摘要： The invention relates to encryption and decryption of auxiliary data in the memory of a computer system. The encryption and decryption utilizes a data structure of the auxiliary data. The data structure comprises at least partially independent subunits. The auxiliary data is received into a processor unit and an encryption/decryption key associated to a subunit is provided. The encrypting/decryption of the auxiliary data is performed in a process where the encryption/decryption key is changed at boundaries between subunits, so that subunits of the auxiliary data is encrypted/decrypted using associated encryption keys. Embodiments of the invention are applicable in the field of memory encryption of audio¬ visual data (AV data).

摘要： A system (600) and method of processing encoded video data employs two decoders (610/620). A first decoder (610) decodes units of encoded video data of a current video frame of a compressed video signal according to an intra picture decoding format, and outputs a first output (615). A memory (630) stores one or more units of encoded video data from one or more previous video frames. A second video decoder (620) decodes units of the encoded video data from the memory (630), and outputs a second output (625). A multiplexer (640) selects between the first output (615) and the second output (625) based on control data indicating units in the current video frame that are reused from one or more preceding video frames, and outputs a decoded video signal (645).

摘要： A method and a system conceal errors in video data transmission. An encoded current bitstream is received from a demodulator at a first decoder, which decodes the current bitstream. An encoded previous bit stream is received from a memoryat a second decoder, which decodes the previous bitstream. When it is determined that the current bitstream does not include an error, the decoded current bitstream output from the first decoder is selected, and when it is determined that the current bitstream does include an error, the decoded previous bitstream output from the second decoder is selected. The second decoder may operate in parallel with the first decoder.

摘要： Devices, systems and methods are used in connection with a compressed video stream. According to one embodiment of the present invention, a device is implemented for decompressing a received compressed video stream that includes image slices. The image slices each include macro-blocks. The device has a memory for storing the compressed image slices and macro-blocks associated with the image slices. A first processing circuit decompresses the image slices stored in the memory. A second processing circuit decompresses image slices from the received compressed video stream. A third processing circuit generates a decompressed video stream from a combination of decompressed image slices from the first processing circuit and decompressed image slices from the second processing circuit.
