INFORMATION PROCESSING APPARATUS AND METHOD, AND PROVIDING MEDIUM |
摘要 |
When a tuner (2) receives EPG service information and EPG program information transmitted together with broadcasting data, a making unit (12) in the tuner (2) makes an EPG service list about receivable channels from the EPG service information by using a descriptor conforming to a general-purpose format, such as the AV/C protocol. A changing unit (13) in the tuner (2) converts the EPG program information into an EPG event list by using a descriptor conforming to a general-purpose format, such as the AV/C protocol. Therefore, the EPG service list and EPG event list can be read from any device under the control according to the protocols of the general-purpose formats used, and the EPG data can be easily handled by any other device other than the tuner.
