VIDEO ENCODING BASED ON AREAS OF INTEREST

摘要

Content may have associated interest information that indicates various areas of interest within images displayed during presentation of the content. An area of interest is an area for which a different encoding bitrate may be desired relative to another area. When an image is encoded for transmission, instructions may be provided to an encoding component for encoding of the image based on the associated interest information. The encoding component may then determine appropriate bitrates for different portions of the image based on the interest information while also satisfying overall bitrate constraints for the image as a whole.

1. One or more compute nodes having stored therein instructions that, upon execution by the one or more compute nodes, cause the or more compute nodes to perform operations comprising:
receiving a command to initiate streaming delivery of a video game, the video game including data corresponding to three-dimensional scenes that are used to render two-dimensional images for display, the video game also having associated interest information that indicates areas within the rendered two-dimensional images, wherein each indicated area is an area within a two-dimensional image for which a different encoding bitrate is desired relative to another area of the same two-dimensional image; rendering a first two-dimensional image based on a first portion of the data included in the video game corresponding to a first three-dimensional scene; encoding the rendered two-dimensional image based on a first portion of the interest information corresponding to the first two-dimensional image, wherein the first portion of the interest information indicates a first area within the first two-dimensional image and provides instructions for encoding the first area at a different bitrate relative to a second area of the first two-dimensional image; and transmitting the encoded first two-dimensional image to a destination.
