Picture-in-picture

Source: Wikipedia, the free encyclopedia.

Picture-in-picture (PiP) is a feature that can be found in television receivers, personal computers and smartphones, consisting of a video stream playing within an inset window, freeing the rest of the screen for other tasks.

For televisions, picture-in-picture requires two independent

advertisements
to finish.

History

Adding a picture into an existing picture was done long before affordable PiP was available on consumer products. The first PiP was seen on the televised coverage of the

MSRP, equal to about $1,200 (at $1 = ¥250 [2]), and $1,200 in 1980 had the approximate buying power of $3,000 in 2007 [3]
.

An early consumer implementation of picture-in-picture was the Multivision set-top box; it was not a commercial success. Later, PiP became available as a feature of advanced television receivers.

The first widespread consumer implementation of picture-in-picture was produced by

black and white
in one of the four corners of the screen. Televisions at the time were still analog format, and earlier versions of the PiP implemented in analog were too costly. New digital technology allowed the second video signal to be digitized and saved in a digital memory chip, then replayed in a mini version. While the new technology was not good enough for color or full-screen viewing, it did provide a low-cost PiP feature.

The

Blu-ray Disc and HD DVD specifications included picture in picture, allowing viewers to see content such as the director's commentary on a film they are watching. All the Blu-ray Disc titles in 2006 and 2007 that had a PiP track used two separate HD encodings, with one of the HD encodings including a hard-coded PiP track. Starting in 2008 Blu-ray Disc titles started being released that use one HD and one SD video track which can be combined with a Bonus View or BD-Live player. This method uses less disc space, allowing for PiP to be more easily added to a title. Several studios have released Bonus View PiP Blu-ray Disc titles in 2008 such as Aliens vs. Predator: Requiem, Resident Evil: Extinction, V for Vendetta, and War.[1][2][3][4]

Some

Android 8.0)[7] and iOS (as of iOS 14)[8]
similarly provide native APIs for picture-in-picture overlays.

In 2011, after DirecTV released the HR34 Home Media Center HD DVR, Picture in Picture was introduced to all HD DVR models onwards, The feature has five options: Upper Left, Upper Right, Lower Right, Lower Left, and Side-by-Side.[9][10]
