    • There is provided an AV server capable of internally establishing a logical connection and appropriately managing connection with a plurality of client devices even when a physical connection is firstly requested from a client device. The AV server includes a communication unit which communicates with the client device via a communication channel; a protocol processing unit which performs processes including retrieval of a UPnP AV-compliant device and capability exchange based on the logical connection; a content data accumulation unit which accumulates content data such as a recorded TV program, moving image data and still image data therein; a content data distribution unit which distributes the content data accumulated in the content data accumulation unit; and a connection management unit which manages HTTP connection session information based on the physical connection for distributing the content data.
    • 提供了即使当首先从客户端设备请求物理连接时,能够内部建立逻辑连接并适当地管理与多个客户端设备的连接的AV服务器。 AV服务器包括通信单元,其经由通信信道与客户端设备进行通信; 协议处理单元,其执行包括检索UPnP AV兼容设备和基于所述逻辑连接的能力交换的处理; 内容数据累积单元,其累积诸如所记录的TV节目,运动图像数据和静止图像数据的内容数据; 内容数据分发单元,其分配存储在所述内容数据累积单元中的内容数据; 以及连接管理单元,其基于用于分发内容数据的物理连接来管理HTTP连接会话信息。

    • In connection management by a conventional server apparatus using IDs, a client apparatus cannot know an attribute of a connection corresponding to an ID. A server apparatus (10) is an AV server apparatus that distributes content to a client apparatus requesting content data. A communication unit (11) receives a logical connection establishment request or a physical connection establishment request from the client apparatus. A content data distribution unit (14) establishes a physical connection for distributing the content data to the client apparatus, when the physical connection establishment request is received. A connection information management unit (15) establishes a logical connection, when the logical connection establishment request is received or as a result of the establishment of the physical connection. The connection information management unit (15) further generates an ID (connection ID) that corresponds to the logical connection and belongs to a value range associated with a logical connection category (type).
    • 在使用ID的常规服务器装置的连接管理中,客户端装置不能知道与ID对应的连接的属性。 服务器装置(10)是向内容数据的客户端装置分发内容的AV服务器装置。 通信单元(11)从客户端装置接收逻辑连接建立请求或物理连接建立请求。 当接收到物理连接建立请求时,内容数据分发单元(14)建立用于将内容数据分发给客户端装置的物理连接。 连接信息管理单元(15)在接收到逻辑连接建立请求时或建立物理连接的结果时建立逻辑连接。 连接信息管理单元(15)还生成与逻辑连接对应的ID(连接ID),属于与逻辑连接类型(类型)相关联的值范围。

    • The medium management device includes a communicating unit (11) that communicates with the client device (20); a content data accumulating unit (13) that accumulates content data transmitted to and received from the client device (20); a remaining capacity obtaining unit (15) that obtains remaining capacity indicating an amount of free space secured by the content data accumulating unit (13); and a protocol processing unit (12) that returns, to the client device (20), the remaining capacity that is secured by the file data accumulating unit (13) and obtained by the remaining capacity obtaining unit (15), when the server device receives a request for obtaining auxiliary information (browse request) from the client device (20), the request being related to the content and including a keyword made up of a specific character string.
    • 介质管理装置包括与客户端装置(20)进行通信的通信单元(11)。 内容数据累积单元(13),累积发送给客户端装置(20)并从其接收的内容数据; 剩余容量获取单元(15),其获得指示由所述内容数据存储单元(13)确保的空闲空间量的剩余容量; 以及协议处理单元(12),当所述服务器设备(12)向所述客户端设备(20)返回由所述文件数据存储单元(13)确保并由所述剩余容量获取单元(15)获得的剩余容量时, 接收从客户端装置(20)获取辅助信息(浏览请求)的请求,该请求与该内容相关,并包括由特定字符串组成的关键字。
