Abstract

There is provided a system having a content server having a hardware processor and a system memory, a content management software code stored in the system memory. The hardware processor being configured to execute the content management software code to receive a search request for a video content, and identify a plurality of video content streams based on the search request. For each of the plurality of video content streams to determine a plurality of video content threads for downloading the video content stream in multiple segments, execute the plurality of video content threads concurrently at least in part for downloading the video content stream, and reassemble the video content stream from the plurality of video content threads.

Claims

1. A system comprising:

a content server having a hardware processor and a system memory;

a content management software code stored in the system memory;

the hardware processor being configured to execute the content management software code to;

receive a search request from a client device for a video content, the search request including a time code corresponding to a location within the video content;

identify a plurality of video content streams based on the search request;

for each of the plurality of video content streams;

determine a plurality of video content threads for downloading the video content stream in multiple segments;

execute the plurality of video content threads concurrently at least in part for downloading the video content stream; and

reassemble the video content stream from the plurality of video content threads;

dynamically generate in real-time, in response to and after the search request is received, a thumbnail from the location corresponding to the time code from each of the plurality of video content streams identified based on the search request; and

transmit, to the client device, the thumbnail that was dynamically generated in real-time, in response to and after the search request, for each of the plurality of video content streams.

2. The system of claim 1, wherein identifying the plurality of video content streams based on the search request comprises searching a closed caption file corresponding to a dialogue or script of a video content stream of the plurality of video content streams.

3. The system of claim 1, wherein the content server comprises a plurality of virtual machines, and wherein the hardware processor is configured to execute the content management software code to download the plurality of video content threads concurrently at least in part by assigning one or more of the plurality of video content threads to each of the plurality of virtual machines.

4. The system of claim 1, wherein the hardware processor is further configured to execute the content management software code to determine the plurality of video content threads for downloading the video content stream into multiple segments based on a size of the video content stream.

5. The system of claim 1, wherein the hardware processor is further configured to execute the content management software code to, prior to executing the plurality of video content threads, transcode the video content stream into a lower resolution.

6. The system of claim 1, wherein the search request includes a height and a width aspect ratio of the thumbnail.

7. The system of claim 1, wherein the thumbnail for each of the plurality of video content streams is not generated and not stored in the system memory prior to the search request.

8. The system of claim 1, wherein the time code is one of a temporal location or a temporal range.

9. A method for use by a system including a content server having a hardware processor and a system memory storing a content management software code, the method comprising:

receiving, using the hardware processor, a search request from a client device for a video content, the search request including a time code corresponding to a location within the video content;

identifying, using the hardware processor, a plurality of video content streams based on the search request;

for each of the plurality of video content streams;

determining a plurality of video content threads for downloading the video content stream in multiple segments;

executing the plurality of video content threads concurrently at least in part for downloading the video content stream; and

reassembling the video content stream from the plurality of video content threads;

dynamically generating in real-time, in response to and after the search request is received, a thumbnail from the location corresponding to the time code from each of the plurality of video content streams identified based on the search request; and

transmitting, to the client device, the thumbnail that was dynamically generated in real-time, in response to and after the search request, for each of the plurality of video content streams.

10. The method of claim 9, wherein the identifying comprises searching a closed caption file corresponding to a dialogue or script of a video content stream of the plurality of video content streams.

11. The method of claim 9, wherein the content server comprises a plurality of virtual machines, and wherein the executing comprises assigning one or more of the plurality of video content threads to each of the plurality of virtual machines.

12. The method of claim 9, wherein the determining is based on a size of the video content stream.

13. The method of claim 9, wherein prior to the executing, the method further comprises transcoding the video content stream into a lower resolution.

14. The method of claim 9, wherein the search request includes a height and a width aspect ratio of the thumbnail.

15. The method of claim 9, wherein the thumbnail for each of the plurality of video content streams is not generated and not stored in the system memory prior to the search request.

16. The method of claim 9, wherein the time code is one of a temporal location or a temporal range.

17. A method for use by a system including a content server having a hardware processor and a system memory storing a content management software code, the method comprising:

receiving, using the hardware processor, a search request from a client device for a video content, the search request including a temporal range corresponding to a video frame within the video content;

identifying, using the hardware processor, a plurality of video content streams based on the search request;

for each of the plurality of video content streams;

determining a plurality of video content threads for downloading the video content stream in multiple segments;

executing the plurality of video content threads concurrently at least in part for downloading the video content stream; and

reassembling the video content stream from the plurality of video content threads;

dynamically generating in real-time, in response to and after the search request is received, one or more thumbnails from the video frame corresponding to the temporal range from each of the plurality of video content streams identified based on the search request; and

transmitting, to the client device, the one or more thumbnails that were dynamically generated in real-time, in response to and after the search request, for each of the plurality of video content streams.

18. The method of claim 17, wherein the content server comprises a plurality of virtual machines, and wherein executing the plurality of video content threads concurrently comprises assigning one or more of the plurality of video content threads to each of the plurality of virtual machines.

19. The method of claim 17, wherein the plurality of video content threads are determined based on a size of the video content stream.

20. The method of claim 17, wherein the search request includes a height and a width aspect ratio of at least one of the one or more thumbnails.
