Since the begin of Television in the late 1920’s the consumer has picked the channel to look at by selecting a quantity on the Tv set this sort of as channels two to thirteen for VHF and 14 to sixty nine for UHF. With the introduction of cable Tv set this has changed relatively with channel alternatives from two to about 99. The common buyer has become really comfortable with this technique.
When the market started advancement of digital Tv set and compression they had to create a new program. The common that was developed was proven by the Superior Television Specifications Committee (ATSC).
Because Pinoy Tambayan compressed Television is now capable of transmitting far more than a single system on a Television channel it was determined to give the software a Significant channel amount and a Minimal channel number separated by a period of time (.).
For occasion a digital plan that is carried on VHF channel six would be called six.one. If there was a 2nd or third plan currently being transmitted they would be referred to as 6.two or six.three. If they were transmitted on a UHF channel they would be 45.one, forty five.3 and 45.7. To make issues even much more puzzling the FCC mandated that Television stations becoming transmitted on Channels two-six go to another frequency. This usually resulted in a channel that was known for fifty many years as Channel three to be transmitted on UHF channel 26 but known as 3.1… Extremely confusing without a doubt.
When these packages were picked up by the local cable firm it tended to get even more puzzling until the Digital channel numbering system was introduced. This is because on a cable system, there can have as many as 10 or twelve plans carried on a single channel and the channel may possibly be irrelevant to the plan variety or traditional channel quantity.
With the introduction of a digital channel number program a number is assigned to a Plan irrespective of in which the channel is truly carried on the program. This indicates the amount exhibited on the Tv set or Cable box will be among 2 and 999 and will not have any duplicates and no minor numbers these kinds of as a.one or.two. The method operator can assign any virtual quantity.
For occasion, when we seem at channel 3 mentioned above it is transmitted by the broadcaster on UHF channel 26. The cable organization may spot it on the cable on channel 57.three but they have established it on virtual channel quantity three. This way when you choose channel three on your cable box, the outdated channel three you watched for several years is what you get.
