Abstract
The techniques described herein relate to methods, apparatus, and computer readable media configured to perform an asset change for video data. First video data comprises a sequence of data units separated by data unit boundaries, and a sequence of error correction data units, wherein each error correction data unit is associated with one or more data units from the sequence of data units. Based on the received first video data, it can be determined whether an error correction data unit from the sequence of error correction data units associated with an asset change point of the first video data crosses one or more data unit boundaries of the first video data. Based on the determination, an asset change operation for the first video data and second video data is performed, wherein the second video data is different than the first video data.
