The MPEG compressed video frame where redundancy between adjacent frames is not taken into account, only the information I a single frame is compressed. It is used in conjunction with the B (bi-directional) and P (predictive) frame encoding. If frames are lost during MPEG decoding, the decoder cannot fully recover until the next I frame comes along. The frequency of I-frames in a sequence determines how long it takes to get a reasonable picture after a random access or loss of data.
A.k.a. intra pictures, I-frame is typically the first frame of each GOP (apart of video compression technology used by MPEG), is moderately compressed, and serves as the reference points for random access and can be likened to images.
In inter-frame compression schemes (e.g., MPEG), the key frame or reference video frame that acts as a point of comparison to p- and b-frames, and is not rebuilt from another frame. Opposite B frame and P frame.
a bit like a JPEG image, since only intraframe compression occurs
a compressed version of all of the information in one frame of a video stream
a frame that transports data over an access link
a full video frame containing the same information that a MotionJPEG frame would contain
a standalone frame that can be used within a html page and doesnt need a frameset
A complete MPEG frame containing the entire image. This is the same as key frames in Quicktime/AVI.
These frames, that generally occur twice during every 30 frames of digital information, depending on the completion of the picture, work to reduce data by providing a full frame reference of the video image. The I-frames identify the entire background and are the initial reference frames for bi-directional and P-frames.
Intra-coded frames. In MPEG video, an I-frame is a frame coded as a still image, not using any past history.
Information frame. One of three SDLC frame formats. See also S-frame and U-frame.
A frame that is not reconstructed from another frame. An I-frame is also a reference frame; it serves as a reference to construct other frames.
