What is Picture-In-Picture?
Picture-in-picture (PIP) is a feature that some televisions have that allows you to watch two programs at once by placing a small, inset window inside the main window. The inset window has no sound, but allows you to keep track of what’s playing on the second channel. Pressing a button on the remote will switch windows, placing the secondary channel into the main window, and visa-versa. Picture-in-picture can come in quite handy. For those who can’t sit through commercials and find themselves flipping to another program to watch in the interim, putting the original show in the inset window will eliminate having to guess when commercials are over. PIP is also useful while waiting for a particular item on the evening newscast. A teaser might be announced repeatedly while segment after segment continues. By using picture-in-picture you can place the newscast in the secondary window and watch another program until the news item appears. For breaking news, picture-in-picture will let you ke
Picture-in-picture (PIP) was common with better models of analog TVs back when that’s all there was. Such sets had two NTSC (analog) tuners which made it possible to watch a primary channel while getting a thumbnail (small picture) view of a second channel at the same time. You could then flip to the secondary channel with your remote if you wanted to watch that channel instead. This arrangement worked best with over-the-air (OTA) antennas or direct cable connections without a set-top-box (STB). Not quite so do-able with satellite receivers or a cable STB. Modern TVs all come with at least two tuners and maybe three (analog, digital, and maybe an optional QAM tuner for limited free digital channels on cable). Since they’re now packing 2 or 3 tuners in each set, they’ve pretty much stopped including a second identical tuner (analog or digital), which means no more PIP. Some sets do have this feature, but it requires some intricate connection of two signal sources, like an OTA antenna pl
Picture-in-Picture is a feature where single programme is displayed on the TV screen in full screen mode while one or more programmes are displayed in the inset windows. And audio is mainly from the main program. This is made possible with the two independent tuners carrying signals for both full screen and the inset screen. Televisions that are built with two tuner PiP usually have built in second tuner apart from the first. Whereas, a single tuner TV would require an external signal source, which is the external tuner. PiP feature can be used to watch programmes on the main screen while you wait for the advertisements and other programmes to get over in the inset screen. History The first type of PiP was seen during the Montreal Olympics held in 1976 where a close up picture of the Olympic flame was shown in an inset screen using a qualtel digital framestore device during the opening ceremony. NEC in 1980 introduced Popvision television with 6 inches CRT and a tuner. Later, advanced
