Synchronizing secondary audiovisual content based on frame transitions in streaming content

A computer-implemented method comprising:

• determining a set of frame transitions for a video, wherein each frame transition corresponds to a respective starting frame that is determined to be different from a prior frame based on the predefined frame reference function;
• capturing, by a secondary device and at a first time, a currently displayed first frame of the video during playback of the video by a primary device;
• determining, by the secondary device, a first playback position of the video based on a first frame transition, of the set of frame transitions, corresponding to the captured first frame of the video;
• synchronizing, by the secondary device, secondary audiovisual content with the playback of the video based on the first frame transition corresponding to the captured first frame of the video;
• capturing, by the secondary device and at a second time, a currently displayed second frame of the video during the playback of the video by the primary device;
• determining, by the secondary device, a second frame transition, of the set of frame transitions, corresponding to the captured second frame when the predefined frame reference function indicates that the captured second frame is different from the captured first frame;
• and
• synchronizing, by the secondary device and based on determining the second frame transition, the secondary audiovisual content with the playback of the video based on the starting frame of the second frame transition identified as corresponding to the captured second frame.

A computing device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the computing device to:
• determine a set of frame transition ranges for a video, wherein each respective frame transition range comprises a starting frame identifier and an ending frame identifier associated with a series of frames of the video that are each determined to be substantially identical by a predefined frame reference function;
• capture, at a first time, a currently displayed first frame of the video during playback of the video by a primary device;
• determine a first frame transition range corresponding to the captured first frame of the video;
• synchronizing secondary audiovisual content with the playback of the video based on the first frame transition range corresponding to the captured first frame of the video;
• capture, at a second time, a currently displayed second frame of the video during the playback of the video by the primary device;
• determine whether the captured second frame corresponds to a current frame transition range corresponding to a current playback position of the secondary audiovisual content based on the predefined frame reference function;
• and
• synchronize, based on determining that the captured second frame does not correspond to the current frame transition range, the secondary audiovisual content with the playback of the video based on a second frame transition range identified as corresponding to the captured second frame based on the predefined frame reference function.

A non-transitory computer-readable medium comprising instructions that, when executed by a computing device, cause the computing device to perform steps comprising:

• determining a set of frame transition ranges for a video, wherein each respective frame transition range comprises a starting frame identifier and an ending frame identifier associated with a series of frames of the video that are each determined to be substantially identical by a predefined frame reference function;
• capturing, at a first time, a currently displayed first frame of the video during playback of the video by a primary device;
• determining a first frame transition range corresponding to the captured first frame of the video;
• synchronizing secondary audiovisual content with the playback of the video based on the first frame transition range corresponding to the captured first frame of the video;
• capturing, at a second time, a currently displayed second frame of the video during the playback of the video by the primary device;
• determining whether the captured second frame corresponds to a current frame transition range corresponding to a current playback position of the secondary audiovisual content based on the predefined frame reference function;
• and
• synchronizing, based on determining that the captured second frame does not correspond to the current frame transition range, the secondary audiovisual content with the playback of the video based on a second frame transition range identified as corresponding to the captured second frame based on the predefined frame reference function.
