television. Ohgddfp (talk) 23:05, 12 January 2015 (UTC)
 * A picture is rows and columns of pixels, where the pixels of analog TV are blended together left-to-right (without loss of picture information). Ohgddfp (talk) 23:05, 12 January 2015 (UTC)
 * At some point inside a digital TV receiver, the information is converted to analog for viewing. Ohgddfp (talk) 23:05, 12 January 2015 (UTC)
 * Some of today's digital TV stations use analog TV signals inside the studio, and convert the signal to digital for transmission. Ohgddfp (talk) 23:05, 12 January 2015 (UTC)
 * The color science utilized is the same for both analog and digital television. (They both use RGB as primary colors.) Ohgddfp (talk) 23:05, 12 January 2015 (UTC)
 * The digital television (MPEG-2) feature of using color-difference information at lower resolution is the same bandwidth-saving trick used by the analog (NTSC) broadcast system.
 * Both analog and digital TV transmission uses an amplitude modulation vestigial sideband system. This is mostly a single sideband amplitude modulation system which transmits the upper sideband frequencies, with the last vestige (a small part) of the lower sideband as well. Ohgddfp (talk) 23:05, 12 January 2015 (UTC)
 * Any 50-year old TV antenna that worked excellently for black and white analog TV on a given channel is also excellent for use with digital TV on that channel. Ohgddfp (talk) 23:05, 12 January 2015 (UTC)


 * Update 10/3/2008 - I've moved as many digital switchover articles as I could find to Digital switchover, with some more waffly stuff to Digital_switchover_in_the_United_Kingdom. It could do with some more work, but it's bedtime... IanHarvey (talk) 23:11, 10 March 2008 (UTC)


 * The page name should be changed if the article is kept. Analog television technology would be a likely name. -- Alan Liefting- ( talk ) - 06:34, 12 April 2008 (UTC)
