When to use lossy data compression. There are times when you don’t need or want all of the data, such as jitter from IoT and network appliances.

Lossy compression is never used for business data and text, which demand a perfect restoration (see lossless compression). See data compression , codec examples , JPEG , MPEG and MP3 .

Compression is a way of encoding digital data so it takes up less storage space and requires less network bandwidth to be transmitted. There are two basic types of compression: lossy methods, in ...

The IP surveillance market has boomed over the past decade with dozens, if not hundreds, of new players emerging and traditional CCTV manufacturers expanding into networked technologies ...

There are two categories of data compression. The first reduces the size of a single file to save storage space and transmit faster. The second is for storage and transmission convenience. The ...

Data Compression Strategies Table 27-1 shows two different ways that data compression algorithms can be categorized. In (a), the methods have been classified as either lossless or lossy. A lossless ...

Lossy compression methods are in fact quite useful. JPEG compression, for example, is a good example of discarding data that isn’t readily perceived by humans to make a smaller file, but that ...

I’m leading two ECP software projects. The first one is called VeloC (Very Low Overhead transparent multilevel Checkpoint/restart), and it’s related to fault tolerance. The second one is EZ (Fast, ...

We have already discussed a simple method of lossy data compression, coarser sampling and/or quantization (CS&Q in Table 27-1). This involves reducing the number of bits per sample or entirely discard ...
