Abstract

One embodiment of a system for rendering media files comprises a computer configured to determine media file formats that are used by media rendering devices connected to a network and to determine media files available on the network. The computer generates media shadow files of media file formats used by the media rendering devices to accompany existing media files available on the network in alternative formats.

Claims

1. A system for rendering media files comprising:

a computer to determine media file formats used by media rendering devices connected to a network, to store the determined media file formats in a data structure, and to determine existing media files available on the network,

wherein the computer generates media shadow files for each of the determined media file formats used by the media rendering devices to accompany each of a number of existing media files available in an initial file format on the network, each of the media shadow files imitating each of the determined media file formats accompanying each existing media files and indicating that a fully transcoded media file is available in the determined media file formats used by the media rendering devices;

wherein the media shadow files each comprise an initial portion less than the whole of media content of each of the existing media files in a particular file format and further comprises instructions for transcoding a remaining portion of the media content from the initial file format into the particular file format;

wherein the initial portion of each of the media content associated with each of the media shadow files is streamed while the remaining portion of the media content of each of the media shadow files are transcoded in real time from the existing media files accompanied with the media shadow files; and

wherein, after delivery of the media content associated with each of the media shadow files, the remaining portion of the media content of each of the media shadow files is deleted.

2. The system of claim 1, wherein each of the media shadow files comprise an indication that each of the media shadow files contain the initial portion of media content in the particular file format.

3. The system of claim 2, wherein the computer generates media contents associated with each of the existing media files in the particular file format by converting a media file in the initial file format to the particular file format after the computer receives an initial request to deliver contents of a particular media shadow file among the media shadow files.

4. The system of claim 3, wherein the computer delivers the contents of the media shadow file by streaming the contents to a requesting device.

5. The system of claim 2, wherein the indication comprises a file extension of a codec format of the particular file format.

6. The system of claim 1, wherein the computer stores a list of the media rendering devices in the data structure and updates the data structure based on a change in the media rendering devices connected to the network.

7. The system of claim 1, wherein the data structure is a table.

8. A non-transitory computer readable medium having instructions executed by a computer which causes the computer to:

determine media file formats used by media rendering devices connected to a network;

store the determined media file formats in a data structure;

determine media files available on the network; and

generate media shadow files for each of the determined media file formats used by the media rendering devices to accompany each of a number of existing media files available in an initial file format on the network, each of the media shadow files imitating each of the associated determined media file formats accompanying each existing media files and representing that a fully transcoded media file is available in the determined media file formats used by the media rendering devices;

wherein the media shadow files each comprise an initial portion less that the whole of media content of each of the existing media files in a particular file format and further comprises instructions for transcoding a remaining portion of the media content from the initial file format into the particular file format;

wherein the initial portion of media of each of the media content associated with each shadow files is streamed while the remaining portion of the media content of each of the media shadow files are transcoded in real time from the existing media files accompanied with the media shadow files; and

wherein, after delivery of the media content associated with each of the media shadow files, the remaining portion of the media content of each of the media shadow files is deleted.

9. The non-transitory computer readable medium of claim 8, wherein each of the media shadow files comprise an indication that each of the media shadow files contain the initial portion of media contents in the particular file format.

10. The non-transitory computer readable medium of claim 9, further comprising instructions to:

generate media contents associated with each of the existing media files in the particular file format by converting a media file in the initial file format to the particular file format after the computer receives an initial request to deliver contents of a particular media shadow file.

11. The non-transitory computer readable medium of claim 10, further comprising instructions to:

deliver the contents of the media shadow file by streaming the contents to a requesting device.

12. A method of rendering media files comprising:

determining media file formats used by media rendering devices connected to a network;

storing the determined media file formats in a data structure of a computing device;

determining media files available on the network; and

generating media shadow files for each of the determined media file formats used by the media rendering devices to accompany each of a number of existing media files available in an initial file format on the network;

wherein each of the media shadow files imitate each of the determined media file formats accompanying each existing media files and signify to each of the media rendering devices that a fully transcoded media file is available in the determined media file formats used by the media rendering devices;

wherein the media shadow files each comprise an initial portion less than the whole of media content of each of the existing media files transcoded by a processor of the computing device in the particular file format and further comprises instructions for transcoding a remaining portion of the media content from the initial file format into the particular file format;

wherein the initial portion of each of the media content associated with each of the media shadow files is streamed while the remaining portion of each of the media shadow files are transcoded in real time from the existing media files accompanied with the media shadow files; and

wherein, after delivery of the media content associated with each of the media shadow files, the remaining portion of the media content of each of the media shadow files is deleted.

13. The method of claim 12, wherein each of the media shadow files comprise an indication that each of the media shadow files contain the initial portion of media contents in the particular file format.

14. The method of claim 13 further comprising:

generating media contents associated with each of the existing media files in the particular file format by converting a media file in the initial file format to the particular file format after the computing device receives an initial request to deliver contents of a particular media shadow file.

15. The method of claim 14 further comprising:

delivering the contents of the media shadow file by streaming the contents to a requesting device.
