CIF (Common Intermediate Format), also known as FCIF (Full Common
Intermediate Format), is a format used to standardize the horizontal and vertical
resolutions in pixels of YCbCr sequences in video signals, commonly used in video
teleconferencing systems. It was first proposed in the H.261 standard.
A feature in multi-point conferencing that allows the video endpoint to see images
from multiple video endpoints at the same time. All parties remain continuously
visible or 'present' for the duration of the call and the user can have control over the
screen layout. Continuous presence is better suited for team collaboration since it
allows participants to see the reactions (body language) of all participants, not just
the speaker.
During a conference, two channels of video streams can be sent or received
simultaneously. For example, one channel is used for transmitting video (such as
video captured by a camera) and the other channel is used for transmitting
presentation (such as a computer desktop). The two channels of videos can be
displayed on two displays.
