- a program selection unit for instructing the separation unit on video data to be extracted, an identification information storage unit for storing the identification data separated and extracted by the separation unit, and a separation and extraction by the separation unit
- the progressive scanning video decoding unit that decodes the extracted progressive scanning image data and outputs it as a signal, and the interlaced scanning that is separated and extracted by the separation unit.
- An interlaced scanning video decoding unit for decoding and outputting as an elephant signal, and a video scanning method of the video data selected by the operator based on the information in the identification information storage unit are determined.
- a decoding command is issued to the scanning video decoding unit
- a scanning command unit for issuing a decoding command to the interlaced scanning video decoding unit is provided.
- the video signal from the progressive scanning video decoding unit and the interlaced scanning video decoding unit is input, and the instruction from the scanning method instruction unit is issued. Further comprising an output switching unit for switching and outputting video signals from the progressive scanning video decoding unit and the interlaced scanning video decoding unit. Therefore, it is possible to correctly reproduce and display the ⁇ data of either method on a display device that supports both scanning methods.
- the output switching unit outputs the video data of either one of the scanning methods as it is, and outputs the other one of the scanning methods.
- the data reproducing apparatus data of a plurality of programs including both the interlaced scanning video data and the progressive scanning video data are stored in each program. And a video data to be multiplexed and transmitted together with information for identifying whether the video data of each program included in the event If report table is a progressive scanning system or an interlaced scanning system.
- the video data reproducing device may select the content of the video data by time of each program based on the event information table and the identification information.
- a program table showing the scanning method of the video data is created, and a program table creating means for outputting this as visible information on the display screen of the display unit is provided. It is possible to check the inspection method and prevent erroneous selection.
- a program composed of video data in a format that cannot be reproduced by the reproducing device is selected.
- a notifying means for notifying that reproduction is impossible as visible information or auditory information the effect of preventing erroneous selection by the viewer can be increased.
- the program table creating means displays only a program consisting of other data in a format that can be reproduced by the reproducing apparatus. By doing so, the effect of preventing erroneous selection by the viewer can be increased.
