In a computer environment, a new storage and delivery data format for multimedia object sets increases performance and improves the user experience by reducing the transactions needed to retrieve a set of n objects from n to 1. The object data is interleaved with data definition entries identifying respective object data into a data format comprising a single stream for storage and/or delivery. The data format eliminates the need for multiple, asynchronous transactions thus reducing latency in the data transfer process. Moreover, the data format allows for optimization of how the object data is prioritized and interleaved to achieve desired performance objectives upon delivery of the multimedia objects.
