Advanced Video Coding

Advanced Video Coding (AVC), also referred to as H.264 or MPEG-4 Part 10, is a video compression standard based on block-oriented, motion-compensated coding. Video compression picture types and Advanced Video Coding are video compression.

See Video compression picture types and Advanced Video Coding

Algorithm

In mathematics and computer science, an algorithm is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation.

See Video compression picture types and Algorithm

BMP file format

The BMP file format or bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device (such as a graphics adapter), especially on Microsoft Windows and OS/2 operating systems.

See Video compression picture types and BMP file format

Compression artifact

A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. Video compression picture types and compression artifact are data compression.

Data compression

In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Video compression picture types and data compression are video compression.

See Video compression picture types and Data compression

Digital television

Digital television (DTV) is the transmission of television signals using digital encoding, in contrast to the earlier analog television technology which used analog signals.

See Video compression picture types and Digital television

DVD

The DVD (common abbreviation for digital video disc or digital versatile disc) is a digital optical disc data storage format.

See Video compression picture types and DVD

Error detection and correction

In information theory and coding theory with applications in computer science and telecommunication, error detection and correction (EDAC) or error control are techniques that enable reliable delivery of digital data over unreliable communication channels.

Field (video)

In video, a field is one of the many still images displayed sequentially to create the impression of motion on the screen.

See Video compression picture types and Field (video)

Film frame

In filmmaking, video production, animation, and related fields, a frame is one of the many still images which compose the complete moving picture.

See Video compression picture types and Film frame

Global motion compensation

Global motion compensation (GMC) is a motion compensation technique used in video compression to reduce the bitrate required to encode video. Video compression picture types and Global motion compensation are video compression.

See Video compression picture types and Global motion compensation

Group of pictures

In video coding, a group of pictures, or GOP structure, specifies the order in which intra- and inter-frames are arranged. Video compression picture types and group of pictures are video compression.

See Video compression picture types and Group of pictures

Inter frame

An inter frame is a frame in a video compression stream which is expressed in terms of one or more neighboring frames.

See Video compression picture types and Inter frame

Interlaced video

Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth.

See Video compression picture types and Interlaced video

Intra-frame coding

Intra-frame coding is a data compression technique used within a video frame, enabling smaller file sizes and lower bitrates, with little or no loss in quality. Video compression picture types and Intra-frame coding are video compression.

See Video compression picture types and Intra-frame coding

JPEG

JPEG (short for Joint Photographic Experts Group) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography.

See Video compression picture types and JPEG

Key frame

In animation and filmmaking, a key frame (or keyframe) is a drawing or shot that defines the starting and ending points of a smooth transition.

See Video compression picture types and Key frame

Macroblock

The macroblock is a processing unit in image and video compression formats based on linear block transforms, typically the discrete cosine transform (DCT). Video compression picture types and macroblock are data compression and video compression.

See Video compression picture types and Macroblock

Motion estimation

In computer vision and image processing, motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another; usually from adjacent frames in a video sequence.

See Video compression picture types and Motion estimation

MPEG-2

MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". Video compression picture types and MPEG-2 are video compression.

See Video compression picture types and MPEG-2

Scan-Line Interleave

Scan-Line Interleave (SLI) is a multi-GPU method developed by 3dfx for linking two (or more) video cards or chips together to produce a single output.

See Video compression picture types and Scan-Line Interleave

Video

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. Video compression picture types and Video are data compression.

See Video compression picture types and Video

Videotelephony

Videotelephony (also known as videoconferencing or video call) is the use of audio and video for simultaneous two-way communication.
