Abstract: A wireless display subsystem includes a hardware composition generator, a hardware video encoder, and a wireless hardware transport stream multiplexer. The hardware composition generator reads video data from a memory device and generates video frame data by synthesizing the video data. The hardware video encoder receives the video frame data in an on-the-fly (OTF) manner from the hardware composition generator and generates a video stream by encoding the video frame data. The wireless hardware transport stream multiplexer receives the video stream in the OTF manner from the hardware video encoder, reads an audio stream from the memory device, multiplexes the video stream and the audio stream, and generates a wireless display packet by packetizing the multiplexed video and audio streams.

Abstract: A display controller includes a scaler which is configured to receive a frame image, scale up the frame image to generate a high resolution frame image based on a quality of the frame image and information about a display device, and output the frame image or the high resolution frame image to the display device for display. A method of controlling image display includes: receiving a frame image; determining whether to scale up the frame image to generate a high resolution frame image based on a quality of the frame image and information about a display device; scaling up the frame image according to a result of the determining; and outputting the frame image or the high resolution frame image for display at the display device.
