- noun a method of reducing the space taken by data which requires a lot of processing time and power to compress an image or video sequence but is very quick to decompress
- A compression technique in which the time and/or processing power required to decompress differs from that required to originally compress. In data backup, for example, time is saved when compression is faster, as decompression occurs less frequently. In video, processing power and time are economized when decompression occupies less resources, allowing for more sophisticated playback to be delivered. Also called asymmetrical compression.
