Providers of compression algorithms offer various tradeoffs and advantages associated with their compression techniques.
LZ4是一种无损数据压缩算法,着重于压缩和解压缩速度。
LZ4 is a lossless data compression algorithm that is focused on compression and decompression speed.
由于内部数据压缩算法,确切的数据容量取决于要编码的数据的结构。
Due to internal data compression algorithms the exact data capacity depends on the structure of the data to be encoded.
LZ77是“滑动窗”压缩算法,这个算法后来被证明等同于LZ78中首次出现的显式字典编码技术。
LZ77 is the"sliding window" compression algorithm, which was later shown to be equivalent to the explicit dictionary technique first given in LZ78.
LZ4是一种无损数据压缩算法,着重于压缩和解压缩速度。它属于面向字节的LZ77压缩方案家族。
LZ4 is a lossless data compression algorithm that is focused on compression and decompression speed. It belongs to the LZ77 family of byte-oriented compression schemes.
虽然我们在选择压缩算法的时候强调的是速度而不是压缩的空间,但是这种两步压缩模式效果却惊人的好。
Even thoughwe emphasized speed instead of space reduction when choosing our compression algorithms, this two-pass compression scheme does surprisingly well.
Lempel- Ziv- Storer- Szymanski(LZSS) is a lossless data compression algorithm, a derivative of LZ77, that was created in 1982 by James Storer and Thomas Szymanski.
Because data is stored in an orderly manner,compression works pretty well when fast compression algorithms are used(in 2010 we used QuickLZ, since 2011- LZ4).
Main Profile compression algorithm requires at least 2Mbps can obtain the“HD” visual effects, while the 1080P real-time video should be more than 4Mbsp.
UNOSAT will continue its research activity, jointly with the European Organization for Nuclear Research(CERN), on the use of parallel computing(known as grid technologies)and the development of compression algorithms.
