TV station 29-2 is not selectable on my HP IQ770

Kansas City TV stations transmit more than one program at a time, for example DTV 29-1, and DTV 29-2 are selectable on my TV but my HP IQ770 limits channel selection to DTV 29-1. How can I select the second program?

To solve the problem, Microsoft will have to update Windows VISA Media Player to scan for Digital TV Sub-channels. This may not happen now that Windows 7 is about to be released.

What does RF CH mean?


What is the difference between a RF channel and a virtual channel? The RF channel is the channel that the TV station uses to broadcast its signal. Before the conversion to digital, TV stations were normally identified by their channel number, and most people knew that a particular network was on a specific TV channel. While analog broadcasting was being phased out and all TV stations were converting to digital broadcasting, it was necessary for the TV stations to continue to broadcast their analog signals on their original RF channels, and also broadcast their digital signals on a different RF channel. However, since the TV station used their broadcast channel as part of their identification, they wanted to keep using the same channel number. To allow this to happen, the new digital television broadcasting standards (ATSC) provided TV stations the ability to continue to use their original channel number and also tell the TV set to tune to the new RF broadcast channel when their virtual channel number was selected. The original channel number is called the virtual channel number, and it will be followed by a period and a second number (3.1, 7.1, etc.).
One of the benefits of converting to digital for the TV stations is that they now have the ability to transmit more than one program at the same time on the same RF channel. The number of additional channels they can broadcast is determined by the resolution of the program (SD vs. HD, text only, music only, etc.). The second number in their virtual channel number indicates that one of the additional programming sources from the same TV station is being viewed (10.2, 10.3, 10.4, etc.).
When selecting an antenna, it is important to understand the difference between the RF broadcast channel and the virtual channel. Antennas are designed to receive specific ranges of RF channels, and the antenna needs to be selected for the RF channel you wish to receive. TV stations broadcast in two broad frequency ranges, called VHF and UHF. RF channels 2 through 13 are considered VHF, and RF channels 14 through 51 are considered UHF. In order to pick up the channels, the antenna has to be designed for the correct frequency range. It is very common today to find that TV stations using virtual channels 2 through 13 are actually using RF broadcast channels in the UHF range. Although not as common, some TV stations using virtual channels 14 through 51 are actually transmitting in the VHF range. An antenna designed for only UHF channels will not work effectively for RF broadcast channels in the VHF range, and an antenna designed for only VHF channels will not work effectively for RF broadcast channels in the UHF range.

What specific model of JVC multi-system TV do you have? What is the signal source?

The majority of the JVC multi-system TVs that I've researched only have analog tuners (NTSC, PAL). The AV-29LX is an example of the older JVC TVs. Since most over-the-air signals are digital, you will need a digital-to-analog OTA signal converter to watch any signal from an aerial TV. If you have a cable system that has upgraded to digital cable, you will need a cable box.

Converter boxes are harder to find but there are a few remaining. Here's one for the US: http://www.amazon.com/Magnavox-DTV-Digital-Analog-Converter/dp/B0013ZKZGU .

I wish that I had better news for you.

(A few low-power stations still broadcast in the analog format. However, you have to be really close to the station or have an outdoor antenna to have a chance at receiving the signal.)

How do I know which direction to point my TV antenna?


Well TV transmitter stations are usually located on top of high hills or really tall buildings. So you want to point your antenna towards something tall. If you live in a largely flat area just face it straight up.

CBS station is gone. Only shows instructions for converter box.


I live outside the Kansas City Missouri area. I was having problems receiving one station. I decided to raise my outside attenna to get better reception. In doing so, I totally lost reception on another station. I only moved it up about 6'. I had to move the attenna back down to get that station perfect again. I still cann't get the station I'm missing but I found out that moving the attenna up/down or side to side can make a huge difference. I live about 50 miles from the stations I receive. Good Luck.

Since Texas went digital I am only getting some of the digital chanels. I have changed it to digital programming but they are not all coming through. What do I need to do?


we need more information:

1) Your city in Texas; so I can look up the stations and find what frequency's they are broadcasting their DTV on.

2) What kind of antenna do you have ?
VHF ? UHF ? Inside ? On the Roof ?

A couple things you can try:

- instead of having the TV AutoScan for channels, manually enter the channel for the TV stations not being received.

- call the TV station you're having trouble receiving: they will ask you where live, what kind of antenna you have etc..


but you really should have a 'roof mounted' antenna that is matched to youre reception needs.

My 32" Toshiba LCD HDTV keeps freezing on the same channel and when I try to change the channel or input selection, it doesn't respond(to the remote or directly on the TV.) The only thing that works is...


These problems are normally caused by the TV station.

1. Call the TV station responsible and ask for the network engineer.
2. Tell him the Day, Time, Channel, Program, basically every little detail about the problem.
3. The station will normally check it and fix it.

Also, contact Toshiba and tell them. Really this is part of the DTV Transition thing. Many stations are reconfiguring and settin up equipment. They sometimes make mistakes. Don't worry much about it unless it continues for more than a week. If you like the station, I would call right away.

My LCD won't tune into DTV


You need to go to your menu option with your remote. Select channel scan from the options listed in setup. This will allow the turner to find your DTV channels again. Hope this helps. J

Switch to DTV -- how can I watch one program and record another


Unless the box has two digital tuners in it then I believe what you are trying to do is impossible. Find out first if it does have two digital tuners.

Intermittent reception with DTV converter box


Hello,

I install at least 2-3 antennas a week. While Analog stations were no big deal when it came to reception, Digital signals are very directional, and can be very fickle about reception sometimes. Digital is "all or nothing," meaning that if you get enough signal to get a picture, then great, but if you don't, it won't allow you to even try to make the picture.

My suggestion is to first try a 15-25 dB amplifier (with an FM trap) on the antenna. Use it first in-line, immediately following the antenna, before it is fed to any TV's. If that doesn't help, try re-aiming the antenna directly toward the city from which your signals are being broadcast. You'd be suprised how little you have to turn it to make a big difference.

Give these two things a shot. Hope this helps you...
