Abstract

A system and method operable to automatically disable input/output signal processing based on the required data format is provided. The need for an input/output module, such as an encoder, required to process input signal having a first data format (i.e. multimedia format) and produce an output signal having a second format (i.e. multimedia format) is determined. When the input/output module is not required to produce the output signal in the second format, the input/output module is disabled.

Claims (61)

1. A method comprises:

detecting whether an external device is coupled to an input/output (I/O) port of an integrated circuit (IC) device;

disabling an encoder of the IC device when no external device is coupled to the I/O port;

enabling the encoder to produce a multimedia output in a particular format associated with the external device when the external device is coupled to the I/O port;

temporarily disabling the encoder while detecting the external device coupled to the I/O port; and wherein the encoder comprises a video encoder.

2. The method of claim 1 , wherein the particular format comprises at least one of:

a digital video format;

a component video format;

an analog video format;

a composite video format;

digital audio format; and

an analog audio format.

3. The method of claim 1 , wherein the multimedia output comprises an analog video output.

4. The method of claim 1 , further comprising:

enabling a signal amplifier having an input coupled to an output of the encoder and an output coupled to the I/O port when the external device is coupled to the I/O port; and

disabling the signal amplifier when the external device is not coupled to the I/O port.

5. A method comprises:

detecting whether an external device is coupled to an input/output (I/O) port of an integrated circuit (IC) device;

disabling an encoder of the IC device when no external device is coupled to the I/O port;

enabling the encoder to receive and process a multimedia input in a particular format associated with the external device when the external device is coupled to the I/O port;

temporarily disabling the encoder while detecting whether any external device is coupled to the I/O port; and wherein the encoder comprises a video encoder.

6. The method of claim 5 , wherein the particular format comprises at least one of:

a digital video format;

a component video format;

an analog video format;

a composite video format;

a digital audio format; and

an analog audio format.

7. The method of claim 5 , further comprising:

temporarily disabling the encoder while detecting the external device coupled to the I/O port.

8. An integrated circuit (IC) device comprising:

an input/output (I/O) port;

an encoder coupled to the I/O port;

a detection module to detect whether an external device is coupled to the I/O port; and

a processing module to disable the encoder when no external, device is coupled to the I/O port and to enable the encoder when the external device is coupled to the I/O port,

the processing module further to temporarily disable the encoder while the detection module is detecting whether an external device is coupled to the I/O port; and wherein the encoder comprises a video encoder.

9. The IC device of claim 8 , further comprising:

a signal amplifier coupled between an output of the encoder and the I/O port; and

wherein the processing module further is to enable the signal amplifier when the external device is coupled to the I/O port and disable the signal amplifier when the external device is not coupled to the I/O port.

10. The IC device of claim 8 , wherein the particular format comprises at least one of:

a digital video format;

a component video format;

an analog video format;

a composite video format;

digital audio format; and

an analog audio format.

11. An integrated circuit (IC) device comprising:

an input/output (I/O) port;

an encoder coupled to the I/O port;

a detection module to detect whether an external device is coupled to the I/O port; and

a processing module to disable the encoder when no external device is coupled to the I/O port and to enable the encoder to receive and process a multimedia input in a particular format associated with the external device when the external device is coupled to the I/O port; wherein the processing module further is to, in response to a signal from the detection module temporarily disable the encoder while the detection module is detecting whether an external device is coupled to the I/O port; and wherein the encoder comprises a video encoder.

12. The IC device of claim 11 , further comprising:

a signal amplifier coupled between an output of the encoder and the I/O port; and

wherein the processing module further is to enable the signal amplifier when the external device is coupled to the I/O port and disable the signal amplifier when the external device is not coupled to the I/O port.

13. The IC device of claim 11 , wherein the particular format comprises at least one of:

a digital video format;

a component video format;

an analog video format;

a composite video format;

digital audio format; and

an analog audio format.
