KTRE-DT is proud to air selected programs in HDTV. Many viewers have called and e-mailed us, trying to wade through the sometimes confusing terminology of digital television. In this article, I will explain to you what equipment you should have and what you should do to receive KTRE-DT.
First, let me begin by saying that not all TV sets are created equal. You may have to pull your manuals out for your TV to review.
Q: My TV says it is a HDTV monitor. Can I pick up KTRE-DT on my set?
A: In order to receive KTRE-DT, your TV must have an ATSC (HDTV) tuner. HDTV monitors do not have a built in HDTV tuner. You can purchase a “set top box” ATSC tuner separately that will get the job done.
Q: What’s the difference between between EDTV (Enhanced Definition Television) and HDTV (High Definition Television)?
A: EDTV and HDTV use a progressive scan. Unlike analog sets, which scan the odd lines on a TV screen then fly back and scan the even lines to complete the picture, progressive scan TVs light all the horizontal lines in the same instant. This makes a much sharper picture. EDTVs only scan 480 lines (referred to as horizontal resolution), but in order to make a true HDTV picture, the scan must be at least 720p or greater. (The “p” stands for “progressive”. You may also see references to 480i or 1080i, in which the “i” stands for “interlaced”; this refers to the odd/even scanning mentioned earlier.) ABC’s High Definition programming is in the 720p 16:9 format (widescreen).
Q: Okay, enough of the Q & As. I have an ATSC tuner, but I still can’t see KTRE-DT. What do I need to do?
A: In order to receive KTRE-DT by terrestrial airways, you must have an antenna hooked to your tuner. Depending on how far away from the station you are determines what type of antenna is required. You may be able to receive KTRE-DT on “rabbit ears” or amplified rabbit ears if you live inside our City Grade signal. You may need an outside VHF antenna if you live further away, or an antenna with a preamp. Make sure it is pointed in the direction of KTRE-DT’s transmitting tower in Pollok, TX, located about seven miles north of Lufkin on Highway 69.
The next step is to find our digital signal. Every make of TV is different, so I will have to speak in generalities here. Go to your TV’s menu and select “Channel Search”. Make sure you have your input source on antenna. Have your TV do a channel search that includes digital channels. Some sets are automatic and search for both analog and digital signals without further prompts from you. If the search is successful, you should be able to see that your TV found three digital signals. The three digital signals are all KTRE-DT: 9.1 (9 dot 1), 9.2 and 9.3.
On 9.1, you will find KTRE’s up-converted (analog to digital conversion) and ABC’s HDTV programming. It is normal during up-converting to see black bars on the sides of the picture. When ABC’s true HDTV is broadcast, it will fill your screen with a 16:9 aspect ratio picture. Even though you are watching high definition programming, many commercials are not produced in this format.
On 9.2, we have given our viewers a real treat, a tool you will use and wonder how you got along without it. It’s our 24/7 Weather channel. Twenty-four hours a day, you will be able to tune in and see live radar images, current conditions in many of our viewing communities, and weather forecasts. Our 24/7 Weather channel gives you all this and more!
I hope this has helped, but if you have further questions, you can call the KTRE studios at 936-853-5873 between the hours of 8 a.m. and 5 p.m. Monday through Friday.
