A download assistant fetches a data stream from a remote location and processes the streamed data iteratively using buffers and multi-threaded processes through the decoder (e.g., codec), allowing source material-specific processing of the data as it is streamed from one or more download sources as well as content-indifferent and platform-indifferent decoding. To minimize versioning issues, payload construction for secure delivery is simplified to packing and encrypting a directory tree containing any number of files or other digital media into an archive and, when needed, dividing a payload into multiple files or archives with a descriptor that lists the archives. ## Claims ### Claim 1 A method comprising: receiving a request from a user device for executing selected content;
