Methods and devices for adapting the rate of video content streaming

A non-transitory, machine-readable medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:

• identifying a first group of field of vision (FOV) tiles of video content and a first group of out of sight (OOS) tiles of the video content, wherein the first group of FOV tiles are received from a video server over a communication network and encoded using Advanced Video Coding (AVC), wherein the first group of OOS tiles are received from the video server over the communication network and encoded using a first layer of Scalable Video Coding (SVC);
• providing the first group of FOV tiles and the first group of OOS tiles for presentation on a display communicatively coupled to a virtual reality headset;
• detecting a change in a field of vision, wherein the change is one of an actual change in the field of vision or a predicted change in the field of vision;
• identifying a second group of FOV tiles of the video content, wherein the second group of FOV tiles comprises a portion of the first group of OOS tiles;
• identifying a version of the AVC used for the first group of FOV tiles requesting the portion of the first group of OOS tiles;
• receiving the portion of the first group of OOS tiles from the video server over the communication network, wherein the portion of the first group of OOS tiles are encoded using one or more enhancement layers of SVC according to the version of the AVC;
• and
• providing, to the display, the portion of the first group of OOS tiles according to the enhancement layer in conjunction with the providing of the first group of OOS tiles according to the first layer resulting in a high resolution version of the portion of the first group of OOS tiles.

A method, comprising:

• identifying, by a processing system including a processor, a first group of field of vision (FOV) tiles of video content and a first group of out of sight (OOS) tiles of the video content, wherein the first group of FOV tiles are received from a video server over a communication network and encoded using Advanced Video Coding (AVC), wherein the first group of OOS tiles are received from the video server over the communication network and encoded using a first layer of Scalable Video Coding (SVC) according to available bandwidth of the communication network;
• providing, by the processing system, the first group of FOV tiles and the first group of OOS tiles for presentation on a display communicatively coupled to a virtual reality headset;
• detecting, by the processing system, a change in a field of vision, wherein the change is detected using machine learning techniques;
• identifying, by the processing system, a second group of FOV tiles of the video content, wherein the second group of FOV tiles comprises a portion of the first group of OOS tiles;
• receiving, by the processing system, the portion of the first group of OOS tiles from the video server over the communication network, wherein the portion of the first group of OOS tiles are encoded using an enhancement layer of SVC;
• and
• providing, by the processing system, to the display, the portion of the first group of OOS tiles according to the enhancement layer in conjunction with the providing of the first group of OOS tiles according to the first layer resulting in a high resolution version of the portion of the first group of OOS tiles.
