Abstract

Systems and methods are provided in which an origination station broadcasts a broadcast program to at least one of a plurality of destination stations. A first destination station (or a first group of destination stations) receives a first registration period parameter from the origination station. The first registration period parameter specifies a first period during which the first destination station must register with the origination station. The first destination station may block any attempted registration request that occurs outside the first period. Alternatively, the origination station can deny any attempted registration request by the first destination station that occurs outside the first period. If the registration request from the first destination station is sent before the first period begins, then the destination station can periodically request registration until a request is sent within the first period.

Claims

1. An apparatus, comprising:

means for receiving a first registration period parameter from at least one origination station, wherein the first registration period parameter specifies a first period during which a first destination station is allowed to register with the origination station in order to correctly receive a broadcast session; and

means for blocking any attempted registration request that occurs outside the first period.

2. The apparatus of claim 1, further comprising:

means for requesting registration until a registration request is sent within the first period, if the registration request from the apparatus is sent before the first period begins.

3. The apparatus of claim 2, wherein the first registration period parameter is communicated to the first destination station at a first time, and wherein a second registration period parameter is communicated to other destination stations at a second time.
