Abstract: In the present invention, content is comprised of a plurality of items of data (1101, 1102, 1103, 1104), and a transmission cycle and others of data composing the content are varied corresponding to the importance and/or necessity and purpose of the data. In this way, for example, it is possible to set a shorter transmission cycle on high-necessity data than the transmission cycle of the low-necessity data, and to set a shorter transmission cycle on information such as summary information requiring fast viewing than the transmission cycle of detailed information.

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。

Abstract: In the present invention, with respect to content that is predicted to be referred to after moving based on a current position, moving direction and/or moving speed of a terminal apparatus, the terminal apparatus inquires of a communication information area managing section whether a position associated with the content is in a communication area, and when the position is outside the communication area, selects at least one communication section with communication-capable channel quality, and acquires and stores the content predicted to be referred to using the selected communication section. It is thereby possible to refer to the content when a position in response to the content predicted to be referred to is outside a communication-capable area.

Abstract: In a broadcast using packet transmission, zapping-data and program data are packet-transmitted 105 from a transmitting apparatus 106. A receiving apparatus 111 receives 115 and stores 109 the data and zapping-data. Until the program data selected upon program reproduction becomes reproducible, zapping-data is reproduced 108, whereby the viewer can know the information about a program without waiting for a lapse of reproduction wait time after switching a program channel.

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.
