Picture-in-picture

Picture-in-picture (PiP) is a multitasking feature commonly found in televisions, computers, and mobile devices. It allows a user to watch one video within a small window while simultaneously using other applications or watching another video in the main screen area. This feature is particularly useful for multimedia tasks, such as watching a video while browsing the internet or working on a document.

History

The concept of picture-in-picture was first introduced in the 1970s with the advent of advanced television technology. Early implementations were primarily found in high-end television sets, allowing viewers to watch two channels at once. Over time, the feature has been integrated into various digital devices, including smartphones, tablets, and computers.

Functionality

Picture-in-picture works by overlaying a smaller video window on top of the main screen. The smaller window can usually be moved around and resized according to the user's preference. The main screen continues to function normally, allowing the user to interact with other applications or content.

Television

In television, PiP is often used to watch two channels simultaneously. For example, a viewer might watch a sports game in the main window while keeping an eye on the news in the smaller window. Some advanced televisions also allow for multiple PiP windows.

Computers and Mobile Devices

On computers and mobile devices, PiP is commonly used for video conferencing, streaming services, and multimedia applications. For instance, a user might watch a YouTube video in a small window while working on a spreadsheet or browsing the internet.

Implementation

The implementation of PiP varies across different platforms and devices. On Android devices, PiP is supported natively from Android Oreo (version 8.0) onwards. iOS introduced PiP functionality with iOS 14. On desktop operating systems, PiP is often supported by specific applications or through browser extensions.
