Method for searching ordered entries in a service group map to facilitate auto channel discovery

摘要

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.
