Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
The method of transmission of programs or other material that limits its target audience to a specific group rather than the general public.
Industry:Entertainment
Switch used on a cassette recorder to change the amount of bias current required for different types of tapes.
Industry:Entertainment
Circuit operating with feedback, whose inputs are a function of its outputs.
Industry:Entertainment
a) Indicates that signal flow may be in either direction.
Common bidirectional buses are three-state or open collector TTL.
b) In open reel or cassette recorders, the ability to play (and, in some cases, record) both stereo track pairs on a tape by reversing the tape’s direction of motion without removing and replacing the tape reels or cassette.
Industry:Entertainment
A tape transport mechanism in which the tape’s speed and tension are controlled by contact with a capstan at each end of the head assembly.
Industry:Entertainment
A form of compression in which the codec uses information not only from frames that have already been decompressed, but also from frames yet to come. The codec looks in two directions: ahead as well as back. This helps avoid large spikes in data rate caused by scene changes or fast movement, improving image quality.
Compare with Unidirectional Prediction.
Industry:Entertainment
A camera shot that is tightly framed, with its figure or subject filling the screen. Often qualified as medium closeup or extreme closeup.
Industry:Entertainment
An MPEG picture that is coded using motion compensated prediction from past and/or future reference pictures. Motion vectors pointing forwards and backwards are used, and they may point at either I-pictures or P-pictures. The B-pictures provide the highest compression, but demand knowledge of several pictures. Consequently, B-pictures give a higher delay and call for a larger picture memory. B-pictures are never used as a reference in a prediction.
When B-pictures are part of a sequence, the pictures are not sent in chronological order owing to the fact that future P-pictures and/or I-pictures are needed (and therefore must be decoded) for the decoding of B-pictures. The P- and I-pictures have to be sent earlier than the actual point of time to which they relate.
Industry:Entertainment
The magnetic layer of a magnetic tape, consisting of oxide particles held in a binder that is applied to the base film.
Industry:Entertainment
A process which starts with the high-order byte and ends with the low-order byte. Motorola 68000 processors used the big endian format.
