First Claim
1. A method for utilizing a SGM when enhanced services are requested through a DHCT requiring discovery of a SGID assigned to said DHCT, said method comprising the steps of:
- providing said SGM comprising a plurality of entries, each said entry comprising a frequency, a tabulated TSID, and a SGID associated with one another;
arranging at least a portion of said entries relative one another such that said tabulated TSIDs corresponding with said arranged portion of said entries are ordered;
providing a PAT having a plurality of TSIDs to be acquired by said DHCT and to define an acquired TSID upon each acquisition occurrence; and
searching in other than a sequential manner said tabulated TSIDs which are ordered within said arranged portion of said entries.

Abstract
A system and method for minimizing timeouts when enhanced services are requested through a digital home communications terminal (DHCT) requiring discovery of a service group identification (SGID) assigned to the DHCT. A service group map (SGM) includes a plurality of entries. Each entry includes a frequency, a tabulated transport stream identification (TSID), and a SGID associated with one another. The SGM has multiple occurrences of the same frequencies. At least a portion of the entries within the SGM are arranged in an ordered manner and then searched in other than a sequential manner to find matching tabulated and acquired TSIDs.
