Claims34
A computer readable medium for storing a data structure, wherein said data structure comprises:
- a picture header;
- and
- at least one command following the picture header.
A decoder system for decoding video data, said decoder system comprising:
- a controller for writing commands into a picture data structure.
A method for displaying encrypted video data, said method comprising:
- decrypting a first encrypted data structure comprising a plurality of pictures, thereby recovering the first data structure;
- decoding at least some of the pictures of the plurality of pictures from the first data structure;
- and
- decrypting a second encrypted data structure comprising a plurality of pictures while decoding at least some pictures of the plurality of pictures from the first encrypted data structure.
A system for displaying encrypted video data, said system comprising:
- a decryption engine for decrypting a first encrypted data structure comprising a plurality of pictures, thereby recovering the first data structure;
- a video decoder for decoding at least some of the pictures of the plurality of pictures from the first data structure;
- and
- wherein the decryption engine decrypts a second encrypted data structure comprising a plurality of pictures while the video decoder decodes at least some pictures of the plurality of pictures from the first encrypted data structure.
