System for providing secondary content relating to a VoIp audio session

摘要

This disclosure describes embodiments of systems and methods that use protocols and techniques that can stream audio from a video device to a separate device while reducing or eliminate audio/video synchronization errors. In some embodiments, these systems and methods use Voice over IP (VoIP) technology to stream audio to mobile devices with low latency, resulting in little or no user-perceivable delay between the audio stream and corresponding video presentation. As a result, users can enjoy both the audio and video of any video display in an establishment. In addition, the systems and methods described herein may be implemented in the home or other locations to allow viewers who may be hard of hearing to listen to audio clearly via headphones.

主权项

1. A method of streaming an audio feed and secondary content to a user device, the method comprising:
by a content server comprising physical computer hardware:
receiving a request from a user device to access an audio feed for streaming, the audio feed associated with a corresponding video;wirelessly streaming the audio feed to the user device via a Voice over IP (VoIP) conference call;identifying a feed characteristic related to caption text associated with the video corresponding to the audio feed;extracting a plurality of keywords from the caption text;sorting the keywords based on frequency of occurrence in the caption text;selecting a most highly-ranked subset of the keywords based on the frequency of occurrence in the caption text;supplying the subset of the keywords to an ad server along with a request for an advertisement based on the subset of the keywords;receiving the advertisement in response to the request; andtransmitting the advertisement to the user device in response to receiving the advertisement, thereby providing a targeted advertisement related to the audio feed to the user device.
