Systems and Methods for Locally Detecting Consumed Video Content

摘要

A process provides a user with context-aware information. The process is performed at a client device with one or more processors, a microphone, and memory. The memory stores one or more programs configured for execution by the one or more processors. The process receives audio fingerprints for a plurality of video programs and information that correlates each respective received audio fingerprint to a respective video program, and stores the received audio fingerprints and correlating information in memory. The process detects ambient sound using the microphone, and computes one or more sample audio fingerprints from the detected ambient sound. The process matches one of the sample audio fingerprints to a first stored audio fingerprint and uses the correlating information to identify a first video program corresponding to the matched sample audio fingerprint. The process then provides the user with information related to the first video program.

1. A method of providing a user with context-aware information, comprising:
at a client device with one or more processors, a microphone, and memory storing one or more programs configured for execution by the one or more processors:
downloading audio fingerprints from a remote server for a plurality of video programs and information that correlates each respective received audio fingerprint to a respective video program;storing locally the received audio fingerprints and correlating information in the memory;detecting ambient sound using the microphone;computing one or more sample audio fingerprints from the detected ambient sound;matching one of the sample audio fingerprints to a first audio fingerprint of the locally stored audio fingerprints and using the correlating information to identify a first video program corresponding to the matched sample audio fingerprint; andin response to the matching, providing the user with information related to the first video program.
