b-frame is a framework for rapid J2EE development. It is based on the assumption that it is possible to create business applications just from knowing their structure. It defines sets of XML tags for describing databases and applications operating on these databases and template implementations , respectively.
Bidirection predictive frame. A video compression method used in MPEG encoding which creates an in-between frame by calculating only the differences from the frame before and the frame after it.
In inter-frame compression schemes (e.g., MPEG), a highly compressed, bidirectional frame that records the change that occurred between the i-frame before and after it. B frames enable MPEG-compressed video to be played in reverse. Contrast with i frame and p frame.
a Bi-directional predicted frame that looks for a changing path between both the picture that precedes it and the one that follows it
an incrementally encoded video frame that can be decoded with the information in the preceding and following anchor frames (I-frame or P-frame)
a picture that is b idirectionally predicted - My take on this is that it's a picture that is based on both the previous and following picture
Bi-directional frame - MPEG difference frame which is based on both the previous and next frame. Similar to a QuickTime delta frame, only with the ability to see what's ahead.
An MPEG difference frame that is based on both the previous and next frame. It is similar to a Quicktime Delta frame, but with the ability to see what is ahead.
Bi-directional frames use both a past and subsequent frames as a reference to calculate compressed frame data.
Bidirectionally predictive-coded frame. In MPEG video, a B-frame is encoded using data describing how its picture has changed from the picture in the closest two I-frames or P-frames, one in the past and one in the future.
Bi-directional frame. The frame in an MPEG sequence created by comparing the difference between the current frame and the frames before and after it.
Also referred to as B-Picture. Bi-directional predictive-coded picture. A picture that is coded using motion compensated prediction from past pictures (I-pictures) and/or future reference pictures (P-pictures). In this process background and/or other information is stored for re-use in future frames so that the transfer speed of a digital video stream is increased because it does not have to repeatedly send redundant information.
