Adaptive power configuration for a MHL and HDMI combination multimedia device

1. A streaming apparatus comprising:

circuitry accommodated in a High-Definition Multimedia Interface (HDMI) connectable device, the circuitry configured to

detect a connection state of a Universal Serial Bus (USB) port of the streaming apparatus;

set an operational mode to a HDMI mode or a Mobile High Definition Link (MHL) mode based on the connection state of the USB port of the streaming apparatus; and

cause the streaming apparatus to draw power from the USB port when the state of the USB port indicates that the USB port is connected to another USB port or an MHL port,

wherein the circuitry is further configured to set the operation mode to the HDMI mode when the USB port is detected by the circuitry to be connected to the other USB port.

2. The apparatus of claim 1 , wherein the circuitry is further configured to set the operational mode to the MHL mode when the state of the USB port indicates that the USB port is connected to the MHL port.

3. The apparatus of claim 1 , wherein the circuitry include a HDMI transmitter connector and is further configured to set the HDMI transmitter connector to one of the HDMI mode and the MHL mode based on the connection state of the USB port.

4. The apparatus of claim 1 , wherein the circuitry is further configured to reset the operational mode in response to the circuitry detecting a change in the connection state of the USB port of the streaming apparatus so as to suppress a power glitch when the streaming apparatus boots from a stable power supply.

5. The apparatus of claim 1 , wherein the circuitry includes power management circuitry configured to track power consumed to switch a regulator supply by counting on and off cycles of a pulse width modulation signal.

6. A method to provide an adaptive power configuration for a High-Definition Multimedia Interface (HDMI) connectable streaming apparatus, comprising:

detecting, with circuitry, a connection state of a Universal Serial Bus (USB) port of the streaming apparatus;

setting, with the circuitry, an operational mode to a HDMI mode or a Mobile High Definition Link (MHL) mode based on the connection state of the USB port of the streaming apparatus; and

selecting, with the circuitry, a supply causing the streaming apparatus to draw power from the USB port when the connection state of the USB port indicates that the USB port is connected to another USB port or an MHL port,

wherein the setting further comprises setting, with the circuitry, the operation mode to the HDMI mode when the USB port is connected to the other USB port.

7. The method of claim 6 , wherein the setting further comprises setting, with the circuitry, the operation mode to the MHL mode when the USB port is connected to the MHL port.

8. The method of claim 6 , further comprising setting a HDMI transmitter connector to one of the HDMI mode and the MHL mode based on the connection state of the USB port of the streaming apparatus.

9. The method of claim 8 , further comprising resetting the operational mode in response to a change in the connection state of the USB port of the streaming apparatus so as to suppress a glitch when the streaming apparatus boots from a stable power supply.

10. The method of claim 6 , further comprising:

charging, with the circuitry, a battery of the streaming apparatus when the connection state of the USB port indicates that the USB port is connected to the other USB port or the MHL port.

11. The method according to claim 10 , wherein the streaming apparatus continues to draw power from the battery while the battery is being charged.

12. A non-transitory computer-readable medium storing executable instructions, which when executed by a computer processor, cause the computer processor to execute a method comprising:

detecting with the computer processor a connection state of a Universal Serial Bus (USB) port of the streaming apparatus;

setting with the computer processor an operational mode to a HDMI mode or a Mobile High Definition Link (MHL) mode based on the connection state of the USB port of the streaming apparatus; and

selecting a supply causing the streaming apparatus to draw power from the USB port when the connection state of the USB port indicates that the USB port is connected to another USB port or an MHL port,

wherein the setting further comprises setting, with the circuitry, the operation mode to the HDMI mode when the USB port is connected to the other USB port.

13. A streaming apparatus comprising:

circuitry accommodated in a High-Definition Multimedia Interface (HDMI) connectable device, the circuitry configured to

detect a connection state of a Universal Serial Bus (USB) port of the streaming apparatus;

set an operational mode to a HDMI mode or a Mobile High Definition Link (MHL) mode based on the connection state of the USB port of the streaming apparatus; and

cause the streaming apparatus to draw power from the USB port when the state of the USB port indicates that the USB port is connected to another USB port or an MHL port, and

a battery configured to power the streaming apparatus,

wherein the circuitry charges the battery with power drawn from the USB port when the connection state of the USB port indicates that the USB port is connected to the other USB port or the MHL port, and

wherein the circuitry sets the operation mode to the HDMI mode when the USB port is connected to the other USB port.

14. The apparatus of claim 13 , wherein the streaming apparatus continues to draw power from the battery while the circuitry charges the battery.
