Abstract

Methods, systems, and techniques for providing near real-time streaming of broadcast content, such as television, using peer-to-peer techniques are provided. Example embodiments provide a P2P Streaming Internet Television System (“PSITS”), which enables television content to be encoded, encrypted, and distributed to one or more Internet-ready player computing devices (players) using peer-to-peer computing technology in a closed secure environment. In one embodiment, the PSITS comprises one or more encoders, one or more trackers, one or more seeders, and one or more players, which communicate using a secure protocol in a closed system, which insures the integrity of encoded encrypted signal data to point of presentation on the players. This abstract is provided to comply with rules requiring an abstract, and it is submitted with the intention that it will not be used to interpret or limit the scope or meaning of the claims.

1. A method in a computing environment for secured delivery of streamed audio and/or video content to one or more network-ready devices, comprising:

sending electronic instructions to direct the transmission of data from an encoded encrypted audio and/or video signal that contains the streamed audio and/or video content from one or more encoders to one or more seeder computing systems that store the transmitted data; and

sending electronic instructions to direct one of the one or more network-ready devices to electronically receive from one of the one or more seeder computing systems a buffer of an initial portion of stored transmitted data of the encoded encrypted signal containing a portion of the streamed audio and/or video content and to electronically receive subsequent portions of the stored transmitted data from one or more peer network-ready devices or from the one of the one or more seeder computing systems.

2. The method of claim 1 wherein the sending of the electronic instructions is performed by at least one of one or more tracker computing systems.

3. The method of claim 1 wherein the audio and/or video signal contains live broadcast television channel content.

4. The method of claim 1 wherein the audio and/or video signal contains archived audio and/or video content.

5. The method of claim 1 wherein the initial portion of the encoded encrypted signal is an 100 second segment of the signal.

6. The method of claim 1 wherein it is determined whether to direct the one of the one or more network-ready devices to receive subsequent portions of the signal from the one or more peer network-ready devices or from the one of the one or more seeder computing systems based upon testing performance parameters related to sending or receiving the initial portion of the encoded encrypted signal by the one of the one or more network-ready devices.

7. The method of claim 1, further comprising:

electronically receiving tracking information from the one of the one or more network-ready devices.

8. The method of claim 1 wherein the tracking information tracks information relating to what has been viewed on the one of the one or more network-ready devices.

9. The method of claim 1, further comprising electronically providing encoding and/or encryption parameters to the one or more encoders.

10. The method of claim 1, further comprising electronically providing one or more decryption keys to the one of the one or more network-ready devices to enable the one of the one or more network-ready devices to decrypt received portions of the stored transmitted data that contains the encoded encrypted signal.

11. A computer-readable memory medium containing computer instructions that are configured to, when executed, to control a computer system to securely deliver streamed audio and/or video content to one or more network-ready players by performing a method comprising:

sending instructions to direct the transmission of data from an encoded encrypted audio and/or video signal comprising the streamed audio and/or video content from one or more encoders to one or more seeders that store the transmitted data; and

sending instructions to direct one of the one or more network-ready players to receive from one of the one or more seeders a buffer of an initial portion of the stored transmitted data that contains a portion of the encoded encrypted audio and/or video signal and to receive subsequent portions of the stored transmitted data from one or more peer network-ready players or from the one of the one or more seeders.

12. A tracking computing system comprising:

a memory;

encoder logic, stored in the memory, and configured when executed on a computer processor to communicate with one or more encoders to direct transmission of an encoded encrypted audio and/or video signal from the one or more encoders to be stored as encoded encrypted data on one or more seeder computing systems; and

player device logic, stored in the memory, and configured when executed on a computer processor to communicate with one or more player devices to receive from one of the one or more seeder computing systems a buffer of an initial portion of the stored encoded encrypted data and to receive subsequent portions of the stored data from one or more peer player devices or from the one of the one or more seeder computing systems.

13. A computer-readable memory medium containing instructions configured, when executed, to control a computing system propagate a broadcast signal containing secure streamed audio and/or video content by performing a method comprising:

receiving in near real-time signal data from encoded encrypted audio and/or video broadcast signal data from one or more encoders;

storing the received near real-time signal data in encoded encrypted form in a computing memory;

receiving electronic instructions from a second computing system regarding distribution of portions of the received near real-time signal data; and

distributing in encoded encrypted form portions of the stored data in near real-time to one or more player computing systems in accordance with the received electronic instructions.

14.
