Video processing system with conditional access module and methods for use therewith

1. A video processing system comprising:

a video device that generates a request corresponding to video content triggered by a channel change to a new broadcast channel; and

a network conditional access module, coupled to the video device via a public telecommunications network, that generates a video signal for transmission to the video device via the public telecommunications network with a first authentication during a first time period, wherein a beginning of the first time period is triggered by the channel change, wherein a length of the first time period corresponds to authentication latency, and wherein the conditional access module terminates transmission of the video signal from the public telecommunications network to the video device when the request is not authenticated via a second authentication that is more stringent that the first authentication, during the first time period.

2. The video processing system of claim 1 wherein the channel change from a previous broadcast channel to the new broadcast channel.

3. The video processing system of claim 1 wherein the network conditional access module authenticates the request based on subscription data corresponding to a user of the video device.

4. The video processing system of claim 1 wherein the network conditional access module authenticates the request based on authentication data corresponding to the video device.

5. The video processing system of claim 1 wherein the network conditional access module authenticates the request based on conditional access data.

6. The video processing system of claim 1 wherein the video device is a wireless device and the video processing system further comprises:

a wireless access device, coupled to wirelessly receive the request from the video device and to transmit the request to the network conditional access module via the public telecommunications network.

7. A method comprising:

receiving a request from a video device, the request corresponding to video content triggered by a channel change to a new broadcast channel;

generating a video signal for transmission with a first authentication to the video device via a public telecommunications network during a first time period in response to the request wherein a beginning of the first time period is triggered by the channel change, wherein a length of the first time period corresponds to an expected authentication latency; and

terminating transmission of the video signal from the public telecommunications network to the video device when the request is not authenticated during the first time period via a second authentication that is more stringent that the first authentication.

8. The method of claim 7 wherein the channel change from a previous broadcast channel to the new broadcast channel.

9. The method of claim 7 further comprising:

authenticating the request based on subscription data corresponding to a user of the video device.

10. The method of claim 7 further comprising:

authenticating the request based on authentication data corresponding to the video device.

11. The method of claim 7 further comprising:

authenticating the request based on conditional access data.

12. The method of claim 7 wherein the method further comprises:

transmitting the request to a conditional access module via the public telecommunications network.

13. The video processing system of claim 1 wherein the first time period is less than 10 seconds.

14. The method of claim 7 wherein the first time period is less than 10 seconds.

15. A video processing system comprising:

a network interface that receives a request, from a video device via a public telecommunications network, corresponding to video content triggered by a channel change to a new broadcast channel; and

a network conditional access module, coupled to the network interface, that generates a video signal for transmission to the video device via the public telecommunications network with a first authentication during a first time period, wherein a beginning of the first time period is triggered by the channel change, wherein a length of the first time period corresponds to authentication latency, and wherein the conditional access module terminates transmission of the video signal from the public telecommunications network to the video device when the request is not authenticated via a second authentication that is more stringent that the first authentication, during the first time period.

16. The video processing system of claim 15 wherein the channel change from a previous broadcast channel to the new broadcast channel.

17. The video processing system of claim 15 wherein the network conditional access module authenticates the request based on subscription data corresponding to a user of the video device.

18. The video processing system of claim 15 wherein the network conditional access module authenticates the request based on authentication data corresponding to the video device.

19. The video processing system of claim 15 wherein the network conditional access module authenticates the request based on conditional access data.

20. The video processing system of claim 15 wherein the video device is a wireless device and the video processing system further comprises:

a wireless access device, coupled to wirelessly receive the request from the video device and to transmit the request to the network conditional access module via the public telecommunications network.
