Before the advent of on-screen displays, the only interface available for programming a home video recorder was a small VFD, LED or LCD panel and a small number of buttons. Correctly setting up a recording for a specific programme was therefore a somewhat complex operation for many people. G-Code, VideoPlus+ and ShowView were removed this ...
Video4Linux (V4L for short) is a collection of device drivers and an API for supporting realtime video capture on Linux systems. [1] It supports USB webcams, TV tuners, CSI cameras, and related devices, standardizing their output, so programmers can easily add video support to their applications.
The UVC driver has been included in the Linux kernel source code since kernel version 2.6.26. Detection of UVC 1.5 devices was introduced in Linux kernel version 4.5, [ 5 ] but support in the driver for UVC 1.5 specific features or specific UVC 1.5 devices was not added and MPEG-2 TS, H.264 and VP8 payloads are not supported yet.
In video production and filmmaking, SMPTE timecode is used extensively for synchronization, and for logging and identifying material in recorded media.During filmmaking or video production shoot, the camera assistant will typically log the start and end timecodes of shots, and the data generated will be sent on to the editorial department for use in referencing those shots.
A key component was a single camera-recorder unit, eliminating a cable between the camera and recorder and increasing the camera operator's freedom. The Betacam used the same cassette format (0.5 inches or 1.3 centimetres tape) as the Betamax, but with a different, incompatible recording format. It became standard equipment for broadcast news.

An example of a popular web API is the Astronomy Picture of the Day API operated by the American space agency NASA. It is a server-side API used to retrieve photographs of space or other images of interest to astronomers, and metadata about the images. According to the API documentation, [15] the API has one endpoint:
A short video explaining the concept of video codecs. A video codec is software or hardware that compresses and decompresses digital video.In the context of video compression, codec is a portmanteau of encoder and decoder, while a device that only compresses is typically called an encoder, and one that only decompresses is a decoder.
Digital video is an electronic representation of moving visual images in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images in the form of analog signals. Digital video comprises a series of digital images displayed in rapid succession, usually at 24, 25, 30, or 60 frames per second ...
