Annex 5 : Supported file formats
A codec (encoder/decoder) is a technology for compressing and decompressing data. Codecs convert digital signals
to and from analog, and can be implemented in software, hardware, or a combination of both. Standard codecs are
used to encode and compress audio and video data for streaming across networks.
