Abstract

A multimedia delivery platform includes a platform manager configured to monitor status of platform resources including content acquisition resources and a managed element, visible to the platform manager, including an externally accessible contact closure. A state of the contact closure is specified by user input provided by a platform manager user. The platform includes a shaking device configured to shake a signal acquisition device such as a dish antenna. A power relay in the platform includes a control terminal coupled to the contact closure of the managed element and output terminals configured to deliver power to the shaking machine upon activation of the power relay.

Claims

1. A content acquisition resource in a multimedia content delivery platform, the content acquisition resource comprising:

a shaking machine configured to shake an environmentally exposed signal acquisition device; and

a remotely controlled power relay configured to couple a power signal to the shaking machine responsive to assertion of a power control signal indicative of a user input from a remotely located user.

2. The content acquisition resource of claim 1, wherein the remotely controlled power relay comprises a solid state relay.

3. The content acquisition resource of claim 2, wherein the solid state relay comprises:

a triac including;

a gate terminal configured to receive an activation current responsive to assertion of the power control signal; and

first and second output terminals configured to establish an AC-compatible current path responsive to the gate terminal receiving the activation current.

4. The content acquisition resource of claim 3, wherein the solid state relay further includes:

an opto-isolator including;

a light emitting diode (LED) configured to generate light energy responsive to receiving the power control signal; and

an optically activated AC diode (diac) in proximity to the light emitting diode, configured to provide the activation current to the triac in response to receiving light energy from the LED.

5. The content acquisition resource of claim 1, wherein the power control signal comprises an output of a DC power supply, wherein a ground terminal of the DC supply is connected to a contact closure of a managed element of a platform management system.

6. The content acquisition resource of claim 1, wherein the signal acquisition device comprise a dish antenna.

7. A platform management system for a multimedia delivery platform, the system comprising:

a platform manager configured to monitor status of multimedia delivery platform resources including signal acquisition resources;

a managed element, accessible via the platform manager, including an externally accessible contact closure controllable via input from a user of the platform manager; and

a solid state relay including a control terminal coupled to the contact closure of the manager element and output terminals configured to output a power signal responsive to the control terminal receiving an activation current.

8. The platform management system of claim 7, further comprising a shaking device configured to shake a signal acquisition device, wherein supply inputs of the shaking device are connected to the solid state relay output terminals.

9. The platform management system of claim 8, further comprising a direct current (DC) power supply coupled between the contact closure and the control terminal of the solid state relay, wherein the contact closure is configured to provide a ground potential to a ground terminal of the DC power supply responsive to the user input.

10. The platform management system of claim 9, wherein the solid state relay includes an opto-isolator and wherein the DC power supply is configured to provide a DC current to the opto-isolator responsive to the user input.

11. The platform management system of claim 10, further comprising a web server configured to provide a user interface to a browser associated with the user for providing the user input.

12. A multimedia delivery platform comprising:

a platform manager configured to monitor status of platform resources including content acquisition resources;

a managed element visible to the platform manager, including an externally accessible contact closure wherein a state of the contact closure is specified by user input provided by a platform manager user;

a shaking device configured to shake a signal acquisition device; and

a power relay including a control terminal coupled to the contact closure of the managed element, wherein output terminals of the power relay deliver power to a shaking device responsive to activation of the power relay.

13. The multimedia delivery platform of claim 12, further comprising the signal acquisition device.

14. The multimedia delivery platform of claim 13, wherein the signal acquisition device comprises a dish antenna.

15. The multimedia delivery platform of claim 13, further comprising control logic configured to assert an on/off signal for the signal acquisition device in accordance with meteorological information received via environmental sensors, wherein the shaking machine is configured to shake the signal acquisition device when the on/off signal is asserted and the power relay is activated.

16. The multimedia delivery platform of claim 15, wherein the meteorological information includes temperature information received from a temperature sensor and precipitation information received from a precipitation sensor.

17. The multimedia delivery platform of claim 16, wherein the control logic is configured assert the on/off signal in further accordance with time-date information including information selected from:

time of day information, day of week information, and day of year information.

18. The multimedia delivery platform of claim 12, further comprising a DC power circuit configured to provide a DC current to the power relay control terminal responsive to closure of the contact closure.

19. The multimedia delivery platform of claim 12, wherein the power relay comprises a solid state relay including an opto-isolator configured to activate a triac responsive to assertion of the contact closure and wherein the triac is configured to couple a power signal to the shaking machine responsive to activation of the triac by the opto-isolator.

20. The multimedia delivery platform of claim 12, further comprising:

a processor; and

a computer readable storage device, wherein the platform manager includes processor executable program instructions, executable by the multimedia delivery platform.
