1. A system for distributing digital data, the system comprising:

  • a digital data processing device configured to add header information to a stream that includes digital data, process the stream to render the digital data unusable by an execution device, wherein rendering the digital data unusable by an execution device comprises at least one of blanking out and truncating the digital data, and distribute the stream, wherein the header information includes timestamp information, offset information, and source location information for the stream; and

    an execution device configured to receive the processed stream from the digital data processing device, wherein the processed stream includes the digital data rendered unusable by the digital data processing device, locate a source of the digital data other than the digital data processing device based on the source location information, seek an offset in the digital data based on the offset information, and retrieve the digital data at the offset from the source other than the digital data processing device.
