Starting from the beginning of TV in the last part of the 1920’s the shopper has chosen the channel to see by choosing a number on the television, for example, stations 2 to 13 for VHF and 14 to 69 for UHF. With the approach of digital television this has changed to some degree with station choices from 2 to around 99. The typical customer has become entirely OK with this framework.
At the point when the business started improvement of computerized television and pressure they needed to foster another framework. The standard that was created was laid out by the High level TV Norms Council (ATSC).
Since computerized packed television is presently fit for communicating more than one program on a Station it was chosen to give the program a Significant station number and a Minor station number isolated by a period (.).
For example a computerized program that is carried on VHF channel 6 would be https://testecs48horas.vip/ called 6.1. On the off chance that a second or third program was being sent they would be called 6.2 or 6.3. In the event that they were communicated on an UHF channel they would be 45.1, 45.3 and 45.7. To make things much really befuddling the FCC ordered that Television slots being communicated on Stations 2-6 move to another recurrence. This frequently brought about a channel that was referred to for a considerable length of time as Channel 3 to be communicated on UHF channel 26 however called 3.1… Extremely confounding to be sure.
At the point when these projects were gotten by the nearby link organization it would in general get significantly more confounding until the Virtual channel numbering framework was presented. This is on the grounds that on a link framework, there can have upwards of 10 or 12 projects carried on one channel and the channel might be unimportant to the program number or customary channel number.
With the presentation of a virtual channel number framework a number is relegated to a Program paying little heed to where the channel is really carried on the framework. This implies the number showed on the television or Link box will be somewhere in the range of 2 and 999 and won’t have any copies and no minor numbers, for example, a.1 or.2. The framework administrator can appoint any virtual number.
For example, when we take a gander at channel 3 referenced above it is communicated by the telecaster on UHF station 26. The link organization might put it on the link on channel 57.3 yet they have set it on virtual channel number 3. This way when you select station 3 on your link box, the old channel 3 you looked for a really long time is what you get.
