Will 120hz on a LCD TV affect a video signal from your TivoHD or does 120Hz just affect 24 frames per second sources?
A 120Hz television features a frame doubler. Normal television signals have 30 frames each second with each frame made of two fields so there are 60 fields each second. A 120Hz television is thought to eliminate some of the flicker from an image by generating intermediate fields between each of the broadcast fields. Whether or not it improves the image is a matter of opinion. Adding fields introduces small errors in the image and although more fields can be created, never can a frame doubler add information that wasn't in the original signal. The 120Hz feature refers directly to broadcast signals at 60Hz and not to 24 frame material. 24 frame material is derived from film and instead of being made up with two fields, the complete image is produced 24 times each second. A frame doubler will increase the rate to 48 frames per second if it takes the 24 frame material in it's native format. However, film is normally converted to a 60Hz signal using a technique known as 3:2 pulldown. This means that the first film frame will be sampled twice and will create two fields. The next film frame will be sampled 3 times and create three television fields. So, in 1/12 of a second, two film frames generate 5 television fields. If, at any time, the 24 Hz material is converted to 60Hz using 3:2 pulldown, the television will simply double the frame rate to 120 Hz. Indeed, the line doubler may use this technique anyway. The precise methods employed vary from one manufacturer to another so although it is safe to say that a 120Hz television will affect all incoming signals, the way they handle signals will vary. As a final note: European television runs at 50Hz, not 60Hz. Line doublers will convert to 100Hz. Also, 3:2 pulldown is not used in Europe. As the European frame rate is 25 FPS, film is run slightly faster than its normal 24FPS to comply with television standard frame rates. It means that films become 4% shorter on television than in a movie theater.
How many pictures come up every second on a black and white TV?
Standard Television systems run at 30 frames a second. That is really 60 1/2 frames interlaced. Same for color or black and white. New digital stuff uses all kinds of tricks to compress the signal.

What is the difference between 1080p and 1080i HDTV?
1080i and 1080p are both High Definition display formats for HDTVs. 1080i and 1080p signals actually contain the same information. Both 1080i and 1080p represent a 1920x1080 pixel resolution (1,920 pixels across the screen by 1,080 pixels down the screen). The difference between 1080i and 1080p is in the way the signal is sent from a source component or displayed on an HDTV screen. In 1080i each frame of video is sent or displayed in alternative fields. The fields in 1080i are composed of 540 rows of pixels or lines of pixels running from the top to the bottom of the screen, with the odd fields displayed first and the even fields displayed second. Together, both fields create a full frame, made up of all 1,080 pixel rows or lines, every 30th of a second. In 1080p, each frame of video is sent or displayed progressively. This means that both the odd and even fields (all 1,080 pixel rows or pixel lines) that make up the full frame are displayed together. This results in a smoother looking image, with less motion artifacts and jagged edges. 1080p can also be displayed (Depending on the video processing used) as a 1080p/60 (Most common), 1080p/30, or in 1080p/24 formats. 1080p/60 is essentially the same frame repeated twice every 30th of a second. (Enhanced video frame rate.) 1080p/30 is the same frame displayed once every 30th of a second. (Standard live or recorded video frame rate.) 1080p/24 is the same frame displayed every 24th of a second (Standard motion picture film frame rate.)

Why are tv's running at 1080p 24p?
Interlaced television signals run at 25 or 30 frames per second with 50 or 60 fields per second. (A field is half of the complete frame so two fields generate a full frame). Interlaced signals are designated with an "i". 1080i, 480i etc. Progressive signals normally run at 50 or 60 frames per second. Progressive signals are full frames without multiple fields. The designation is "p". 1080p, 720p etc. Films use 24 frames per second. As each frame of the film captures the whole image, it is progressive so 24p identifies a progressive signal at 24 frames each second. Whenever a film is broadcast, it is changed to suit the broadcast format. However, DVDs and computer generated or stored content can retain the film's frame rate. To display 24p content, a television must be capable of handling that format. The 1080 refers to the number of lines making up the image but this could be 480 or 576 lines if the image is standard definition rather than high definition. Although many televisions can handle 24p formats, not all of the do. Whenever a film is broadcast, it needs to be changed to a conventional format such as 1080i. There are two ways to do it. For European television, it needs to be converted to 25 frames per second. Generally, the film is run a few percent faster than the original speed and 24 frames per second becomes 25 frames per second. So, a 100 minute movie will be shown in 96 minutes. North American television runs at 30 frames per second and a technique known as 3-2 pull down is used. The first frame of the film is sampled and displayed over two television fields. The next film frame is sampled and displayed for three television fields. The process is repeated throughout the film transfer to video. The end result is that the film is converted to a television format and will last the same length of time as the original.
What is the best refresh rate for tv?
Frame rates vary depending on the video standard used. In North America and other areas that use NTSC as the standard definition color system, the standard frame rate is 29.97Hz. When the signal is interlaced (Standard definition, and 1080i in high definition) two fields are used to make a complete frame, so the field rate is 59.94Hz. High definition 720p is non interlaced, so the frame rate is 59.94Hz. In Europe, PAL is the color system and the frame rate is 25Hz, with a 50Hz field rate.
What does the p mean when speaking of a tv's resilution?
It means Progressive. As opposed to i, for interleaved. Progressive scan sets display their full resolution for every frame of video. Interleaved sets display TWO separate 'fields' for every frame- first they display the even numbered lines, then they display the odd numbered lines. ( much like normal NTSC TV broadcasts.) Because of persistence of vision, set with slower switching pixels will display a better picture with inteleaved video, as the eye will merge the two separate fields into one smooth frame. Progressive scan sets require a much faster switching speed because all of the pixels are switching together with each frame.
