Abstract

In some embodiments a wireless access point receives digital television content. The digital television content is transmitted in a wireless manner over a wireless network of the wireless access point. The wireless access point may be integrated into a television that redistributes the digital television content. Other embodiments are claimed.

Claims

1. A wireless access point comprising:

one or more digital television receivers to receive digital television content; and

a transmitter to transmit the digital television content in a wireless manner over a wireless network of the wireless access point;

wherein the wireless access point is integrated into a television that redistributes the digital television content and is a digital television hotspot without digital television hardware.

2. The wireless access point of claim 1, wherein the wireless access point is a Wi-Fi access point or an ultra-wideband access point.

3. The wireless access point of claim 1, further comprising an encapsulation device to encapsulate digital television streams into a transport protocol.

4. The wireless access point of claim 1, further comprising a management device to manage digital television discovery, guide, channel selection and session management.

5. The wireless access point of claim 4, wherein the management device is a web server.

6. The wireless access point of claim 3, further comprising a management device to manage digital television discovery, guide, channel selection and session management.

7. The wireless access point of claim 1, further comprising simultaneously transmitting a plurality of digital television streams to one or more platforms via the wireless network.

8. The wireless access point of claim 1, wherein the transmitter is to simultaneously transmit a common digital television stream to two or more platforms via the wireless network.

9. The wireless access point of claim 1, further comprising a content protection module to authenticate one or more devices allowed to receive content over the wireless network and to securely transmit the content to the authenticated one or more devices.

10. The wireless access point of claim 1, further comprising a storage device to store received digital television content.

18. The wireless access point of claim 1, further comprising:

authenticating one or more devices allowed to receive content over the wireless network; and

securely transmitting the content to the authenticated one or more devices.

19. The wireless access point of claim 1, further comprising storing the received digital television content for later transmission over the wireless network.

11. A method comprising:

receiving at a wireless access point digital television content; and

transmitting the digital television content in a wireless manner over a wireless network of the wireless access point;

wherein the wireless access point is integrated into a television set that redistributes the digital television content and is a digital television hotspot.

12. The method of claim 11, wherein the wireless access point is a Wi-Fi access point.

13. The method of claim 11, further comprising encapsulating digital television streams into a transport protocol.

14. The method of claim 11, further comprising managing digital television discovery, guide, channel selection and session management.

15. The method of claim 13, further comprising managing digital television discovery, guide, channel selection and session management.

16. The method of claim 11, further comprising simultaneously transmitting a plurality of digital television streams to one or more platforms via the wireless network.

17. The method of claim 11, further comprising simultaneously transmitting a common digital television stream to two or more platforms via the wireless network.

20. The method of claim 13, wherein the encapsulating encapsulates digital television MPEG-2 streams into Real-time Transport Protocol sessions.

21. The method of claim 20, further comprising exposing the Real-time Transport Protocol sessions through a dynamically discoverable protocol.

22. An article comprising:

a non-transitory computer readable storage medium having instructions thereon which when executed cause a computer to;

encapsulate digital television content received at a wireless access point into a transport protocol for transmission in a wireless manner over a wireless network of the wireless access point;

wherein the wireless access point is integrated into a television set that redistributes the digital television content and is a digital television hotspot.

23. The article of claim 22, wherein the instructions when executed further cause a computer to manage digital television discovery, guide, channel selection and session management.

24. The article of claim 22, wherein the instructions when executed further cause a computer to simultaneously transmit a common digital television stream to two or more platforms via the wireless network.

25. The article of claim 22, wherein the instructions when executed further cause a computer to:

authenticate one or more devices allowed to receive content over the wireless network; and

securely transmit the content to the authenticated one or more devices.

26. The article of claim 22, wherein the instructions when executed further cause a computer to store the received digital television content for later transmission over the wireless network.

27. The article of claim 22, wherein the instructions when executed further cause a computer to encapsulate digital television MPEG-2 streams into Real-time Transport Protocol sessions.

28. The article of claim 27, wherein the instructions when executed further cause a computer to expose the Real-time Transport Protocol sessions through a dynamically discoverable protocol.
