Abstract

Techniques for adaptive content transmission are described herein. During transmission of a content item, a network connection may be monitored to collect data corresponding to one or more network conditions associated with the transmission of the content item. Such network conditions may include, for example, network throughput, available network bandwidth, network latency and others. The collected data may be used to dynamically adjust one or more transmission attributes in connection with the transmitted content item. The one or more transmission attributes may be determined for adjustment at any desired transmission interval.

First claim

What is claimed is:

1. One or more server compute nodes comprising:
one or more processors; and
one or more memories storing instructions that, upon execution by the one or more processors, cause the one or more server compute nodes to perform operations comprising:
receiving a command to initiate a streaming transmission of a video game over an electronic network to a client;
applying a first proportion of forward error correction to a first frame associated with the video game, wherein the first proportion of forward error correction corresponds to a ratio of a number of redundant bits associated with the first frame in comparison to a number of source bits associated with the first frame;
transmitting the first frame to the client over the electronic network as part of the streaming transmission of the video game;
receiving information corresponding to at least one of a throughput, a bandwidth, a loss rate or a latency associated with the transmitting of the first frame;
adjusting, based at least in part on the information, application of forward error correction to the streaming transmission of the video game whereby different proportions of forward error correction are applied to different frames within the streaming transmission of the video game, wherein the adjusting comprises:
determining, based at least in part on the information, a second proportion of forward error correction for application to a second frame associated with the video game, wherein the second proportion is different from the first proportion, wherein the second proportion of forward error correction corresponds to a ratio of a number of redundant bits associated with the second frame in comparison to a number of source bits associated with the second frame; and

applying the second proportion of forward error correction to the second frame; and
transmitting the second frame to the client over the electronic network as part of the streaming transmission of the video game.

2. The one or more compute nodes of claim 1 , wherein the second proportion of forward error correction is also determined based at least in part on at least one of an encoding bitrate, a frame rate or a resolution associated with the second frame.

3. The one or more compute nodes of claim 1 , wherein at least one of an encoding bitrate, a frame rate or a resolution associated with the second frame are determined based at least in part on the second proportion of forward error correction.

4. The one or more compute nodes of claim 1 , wherein user datagram protocol is employed to at least in part perform the streaming transmission of the video game.

5. A computer-implemented method executed by one or more server compute nodes for streaming transmission of a video game over an electronic network to a client comprising:
receiving a command to initiate the streaming transmission of the video game over the electronic network to the client;
applying a first proportion of forward error correction to a first frame associated with the video game, wherein the first proportion of forward error correction corresponds to a ratio of a number of redundant bits associated with the first frame in comparison to a number of source bits associated with the first frame;
transmitting the first frame to the client over the electronic network as part of the streaming transmission of the video game;
receiving information corresponding to at least one of a throughput, a bandwidth, a loss rate or a latency associated with the transmitting of the first frame;
adjusting, based at least in part on the information, application of forward error correction to the streaming transmission of the video game whereby different proportions of forward error correction are applied to different frames within the streaming transmission of the video game, wherein the adjusting comprises:
determining, based at least in part on the information, a second proportion of forward error correction for application to a second frame associated with the video game, wherein the second proportion is different from the first proportion, wherein the second proportion of forward error correction corresponds to a ratio of a number of redundant bits associated with the second frame in comparison to a number of source bits associated with the second frame; and
applying the second proportion of forward error correction to the second frame; and

transmitting the second frame to the client over the electronic network as part of the streaming transmission of the video game.

6. The computer-implemented method of claim 5 , wherein the second proportion of forward error correction is also determined based at least in part on at least one of an encoding bitrate, a frame rate or a resolution associated with the second frame.

7. The computer-implemented method of claim 5 , wherein at least one of an encoding bitrate, a frame rate or a resolution associated with the second frame are determined based at least in part on the second proportion of forward error correction.

8. The computer-implemented method of claim 5 , wherein the information further corresponds to at least one of error rate, distortion rate, or packet jitter.

9. The computer-implemented method of claim 5 , wherein an encoding bitrate of the second frame is decreased relative to an encoding bitrate of the first frame based at least in part on a determination that the second proportion of forward error correction is greater than the first proportion of forward error correction.

10. The computer-implemented method of claim 5 , wherein the streaming transmission of the video game is performed as part of a file download procedure.

11. The computer-implemented method of claim 5 , wherein the second proportion of forward error correction is also determined based at least in part on at least one of an identity of the video game, an identity of the client, a location of the client, one or more capabilities of the client or a transmission protocol associated with the streaming transmission of the video game.

12. The computer-implemented method of claim 5 , wherein the second frame immediately follows the first frame.

13. The computer-implemented method of claim 5 , wherein the second frame does not immediately follow the first frame.

14. The computer-implemented method of claim 5 , wherein the first and second frame comprise video content.

15. The computer-implemented method of claim 5 , wherein the first and second frame comprise audio content.

16. One or more non-transitory computer-readable storage media having stored thereon instructions that, upon execution on one or more server compute nodes, cause the one or more server compute nodes to perform operations comprising:
receiving a command to initiate a streaming transmission of a video game over an electronic network to a client;
applying a first proportion of forward error correction to a first frame associated with the video game, wherein the first proportion of forward error correction corresponds to a ratio of a number of redundant bits associated with the first frame in comparison to a number of source bits associated with the first frame;
transmitting the first frame to the client over the electronic network as part of the streaming transmission of the video game;
receiving information corresponding to at least one of a throughput, a bandwidth, a loss rate or a latency associated with the transmitting of the first frame;
adjusting, based at least in part on the information, application of forward error correction to the streaming transmission of the video game whereby different proportions of
