Abstract

A method of receiving and playing a composite video, wherein the composite video includes at least a video asset and a non-video asset in separate files. The method comprising: receiving the non-video asset; receiving at least a portion of the video asset; buffering the at least a portion of the video asset in a buffer; delaying playback of the composite video until (a) the non-video asset is downloaded and (b) the at least a portion of the video asset received is sufficient under existing conditions that the video asset can be played in real time without emptying the buffer before the end of the video asset; and playing, after the delaying, the composite video.

Claims

1. A method of receiving and playing a composite video, wherein the composite video includes at least a video asset and a non-video asset in separate files, the method comprising:

receiving the non-video asset;

receiving at least a portion of the video asset;

buffering the at least a portion of the video asset in a buffer;

delaying playback of the composite video until (a) the non-video asset is downloaded and (b) the at least a portion of the video asset received is sufficient under existing conditions that the video asset can be played in real time without emptying the buffer before the end of the video asset; and

playing, after the delaying, the composite video.

2. The method of claim 1, further comprising:

displaying, during the delaying playback, a download progress bar, the progress bar representing the following equation;

Progress=(x·

amount of non-video asset download)+(y·

amount start video asset downloaded)

where;

x and y are predetermined values for which x+y=100%; and

“

start video asset”

is a portion of the video asset that, under existing conditions, needs to be downloaded before the video asset can be played in real time without emptying the buffer before the end of the video asset.

3. The method of claim 2, where x is 20% and y is 80%.

4. The method of claim 1, wherein the existing conditions include at least the download rate, the length of the video asset, and the amount of time it will take to download the entire video asset.

5. The method of claim 1, wherein the video and non-video assets are synchronized, and the composite video include portions of the non-video asset displayed during discrete portions of playback of the video asset.

6. The method of claim 1, further comprising receiving instructions for when to play discrete portions of the non-video asset relative to the video asset.

7. The method of claim 6, wherein the instructions are part of the same file as the video asset.

8. The method of claim 1, wherein the non-video asset includes an image of a background on which the video asset will be displayed.

9. The method of claim 1, wherein the non-video asset includes text that will appear during a predetermined portion of the playing of the video asset.

10. The method of claim 1, wherein the non-video asset includes at least one test question, the method further comprising displaying the test question after playback of the video asset ends.

11. A method of playing a composite video, the method comprising:

downloading a non-video asset file, the non-video asset file including a library of non-video assets;

receiving a video;

buffering the video;

receiving instructions that (a) select the non-video asset from the library, (b) identify where in a display the non-video asset is to be displayed, and (c) when, relative to the video, the non-video asset is to be displayed;

playing the video and the selected non-video assets from the library, synchronized according to the instructions.

12. The method of claim 11, wherein the playing commences when the non-video asset file is downloaded and a sufficient portion of the video has been buffered such that the video can be played in real time in its entirety.

13. The method of claim 11, wherein the video and the instructions are part of a common file.

14. The method of claim 11, wherein the video is in a file different from the non-video asset file.

15. The method of claim 11, wherein the non-video asset includes an image of a background on which the video will be displayed.

16. The method of claim 11, wherein the non-video asset includes at least one test question, the method further comprising displaying the test question after playback of the video ends.

17. The method of claim 11, further comprising displaying a download progress bar, the bar representing a combination of (a) a portion of the non-video asset downloaded and (b) a portion of the video asset buffered relative to the minimum amount of the video needed to be buffered so that the video can play in its entirety in real time.

18. The method of claim 11, further comprising delaying the playing until (a) the entire non-video asset is downloaded and (b) the part of the entire video asset received is sufficient under existing conditions that the video asset can be played in real time without emptying the buffer before the end of the video asset.
