It's all digital now, lossless compression.

一个美好的新世界。

Both run-length encoding and dictionary coders are lossless compression techniques.

游程编码和字典编码器都是无损压缩技术。

A compression technique that has this characteristic is called lossless compression, because we don't lose anything.

具有这种特性的压缩技术称为无损压缩，因为我们不会丢失任何东西。

Let's take a look at another type of lossless compression, where blocks of data are replaced by more compact representations.

让我们看一下另一种无损压缩，其中数据块被更紧凑的表示形式所取代。
