Abstract

A system and method are provided for rendering a video stream for display on a display device, which may comprise receiving the video stream by streaming and generating display data defining a visible display area to be displayed by the display device, wherein said generating of the display data comprises rendering the video stream in a sub-area of the visible display area. A selection mechanism may be provided by which a version of the video stream may be selected for streaming having a spatial resolution and/or a bitrate which is selected based on a size of the sub-area. Thereby, the video stream may be adapted in terms of visual quality to the effective spatial resolution provided by the sub-area. In particular, for a smaller sub-area, it may be avoided to stream a version of the video stream which contains spatial detail which cannot be perceived when the video stream is rendered in the sub-area but which may incur more technical cost, e.g., in terms of required network bandwidth, decoding capabilities and decoding resource allocation, etc., than a video stream which has a lower resolution and/or lower bitrate and is thereby adapted to the size of the sub-area.
