Adherent Data Analyzer: looks at transport streams and their content and displays the bit rate, repetition rates, structure, syntax and semantics of data

All source formats are transmitted using the same nominal 1.485Gb/s serial bit rate. The capacity for carrying ancillary data varies from format to format.

Since the beginning of telecommunications in the early 20th century, telcom carriers and broadcasters have striven to transmit as much information as possible while conserving the limited bandwidth of the media they use — that is, to maximize throughput. They have succeeded in this effort by developing various techniques that can be grouped under the term “multiplexing.”
