Method of prioritizing entries within a service group map to facilitate auto channel discovery

1. A method for creating an SGM, wherein said SGM is utilized by a DHCT, and wherein said DHCT requires discovery of a SGID assigned to said DHCT, said method comprising the steps of:

providing a plurality of entries, each said entry comprising a frequency, a tabulated TSID, and a SGID associated with one another, and said SGM having one or more occurrences of the same said frequencies; and

prioritizing each of said entries adjacent to one another such that said frequencies associated with first occurrences of each said SGID have the highest priority, such that all identical frequencies in said SGM are not grouped together and such that all identical SGIDs in said SGM are not grouped together.

2. The method of claim 1 wherein said first occurrences of each said SGID are distinguishable from one another.

3. The method of claim 1 wherein said prioritizing step is performed by basing said priority on other than the lowest said frequency associated with each said SGID.

4. The method of claim 1 wherein said prioritizing step is performed by basing said priority on other than the highest said frequency associated with each said SGID.

5. The method of claim 1 wherein said prioritizing step is performed by basing said priority on other than the number of subscribers associated with each said frequency.

6. The method of claim 1 wherein said prioritizing step is performed by basing said priority on other than the number of DHCTs associated with each said frequency.

7. The method of claim 1 further comprising the step of prioritizing said frequencies of said SGM based upon said frequencies associated with said first occurrences of said SGID being the lowest for which said TSIDs are available to said DHCT.

8. The method of claim 1 further comprising the step of prioritizing said frequencies of said SGM based upon said frequencies associated with said first occurrences of said SGID being the highest for which said TSIDs are available to said DHCT.

9. The method of claim 1 further comprising the step of prioritizing said frequencies of said SGM based upon the number of subscribers associated with said frequencies associated with said first occurrences of said SGID.

10. The method of claim 1 further comprising the step of prioritizing said frequencies of said SGM based upon the number of DHCTs associated with said frequencies associated with said first occurrences of said SGID.

11. The method of claim 1 wherein said entries are arranged relative to one another such that first occurrences of each said SGID are interspersed alternately with one another.

12. The method of claim 1 wherein said entries are arranged relative to one another such that said first occurrence of each said SGID is before a subsequent occurrence of any of said SGIDs except when one of said frequencies associated with said first occurrence of one of said SGIDs is the same as a subsequent occurrence of any other of said SGIDs.

13. A cable system having a headend, the headend configured to provide an SGM to a DHCT, wherein the cable system comprises:

a DHCT, wherein a SGM is utilized by said DHCT, and wherein said DHCT requires discovery of a SGID assigned to said DHCT, and

wherein said SGM comprises:

a plurality of entries, each said entry comprising a frequency, a tabulated TSID, and a SGID associated with one another, said SGM having one or more occurrences of the same said frequencies, and said entries arranged adjacent to one another based upon priority such that said frequencies associated with first occurrences of each said SGID have the highest priority, such that all identical frequencies in said SGM are not grouped together and such that all identical SGIDs in said SGM are not grouped together.

14. The SGM of claim 13 wherein said first occurrences of each said SGID are interspersed alternately with one another.

15. The SGM of claim 13 wherein said entries are arranged such that said frequencies corresponding with said first occurrences of said SGIDs represent the lowest frequencies for which said TSIDs are available to said DHCT.

16. The SGM of claim 15 wherein the frequencies corresponding with second occurrences of said SGIDs represent the second lowest frequencies for which said TSIDs are available to said DHCT.

17. The SGM of claim 13 wherein said entries are arranged such that said frequencies corresponding with said first occurrences of said SGIDs represent the highest frequencies for which said TSIDs are available to said DHCT.

18. The SGM of claim 17 wherein said entries are arranged such that said frequencies corresponding with second occurrences of said SGIDs represent the second highest frequencies for which said TSIDs are available to said DHCT.

19. The SGM of claim 13 wherein said entries are arranged such that said frequencies associated with the highest number of subscribers correspond with said first occurrences of each of said SGIDs.

20. The SGM of claim 19 wherein said entries are arranged such that said frequencies associated with the second highest number of subscribers correspond with second occurrences of each of said SGIDs.

21. The SGM of claim 13 wherein said entries are arranged such that said frequencies associated with the highest number of DHCTs correspond with said first occurrences of each of said SGIDs.

22. The SGM of claim 21 wherein said entries are arranged such that said frequencies associated with the second highest number of DHCTs correspond with second occurrences of each of said SGIDs.

23. The SGM of claim 13 wherein said entries are arranged relative to one another such that said first occurrence of each said SGID is before a subsequent occurrence of any of said SGIDs except when one of said frequencies associated with said first occurrence of one of said SGIDs is the same as a subsequent occurrence of any other of said SGIDs.
