APPARATUS AND METHOD FOR RECEIVING BROADCAST CONTENT FROM A BROADCAST STREAM AND AN ALTERNATE LOCATION

摘要

According to embodiments of the present invention, a receiver obtains service location information which defines current and next sources from which a data stream can be obtained, and a switching time at which the source of the data stream will be switched from the current source to the next source. Before the switching time, the receiver receives the data stream from the current source, and after the switching time, the receiver receives the data stream from the next source. The next source can be defined in initial service location information, or in updated service location information obtained later. An apparatus and method for providing the service location information are also disclosed. In some embodiments, a broadcast provider and/or the receiver can execute a method to compensate for an IP delay experienced by the receiver.

主权项

1. A digital broadcasting receiver comprising:
a broadcast content receiving module arranged to receive broadcast content from a multiplexed broadcast stream and an alternate location, wherein the broadcast content corresponds to a broadcast channel and comprises a data stream; and a controller arranged to obtain service location information including current source information and switching time information, the current source information identifying one of the broadcast stream and the alternate location as a current source from which the data stream can be obtained, and the switching time information identifying a time at which the source of the data stream will be switched, wherein the controller is further arranged to obtain next source information identifying the other one of the broadcast stream and the alternate location as the next source from which the data stream can be obtained, and to control the broadcast content receiving module to receive the data stream from the current source before the identified time and to receive the data stream from the next source after the identified time.
