Many MPEG, DVB, ATSC and DCII tables can contain descriptors which add to the information being sent on these tables. TSReader decodes almost all of these descriptors as shown below. Descriptors are decoded based on the network type that TSReader is currently processing. The following table explains how TSReader recognizes a network type:

The MPEG-7 Audio standard contains description tools for audio describing content. The extraction of low level descriptors is normative and is based on the audio signal itself. With the help of low level descriptors it is possible to search and filter audio content in regard to for e.g. spectrum, harmony, timbre and melody. 2. Low Level Tools.

coding like MPEG-1, MPEG-2 and MPEG-4, is meant to be an standardization of the way to describe multi media content (MPEG -7 1999). The main application for MPEG -7 should be the content -based indexing and retrieval of audio, or of any other media. Content based audio descriptions can prove extremely fruitful in conventional tasks such as audio
