    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.
