Abstract

A method is provided in one example embodiment and includes receiving a request for video content from a client device and accessing a common format representation for a requested chunk within the video content. The common format representation is provided in one or more files that include metadata indicative of one or more counters. The method can also include using the common format representation in conjunction with a deterministic equation to identify a predicted size of an output to be sent to the client device; and using the predicted size of the output to initiate transmitting at least a portion of a response to the client.

Claims

1. A method, comprising:

receiving a request for video content from a client device;

accessing a common format representation for a requested chunk within the video content, wherein the common format representation is provided in one or more files that include metadata indicative of one or more counters;

using the common format representation in conjunction with a deterministic equation to identify a predicted size of an output to be sent to the client device; and

using the predicted size of the output to initiate transmitting at least a portion of a response to the client.

2. The method of claim 1, further comprising:

adding buffering as part of the response to pad at least some packets being provided to the client device.

3. The method of claim 2, wherein the buffering includes one or more null transport stream (TS) packets for moving picture experts group (MPEG)-TS based formats.

4. The method of claim 2, wherein the buffering includes one or more empty boxes associated with an International Organization for Standardization (ISO)-base media file format (BMFF) (ISO-BMFF).

5. The method of claim 1, wherein the accessing includes identifying common format indexing and common format data for the requested chunk.

6. The method of claim 5, wherein the common format indexing includes metadata that includes the one or more counters that can be read by a packager module configured to translate a target format request to a common format request, and to fetch the common format data and the common format indexing data from a content delivery network (CDN).

7. The method of claim 1, wherein the one or more counters include a number of TS packets per packet identifier (PID) within the common format.

8. The method of claim 1, wherein the one or more counters include an amount of data in bytes of raw video.

9. The method of claim 1, wherein the one or more counters include an amount of data in bytes of audio video.

10. The method of claim 1, wherein the one or more counters include an amount of raw data per PID.

11. The method of claim 1, further comprising:

setting one or more content length headers based on the predicted size of the output.

12. The method of claim 1, further comprising:

setting a buffer based on the predicted size of the output.

13. The method of claim 1, further comprising:

reading particular video data associated with the requested chunk from a disk;

translating the particular video data into a format associated with the client device; and

transmitting at least a portion of the response to the client device.

14. One or more non-transitory tangible media that includes code for execution and when executed by a processor operable to perform operations comprising:

receiving a request for video content from a client device;

accessing a common format representation for a requested chunk within the video content, wherein the common format representation is provided in one or more files that include metadata indicative of one or more counters;

using the common format representation in conjunction with a deterministic equation to identify a predicted size of an output to be sent to the client device; and

using the predicted size of the output to initiate transmitting at least a portion of a response to the client.

15. The non-transitory tangible media of claim 14, the operations further comprising:

adding buffering as part of the response to pad at least some packets being provided to the client device.

16. The non-transitory tangible media of claim 14, the operations further comprising:

setting one or more content length headers based on the predicted size of the output.

17. A network element, comprising:

a processor;

a memory; and

a size prediction module, wherein the network element is configured to;

receive a request for video content from a client device;

access a common format representation for a requested chunk within the video content, wherein the common format representation is provided in one or more files that include metadata indicative of one or more counters;

use the common format representation in conjunction with a deterministic equation to identify a predicted size of an output to be sent to the client device; and

use the predicted size of the output to initiate transmitting at least a portion of a response to the client.

18. The network element of claim 17, wherein the network element is further configured to:

add buffering as part of the response to pad at least some packets being provided to the client device.

19. The network element of claim 17, wherein the network element is further configured to:

set one or more content length headers based on the predicted size of the output.

20. The network element of claim 17, further comprising:

a packager module configured to;

read the one or more counters;

translate a target format request to a common format request; and

fetch common format data and common format indexing data from a content delivery network (CDN).
