Abstract
A system and method embed an audio signature in a video frame. An audio signature is generated from one bit a buffer input data. Two registers store an audio signature and reference count. According to an embodiment, the audio signature is generated left/right (L/R) interleaved with the left channel data in the most significant bit (MSB).
Claims15
A method for interlinking audio data and video data for synchronization by audio content comprising:
- forming an audio fingerprint by taking a bit sequence from an audio data;
- creating an audio signature by combining the audio fingerprint with a reference count that keeps a running count of all audio samples;
- embedding the audio signature in a video data, wherein the video data corresponds to the audio data.
A system for encoding an audio fingerprint comprising:
- a fingerprint register for receiving a bit sequence selected from an audio data;
- a signature generator for embedding the bit sequence in the fingerprint register in a video data, the video data corresponding to the audio data;
- and
- a reference count register for storing a reference count, wherein the reference count is a running count of all audio samples, wherein the signature generator embeds the reference count in the video data.
