摘要： The described methodology provides users with the ability to specify flexible encryption options in a storage system using RAID technology. The users can use the system to achieve a configuration which achieves a desired balance between security and system load/performance. Specifically, one aspect of the methodology enables the user to enable or disable the encryption of the redundant parity information. Change of the data causes change of the parity information and, when parity is not encrypted, a close analysis of parity change may enable one to reconstruct the all or some of the encrypted data. Therefore, when a user chooses the encryption of the parity information, it becomes more difficult to reconstruct the plain data from the encrypted data. The described storage system also provides a function for monitoring and reporting the current or projected utilization of various computer resources including processor and memory utilization, which assists the user in selecting the proper security option.

摘要： In order to improve the accuracy of a code amount estimated by using a predictive residual when coding at a low data rate, an encoder is utilized to perform picture coding processing on a picture to be coded which is an input signal, by using a technique such as H.264. Specifically, a code amount predictor predicts the code amount on the basis of an evaluation value obtained by predictive-residual code amount evaluation value generating unit, a coding-condition code amount evaluation value generating unit, and a motion-vector-information code amount evaluation value generating unit. The predicted code amount is used for controlling coding in the encoder.

摘要： A picture coding device includes a motion prediction unit, an intra picture prediction unit, and an input selection unit. The input selection unit selects a smaller one of a motion total obtained by adding a motion residual and a value into which a motion vector is coded and an intra picture total obtained by adding an intra picture residual and a value into which a prediction mode is coded.
