- boundary value analysis — (programming) A test data selection technique in which values are chosen to lie along data extremes. Boundary values include maximum, minimum, just inside/outside boundaries, typical values, and error values.

- broadcast quality video — (communications, multimedia) Roughly, video with more than 30 frames per second at a resolution of 800 x 640 pixels. The quality of moving pictures and sound is determined by the complete chain from camera to receiver. Relevant factors are the colour temperature of the lighting, the balance of the red, green and blue vision pick-up tubes to produce the correct display colour temperature (which will be different) and the gamma pre-correction to cancel the non-linear characteristic of cathode-ray tubes in television receivers. The resolution of the camera tube and video coding system will determine the maximum number of pixels in the picture. Different colour coding systems have different defects. The NTSC system (National Television Systems Committee) can produce hue errors. The PAL system (Phase Alternation by Line) can produce saturation errors. Television modulation systems are specified by ITU CCIR Report 624. Low-resolution systems have bandwidths of 4.2 MHz with 525 to 625 lines per frame as used in the Americas and Japan. Medium resolution of 5 to 6.5 MHz with 625 lines is used in Europe, Asia, Africa and Australasia. High-Definition Television (HDTV) will require 8 MHz or more of bandwidth. A medium resolution (5.5 MHz in UK) picture can be represented by 572 lines of 402 pixels. Note the ratio of pixels to lines is not the same as the aspect ratio. A VGA display (480n lines of 640 pixels) could thus display 84% of the height of one picture frame. Most compression techniques reduce quality as they assume a restricted range of detail and motion and discard details to which the human eye is not sensitive. Broadcast quality implies something better than amateur or domestic video and therefore can't be retained on a domestic video recorder. Broadcasts use quadriplex or U-matic recorders. The lowest frame rate used for commercial entertainment is the 24Hz of the 35mm cinema camera. When broadcast on a 50Hz television system, the pictures are screened at 25Hz reducing the running times by 4%. On a 60Hz system every five movie frames are screened as six TV frames, still at the 4% increased rate. The six frames are made by mixing adjacent frames, with some degradation of the picture. A computer system to meet international standard reproduction would at least VGA resolution, an interlaced frame rate of 24Hz and 8 bits to represent the luminance (Y) component. For a component display system using red, green and blue (RGB) electron guns and phosphor dots each will require 7 bits. Transmission and recording is different as various coding schemes need less bits if other representations are used instead of RGB. Broadcasts use YUV and compression can reduce this to about 3.5 bits per pixel without perceptible degradation. High-quality video and sound can be carried on a 34 Mbaud channel after being compressed with ADPCM and variable length coding, potentially in real time.

- conservative evaluation — (programming) Under this parallel evaluation strategy, no evaluation is started unless it is known to be needed. The opposite of conservative evaluation is speculative evaluation.
- constructive cost model — (programming) (COCOMO) A method for estimating the cost of a software package, proposed by Dr Barry Boehm. The Basic COCOMO Model estimates the effort required to develop software in three modes of development (Organic Mode, Semidetached Mode, or Embedded Mode) using only DSIs as an input. The Basic model is good for quick estimates. The Intermediate Model extends the Basic Model with an Effort Adjustment Factor (EAF) and different coefficients for the effort equation. The user supplies settings for cost drivers that determine the effort and duration of the software projects. It also allows DSI values and cost drivers to be chosen for individual components instead of for the system as a whole. The Detailed COCOMO Model uses effort multipliers for each phase of the project and provides a three-level product hierarchy and has some other capabilities such as a procedure for adjusting the phase distribution of the development schedule.

- university of edinburgh — (body, education) A university in the centre of Scotland's capital. The University of Edinburgh has been promoting and setting standards in education for over 400 years. Granted its Royal Charter in 1582 by James VI, the son of Mary Queen of Scots, the University was founded the following year by the Town Council of Edinburgh, making it the first post-Reformation university in Scotland, and the first civic university to be established in the British Isles. Known in its early years as King James College, or the Tounis (Town's) College, the University soon established itself internationally, and by the 18th century Edinburgh was a leading centre of the European Enlightenment and one of the continent's principal universities. The University's close relationship with the city in which it is based, coupled with a forward-looking, international perspective, has kept Edinburgh at the forefront of new research and teaching developments whilst enabling it to retain a uniquely Scottish character. Edinburgh's academics are at the forefront of developments in the study and application of languages, medicine, micro-electronics, biotechnology, computer-based disciplines and many other subjects. Edinburgh's standing as a world centre for research is further enhanced by the presence on and around University precincts of many independently-funded, but closely linked, national research institutes Address: Old College, South Bridge, Edinburgh, Scotland EH8 9YL, UK.
