A) The physical length of the tape wound on a reel or on a hub, varying from 213 feet in a C45 cassette to 9200 feet in a roll of instrumentation tape. b) The number of bytes represented by the items whose Length is being described.
Industry:Software
A seamless MPEG-2 concatenation technology developed by the ATLANTIC project in which an MPEG-2 bitstream enters a Mole-equipped decoder, and the decoder not only decodes the video, but the information on how that video was first encoded (motion vectors and coding mode decisions). This “side information” or “metadata” in an information bus is synchronised to the video and sent to the Mole-equipped encoder. The encoder looks at the metadata and knows exactly how to encode the video. The video is encoded in exactly the same way (so theoretically it has only been encoded once) and maintains quality. If an opaque bug is inserted in the picture, the encoder only has to decide how the bug should be encoded (and then both the bug and the video have been theoretically encoded only once). Problems arise with transparent or translucent bugs, because the video underneath the bug must be encoded, and therefore that video will have to be encoded twice, while the surrounding video and the bug itself have only been encoded once theoretically. What Mole cannot do is make the encoding any better. Therefore, the highest quality of initial encoding is suggested.

The luminance range of original scenes varies from outdoor scenes in sunlight with a range possibly exceeding 10000:1, to indoor scenes with controlled lighting, where the range may be reduced to 10:1 or even less. Adjustment of or accommodation to the luminance range, scene is one of the conditions to be evaluated in determining how the scene is to be recorded. It is a test of artistic judgement to place the relative luminances for the objects of interest on a suitable portion of the opto-electronic or opto-photographic transfer function in order to produce the desired subjective quality.
Industry:Software
System of time code that retains all frame numbers in chronological order, resulting in a slight deviation from real clock time.
Industry:Software
The curved glass on a video camera or camcorder that collects light and focuses it.

The Institute of Electrical and Electronics Engineers (IEEE) is the world’s largest technical professional society. Founded in 1884 by a handful of practitioners of the new electrical engineering discipline, today’s Institute includes 46,000 students within a total membership of nearly 320,000 members who conduct and participate in its activities in 150 countries. The men and women of the IEEE are the technical and scientific professionals making the revolutionary engineering advances which are reshaping our world today. And today’s students are the future of the profession. The technical objectives of the IEEE focus on advancing the theory and practise of electrical, electronics, and computer engineering and computer science. To realise these objectives, the IEEE sponsors nearly 800 Student Branches worldwide, as well as scholarships and awareness programs, technical conferences, symposia, and local meetings; publishes nearly 25% of the world’s technical papers in electrical, electronics, and computer engineering; and provides educational programmes to keep its members’ knowledge and expertise state of- the-art. The main IEEE information system is in Piscataway, New Jersey, USA.

The black and white signal (the brightness signal) in colour TV. The luminance signal is formed by combining a proportion of 30% red, 50% green, and 11% blue from the colour signal. This combined output becomes the luminance (brightness/monochrome) signal.
