Stream synchronization using an automated digital clapperboard

An information handling system comprising:

• one or more processors;
• a memory coupled to at least one of the processors;
• a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions of:
• receiving, at a receiving device, a media stream comprising a metadata header, an audio stream and a video stream;
• extracting, from the metadata header, synchronization information comprising a set of audio tone values corresponding to a set of inaudible audio tones, a set of color values corresponding to a set of colors, and a set of pixel location values corresponding to a set of pixel locations, wherein the audio stream comprises the set of inaudible audio tones inserted at a set of predetermined frame intervals, and wherein the video stream comprises the set of colors inserted at the set of pixel locations at the predetermined frame intervals;
• in response to extracting the synchronization information, determining that a selected audio frame in the audio stream at which the set of inaudible audio tones corresponding to the extracted set of audio tone values are inserted is misaligned in time with a selected video frame in the video stream at which the set of colors corresponding to the extracted set of color values are inserted at the set of pixel locations corresponding to the extracted set of pixel location values;
• and
• synchronizing the audio stream with the video stream at one of the set of predetermined frame intervals in response to the determination.

A computer program product stored in a computer readable storage medium, comprising computer program code that, when executed by an information handling system, causes the information handling system to perform actions comprising:

• receiving, at a receiving device, a media stream comprising a metadata header, an audio stream and a video stream;
• extracting, from the metadata header, synchronization information comprising a set of audio tone values corresponding to a set of inaudible audio tones, a set of color values corresponding to a set of colors, and a set of pixel location values corresponding to a set of pixel locations, wherein the audio stream comprises the set of inaudible audio tones inserted at a set of predetermined frame intervals, and wherein the video stream comprises the set of colors inserted at the set of pixel locations at the predetermined frame intervals;
• in response to extracting the synchronization information, determining that a selected audio frame in the audio stream at which the set of inaudible audio tones corresponding to the extracted set of audio tone values are inserted is misaligned in time with a selected video frame in the video stream at which the set of colors corresponding to the extracted set of color values are inserted at the set of pixel locations corresponding to the extracted set of pixel location values;
• and
• synchronizing the audio stream with the video stream at one of the set of predetermined frame intervals in response to the determination.
