1. In data transmission, the sequence of contiguous bits delimited by, and including, beginning and ending flag sequences.
Note 1: A frame usually consists of a specified number of bits between flag sequences and usually includes an address field, a control field, and a frame check sequence.
Note 2: Frames usually consist of a representation of the original data to… (Read More →)

1. In the reception of framed digital data, the extent to which a received frame is correctly aligned with respect to the clock at the receiver.
2. The state in which the frame of the receiving equipment is synchronized with that of the received signal. [T1.107-1988]

See cyclic redundancy check.

The time between the beginning of a frame and the end of that frame.
Note: For fixed-length frames, at a fixed data rate, frame duration is constant.

Synonym frame rate.

A device that can seize and record a single frame of video information out of a sequence of many frames.

The process of comparing one sequence of frames with another sequence of frames in order to determine the correspondence between frames in each sequence and the correspondence of individual frames.
Note: One means to test the correspondence between two video frames is to compare their digital representations on a pixel by pixel basis, and summarizing over all pixels as the… (Read More →)

Bits (binary digits) that are added at regular intervals to a digital signal at the sending end of a digital link and used to provide network functions such as framing, operations, administration, and maintenance. [T1.107-1988]

The distance, time, or number of bits between corresponding points, i.e., significant instants, in two consecutive frames. [From Weik '89]

The number of frames transmitted or received per unit time.
Note 1: The frame rate is usually expressed in frames per second.
Note 2: In television transmission, the frame rate must be distinguished from the field rate, which in the NTSC and other systems, is twice the frame rate. Synonym frame frequency.
