Abstract
Embodiments of apparatuses and methods to decrease a size of a memory in a low-latency video communication system are described. A control unit is configured to monitor a condition associated with at the communication link. The control unit is configured to receive the video content over a link based on monitoring. A memory comprising a full-frame buffer is coupled to the control unit. The full-frame buffer is configured as a history buffer to store a full frame of the video in a coding format that matches the coding format of the video content received over the link. A display unit is coupled to the history buffer. A portion of the full-frame buffer is configured as a network streaming buffer.
