What are retrace lines on a tv?

Why TV Retrace Lines OccurI am no expert, but I will try to explain A standard TV screen is made up of 480 lines from top to bottom. Retrace lines will only happen on a TV with a regular Picture tube (known as a CRT), they will not happen on a LCD or Plasma screen. So before I say how retrace lines happen, lets first get little understanding of how the TV puts an image on a CRT. The lines on a CRT are made by a device in the back (known as the neck)of the picture tube called the electron gun. By use of magnetic fields controlled through a device called a Yoke mounted on the neck of the CRT. Now the electron beam emitted by the electron gun is made to go across the front of the CRT screen that is coated with a layer of Phosphor that glows when the electron hits it. When that beam starts at one side reaches the opposite side of the picture tube it has to quickly return back to that first side in order to make that next line. On a standard TV, in order to make the image of a single frame, it creates this line across the screen 240 times from top to bottom, it then returns to the top and starts down again with a second set of 240 lines that fill in between the first 240 lines to create one full frame image of 480 lines, and it does this 30 times a second. Now the retrace lines you are asking about happens when a circuit in the TV known as the Blanking Circuit, fails causing the Beam that is moving from the bottom to the top of the screen to become visible.


Who was in the television show with a Basset Hound I think the name of the show was Mr. Peoples?

I believe the show you are referring to was titled "The People's Choice" with Jackie Cooper as "Sock" and Patricia Breslin as "Mandy". The Basset Hound was a female red and white named Cleo (and had most of the good lines). The show ran from 1955 to 1958 (in B&W) but it was in reruns after that. Hope that helps.


What is SDTV?

SDTV stands for Standard Definition Television. It refers to TV that isn't HDTV (High-Definition Television). In the US, SDTV is 525 line with NTSC color encoding or 480 lines if the signal is digital. The figure of 480 refers to the number of active lines that make up the image. Note that the analog signal with 525 lines has blank lines at the beginning and end of each image, so the active area is still around 480 lines, plus or minus a few lines. In Europe, SDTV is 625 line with PAL color encoding, or 576 lines if the signal is digital. As with the US signal, the number 576 refers to the number of active lines making up the image. Whether or not the signal is digital, the resolution is identical. Digital signals will be component or RGB based and don't use NTSC or PAL encoding. Component signals however still carry the same information as PAL or NTSC signals. Component, whether digital or analog will normally provide significantly better image quality than either PAL or NTSC analog signals. In comparison, HDTV resolution uses 720 lines or 1080 lines for the image, so providing more detail.

Which 3D TV is certified flicker free?

Passive 3D televisions are claimed as flicker free. They do this by using alternate lines on the screen for the left and right eye. The effective resolution is therefore cut down to 540 lines instead of 1080 lines. Both active and passive types have their drawbacks and advantages. It is important to look at both before committing to buy a 3D television.


Is LG cinema 3d tv full HD?

LG PASSIVE 3d televisions deliver 540 lines to each eye both at the same time. Active televisions deliver 1080 lines to each eye alternately. Both use the full data rate of an HD signal but separate the two image channels in different ways. The better method is one of personal choice. Go and experience both and make you choice based on which looks better for you.

Can you recommend me a 3D TV that is a Full HD as well as comfortable 3D TV?

For full HD perception, active 3D televisions are the only choice. Passive televisions split the lines to two images so each eye sees only 540 lines. Compare that against the 576 lines for standard definition video. That rules out LG televisions which are one of the few that use passive technology. Take a look at Sony, Samsung, Panasonic and other big names but make sure you audition every model that you are thinking about buying.
