Abstract
The various implementations described herein describe using an audio stream to identify metadata associated with a currently playing television program. In one aspect, a method is performed at a computing device having processors and memory storing programs to be executed by the processors. The computing device obtains audio description data of a video stream for a media program. The audio description data comprises a synchronized audio narrative describing what is happening visually in the media program. The computing device identifies a set of information items including one or more words in the audio description data. The computing device transmits the words to a server. After the transmitting, the computing device obtains from the server information of content files related to the words. In response to obtaining the information, the computing device causes the information to be displayed on an electronic device that is distinct from the computing device.
