What does STD HRC and IRC mean on a TV?
Older televisions require the users to select between channels to eliminate any interference in these signals. Two of the most commonly used signal types are HRC (Harmonically Related Carriers) and IRC (Incrementally Related Carriers).

What is digital cable system?
Digital cable is the distribution of cable television using digital data and video compression. In addition to providing higher resolution HD video, digital cable systems provide more services such as pay-per-view programming, cable internet access and cable telephone services.

What is cable STD HRC IRC?
Harmonic Related Carrier (HRC) – Harmonic Related Carrier is a method of spacing and transmitting television channels on a cable television system to prevent interference. The channels are spaced at 6-MHz intervals, with all carrier frequencies harmonically related to a common reference.
Why is my TV not picking up any channels?
First check that your TV is set to the correct Source or Input, try changing the Source or Input to AV, TV, Digital TV or DTV if you haven’t already. If your “No Signal” message is not due to incorrect Source or Input being selected, then it’s most likely caused by a set up or antenna fault.
Is antenna air or cable?
Antennas receive over-the-air (OTA) signals, and may be perfect if you’re strapped for cash or just want a few channels. Cable television can be the way to go if you’re looking for plenty of diverse programming.

Compression Kills Cable Quality The obvious difference between cable and OTA TV is channel-density. Cable TV is comprised of a few thousand channels, while OTA TV only broadcasts (at max) 69 channels for each locality. This difference in channel-density is the big reason why cable doesn’t look as good as OTA TV.
What input should my TV be on?
If you’re using a coaxial cable, your television’s on-screen input list will usually label it as either TV or ANTENNA. On the back of the television it will usually be labeled ANTENNA or a variant of it, such as ANT. Most televisions will also need to be on either channel 3 or 4 when using a coaxial connection.
What does HRC stand for in cable TV?
If your first broadcast channel is channel 1, then your cable company uses the HRC (Harmonic Relate Carrier) method. Note: When you begin the process of programming channels into some TVs, you have to select which video transmission format your cable company uses before you can start the programming process.
Are there different channel spacing for HRC and IRC?
First, most cable companies are probably using standard channel spacing. HRC and IRC/ICC use a slightly different spacing to eliminate some potential interference problem I can’t remember, and as a side-effect get an extra channel in between channels 4 and 5.
What does STD stand for in cable TV?
But STD is short for standard, meaning that cable channels 14 – 22 fill in the large space above the FM band between channels 6 and 7, then just march up the band above channel 13.
