General Information 1.5 Glossary of Terms and Abbreviations 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

Unity 4600 User’s Manual Term Definition Ethernet The widely-used LAN technology specified by IEEE standard 802.3 IRD Integrated Receiver-Decoder. A product which features a "receiver" to extract transport streams from satellite-borne carriers and a companion "decoder" to decompress MPEG elementary streams (from within said transport streams) in order to recreate the original audio/video/data signals. The Unity 4600 is an IRD. Keep-alives Simple COMPEL network messages, addressed to "all", b

General Information Term Definition PMT Program Map Table. A PSI table within an MPEG transport stream which cross-references a program (or programs) against all the PIDs that bear its component streams (such as audios, video, DPI, PCR, etc.). IRDs need this table to decode the compressed components of that program. Presets Table A non-volatile table of unit presets. This table is used for either automatic recoveries or as a shorthand method to quickly reconfigure the unit. The presets table
