The processing of sampled digital signals in order to reduce their bit-rate (the number of bits per second) so that they may pass through a lower bit-rate capacity channel. Hence in TV terms it means the processing of digital component signals to reduce t. Synonyms: Bit Rate Reduction; Signal Compression
A process of translating analog signals into a digital code that has a reduced bit rate than the original signal would have. It does this by removing redundant and irrelevant information.
The process by which a codec reduces the amount of data needed to be transmitted to represent the original analog signal. Used in audio and in video.
The reduction of the information needed to be broadcast (video, audio or data) giving minimum loss of received quality so as to make maximum use of the available transmission capacity. Thus, several digitally compressed TV channels can be transmitted in the space required for a single uncompressed analog TV channel. The main way that compression works is by eliminating some of the redundant data in the signal.
A collection of techniques used to compress a stream of computer-generated digital information, allowing information to be sent using less bandwidth.
Digital compression uses the same principals as Digital Audio Broadcasting. The video signal is compressed into MPEG format, where it takes up less space. It is then beamed to a dish where it is the receivers job to decode it. This is same technology used for DVD. The compression allows for a smaller dish size and is the reason that DBS is replacing the larger satellite dishes.
Techniques used to compress digital signals to allow transmission within a much smaller bandwidth.
Digital compression is a process of translating video images into a digital code. Its purpose is to take up less transmission space than the original signal would have, allowing more channels per satellite transponder.
Encoding data or digital information to use less storage space or to require less bandwidth for efficient transmission.
A process of translating video images into a digital code which takes up less transmission space than the theatrical signal would have. This allows more channels per satellite transponder: from four-to-one for live video to eight-to-one for film.
A technique used to reduce the number of digits to required to represent a signal thereby increasing the number of channels able to be carried by a single transmission medium.
A way of reducing the number of bits (ones and zeros) in a digital signal by using mathematical algorithms to eliminate redundant information thereby reducing the space it occupies when being transmitted or recorded.
Squeezing digital information (like pictures or sound) into a smaller space to be able to transmit more quantity.
An engineering technique for converting a cable TV signal into a digital format which may then be processed in a manner that requires a smaller portion of spectrum for its transmission. This compressed format allows many channels to be carried in the bandwidth normally required for one signal. This format can also be easily stored and manipulated.
A technique for converting digital video to a lower data rate by eliminating redundant information.
Digital compression involves the use of algorithms to reduce the bandwidth necessary to store or transmit a digital video signal or other digital information.
