摘要： In a data providing server 1101, whether or not specified compressed content data D51 generated by means of a specified compression coding method corresponding to terminal identification information has been stored in a content database 1113 is detected, according to content specifying data D53 transmitted from a portable dedicated terminal 1104. If the specified compressed content data D51 has been stored, the data providing server 1101 reads and transmits this to the portable dedicated terminal 1104. And if the specified compressed content data D51 has not been stored, the data providing server 1101 generates the specified compressed content data D51 by means of the specified compression coding method, and transmits this to the portable dedicated terminal 1104. Thereby, the specified compressed content data D51 generated by means of a specified decoding method can be properly provided to the portable dedicated terminal 1104, and the user can easily view a content based on the content data.

摘要翻译： 在数据提供服务器1101中，根据从便携式设备1101发送的内容指定数据D53，检测是否已经将与终端识别信息相对应的特定压缩编码方法生成的指定的压缩内容数据D51存储在内容数据库1113中 专用终端1104.如果已经存储了指定的压缩内容数据D51，则数据提供服务器1101读取并发送给便携式专用终端1104.如果指定的压缩内容数据D51尚未被存储，则数据提供服务器1101生成 通过指定的压缩编码方法指定的压缩内容数据D51，并将其发送到便携式专用终端1104.由此，可以将指定的解码方法生成的规定的压缩内容数据D51适当地提供给便携式专用终端 1104，并且用户可以基于内容容易地查看内容 数据。
