摘要： A method of encrypting a transmission unit of a generalized scalable bit-stream includes, for each atom of the transmission unit, concatenating bit-stream segments that map to the atom to obtain data for each atom. The data for a logically first atom of the plurality of atoms of the multi-dimensional scalable representation is encrypted using an initialization input to produce an encryption output seed of the logically first atom and an encrypted logically first atom. In addition, the data of other atoms are encrypted to produce encrypted other atoms and an encryption output seed of each encrypted other atom. Encryption of a particular atom of the other atoms includes using encryption output seeds of adjacent causal atoms of the particular atom as an encryption input seed for encrypting the particular atom.

The system comprises an encoding module configured to encode multiple videos with a bitrate control strategy, a pair of complexity allocation control parameters and one or more target output video formats specifications, which include target resolution, target bitrate and target quality information. The encoding module obtains encoding bitrate, distortion and complexity performance samples from the encoding. From the encoding bitrate, distortion and complexity performance samples, the encoding module is configured to select optimal encoding bitrate, distortion and complexity performance samples.
