Abstract: A method includes receiving, at a device, a plurality of image frames corresponding to a video stream. The plurality of image frames include a first image frame having a first resolution and a second image frame having a second resolution that is lower than the first resolution. The method also includes detecting, at the device, a trigger by analyzing the second image frame. The method further includes designating, at the device, the first image frame as an action frame based on the trigger.
Abstract translation: 一种方法包括在设备处接收对应于视频流的多个图像帧。 多个图像帧包括具有第一分辨率的第一图像帧和具有低于第一分辨率的第二分辨率的第二图像帧。 该方法还包括在设备处通过分析第二图像帧来检测触发。 该方法还包括在设备处指定基于触发的作为动作帧的第一图像帧。

Abstract: In one example, a device for retrieving video data includes a display interface coupled to a display, a memory configured to store video data, and one or more processors configured to determine a plurality of regions of video data to be displayed via the display, retrieve video data having a first quality for a first subset of the plurality of regions at which a visual focus of a user is directed, retrieve video data having a second quality for a second subset of the plurality of regions that neighbor the first subset of the plurality of regions, wherein the second quality is lower than the first quality, and retrieve video data having a third quality for a third subset of the plurality of regions that is outside the first subset and the second subset, wherein the third quality is lower than the second quality.
