Abstract

A system for receiving network video includes a remote control with a power control input. A video receiver, controlled by the remote control, powers up or powers down based on a control signal indicating activation of the power control input. The video receiver receives video signals from a gateway or gateway source connected to the video network. The gateway decodes signals received from the network into a format acceptable by the receiver. If the gateway receives a control signal from the remote control indicating activation of the power control input and the gateway is currently in the “on” state, the gateway toggles to the “off” state and outputs a predefined channel to the receiver.

Claims

1. A video system, comprising:

a remote control;

a receiver controlled by the remote control for receiving a plurality of video channels; and

a gateway controlled by the remote control for providing the video channels to the receiver, wherein the gateway has a power on state and a power off state, wherein the gateway in the power on state provides a video channel selected by a user of the system, and wherein the gateway in the power off state provides a predefined video channel to the receiver that is different than the user selected video channel.

2. The system of claim 1, wherein:

the remote control has a power control input;

the receiver has a power on state and a power off state;

the receiver and the gateway may be toggled between the power on and power off states in response to activation of the power control input; and

the predefined video channel is provided by the gateway after the gateway is toggled from the power on state to the power off state in response to the activation of the power control input, so that if the receiver is toggled from the power off state to the power on state, content from the predefined video channel may be provided to the receiver for display to the user.

3. The system of claim 1, wherein the predefined channel comprises vertical blanking interval (VBI) information.

4. The system of claim 1, wherein the gateway includes a timer operative to turn the gateway to an on state for a predetermined period of time.

5. The system of claim 1, wherein the predefined channel comprises emergency alert system (EAS) information.

6. The system of claim 1, wherein the predefined channel comprises channel content information.

7. The system of claim 1, wherein the gateway receives video signals from a video network, and wherein the gateway comprises MPEG decode circuitry to decode the signals received from the network into a predefined video format for the predefined video channel.

8. The system of claim 1, wherein the gateway comprises at least one gateway source, each gateway source receiving control signals from at least one remote control.

9. The system of claim 1, wherein the power control input is a button, the remote control transmitting a control signal indicating activation of the power control input each time the button is asserted.

10. The system of claim 1, wherein the gateway receives video signals from a video distribution line, and wherein the predefined channel requires less bandwidth than a standard video channel, whereby the bandwidth of signals carried over the distribution line is reduced when the gateway is in the off state.

11. A video gateway for providing video channels from a video network to a video receiver, the gateway toggled between an on condition and an off condition in response to power selection by a user, the gateway comprising:

a control program operated in response to power selection, wherein the program provides a video channel from the gateway to the video receiver that is selected by a user of the gateway when the gateway is in the on condition, and wherein the control program switches from the user selected video channel to predefined content other than the user selected channel after the gateway is toggled from the on condition to the off condition.

12. The gateway of claim 11, wherein:

the gateway and video receiver are both toggled between an on condition and an off condition in response to power selection by a user; and

wherein the predefined content is provided by the gateway after the gateway is toggled from the on condition to the off condition in response to power selection, so that if the receiver is toggled from the off condition to the on condition, the predefined content is provided to the receiver for display.

13. The gateway of claim 11, wherein power selection is made at a user operated remote control device having a power control input, wherein the receiver and the gateway are toggled between the on and off conditions in response to activation of the power control input, and wherein the predefined content is from a predefined video channel provided by the video network.

14. The system of claim 13, wherein the predefined channel comprises vertical blanking interval (VBI) information.

15. The system of claim 13, wherein the gateway includes a timer operative to turn the gateway to an on state for a predetermined period of time.

16. The system of claim 13, wherein the predefined channel comprises emergency alert system (EAS) information.

17. The system of claim 13, wherein the predefined channel comprises channel content information.

18. The system of claim 13, wherein the gateway receives video signals from a video network, and wherein the gateway further comprises MPEG decode circuitry to decode the signals received from the network into a predefined video format for the predefined video channel.

19. A method for power synchronization between a video receiver and a gateway that are controlled by a user operated control device, wherein the gateway provides video signals to the receiver representing a plurality of video channels, wherein each of the video receiver and the gateway have an on state and an off state, and wherein the gateway provides a video channel selected by a user when the gateway is in the on state, the method comprising:

providing a control signal from the control device to toggle the gateway between the on state to the off state; and

providing a predefined channel from the gateway to the receiver that is different than the user selected video channel, after the gateway is toggled from the on state to the off state.

20. The method of claim 19, wherein:

the control signal from the control device also toggles the receiver between the on state to the off state; and

the predefined channel is provided from the gateway to the receiver so that if the receiver is toggled from the off state to the on state, content from the predefined channel is provided to the receiver for display.

21. The method of claim 19, wherein the control device has a power control input, the method further comprising:

toggling the receiver and the gateway between the on and off states in response to activation of the power control input.

22. The method of claim 19, further comprising extracting vertical blanking interval (VBI) information from the predefined channel.

23. The method of claim 19, further comprising turning the gateway to an on state for a predetermined period of time at regular intervals.

24. The method of claim 19, further comprising extracting emergency alert system (EAS) information from the predefined channel.

25. The method of claim 19, wherein the gateway decodes a plurality of channels, the method further comprising extracting content information about the plurality of channels from the predefined channel.

26. The method of claim 19, wherein the decoding comprises MPEG decoding.

27. The method of claim 19, wherein the control device is a remote control.
