1. An information processing system, comprising:
a first electronic apparatus; and
a second electronic apparatus connectable to the first electronic apparatus through a network, the first electronic apparatus including:
a control device;
an information acquiring portion to acquire copy control information indicative of at least whether copy of a content is permitted or not;
a meta-data generating portion to generate meta-data containing in a specific area the copy control information acquired by the information acquiring portion;
a data transmission processing portion to transmit the meta-data generated by the meta-data generating portion to the network; and
a transcode processing portion capable of converting one content to contents of different qualities by executing different transcode processes,
the meta-data generating portion generating the meta-data containing, in the specific area, information indicative of permission of copy for one generation, with respect to a content whose quality is lowered under a predetermined reference value by a transcode process, even if the copy control information indicates that no more copy is permitted,
the second electronic apparatus including:
a meta-data acquiring portion to acquire the meta-data transmitted to the network;
a meta-data analyzing portion to analyze information contained in the meta-data acquired by the meta-data acquiring portion; and
an information display processing portion to display information indicative of a kind of a process that is permitted to be performed with respect to the content, based on the copy control information contained in the information analyzed by the meta-data analyzing portion,
the specific area in the meta-data containing description of attribute information relating to a resource of the content, and the copy control information being described as a part of the attribute information.
