The option information is recorded in the storage medium 34 in a directory structure as shown in FIG. 8 in association with the broadcast program to be recorded.

  FIG. 8 is a diagram showing a directory structure when the broadcast program and option information are recorded in the storage medium 34. The directory D11 during recording shown in FIG. 8A is not uniquely determined in consideration of the time axis. Therefore, after the recording is completed, as shown in FIG. 8B, a directory D12 describing the start date and time of the program to be recorded is created, and the recorded broadcast program and the acquired option information are moved under the created directory. To do. It should be noted that <YYYYMMDDDHHMM> described at the top of the directory D12 in FIG. 8B indicates that YYYY is the year (four digits display), MM is the month (two digits display), DD is the day (two digits display), HH Represents time (2-digit display) and MM represents minutes (2-digit display).

  FIG. 9 is a flowchart showing the operation content of the receiving terminal 20 when viewing the recorded program.

  Referring to FIG. 9, in step S11, a recorded program is selected from a recorded program list (not shown). The recorded program list is a correspondence table between program titles and program storage destination directories. By selecting the recorded program, the directory in which the program is stored is specified in step S12. In step S13, it is determined whether option information is stored in the storage destination directory.

  If option information is stored in step S13, in step S14, the broadcast program is reproduced and a process corresponding to the extension of the option information is performed. For example, if the extension of the option information is “apes”, it is determined that the option information is a voice PES (Packetized Elementary Stream). At this time, processing such as reproducing the sound of the sound PES instead of the sound included in the broadcast program is performed. If the extension of the option information is “bml”, the browser 27 is activated to display the corresponding BML document. If option information is not stored in step S13, only the broadcast program is reproduced in step S15.

  In the above embodiment, a case has been described in which a movie program is to be recorded, but other programs can also be recorded. For example, when an English conversation program is to be recorded, as option information, (1) other words and pronunciation information related to the program content, (2) cross-cultural information related to the program content, and (3) program content are shown. Text, etc. can be selected. Other processes are the same as those in the embodiment described so far. In other words, even if the target of recording is an English conversation program, it can be handled by simply replacing option information.

  In the embodiment of the present invention, a portable receiving terminal has been described as an example of the receiving terminal 20, but it is not necessarily required to be portable. Further, the recording reservation and execution are described with the receiving terminal 20 set in the cradle 50. However, the recording reservation and execution can be performed only by the receiving terminal 20. Further, from the viewpoint of the program provider, a broadcast program may be free, and a mechanism may be provided for charging optional information that supplements the content of the broadcast program and enhances the content.

  As described above, according to the embodiment of the present invention, in addition to the electronic program guide EPG from the low-level event information table L-EIT, by acquiring the web electronic program guide WebEPG from the web electronic program guide server, It is possible to provide information guidance according to specific needs that are not suitable for broadcast waves.

  In addition, since the desired content is stored in the receiving terminal during viewing, the stress on the user can be reduced as compared with a mode in which the communication content is accessed during viewing. This is particularly effective when the size of the file acquired from the communication content server is large. Moreover, there is no need to worry about the fact that the communication content destination has been deleted or the communication environment of the destination is bad.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
