Program guide application interface system
View Patent ↗A program guide system is provided that supports a program guide application and multiple non-guide applications. The program guide system has a program guide application interface that allows the non-guide applications to use both device resources and program guide resources. The application interface maintains a list of registered applications and directs control requests from various applications to the current primary application. The application interface also has a user interface input director that directs keystrokes and other user input commands to the appropriate application. If a keystroke for the program guide application is detected while a non-guide application is running, the program guide application is invoked.

suspending operation of the application with primary control of the user equipment.
10. The method of claim 1 , wherein the control request is tagged with an identifier associated with the requesting application, and wherein transferring control of the user equipment to the requesting application comprises:
identifying the requesting application by comparing the identifier of the control request to a plurality of identifiers included in a registered application list.
11. The system of claim 1 , wherein the control request is tagged with an identifier associated with the requesting application, and wherein the control request processor is further configured to:
identify the requesting application by comparing the identifier of the control request to a plurality of identifiers included in a registered application list.
12. The method of claim 10 , wherein the registered application list comprises a communications address and an identifier for each registered application.
13. The system of claim 11 , wherein the registered application list comprises a communications address and an identifier for each registered application.
14. The method of claim 1 , wherein each of the plurality of applications has a unique function.
15. The method of claim 1 , wherein the user equipment includes a user television equipment.
16. The method of claim 1 , wherein the resource requirement comprises at least one of a database access resource, a graphics library resource, a parental control resource, a scheduling resource, and a tuning resource.
17. The method of claim 1 , wherein the resource requirement of the requesting application comprises a plurality of resources, and transferring control of the user equipment to the requesting application comprises:
transferring control of a subset of the plurality of resources to the requesting applications, wherein the subset of the plurality of resources is determined based on the resource requirement of the requesting application.
18. The method of claim 1 , wherein another one of the plurality of applications has primary control of the user equipment, and determining whether to transfer control of the user equipment to the requesting application comprises:
retrieving the resource requirement of the requesting application; and
comparing the resource requirement of the requesting application to the resource requirement of the other one of the plurality of applications.
19. A system for allowing a plurality of applications, each implemented on user equipment and associated with a resource requirement, to assume control of the user equipment, wherein one of the plurality of applications is an interactive program guide, the system comprising:
a control request processor configured to:
receive a control request from a requesting application, wherein the requesting application is one of the plurality of applications;
compare a first plurality of buttons associated with an active mode of the requesting application with a second plurality of buttons associated with an active mode of a second application of the plurality of applications;
determine, without user input, whether any button in the first plurality of buttons is included in the second plurality of buttons; and
transfer control of the user equipment to the requesting application in response to determining that none of the first plurality of buttons is included in the second plurality of buttons.
20. The system of claim 19 , wherein the control request processor is further configured to:
determine whether another one of the plurality of applications has primary control of the user equipment.
21. The system of claim 20 , wherein the control request processor is further configured to:
determine whether to transfer control of the user equipment from the application with primary control to the requesting application based on priorities associated with the requesting application and the application with primary control.
22. The system of claim 20 , wherein the control request processor is further configured to:
provide the control request to the application with primary control of the user equipment, wherein the application with primary control relinquishes control of the user equipment in response to receiving the control request.
