Abstract
Presentation of content from a computer or other device on a large screen, such as a projector or a television, is a common activity. The computer is connected to the large screen via a wired or a wireless connection. The content to be presented can include documents and presentation slides with static content such as text and graphics, or content that includes motion such as videos. Default encoders that target high frame rates do not account for content type. The content of a document or slide may appear blurry or include undesirable artifacts if presented at a high frame rate. If the default encoder is configured with a low frame rate, videos may appear jerky and unpleasant to view.
This disclosure describes techniques to select an appropriate content presentation mode that targets a suitable frame rate. The selection is based on encoder statistics, e.g., the percentage of blocks that change in successive frames of the video content from the computer. The selected mode uses a suitable framerate based on the type of content for display on the large screen.
