Abstract
The present invention is a system, method, and computer readable medium for inserting additional data into a digital audio/visual data stream, at points other than pre-defined splice points in the data stream. The inserted data may possess one or more attributes which differ from the original data stream. The distributor of an audio/video asset provides control information, including an insert file, which contains a list of insert points in the data stream. Reinitialization data information is also provided for each insert point. The reinitialization data includes the attribute information needed to reinitialize a decoder with the attributes of the original data stream after the inserted data is played. The original audio/video data stream is played until an insert point is reached. The additional data is then played. Next, the reinitialization data for the insert point is played in order to reinitialize the decoder with the attributes of the original data stream. Finally, the original audio/video data stream is restarted at the insert point. Decoder attributes are thus reset appropriately in order to play the original data stream after the additional data has been played.
