Table 1.3: Glossary of Terms

 

 

Term

Definition

 

 

Ad avail, digital

The opportunity for a local program splicer to insert local content in the MPEG PES streams in

 

substitution for “regular” network-distributed programming. The avail is bounded by “splice out” and

 

“splice in” points. "Splice points" are seamless insertion points (located for the splicer by DPI

 

messages) where the compressed stream may be broken and substituted without frame-by-frame

 

interruption of video.

 

 

Ad avail, analog

The opportunity for local users to switch from the network-supplied programming to locally-

 

generated content (commercials). This is signaled by use of DTMF tones or closures of cue relays.

 

 

Alarm

A condition or notification of a condition that prevents proper U4600 functioning.

 

 

Application

The main host software which sets up the unit hardware, runs the process of acquiring transport

Software

stream sources, sets up and monitors the demux and decompression processes, monitors unit

 

operations, and interfaces with the network and local users.

 

 

ASI (or DVB-ASI)

An “asynchronous” bit-serial physical interface for transport streams. Transmitting and receiving

 

functions are designed such that the time relationships between all packets and their timing

 

references are unchanged.

 

 

Audio Language

Legacy 3-character MPEG descriptor applied to a program’s audio streams. It was originally

Descriptor

allocated to designate languages, but is now used for generic identification.
