Mark Ely - Los Gatos CA, US
Brian Thoft Moth Møller - Hojbjerg, DK

Assignee:

Roku, Inc. - San Jose CA

International Classification:

H04B 1/7087
G06F 3/16
H04R 1/02
H04N 5/60
H04N 5/073

Abstract:

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 audiovisual content with a dumb speaker. In some embodiments, an electronic device transmits a spread spectrum signal to a dumb speaker over a data channel using a spread spectrum code. The electronic device then receives the spread spectrum signal played back auditorily by the dumb speaker. The electronic device despreads the spread spectrum signal based on the spreading code. The electronic device determines a time of receipt of the spread spectrum signal. The electronic device calculates an audiovisual output path delay for the dumb speaker based on the time of receipt and a time of transmission. The electronic device then synchronizes the playback of the audiovisual content at the dumb speaker and another electronic device based on the audiovisual output path delay.

International Classification:

H04B 1/7073
H04R 3/12
H04L 29/06

Abstract:

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for identifying electronic devices in a room using a spread code. In some embodiments, a first electronic device receives a spread spectrum signal from a second electronic device over an audio data channel. The first electronic device determines a time of receipt of the spread spectrum signal based on despreading. The first electronic device calculates a distance between the first electronic device and the second electronic device based on the time of receipt and a time of transmission. The first electronic device determines the second electronic device is not in the room with the first electronic device based on the calculated distance.

Roku, Inc. - Los Gatos CA

International Classification:

H04N 5/60

Abstract:

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 audiovisual content among multiple speakers. In some embodiments, a first smart speaker receives a spread spectrum signal from a second smart speaker over an audio data channel. The first smart speaker despreads the spread spectrum signal based on a spreading code. The first smart speaker determines a time of receipt of the spread spectrum signal based on the despreading. The first smart speaker receives a time of transmission of the spread spectrum signal. The first smart speaker then calculates a playback delay based on the time of receipt and the time of transmission. Then the first smart speaker controls the playback of the audiovisual content based on the playback delay.

Abstract:

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for identifying audio characteristics of a room using a spread code. In some embodiments, an audio responsive receives a spread spectrum signal from a smart speaker over an audio data channel. The audio responsive remote control determines a time of receipt of the spread spectrum signal based on despreading. The audio responsive remote control calculates an airtime delay associated with the smart speaker based on the time of receipt and a time of transmission. The audio responsive remote control then adjusts playback of audiovisual content at the smart speaker and a second smart speaker for a location based on the airtime delay. The audio responsive remote control can also determine whether the smart speaker is present in the room with it based on the airtime delay.

Abstract:

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 audiovisual content with a dumb speaker. In some embodiments, a display device transmits a spread spectrum signal to a dumb speaker over a data channel using a spread spectrum code. The display device then receives the spread spectrum signal from the dumb speaker over an audio data channel. The display device despreads the spread spectrum signal based on the spreading code. The display device determines a time of receipt of the spread spectrum signal. The display device calculates an audiovisual output path delay for the dumb speaker based on the time of receipt and a time of transmission. The display device then synchronizes the playback of the audiovisual content at the dumb speaker and a smart speaker based on the audiovisual output path delay.
