PROBLEM TO BE SOLVED: To allow for provision of bidirectional content to a client device.SOLUTION: A client device receives a broadcast content signal including a bidirectional identifier over a managed network, in a client device. The bidirectional identifier may be included in a header, or embedded in digital video data. A trigger may have a time component, and may expire after some period. In response to identification of a trigger, a client device transmits a user request for bidirectional content over a non-managed network. For example, the managed network may be a one-way satellite television network, IP television network, or cable television network, and the non-managed network may be the Internet. The client device switches reception of data from the managed network, and reception of data from the non-managed network. |
