Programmer TV

[curieuxdino]

Je possède depuis un certain temps un téléviseur LCD de Marque RCA (40") modèle RCL 1033; avec le câble ça va nickel mais comme je ne regarde la télé que très (et c'est peu dire) rarement, je me suis acheté un truc permettant de capter certaines chaînes en HD sans les services du cable. Sur un petit téléviseur de 30" ça roule super bien mais dès que j'essaie sur le gros téléviseur, je suis incapable de trouver l'option "antenne" (car le bidule se branche comme une antenne mais dans l'entrée coaxiale du câble.

 

J'ai comme options : CATV HRC AIR IRC ?

 

Des suggestions ?          M e r c i

      --------------------------------------------------

 

The abbreviation CATV is often used for cable television. It originally stood for Community Access Television or Community Antenna Television, from cable

(ton entree standard cable)

STD, HRC, and IRC are cable television formats.

STD HRC and IRC Reference

While the terms HRC and IRC are slowly phasing out, many TVs still allow the option of setting up your tuner to one of these 3 formats.

STD	Standard     (dans ton cas  CATV)
HIC	Harmonically Related Carriers
IRC	Incrementally Related Carriers

Additionally you might have the option to select analog vs digital. You want digital if available, but it likely won’t matter as analog cable is going the way of the dinosaur and if you have a “digital cable box,” all your programming is coming into the house digitally already (and then converted to analog by the box).

Au final:

If you have cable TV and live in a major city, or if you have satellite television like DISH Network or DirecTV, then you want to always select STD standard.

If you live in a rural community that is running an older cable system, then you might benefit from trying HRC or IRC.

What’s the Difference

Older cable trunk lines suffer from signal degradation over and distance and require amplifiers to maintain signal strength. This amplification introduces noise into the cable signal. HRC and IRC are formats that the cable companies use in an attempt to clean up signals and improve audio/video quality. They slightly alter the frequency in order to make interference less noticeable, but most people would be hard pressed to tell the difference.

 

 Today, most cable systems use STD.

 

Which do I Choose?

This is an official position from Brighthouse Networks and also our Solid Recommendation:

Always select STD (standard) if your TV offers this setting. Choosing the others could result in reception problems or missing channels.

If you have cable TV and live in a major city, or if you have satellite television like DISH Network or DirecTV, then you want to always select STD standard.

If you live in a rural community that is running an older cable system, then you might benefit from trying HRC or IRC. Results will vary as it is not an exact science, but you should take notes of the number of channels found and your opinion of quality between each. After comparing, choose which one you like.

For you worry warts- your TV set does not care which format you choose and it cannot hurt anything.

Irc

 

Incrementally-related carriers (IRC)

Incrementally-related carriers (IRC) is a system for assigning television channel numbers to bands of frequencies over a cable TV network.^[11] The IRC plan attempts to minimize distortion products by deriving all video carrier signals from a common source.^[12] The IRC system assigns channel frequencies (for the North American NTSC-M system) spaced 6 MHz apart. In an IRC system, the VHF channels are at their off-air frequencies except for channels 5 and 6, which will be 2 MHz higher than usual.^[13]
