Abstract

An information device is provided that includes a communication component and a controller. The communication component communicates with an external device. The controller downloads video data from the external device through the communication component. The controller performs processing for playing the video data. The controller executes an application for playing the downloaded video data. The controller sends a download request for each divided video data, with the divided video data being obtained by dividing up the video data.

First claim

What is claimed is:

1. An information device comprising:
a communication component that communicates with an external device; and
a controller that downloads video data from the external device through the communication component, performs processing to convert a format of the video data into a playable format and executes an application for playing the video data,
the controller sending a download request for each divided video data to sequentially download the divided video data, with the divided video data being obtained by dividing up the video data,
the processing by the controller to convert the format of the video data into the playable format including dividing the divided video data into a plurality of divided files and producing a playlist file for a playback instruction of the divided files every time the divided video data is downloaded.

2. The information device according to claim 1 , wherein
the controller sends a plurality of download requests sequentially specifying contiguous data regions of a data file of the video data at a predetermined data interval to download each of the contiguous data regions of the data file of the video data as the divided video data.

3. The information device according to claim 2 , wherein
the controller repeats sending the download requests for the divided video data until download of the video data is complete.

4. The information device according to claim 1 , wherein
the controller updates the playlist file produced based on a first set of the divided video data when a second set of the divided video data is downloaded.

5. The information device according to claim 1 , wherein
the controller repeats producing the divided files and updating the playlist file until download of the video data is, complete.

6. The information device according to claim 2 , wherein
when download of the video data is interrupted, the controller corrects playback time of the video data to correspond to playback time of incomplete video data that has been downloaded by the time the download is interrupted.

7. The information device according to claim 6 , wherein.
the controller displays the corrected playback time on a display component when the playback time of the video data is corrected.

8. The information device according to claim 2 , wherein
when download of the video data is resumed and overlapping video data is downloaded that includes an overlapping data portion that partially overlaps incomplete video data that has been downloaded by the time the download is interrupted, the controller deletes the overlapping video data.

9. The information device according to claim 2 , wherein
when download of the video data is resumed and overlapping video data is downloaded that includes an overlapping data portion that partially overlaps incomplete video data that has been downloaded by the time the download is interrupted, the controller deletes the overlapping data portion of the overlapping video data.

10. The information device according to claim 2 , wherein
when download of the video data is resumed and overlapping video data is downloaded that includes an overlapping data portion that partially overlaps incomplete video data that has been downloaded by the time the download is interrupted, the controller selectively plays a data portion of the overlapping video data other than the overlapping data portion.

11. The information device according to claim 2 , wherein
the controller downloads the divided video data corresponding to the video data for a period after a designated playback location and performs the processing for playing the video data on the downloaded divided video data.

12. The information device according to claim 11 , wherein
the controller downloads the divided video data corresponding to the video data for the period after the designated playback location in response to an input during playing the video data at the designated playback location.

13. The information device according to claim 2 , wherein
the controller sends a next subsequent one of the download requests after the download is completed for the prior one of the contiguous data regions of the data file of the video data.
