Abstract
A method and apparatus for transport encoded asset data and content data, multiplexing the transport encoded content data with a plurality of NULL transport packets to provide “place holder” for the asset data transport packets, and replacing the NULL transport packets with asset data transport packets prior to transmitting the multiplexed transport stream to a set top box.
Claims17
In an information distribution system providing content data and asset data comprising navigational information to at least one subscriber, an apparatus for processing content and asset information comprising:
- means for inserting, within a transport stream including content packets, a plurality of NULL packets;
- means for replacing at least some of said NULL packets with asset packets, said asset packets comprising navigational information for facilitating control and presentation of navigational menus for selecting content at a set-top terminal, said asset packets being associated with said content packets to produce a composite transport stream including said navigational information.
In an information distribution system providing content data and asset data comprising navigational information to at least one subscriber, a method comprising:
- receiving, from a set top terminal, a request for content;
- retrieving a packetized transport stream associated with said request for content, said packetized transport stream having content packets and NULL packets inserted therein;
- replacing at least some of said NULL packets with asset packets, said asset packets comprising said navigational information for facilitating control and presentation of navigational menus for selecting content at the set-top terminal, said asset packets being associated with content packets of said transport stream to produce a composite transport stream including said navigational information;
- and
- generating a mapping table defining content packets associated with asset packets.
