摘要： A motion picture coding and decoding system is provided, which permits high picture quality to be obtained with less information amount than that in case of a system having the sole function of DCT coding, permits reduction of block distortion of reproduced picture and permits coding efficiency increase. One picture frame is divided into a plurality of blocks for block-by-block coding. At this time, discrete cosine transform (DCT) coding and intra-block non-transform coding (NTC) are adaptively switched one over to the other according to the character of pattern. In case of the intra-block non-transform coding, predictive values of block and quantizing width are transmitted. Each block is adaptively selected with sub block of frame construction or sub block of field construction.

摘要： Video signal transmitting system in which digital video signal are divided into groups of predetermined frames. Digital video signals of at least one frame are intraframe coded and then transmitted. Remaining digital video signals are interframe coded with reference to the intraframe coded digital video signals, and intraframe coded digital video signals of a subsequent group of frames and are then transmitted. A motion vector from a predetermined reference frame is detected. Video signals are interframe coded by the motion vector to transmit the video signals. A motion vector from a first frame which is a plurality of frames away from the reference frame is converted to a motion vector for a one frame interval between the reference frame and the first frame. The motion vector is optimized, and is then transmitted.

摘要： A configuration is achieved in which content copying between media and content downloading are performed effectively and under strict management. In content copying between media, the identification information (medium ID) of a copying destination medium is obtained using an API for providing a predefined processing, then the obtained medium ID is transmitted to a server to obtain copying permission information from the server, and then content copying is performed under the management of the server. This configuration allows a copying destination medium to be managed, which can eliminate the unauthorized use of the content. Also, the configuration in which content downloading from the server is performed according to, for example, a Java® program allows a ROM disc on which the content is recorded to store the program and to be provided to a user.

摘要： The present technology relates to an encoding device, an encoding method, a decoding device, and a decoding method capable of suppressing the amount of information without degrading the image quality of an image of a viewpoint that is used when the compatibility is secured in a case where a multi-viewpoint image is encoded. A compatible encoder generates a compatible stream by encoding an image A1 that is a compatible image. An image converting unit lowers the resolution of images B1 and C1 that are auxiliary images. An auxiliary encoder generates an encoded stream of the auxiliary image by encoding the auxiliary image of which the resolution is lowered. A multiplexing unit transmits the compatible stream and the encoded stream of the auxiliary image. The present technology can be applied to, for example, an encoding device that encodes a 3D image of the multi-viewpoint mode.

摘要： A virtual machine can be implemented by anyone because the interface and other information necessary for implementation are publicly available. Therefore, it is possible that by implementing the virtual machine illegitimately, programs run thereon on will be made to operate illegitimately instead of legitimately. A program compares secret information held by the virtual machine with verification information held by the program itself. The program thereby verifies whether the virtual machine that runs the program is implemented legitimately, and is able to reject an illegitimate virtual machine.

摘要翻译： 虚拟机可以由任何人实现，因为实现所需的接口和其他信息是公开的。 因此，有可能通过非法实施虚拟机，在其上执行的程序将被非法地而非合法地运行。 程序将由虚拟机保存的秘密信息与由程序本身保存的验证信息进行比较。 该程序从而验证运行程序的虚拟机是否合法实现，并且能够拒绝非法虚拟机。

摘要： A transmitter which transmits video content via a predetermined network, wherein the video content is encoded while an image group containing a plurality of frame images is handled as a processing unit, the transmitter includes a formation unit and a transmission unit. The formation unit is configured to form invalid-image information for an image group containing at least an edit point of edited video content in order to indicate invalid frame images within the image group in accordance with edit point information about the edited video content. The transmission unit is configured to transmit video content via the predetermined network and, if there is invalid-image information formed by the formation unit, transmit the invalid-image information before transmitting the associated image group.
