41. The method as described in claim 1, wherein said selecting said service location manager comprises:

maintaining a record comprising identifying information for a set of service location managers among said plurality of service location managers; and

selecting said service location manager in a round robin manner from said record.

42. The method as described in claim 1, wherein said selecting said service location manager comprises a comparison of processing loads of at least two service location managers among said plurality of service location managers.

43. The method as described in claim 1, wherein said selecting said service location manager comprises a comparison of available resources of a first set of service providers supervised by said service location manager and available resources of a second set of service providers supervised by a second service location manager.

44. The method as described in claim 1, wherein said selecting said service location manager is based on an estimate of a network communication condition between two entities connected by the network.

45. The method as described in claim 44, wherein said estimate of said network communication condition is associated with said client.

46. The method as described in claim 44, wherein said estimate of said network communication condition is associated with a content source of said streaming media.

47. The method as described in claim 1, wherein said selecting said service location manager is based on one of the group consisting of:

pending service application Ser. No. 10/698,196-5-200313240-1 request queue length of a service location manager, expected latency of a service location manager for assigning said service request, and available network communication bandwidth of a service location manager.

48. The method as described in claim 1, further comprising:

notifying a second service location manager among said plurality of service location managers of the assignment of said service provider to perform said media service component.

49. The method as described in claim 1, further comprising:

notifying a second service location manager among said plurality of service location managers of the completion of performance of said media service component.

50. The method as described in claim 1, further comprising:

a second service location manager assuming the role of said service location manager if said service location manager is determined to be non-responsive.

51. The method as described in claim 1, further comprising:

maintaining a record comprising identifying information of a set of service location managers among said plurality of service location managers, each service location manager of said set of service location managers supervising said service provider; and

notifying said set of service location managers according to said record of said assignment of said service provider to perform said media service component.

52. The method as described in claim 51, wherein said maintaining and said notifying is performed by said service provider or said service location manager.

53. The method as described in claim 1, further comprising:

maintaining a record comprising identifying information of a set of service location managers among said plurality of service location managers, each service location manager of said set of service location managers supervising said service provider; and

notifying said set of service location managers according to said record of the completion of performance of said media service component by said service provider.

54. The method as described in claim 53, wherein said maintaining and said notifying is performed by said service provider or said service location manager.

55. The method as described in claim 1, wherein said service provider is supervised by more than one service location manager among said plurality of service location managers.

2-37. -37. (canceled)

56. A system for providing streaming content to a client device, said system comprising:

a plurality of service location managers;

a plurality of service providers, each service provider capable of performing a service on an item of streaming input content to produce said streaming content; and

a portal providing a first point of contact for said client device, said portal for receiving from said client device a request for performance of said service on an item of streaming input content, said portal for selecting a service location manager to which to provide said request from said plurality of service location managers, said service location manager for receiving said request from said portal and for selecting a service provider from said plurality of service providers and informing said service provider of said assignment to perform said service on said streaming input content to produce said streaming content.

57. The system of claim 56, wherein said portal maintains a record comprising a prioritized listing of at least one service location manager among said plurality of service location managers and selects said service location manager in order of priority according to said prioritized listing.

58. The system of claim 56, wherein said portal maintains a record comprising identifying information of a set of service location managers among said plurality of service location managers and selects said service location manager in a round robin manner from said record.

59. The system of claim 56, wherein said portal selects said service location manager by comparing processing loads of at least two service location managers among said plurality of service location managers.

60. The system of claim 56, wherein said portal selects said service location manager by comparing available resources of a first set of service providers supervised by said service location manager and available resources of a second set of service providers supervised by a second service location manager.
