PROVIDING TELEVISION BROADCASTS OVER A MANAGED NETWORK AND INTERACTIVE CONTENT OVER AN UNMANAGED NETWORK TO A CLIENT DEVICE
摘要
<p>A client device receives a broadcast content signal containing an interactive identifier over a managed network. The interactive identifier may be a trigger that is included in a header or embedded within the digital video data. In response to identification of the trigger, the client device sends a user request for interactive content over an unmanaged network. For example, the managed network may be a one-way satellite television network, IP-television network or cable television network and the unmanaged network may be the Internet. The client device switches between receiving data from the managed network to receiving data from the unmanaged network. Video encoding parameters of the interactive content are varied based on detected variations in the audio transmission bandwidth.</p>
