Picture-in-picture uses digital technology to display two sets of programs on the same screen. That is, one or more compressed sub-pictures are inserted at the same time as the main picture for normal viewing, so that other channels can be monitored while enjoying the main picture. Picture-in-picture is to place the sub-picture inside the main picture; similar technology also has picture-out-picture, which is to place the sub-picture outside the main picture. For example, 16: 9 color TV can set the picture-out painting. However, picture-in-picture and picture-out-picture in promotional advertisements are collectively referred to as picture-in-picture.

Picture-in-Picture in Analog TV

If the TV is equipped with two high frequency heads, namely the main high frequency head and the sub high frequency head, you can have picture-in-picture function. According to the circuit design in the movement, the picture of the sub-high-frequency head can be changed in various forms: for example, the small picture can be moved at the four corners of the screen, the sub-picture can be enlarged and reduced, and the main picture and the sub-picture can be on the screen. The left and right sides each take up half, becoming the so-called "dual window"; the main screen can also keep the current program unchanged, while the sub-screen can browse other channels. However, TVs with picture-in-picture functions may not all have picture-out-picture, dual-window and channel browsing functions. For example, Sony's picture-in-picture often comes with multi-channel browsing, Philips has picture-in-picture and dual-window functions, LG has picture-in-picture, picture-outside-picture, and dual-window functions. Picture, dual picture, channel browsing, strobe, still and switch functions. It should be noted that a TV with a channel browsing function does not necessarily have a dual tuner picture-in-picture function, because only one tuner can also perform channel browsing. This rear projection is used for multi-screen viewing. Because the only tuner is used, the program that is normally displayed will stop, and it will not be able to monitor another channel or dual channels at the same time with a small screen. Therefore, you must not mistake the channel browsing screen as a picture-in-picture.
