Data compression bbc

What is run length encoding BBC?
One method of lossless compression is run length encoding (RLE).
RLE looks at the data in a file for consecutive runs of the same data.
These runs are stored as one item of data, instead of many..
What is the difference between lossless and lossy BBC?
Lossless compression maintains all the original data but usually leads to lower compression ratios compared to lossy compression.
This means that lossless files are usually larger in size than lossy files..
The aim is to reduce the number of bits used to represent a set of data.
Reducing the number of bits used means that it will take up less storage space and be quicker to transfer.
There are many different compression methods.
Compression methods can be categorised as being lossless or lossy.

Video compression format

Dirac is an open and royalty-free video compression format, specification and system developed by BBC Research & Development.
Schrödinger and dirac-research are open and royalty-free software implementations of Dirac.
Dirac format aims to provide high-quality video compression for Ultra HDTV and beyond, and as such competes with existing formats such as H.264 and VC-1.
