  • the number of the second(s) of the continuous data to be read out is arbitrary.
  • the recording/reproducing apparatus 7103 if the position information is recorded in the format shown in FIGS. 75 and 76 , since it is also possible to determine the readout position of the data continuing for a time-period of several seconds desired, by referring to that data, therefore the process is completed with provision that a setup is made to repeat the processing, such as, determining the next coming readout position depending on the double-speed.
  • a series of processes is executed, in an equivalent manner when receiving the broadcasting, such as, from division of the data received on the network I/F 25 into the video/audio, etc., sequentially, within the multiplex/demultiplex portion 29 , up to deciding process within the video decoder portion 30 , the video conversion process within the video conversion process portion 32 , and displaying on the display 47 .
  • the system control portion 51 changes the decoding process method of the video decoder portion 30 to decode only the “I” picture, and the process advances into S 8002 .
  • the recording/reproducing apparatus 7103 changes the readout/transmission method for the recorded program data, and thereby outputs the “I” picture data for one (1) piece by one (1) time.
  • the video decoder portion since the video decoder portion is set up to process the “I” picture only in S 8001 , it does not matter with, in the operation thereof, if transmitting data other than the “I” picture. Processing only the “I” picture data enables reduction of the processing load. If the recording/reproducing apparatus 7103 records the position information when recording, as was shown in FIGS. 75 and 76 , then by referring to this, it is possible to determine starting position and the ending portion for reading out the “I” picture.
  • a sequence set up for the special reproduction to be executed in S 7803 differs from in the content of processing depending on the video format recorded. If the recorded video is the program of the 2-viewpoints separate ES transmission method, it is enough to execute the processes similar to those shown in FIG. 80 , however in S 8002 , the recording/reproducing apparatus 58 selects only the main 1 ES, so as to output it, and after making a setup to provide the “I” picture at a necessary time-interval, completes the process.
  • FIG. 81 An example of a processing sequence when the recorded video is the 2-viewpoints same ES transmission method is shown in FIG. 81 .
  • S 8101 is made a setup to convert the video, if being for two (2) viewpoints, such as, the “Side-by-Side” method, etc., for example, into that for displaying one (1) viewpoint for use of the 2D view/listen, within the video conversion process portion 32 , and the process advances into S 8102 .
  • S 8102 is made a setup similar to that in S 8002 , and thereafter is completed the process.
  • the processing may be done, so that the interval for displaying the “I” picture comes to be a fine display interval equivalent to that when reproducing the 2D, such as, 100 milliseconds, etc.
  • a control is executed; i.e., stopping the 3D viewing/listening function of the 3D view/listen assisting device 3502 , or showing the same picture for the right-side eye and the left-side eye (e.g., displaying “M” picture, again, at the timing for displaying “S” picture shown in FIG. 37A , and displaying “L” picture, again, at the timing for displaying “R” picture shown in FIG. 39A ) while keeping the 3D viewing/listening function of the 3D view/listen assisting device 3502 as it is.
  • FIG. 83 is shown an example of a sequence of the processing.
  • S 8301 if it indicates to have the 3D video data by referring to the 3D identification information of the corresponding reproduction content, the process advances into S 8302 , on the contrary if not have the 3D video data into S 8303 .
  • the method for refereeing to the identification information rather than accessing to the file every time, if making an access to the file only one (1) time before starting the reproduction, so as to record it as a local variable, herein after the value of the 3D/2D identification information can be determined by referring to the corresponding variable when determining; there is an advantage of lightening the processing load.
  • a setup is made to execute the process for the 3D video data, which was explained in FIGS. 79 to 81 mentioned above, irrespective of that the reproduction display position is the 3D video data or the 2D video data, and then the process is completed.
  • the process is executed for converting the input video into the 2D video, if it is the 3D video of, such as, the “Side-by-Side” method or the “Top-and-Bottom” method, as was explained in FIG. 40 , for example, in the video conversion process portion 32 , but no conversion process is done if the input video is 2D video.
  • S 8303 is conducted such process as was shown in FIG. 78 , so as to make a setup of executing the process depending on if the video data at the reproduction position is the 3D video data or the 2D video data, and the process is completed.
  • the process is executed for converting the input video into the 2D video, if it is the 3D video of, such as, the “Side-by-Side” method or the “Top-and-Bottom” method, as was explained in FIG. 40 , for example, in the video conversion process portion 32 , but no conversion process is done if the input video is 2D video.
  • the determination may be made if the program name (or may be called a “program title”), which is included in the program-common information, is a title or not, having a meaning to include the 3D video.
  • program name or may be called a “program title”
  • the determination of if including the 3D video scene or not may be made with methods other than that.
  • the reproduction content of the 2-viewpoints same ES transmission method does not hold the 3D program details descriptor in the user data area or the addition information area thereof, for the receiving apparatus 4 , sometimes, it is difficult to determine of 2D/3D of the reproduction scene. Then, a possibility can be considered that the 2D video is displayed in the 3D format, in particular, when such exchange generates between the 2D video and the 3D video, during the high-speed search.
  • the display format during the special reproduction may be treated as the 2D. With doing this, a possibility of showing an uncomfortable video to the user upon an erroneous display format, and there is obtained an effect of achieving the special reproduction view/listenable easily.
