摘要： A simulcast transmission system (150) is disclosed in which a primary (402), a first, and a second transmitter site (302) form a first communication loop (403). The first communication loop (403) has at least a first and a second audio path, each of which are associated with a path identification (ID). The first and the second path IDs are also associated with a set of transmission delay parameters which are stored (401) at both the first and the second transmitter sites. The primary transmitter site (402) detects a location of an inoperative communication link (409) within the first audio path, and switches from the first audio path to the second audio path, whereby the second audio path does not traverse the inoperative communication link. The primary transmitter site (402) then broadcasts (512) a path condition ID to the first and the second transmitter sites. The first and second transmitter sites then retrieve (514) the set of transmission delay parameters associated with the second audio path.

摘要： A method of automatic path map generation (600) for use in a simulcast transmission system is disclosed which has at least three transmitter sites which form a first communication loop (403). The first communication loop has at least a first and a second audio path. A first audio path originates from a primary transmitter site (402), passes first through a first transmitter site, and ends at a second transmitter site. A second audio path originates from the primary site (402), passes first through the second transmitter site, and ends at the first transmitter site. The first audio path is associated with a first path condition, and the second audio path is associated with a second path condition. The method employed includes establishing (601) a logical representation of the simulcast transmission system. Then, selecting (605) one of the at least three transmitter sites for which a path map is to be generated, determines (902) a logical relationship between the primary transmitter site (402) and the selected transmitter site. Knowing this, the primary site (402) is able to calculate (708) a data set identification (ID) for the selected transmitter site that is associated with each of at least the first and the second path conditions. These data set IDs are then recorded (918) for the selected transmitter site, to produce a path map describing a unique association between each of at least the first and the second path conditions and the data set ID.
