Abstract

Apparatus, methods, and systems for centrally and uniformly controlling the operation of a variety of devices, such as communication, consumer electronic, audio-video, analog, digital, 1394, and the like, over a variety of protocols within a network system and, more particularly, a control system and uniform user interface for centrally controlling these devices in a manner that appears seamless and transparent to the user. In a preferred embodiment, a command center or hub of a network system includes a context and connection permutation sensitive control system that enables centralized and seamless integrated control of all types of input devices. The control system preferably includes a versatile icon based graphical user interface that provides a uniform, on-screen centralized control system for the network system. The user interface, which includes a visual recognition system, enables the user to transparently control multiple input devices over a variety of protocols while operating on a single control layer of an input command device. In an alternative embodiment, the control system also enables gated signal pass-through control while avoiding signal jamming.

Claims

1. A network system comprising

a plurality of input audio-video (AV) devices including a mix of a first set of devices comprising one or more devices controllable over a bidirectional digital bus and a second set of devices comprising one or more devices incapable of being controlled over the bidirectional digital bus, and

a television comprising a primary display and coupled to the plurality of input AV devices, the television comprising a control system being adapted to translate user input television specific commands to device specific output messages to directly drive the first set of input devices via signals communicated from the television over a bidirectional bus and drive the second set of devices via IR signals sent from the television to the second set of devices,

wherein the control system being adapted to generate a user interface (UI) displayable on the primary display screen, the UI including a device selection menu corresponding to the plurality of input devices, and

wherein the control system is adapted to direct an audio and/or video signal from a first source device of a plurality of input AV devices to the television via device specific output messages transmitted from the control system to the plurality of input AV devices and, in response to a user input television specific command, switch to directing a signal from a second source device of the plurality of input AV devices to the television, wherein the first and second source devices include one device selected from the first set of input AV devices and one selected from the second set of input AV devices.

2. The network of claim 1 wherein the television is a digital television.

3. The network of claim 1 further comprising a plurality of internal audio/video (AV) devices coupled to the circuit.

4. The network of claim 3 wherein the plurality of internal AV devices includes a source signal tuner.

5. The network of claim 1 wherein the control system comprises a user interface (UI) module adapted to translate user input TV specific commands.

6. The network of claim 5 wherein the control system further comprises first and second control modules coupled to the UI module, the control modules being adapted to convert translated user input TV specific commands into device specific output messages to drive the first and second set of AV input devices.

7. The network of claim 6 wherein the control system further comprises a television control module coupled to the UI module, the television control module adapted to convert translated user input TV specific commands into device specific messages to drive internal television AV input devices.

8. The network of claim 6 further comprising a driver module coupled to the second control module, the driver module adapted to communicate device appropriate output messages to the second set of AV input devices.

9. The network of claim 8 further comprising

an IR emitter controller coupled to the first control module, and

an IR emitter coupled to the emitter controller.

10. The network of claim 5 wherein the control system is adapted to generate a graphical user interface (GUI) displayable on the screen and coupled to the UI module.

11. The network of claim 10 wherein the device selection menu comprises a plurality of icons corresponding to a plurality of internal AV input devices and external AV input devices when such devices are coupled to the television outputs.

12. The network of claim 11 wherein the device selection menu comprises a device selection window, a video sink window, and an audio sink window.

13. The network of claim 12 wherein the device selection menu further comprises a connection sink window.

14. The network of claim 11 wherein the GUI further comprises a visual recognition system.

15. The network of claim 14 wherein the visual recognition system comprises three states of visual recognition.

16. The network of claim 15 wherein the three states of visual recognition comprise a disabled state, a current device state, and a selected icon state.

17. The network of claim 14 wherein the visual recognition system further comprises five states of visual recognition.

18. The network of claim 17 wherein the five states of visual recognition system comprise a disable state, a selected icon/current device state, a selected icon/not current device state, a not selected icon/not current device state, and a not selected icon/current device state.

19. The network of claim 6 wherein the UI module comprises:

a first module adapted to determine a current system state and whether an input command comprises a menu related action or a direct device action,

a second module coupled to the first module, the second module adapted to determine whether a menu related action is a menu display action, a menu navigate action or a menu device action, and

a third module coupled to the first and second modules, the third module adapted to determine what device connections to make and instructing the IR and 1394 control modules as to what device actions to take.
