Abstract
One or more system, apparatus, method, and computer readable media is described for improving the quality of static image frames having a relatively long residence time in a frame buffer on a sink device. Where a compressed data channel links a source and sink, the source may encode additional frame data to improve the quality of a static frame presented by a sink display. A display source may encode frame data at a nominal quality and transmit a packetized stream of the compressed frame data. In the absence of a timely frame buffer update, the display source encodes additional information to improve the image quality of the representation of the now static frame. A display sink device presents a first representation of the frame at the nominal image quality, and presents a second representation of the frame at the improved image quality upon subsequently receiving the frame quality improvement data.

21. An image frame display source apparatus, comprising:
-
one or more processors to generate image frames for display; a transmitter coupled to the processors to stream an encoded first representation of a first of the image frames to a display device; and the processors to initiate streaming of additional data encoding the first image frame in the event a second of the image frames is not generated within a predetermined time. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method for improving the quality of a static image presented on a sink display, the method comprising:
-
generating an image frame for display; streaming an encoded first representation of the image frame to a display device; and streaming additional data encoding the image frame in the event a second image frame is not generated within a predetermined time, wherein the additional data encodes information for a second representation of the first image frame having higher quality than that of the first encoded representation. - View Dependent Claims (34, 35, 36, 37)

38. One or more non-transitory computer readable media including instruction stored thereon, which when executed by a processing system, cause one or more processors of the system to perform a method comprising:
-
generating an image frame for display; streaming an encoded first representation of the image frame to a display device; and streaming additional data encoding the image frame in the event a second image frame is not generated within a predetermined time, wherein the additional data encodes information for a second representation of the first image frame having higher quality than that of the first encoded representation. - View Dependent Claims (39, 40)
