A computer-implemented method includes receiving, at a microphone of a voice-controlled device, a speech input, generating an electrical signal having a first gain level that is below a gain threshold for audible detection by a user, transmitting the electrical signal to the speaker and detecting, by the microphone, an audio signal that includes a combination of ambient noise and a probe audio signal, wherein the probe audio signal is output by the speaker based on the electrical signal. The method further includes determining a power level of the probe audio signal and determining a state of the display based on the power level of the probe audio signal.

A multimedia service providing method according to an embodiment of the present invention may comprise: transmitting video data to a display device; transmitting a request message for requesting connection state information to one or more remote wireless speakers; receiving the connection state information from the one or more remote wireless speakers; separately calculating a delay time, which is a time at which a transmission delay is predicted, on the basis of the received connection state information; transmitting no audio data to a remote wireless speaker having a delay time longer than a preconfigured time from among the one or more remote wireless speakers; and transmitting the audio data to a remote wireless speaker having a delay time shorter than the preconfigured time from among the one or more remote wireless speakers, wherein the preconfigured time is configured to be a maximum allowable synchronization time difference between the video data and the audio data.

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for synchronizing playback of audio and video, wherein the audio is transmitted to wireless speakers over a wireless medium. Some embodiments operate by receiving content for playback from a source, wherein the content comprises the audio and the video; determining that synchronization of playback of the audio and video will not be acceptable, by analyzing the wireless medium to determine a probable transmission time it will take for the audio to be transmitted to the wireless speakers over the wireless medium; determining that a video buffer is not large enough to buffer the video long enough to compensate for the probable transmission time, based on at least a size of the video buffer and a resolution of the video; and requesting a lower resolution encoding of the video, wherein the requested video is of a resolution that can be buffered in the video buffer sufficiently long to compensate for the probable transmission time of the audio to the wireless speakers. Also, a lower quality encoding of the audio can be requested. Such lower quality audio will take less time to transmit to the wireless speakers so less buffering of the video will be needed to compensate for transmission delays of the audio.

An apparatus, method and system for connecting High-Definition Multimedia Interface (HDMI) devices. A loopback device connects between a first source device and a sink device on a first connection; a second source device connects to the sink device on a second connection. The loopback device manages the first connection, passes transition-minimized differential signaling (TMDS) or fixed-rate link (FRL) signals through to the sink device, and outputs audio received from the sink device on the audio return channel (ARC) or enhanced audio return channel (eARC). In this manner, audio that originates from any source device may be output without requiring a direct connection to the loopback device.

An analog/digital audio converting apparatus enables listening to both digital and analog audio signals received from a digital receiving apparatus and analog audio signals input from an external source using the same receiver by providing a formatter capable of converting the analog audio signal into a digital audio signal with the digital broadcasting receiving apparatus.

An audio adjustment system is provided that can output a user interface customized by the provider of the audio system instead of the electronic device manufacturer. Such an arrangement can save both field engineers and manufacturers a significant amount of time. Advantageously, in certain embodiments, such an audio adjustment system can be provided without knowledge of the electronic device's firmware. Instead, the audio adjustment system can communicate with the electronic device through an existing audio interface in the electronic device to enable a user to control audio enhancement parameters in the electronic device. For instance, the audio adjustment system can control the electronic device via an audio input jack on the electronic device.

An adapter provides a link between a digital media player having a memory on which is stored digital media files, a display device, and a remote control. The adapter receives from the digital media player data which is used to generate a representation of a user interface which is provided to the display device for display. The adapter also receives from the remote control data for use in generating commands for controlling operations of the digital media player whereby a change in state of the digital media player resulting from a performance of an operation caused by the remote control will be reflected in the user interface on the display device.

A wireless device may communicate, using short range communication in a low power mode, a poll to a sink device for display. The wireless device may communicate content to display on the sink device using a WiFi network and to communicate, by utilization of the WiFi network, a notification of an incoming call. Caller identification associated with the incoming call may be displayed on a display of the wireless device and a sink device.

A method of altering audio output from an electronic device based on image data is provided. In one embodiment, the method includes acquiring image data and determining one or more characteristics of the image data. Such characteristics may include sharpness, brightness, motion, magnification, zoom setting, and so forth, as well as variation in any of the preceding characteristics. The method may also include producing audio output, wherein at least one characteristic of the audio output is determined based on one or more of the image data characteristics. Various audio output characteristics that may be varied based on the video data characteristics may include, for instance, pitch, reverberation, tempo, volume, filter frequency response, added sound effects, or the like. Additional methods, devices, and manufactures are also disclosed.
