Active network support on adaptive virtual reality video transmission

Abstract

Aspects of the subject disclosure may include, for example, a method comprising: obtaining media content, such as video; receiving a request from a user and/or user equipment (UE) to view the media content; identifying a predicted field of view of the user; sending the predicted field of view to the equipment of the user at a normal priority; monitoring a line of sight (or actual field of view) of the user; determining a field of view error as a difference between the line of sight and the predicted field of view; and sending the field of view error to the equipment of the user at a higher priority. Other embodiments are disclosed.

What is claimed is: 
     
         1 . A method comprising:
 determining, by a processing system having a processor, an amount of overlap of a line of sight of a user and a predicted field of view of the user;   based on the amount of overlap having a first value, sending, by the processing system, an enhancement layer corresponding to the predicted field of view to equipment of the user, the enhancement layer associated with a media content; and   based on the amount of overlap having a second value that is less than the first value, sending, by the processing system, a base layer corresponding to the line of sight to the equipment at a first priority and the enhancement layer to the equipment at a second priority, wherein the base layer is associated with the media content, and wherein the second priority is based on: a network condition, a first quality of service profile for the user, a second quality of service profile for the media content, or any combination thereof.   
     
     
         2 . The method of  claim 1 , wherein when the amount of overlap has the first value, the sending of the enhancement layer occurs at a third priority that is a lower priority than each of the first priority and the second priority. 
     
     
         3 . The method of  claim 1 , wherein the second priority is a lower priority than the first priority. 
     
     
         4 . The method of  claim 1 , wherein the second priority is based on the network condition, the first quality of service profile for the user, and the second quality of service profile for the media content. 
     
     
         5 . The method of  claim 1 , wherein the predicted field of view is less than 180 degrees. 
     
     
         6 . The method of  claim 1 , wherein the sending of the base layer at the first priority and the enhancement layer at the second priority dedicates a predetermined bandwidth to a field of view error to a detriment of network traffic. 
     
     
         7 . The method of  claim 6 , wherein the field of view error is a difference between the line of sight and the predicted field of view. 
     
     
         8 . The method of  claim 1 , wherein the media content includes virtual reality media content. 
     
     
         9 . The method of  claim 8 , wherein the equipment includes a virtual reality client device. 
     
     
         10 . The method of  claim 1 , wherein the sending of the base layer at the first priority and the enhancement layer at the second priority causes a delay in network traffic. 
     
     
         11 . The method of  claim 1 , wherein the sending of the base layer at the first priority and the enhancement layer at the second priority uses bandwidth dedicated to potential field of view error. 
     
     
         12 . A device, comprising:
 a processing system including a processor; and   a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising:
 based on an amount of overlap between a line of sight of a user and a predicted field of view of the user having a first value, sending an enhancement layer corresponding to the predicted field of view to equipment of the user, the enhancement layer associated with a media content; and 
 based on the amount of overlap having a second value that is less than the first value, sending, by the processing system, a base layer corresponding to the line of sight to the equipment at a first priority and the enhancement layer to the equipment at a second priority, wherein the base layer is associated with the media content, and wherein the second priority is based on: a network condition, a first quality of service profile for the user, a second quality of service profile for the media content, or any combination thereof. 
   
     
     
         13 . The device of  claim 12 , wherein when the amount of overlap has the first value, the sending of the enhancement layer occurs at a third priority that is a lower priority than each of the first priority and the second priority. 
     
     
         14 . The device of  claim 12 , wherein the second priority is a lower priority than the first priority. 
     
     
         15 . The device of  claim 12 , wherein the second priority is based on at least two of: the network condition, the first quality of service profile for the user, or the second quality of service profile for the media content. 
     
     
         16 . The device of  claim 12 , wherein the predicted field of view is less than 180 degrees. 
     
     
         17 . The device of  claim 12 , wherein the sending of the base layer at the first priority dedicates a predetermined bandwidth to a field of view error corresponding to a difference between the line of sight and the predicted field of view to a detriment of network traffic. 
     
     
         18 . 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:
 based on an amount of overlap between a line of sight of a user and a predicted field of view of the user having a first value, sending an enhancement layer corresponding to the predicted field of view to equipment of the user, the enhancement layer associated with a media content; and   based on the amount of overlap having a second value that is less than the first value, sending, by the processing system, a base layer corresponding to the line of sight to the equipment at a first priority and the enhancement layer to the equipment at a second priority that is less than the first priority, wherein the base layer is associated with the media content.   
     
     
         19 . The non-transitory machine-readable medium of  claim 18 , wherein when the amount of overlap has the first value, the sending of the enhancement layer occurs at a third priority that is different from each of the first priority and the second priority. 
     
     
         20 . The non-transitory machine-readable medium of  claim 19 , wherein the third priority is lower than each of the first priority and the second priority.
