Voice-controlled multimedia device
A computer-implemented method includes receiving, at a microphone of a voice-controlled device, a speech input from a user and determining, by the voice-controlled device, that a power state of an AV display device that is coupled to the voice-controlled device is an ON or OFF state. Based on the user intent determined from the speech input and the power state of the AV display, the voice-controlled device sends data to the AV display device to switch the AV display device ON or OFF. The method can further include receiving, by the voice-controlled device, content from a content source location and sending the content to the AV display device via an AV port.
1. A computer-implemented method, comprising:
receiving, at a microphone of a voice-controlled device having an internal speaker, a first speech input from a user, wherein the voice-controlled device is operatively connected to a first audio video (AV) input port of an AV display device, the first speech input including a wakeword;
determining, by the voice-controlled device, that a power state of the AV display device indicates that the AV display device is an ON state;
determining, by the voice-controlled device, an active AV input port of the AV display device to be an AV input other than the first AV input port;
sending data from the voice-controlled device to the AV display device to mute the AV display device;
receiving, at the microphone of the voice-controlled device, a second speech input, the second speech input including a user command to play content;
sending, by the voice-controlled device, data associated with at least the user command and the power state to a remote server computer;
receiving, by the voice-controlled device, response data from the remote server computer, wherein the response data comprises:
an indication that requested content includes video content;
instructions to set the active AV input port of the AV display device to the first AV port; and
a content source location identifier indicating a content source location for the video content;
based on the instructions to set the active AV input port of the AV display device to the first AV port, sending data from the voice-controlled device to the AV display device to set the active AV input port of the AV display device to the first AV port; and
sending data from the voice-controlled device to the AV display device to unmute the AV display device.
2. The computer-implemented method of claim 1 , further comprising:
receiving, by the voice-controlled device, content from the content source location; and
sending the content to the AV display device via the first AV port.
3. The computer-implemented method of claim 1 , wherein sending data from the voice-controlled device to the AV display device to set the active AV input port of the AV display device to the first AV port comprises sending an IR signal from the voice-controlled device to an IR receiver that is operably connected to the AV display device.
4. The computer-implemented method of claim 1 , wherein sending data from the voice-controlled device to the AV display device to set the active AV input port of the AV display device to the first AV port comprises sending HDMI data over an HDMI connection between the voice-controlled device and the AV display device.
5. The computer-implemented method of claim 1 , further comprising:
after receiving the indication that requested content includes video content, playing a handover audio message on the internal speaker of the voice-controlled device, wherein the handover audio message indicates to the user that the video content is going to be played on the AV display device.
6. The computer-implemented method of claim 1 , wherein sending data to mute and unmute the AV display device include sending an IR signal from the voice-controlled device to an IR receiver that is operably connected to the AV display device.
7. The computer-implemented method of claim 1 , wherein the first AV port is an HDMI port and wherein sending data to mute and unmute the AV display device include sending HDMI data to the first AV port.
8. The computer-implemented method of claim 1 , wherein the first AV port comprises an HDMI port.
9. The computer-implemented method of claim 1 , wherein determining that the power state of the AV display device indicates that the AV display device is an ON state comprises:
generating, by the voice-controlled device and in response to receiving the first speech input from the user, an electrical signal representing a pseudo-random number sequence;
transmitting the electrical signal to the first AV port of the AV display device; and
detecting, by the microphone of the voice-controlled device, a microphone signal that includes ambient room noise and a pseudo-random audio signal generated by the AV display device based on the electrical signal.
10. The computer-implemented method of claim 1 , wherein determining that the power state of the AV display device indicates that the AV display device is an ON state comprises:
detecting, by the voice-controlled device, a first voltage value of a hot plug detect (HPD) signal from the first AV port of the AV display device; and
detecting, by the voice-controlled device, data associated with a High Bandwidth Digital Content Protection (HDCP) signal from the first AV port of the AV display device.
