Abstract
An alternative content system receives a primary content data stream and a secondary content data stream associated with an event. The alternative content system provides an alternative content data stream associated with the event. The alternative content system extracts a primary content identifier from the primary content data stream. The alternative content system identifies an alternative content identifier based on the alternative content data stream. The alternative content system synchronizes the alternative content data stream to the primary content data stream based on the alternative content identifier and the primary content identifier. The alternative content system transmits the synchronized alternative content data stream based on the primary content identifier.
