摘要： A cellular phone has distributed encrypted content data and an encrypted content key stored in a memory. The encrypted content key data read out from the memory is decrypted by a decryption processing unit using key data Kp stored in a Kp hold unit, and then applied to a audio reproduction module. A decryption processing unit decrypts encrypted content data read out from the memory using a content key Kc extracted by the decryption processing unit to reproduce content data Dc.

摘要： A memory card (110) conducts an authentication process with a server based on data stored in an authentication data hold unit (1400). The memory card (110) extracts a first session key (Ks1) from a server by a decryption process and a transaction ID from the data applied on a data bus (BS3). The memory card (110) generates a second session key (Ks2) through a session key generation unit (1418), and transmits to the server, as the keys to encrypt content data in receiving decryption of content data, the second session key (Ks2) and a key (KPm(1)) unique to the memory card (110) in an encrypted state with the first session key (Ks1). The transaction ID and the second session key (Ks2) stored in the log memory (1460) are used in the redistribution process.

摘要： An image data compression method in which reductions in data amount are achieved by deleting some pixel data. Compression is achieved by performing a reading step to read an image as plural pixel data and a deleting step to delete some of the pixel data. A prediction error calculating step calculates a prediction error that represents the difference between the color value pixel data of a pixel in question and the predicted color value thereof, as predicted by a prescribed prediction method from the pixel data of a pixel adjacent thereto. An area classifying step classifies the pixel data of the entire image area into either an abrupt color change areas type in which the prediction error is large or a nonabrupt color change area in which the prediction error is small. The deleting step is performed only on the pixel data classified in the nonabrupt color change area; deleted-position information is appended to the non-deleted pixel data that indicates the position of a pixel whose data has been deleted. This improves the quality of reproduction, since no pixel data are deleted where large errors would be expected to occur in reproduction.
摘要翻译：一种通过删除一些像素数据来实现数据量减少的图像数据压缩方法。通过执行读取步骤以将图像读取为多个像素数据和删除步骤来删除一些像素数据来实现压缩。预测误差计算步骤，根据由与其相邻的像素的像素数据预测的规定的预测方法，计算表示所考虑的像素的色彩值像素数据与预测色彩值之间的差的预测误差。区域分类步骤将整个图像区域的像素数据分类为预测误差大的突变颜色变化区域类型或其中预测误差小的非中断颜色变化区域。删除步骤仅对分类在非破坏颜色变化区域中的像素数据执行; 删除位置信息被附加到指示其数据被删除的像素的位置的未删除的像素数据。这提高了再现的质量，因为没有像素数据被删除，在再现期间会发生大的错误。

摘要： A video data reproducing apparatus and method therefor having a file controller section for controlling video data recorded on a first recording medium at random positions, and further, having a second recording medium for recording the video data in a serial manner. The apparatus includes a decision section for judging whether to select the video data of either the first recording medium or the second recording medium. A first reading section reads out the data of the first recording medium through the file controller section when the first recording medium is selected by the decision section, and a second reading section reads out the video data to a buffer memory from the second recording medium, without any intervention of the file controller section, when the second recording medium is selected by the decision section.

摘要： Disclosed is an image processing system including an image input unit, an extraction unit, a plurality of compression process parts and a selection unit to compress a 1-frame image down to a less amount of color information. The image input unit takes in a plurality of frame images per frame. The extraction unit extracts each of the taken-in frame images per unit area of a designated size. The plurality of compression process parts effects compression processes different from each other with respect to pels contained in each unit area. The selection unit selects one compression process part from the plurality of compression process parts for compressing the unit area of the designated size.
