Ted Lin - Ayer MA, US

International Classification:

G10L 15/22
G06F 3/16
G10L 15/32

Abstract:

A first network microphone device (NMD) is configured to receive, from a second NMD, a first arbitration message including (i) a first measure of confidence associated with a voice input as detected by the second NMD and (ii) the voice input as detected by the second NMD, and receive, from a third NMD, a second arbitration message including (i) a second measure of confidence associated with the voice input as detected by the third NMD and (ii) the voice input as detected by the third NMD. The first NMD is configured to determine that the second measure of confidence is greater than the first measure of confidence and based on the determination, perform voice recognition based on the voice input as detected by the third NMD, where the voice input includes a command to control audio playback by the first, second, and/or third NMD, and after performing voice recognition, executing the command.

Abstract:

A control device of media playback system receives a user command to initiate playback of video content and associated audio content and transmits a BLUETOOTH message based on the command to a video playback device. The video playback device receives the BLUETOOTH message, obtains the media content via a local area network (LAN), and determines an indication of when to begin playback of the media content. The video playback device transmits the indication to an audio playback device via the LAN and outputs the video content in lip-synchrony with playback of the corresponding audio content by the audio playback device. While outputting the video content in lip-synchrony with playback of the corresponding audio content by the audio playback device, the video playback device transmits timing information via the LAN to the audio playback device to maintain lip-synchrony with playback of the corresponding audio content by the audio playback device.

Abstract:

A first zone player engages in synchronous playback of given audio content by obtaining the given audio content, generating and placing representative audio frames into a buffer, and transmitting the audio frames to a second zone player to play the given audio content in synchrony with the second zone player. After receiving a command to pause the synchronous playback, the first zone player prepares for a fast-resume by identifying a location in the given audio content and retaining some of the audio frames in the buffer for use during the fast-resume. The first zone player then initiates the fast-resume by determining a future resume time, transmitting an instruction to the second zone player to resume playback at the future resume time, and at the future resume time, resuming use of the audio frames in the buffer, starting at the identified location, to play the given audio content in synchrony.
