  • Page 18: Glossary Of Terms And Abbreviations

    General Information 1.5 Glossary of Terms and Abbreviations Term 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.
  • Page 19 Term Ethernet The widely-used LAN technology specified by IEEE standard 802.3 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.
  • Page 20 General Information Term 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.

    Installation Mounting of the equipment in a rack should be such that a hazardous condition is not produced by uneven loading. This unit is not very heavy, but total rack loading must be considered. Also, do not rest any unsupported equipment on your Unity 4600 . Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits could have on overcurrent protection and supply wiring.
