Abstract

Embodiments of a method executable by an adaptive stream concatenation server to deliver a concatenated transport stream to a video distribution system are provided, as are embodiments of adaptive stream concatenation servers. In one embodiment, the method includes receiving an adaptive media stream containing television programming in an adaptive packet format at the adaptive stream concatenation server via a digital network. The contents of the adaptive media stream are concatenated by the adaptive stream concatenation server to create a concatenated transport stream containing the television programming in a streaming format different from the adaptive packet format and compatible with the video distribution system. The concatenated transport stream containing the television programming is then transmitted in the streaming format to the video distribution system.

Claims

1. A method for implementing a receiver to receive an adaptive stream, the method comprising:

receiving, at the receiver, the adaptive stream comprising a concatenated transport stream wherein the receiver comprises a set-top-box (STB);

receiving at the STB a first adaptive media stream containing television programming configured in an adaptive packet format from a streaming server;

concatenating content of the first adaptive media stream in a compatible format with the STB;

configuring in a concatenated transport stream the content for receipt at the STB wherein the content contains the television programming in a streaming format different from the adaptive packet format; and

receiving, at the STB, the content in the concatenated transport stream containing the television programming in the streaming format.

2. The method of claim 1 further comprising receiving a second adaptive media stream containing television programming in an adaptive packet format at the STB, and wherein concatenating comprises concatenating the contents of the first and second adaptive media streams prior to receipt at the STB to create the concatenated transport stream containing the television programming.

3. The method of claim 2 wherein the first adaptive media stream contains at least a first television channel, wherein the second adaptive media stream contains at least a second television channel, and wherein the concatenated transport stream contains a multi-channel television programming.

4. The method of claim 1 further comprises sending by the STB a request for packets of an adaptive media stream.

5. The method of claim 4 wherein the packets are requested from one of a group consisting of a network server, the STB and an adaptive encoder.

6. The method of claim 1 wherein the television programming comprises a plurality of television channels, wherein the receiving comprises receiving a separate adaptive media stream for each of the plurality of channels, and wherein the concatenating comprises concatenating the contents of each of the separate adaptive media streams into separate transport streams.

7. The method of claim 1 wherein the concatenated transport stream is modulated for radio frequency (RF) delivery to a cable television headend associated with a television distribution system.

8. The method of claim 1 further comprising encrypting the concatenated transport stream prior to sending the concatenated transport stream to the STB.

9. The method of claim 1 further comprising receiving by the STB multiple adaptive media streams based on subscriptions to playlist files.

10. The method of claim 1 further comprising configuring the concatenated transport stream as a multicast Internet Protocol (“

IP”

) stream.

11. The method of claim 10 wherein receiving comprises routing the multicast IP stream via a headend distributor to the STB.

12. The method of claim 10 wherein multicast IP stream is encapsulated in accordance with a protocol selected from a group consisting of User Datagram Protocol or Real-time Transport Protocol.

13. A receiver apparatus configured to receive an adaptive concatenated stream to provide television programming comprising:

a set-top box (STB) configured to interface with a digital network;

a processor contained in the STB configured to;

receive an adaptive stream comprising a concatenated transport stream, the adaptive stream comprising a first adaptive media stream containing television programming in an adaptive packet format via the digital network and configured by a streaming server wherein the streaming server is in communication with the STB;

receive concatenated content of the first adaptive media stream in a compatible format with the STB; and

receive the concatenated content in a concatenated transport stream wherein the concatenated content contains television programming in a streaming format different from the adaptive packet format.

14. The receiver apparatus of claim 13 wherein the first adaptive media stream contains at least a first television channel, and wherein the processor is further configured to:

receive a second adaptive media stream containing at least a second television channel in an adaptive packet format of the digital network; and

receive concatenated contents of the first and second adaptive media streams by a concatenated transport stream containing a multi-channel television programming for transmission to the video distribution system.

15. The receiver apparatus of claim 13 wherein the processor is further configured to receive packets of the adaptive media stream from an adaptive stream concatenation server.

16. The receiver apparatus of claim 13 wherein the processor is further configured receive a modulated transport stream for radio frequency (RF) delivery via a cable television headend associated with the STB.

17. The receiver apparatus of claim 13 wherein the processor is further configured to:

receive the concatenated transport stream as a multicast Internet Protocol (“

IP”

) stream; and

in response to the multicast IP stream routed to a headend distributor, connect with the headend distributor to present the multicast IP stream.

18. The receiver apparatus of claim 14 wherein the STB is connected to an streaming server configured to concatenate content and which is implemented in a residential gateway device located within a user'"'"'s home.

19. The receiver apparatus of claim 18 wherein the residential gateway device comprises a satellite receiver.

20. A system to receive a concatenated transport stream executable by an adaptive stream concatenation server to at least one television receiver, the system comprising:

a plurality of adaptive media streams each containing different television channels in an adaptive packet format at the adaptive stream concatenation server via a digital network;

a plurality of receivers configured to receive contents of the plurality of adaptive media streams configured by an adaptive stream concatenation server as a multicast Internet Protocol (“

IP”

) stream containing a multi-channel television programming in a streaming format different from the adaptive packet format and compatible with the video distribution system wherein the plurality of receivers at least comprise set-top boxes;

wherein the multicast IP stream containing the multi-channel television programming is encrypted; and

the encrypted multicast IP stream received by each STB contains television programming in the streaming format to the STB of a television distribution system for distribution to the plurality of television receivers.
