Patent ID: 8813137

Claim:
An apparatus in which encoded signals representing at least one image program and conveyed thereto in compressed and encrypted form on a storage medium are processed to enable display of the at least one image program, the apparatus comprising: a link configured to send and receive information external from the apparatus; a storage device configured to receive the storage medium; and a decoder configured to receive the compressed and encrypted encoded signals from the storage medium, the decoder comprising: a decryptor configured to decrypt the compressed and encrypted encoded signals to produce compressed encoded signals; a decompressor configured to: receive the compressed encoded signals from the decryptor and to decompress the compressed encoded signals to produce a plurality of data blocks to enable display of the at least one image program; and determine an error in one of the plurality of data blocks of the compressed and encrypted encoded signals from the storage medium; a theater manager configured to: request a replacement data block for the one of the plurality of data blocks with the determined error over the link, wherein the one of the plurality of data blocks with the determined error was not transmitted over the link; receive the replacement data block over the link; and store the replacement data block in a second storage medium that is separate from the storage medium; a playback module configured to play the at least one image program by accessing the plurality of data blocks of the compressed and encrypted encoded signals from the storage medium and accessing the replacement data block from the second storage medium.
