    • An image data transmitting apparatus and an image data transmitting method are provided which can distribute streaming moving images at a transfer rate in accordance with a transmission band with degradation in image quality being mitigated even at the time of congestion. A priority determining section 43 reads encoded data stored in the buffer 42 in units of VOP, and then calculates a priority for each VP in terms of VOP based on the amount of encoded data of VP and the number of MBs. A transmission control section 44 determines VPs starting from a VP of the highest priority that have a data amount up to the amount of transmittable encoded data. This determination is made based on the current state of congestion on a network 6 managed by a congestion state managing section 46 and the priorities calculated by the priority determining section 43. A VP transmitting section 45 stores the determined VPs in transmission packets for sequential transmission to a client 5.

    • The invention aims to protect content copyright and reduce the load on a stream server device in a stream distribution system having the stream server device, which stores bitstreams that include contents and control information necessary for image playback of contents, a plurality of terminal devices that playback received bitstreams, and a cache server device that mediates between these devices. A header separation unit in the stream server device separates header information, which is control information, from a bitstream stored in a storage unit. A data transmitting unit transmits the bitstream from which header information has been removed to the cache server device before a predetermined time, and transmits the header information to the cache server device at the predetermined time. The cache server device transmits a bitstream that combines the bitstream, which was received first, and the header information, which was received later, to a terminal device. The terminal device receives the bitstream at the predetermined time, and plays the content.

    • An image processing device for processing an original image divided into a plurality of blocks that are made up of a plurality of picture elements from encoded image-data which is obtained by encoding a spatial-frequency component of the block as a plurality of spatial-frequency coefficients, and producing reduced encoded image-data which is encoded data on a reduced image that is obtained by reducing the original image to a given reduction rate. If the block in the encoded image-data of the original image is in an area where the value of the function is small due to gentle change in brightness or color of the image, for example, only the direct-current component coefficient of is used for the block. On the other hand, if the block is in a area where the value of the function is large because the area is a boundary area, for example, such as an outline in the image, limited number of lower spatial frequency-coefficients are used for the block. The number is based on the reduction rate of the image.
    • 一种图像处理装置,用于处理由编码图像数据分割成由多个图像元素组成的多个块的原始图像,该图像数据是通过将该块的空间频率分量编码为多个空间频率 系数,并且产生缩小的编码图像数据,其是通过将原始图像减少到给定的缩小率而获得的缩小图像上的编码数据。 如果原始图像的编码图像数据中的块在由于图像的亮度或颜色的温和变化而在功能值较小的区域中,例如仅使用直流分量系数 为块。 另一方面,如果块位于功能值大的区域,因为该区域是边界区域,例如像图像中的轮廓,则使用较低空间频率系数的有限数量用于 块。 数字是基于图像的缩小率。

    • A resource management system is composed of a plurality of application programs, a resource management information database, and a resource manager. Each application program executes data transfer using resources. The resource management database stores resource management information and key information for each resource. Upon receipt of a resource use request from an application program, the resource manager judges whether the requested resource can be allocated to the application program by referring to the resource capacity and the currently-allocated volume of the resource that are included in the information database. If judging that the requested resource can be allocated, the resource manager gives authorization to the application program to use the resource. The resource manager also controls resource allocation by restricting a data transfer bandwidth used by an application program and requesting a resource release on expiration of the valid time period.
    • 资源管理系统由多个应用程序,资源管理信息数据库和资源管理器构成。 每个应用程序使用资源执行数据传输。 资源管理数据库存储每个资源的资源管理信息和密钥信息。 在从应用程序接收到资源使用请求时,资源管理器通过参考信息数据库中包括的资源的资源容量和当前分配的资源来判断所请求资源是否可以分配给应用程序。 如果判断可以分配所请求的资源,则资源管理器授予应用程序来使用该资源。 资源管理器还通过限制应用程序使用的数据传输带宽并在有效时间段到期时请求资源释放来控制资源分配。
