A type of analogue recording which records and reproduces data in the electrical form of its source.
Industry:Entertainment
The sound which reaches a mike or listener without hitting or bouncing off any obstacles.
Industry:Entertainment
A method of recording directly to the cutting head of the audio disc cutter, eliminating the magnetic recorder in the sequence, typified by no tape hiss.
Industry:Entertainment
An antenna that directs most of its signal strength in a specific direction rather than at equal strength in all directions.
Industry:Entertainment
One whose sensitivity to sound varies with direction. Such microphones can be aimed so their most sensitive sides face the sound source, while their least sensitive sides face sources of noise or other undesired sound.
Industry:Entertainment
Light that emanates from a constant direction with a constant intensity. This is called the infinite light source.
Industry:Entertainment
A container in the file system in which you store other directories and files.
Industry:Entertainment
A CRT watched directly, as opposed to one projecting its image on a screen.

A) Used in JPEG and the MPEG, H.261 and H.263 video compression algorithms, DCT techniques allow images to be represented in the frequency rather than time domain.
Images can be represented in the frequency domain using less information than in the time domain.
b) A mathematical transform that can be perfectly undone and which is useful in image compression.
c) Many encoders perform a DCT on an eight-by-eight block of image data as the first step in the image compression process. The DCT converts the video data from the time domain into the frequency domain. The DCT takes each block, which is a 64-point discrete signal, and breaks it into 64 basis signals. The output of the operation is a set of 64 basis-signal amplitudes, called DCT coefficients. These coefficients are unique for each input signal. The DCT provides a basis for compression because most of the coefficients for a block will be zero (or close to zero) and do not need to be encoded.
