Abstract: There are provided a transmitting section 308 for receiving program information representative of an outline and receiving condition of a receivable program and further receiving a program on the basis of the program information, and a zone-change determining section 307 for detecting a change of the program information. The program selecting section 309 causes the transmitting section 308 to suspend program reception and to switch a communication port, on the basis of a determination of a change of program distribution area by the zone-change determining section 307. Due to this, the transmitting section 308 is allowed to continuously receive the program so far received. This, in the case a program is provided at a communication port different based on each region, makes it possible to correctly receive a program even if moving traversing a region.

Abstract translation: 提供了一个发送部分308，用于接收表示可接收节目的概要和接收条件的节目信息，并且还基于节目信息接收节目;以及区域改变确定部分307，用于检测节目的变化 信息。 节目选择部309基于区域变更确定部307对节目分配区域的变化的判定，使发送部308暂停节目接收和切换通信端口。由此，发送部 308被允许连续接收到目前为止收到的程序。 这就是说，在基于每个区域的不同通信端口处提供程序的情况下，即使移动遍历一个区域，也可以正确地接收程序。

Abstract: The present invention generates watermark from ID information that uniquely identifies a program distribution destination, inserts the generated watermark in a program, and prevents the program from operating correctly if the watermark is tampered with, and also inserts the same watermark verification code in a program regardless of the distribution destination. By this means, it is possible to prevent detection of watermark verification code constituting a watermark by means of collusion attack.

Abstract: Provided is a content classifying section 203 for classifying and bundling to-be-transmitted contents on the basis of any piece of information of media kind, IP address, port number and session identifier. A packet header compressing section 204 carries out header compression on the transmission packet. Due to this, because contents can be packet-transferred with efficiency and excellent error resistance by the use of a communication and broadcast network, it is possible to realize, even on the Internet for broadcast in a broadcast form, a quality broadcast free of image or sound discontinuity as the terrestrial-wave TV broadcast.

Abstract translation: 提供了一种内容分类部分203，用于基于媒体类型，IP地址，端口号和会话标识符中的任何一条信息对待发送内容进行分类和捆绑。 分组首标压缩部分204对发送分组执行首标压缩。 由于这一点，因为通过使用通信和广播网络可以高效率和优异的差错抵抗性地传送内容，所以即使在以广播形式广播的因特网上，也可以实现无图像的质量广播 或声音不连续性作为地面波电视广播。
