Glosarry of Terms

Avi- Audio Video Interleave (also Audio Video Interleaved), known by its acronym AVI, is a multimedia container format.AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback. Like the DVD video format, AVI files support multiple streaming audio and video, although these features are seldom used.

Mov-The format specifies a multimedia container file that contains one or more tracks, each of which stores a particular type of data: audio, video, effects, or text (e.g. for subtitles).

Streaming-Streaming is multimedia that is constantly received by and presented to an end-user while being delivered by a streaming provider. The name refers to the delivery method of the medium rather than to the medium itself. The distinction is usually applied to media that are distributed over telecommunications networks, as most other delivery systems are either inherently streaming (e.g., radio, television) or inherently non-streaming (e.g., books, video cassettes, audio CDs). The verb 'to stream' is also derived from this term, meaning to deliver media in this manner. Internet television is a commonly streamed medium.
Aspect Ratio-
Aspect Ratio-The term Aspect Ratio refers to the width of a picture (or screen) in relation to its height. Ratios are expressed in the form "width x height".
Frame Rates-
Frame rate, or frame frequency, is the frequency (rate) at which an imaging device produces unique consecutive images called frames. The term applies equally well to computer graphics, video cameras, film cameras, and motion capture systems. Frame rate is most often expressed in frames per second (FPS), (fps) and in progressive scan monitors as hertz (Hz).


File compression- File compression is the practice of packaging a file or files to use less disk space. The File Compression category includes software programs that will archive your files and extract archived files such as ZIP and RAR files. Many products in this category let you manage files and protect them with encryption. Notable titles include WinZip, WinRAR, and 7-Zip.
