Systems and methods for displaying subjects of an audio portion of content and displaying autocomplete suggestions for a search related to a subject of the audio portion
Systems and methods are described herein for displaying subjects of a portion of content and searching for content related to a particular subject in the content. Media data of content is analyzed during playback, and a number of action signatures are identified. Each action signature is associated with a particular subject within the content. The action signature is stored, along with a timestamp corresponding to a playback position at which the action signature begins, in association with an identifier of the particular subject. Upon receiving a command, icons representing each of a number of action signatures at or near the current playback position are displayed. Upon receiving user selection of an icon corresponding to a particular signature, a portion of the content corresponding to the action signature is played back or a search interface is displayed including autocomplete suggestions related to the subject of the signature.
1 . A method for searching content items, the method comprising:
identifying, during play of a content item, a plurality of audio signatures, each audio signature corresponding to respective audio data of a plurality of audio data in the content item;
storing, for each audio signature, a timestamp at which the respective audio data corresponding to the respective audio signature begins, and an identifier of a subject associated with the respective audio signature;
receiving an input command at a first portion of the content item;
generating for display at least an icon representing the identifier of the subject associated with the respective audio signature;
receiving a selection of the icon;
returning to a second portion of the content item according to the timestamp corresponding to a most recent audio signature associated with the subject represented by the icon selected; and
playing the second portion of the content item.
2 . The method of claim 1 , wherein determining an identifier of the subject of the audio signature represented by the selected icon comprises:
accessing metadata of the content item currently being played back; and
retrieving, from the metadata, based on the timestamp of the audio signature, the identifier of the subject of the audio signature.
3 . The method of claim 1 , further comprising:
retrieving a plurality of search strings;
transmitting a query to a database, the query comprising the identifier of the subject; and
receiving, in response to the query, the plurality of search strings.
4 . The method of claim 3 , wherein the database includes common search strings, and wherein the plurality of search strings comprises the most common search strings containing the identifier of the subject.
5 . The method of claim 3 , wherein the database includes popularity data and metadata describing content items, and wherein each search string of the plurality of search strings corresponds to a content item.
6 . The method of claim 3 , further comprising:
generating a search interface displaying an overlay over the content item currently being played back.
7 . The method of claim 1 , wherein the selection of the icon comprises a swipe gesture on a touchscreen interface.
8 . The method of claim 1 , wherein the selection of the icon comprises a tap on a touchscreen interface.
9 . A system for searching for content items, the system comprising:
memory; and
control circuitry configured to:
identify, during play of the content item, a plurality of audio signatures, each audio signature corresponding to respective audio data of a plurality of audio data in the content;
store, in the memory, for each audio signature, a timestamp at which the respective audio data corresponding to the respective audio signature begins, and an identifier of a subject associated with the respective audio signature;
receive an input command at a first portion of the content item;
generate for display at least an icon representing the identifier of the subject associated with the respective audio signature;
receive a selection of the icon;
return to a second portion of the content item according to the timestamp corresponding to a most recent audio signature associated with the subject represented by the icon selected; and
play the second portion of the content item.
10 . The system of claim 9 , wherein the control circuitry configured to determine an identifier of the subject of the audio signature represented by the selected icon is further configured to:
access metadata of the content item currently being played back; and
retrieve, from the metadata, based on the timestamp of the audio signature, the identifier of the subject of the audio signature.
11 . The system of claim 9 , wherein the control circuitry is configured to retrieve a plurality of search strings;
transmit a query to a database, the query comprising the identifier of the subject; and
receive, in response to the query, the plurality of search strings.
12 . The system of claim 11 , wherein the database includes common search strings, and wherein the plurality of search strings comprises the most common search strings containing the identifier of the subject.
13 . The system of claim 11 , wherein the database includes popularity data and metadata describing content items, and wherein each search string of the plurality of search strings corresponds to a content item.
14 . The system of claim 11 , wherein the control circuitry is configured to generate a search interface displaying an overlay over the content item currently being played back.
15 . The system of claim 9 , wherein the selection of the icon comprises a swipe gesture on a touchscreen interface.
16 . The system of claim 9 , wherein the selection of the icon comprises a tap on a touchscreen interface.
