Abstract: A method for efficient frame loss recovery and reconstruction (EFLRR) in a dyadic hierarchy is described herein. The method includes obtaining a current frame of a group of pictures. The method also includes calculating a Dyadic Hierarchy Picture Index difference based on a layer information in response to a prior frame missing in the group of pictures. Finally, the method includes decoding the current frame in response to a determined frame continuity based on the Dyadic Hierarchy Picture Index difference.

Abstract: Embodiments include apparatuses, methods, and systems including a content scenario detection unit and a rate adjustment unit for the communication of a multimedia content. The multimedia content may include a low bitrate scenario and a high bitrate scenario. The content scenario detection unit may detect the low bitrate scenario of the multimedia content for a multimedia traffic when a transmitter is to generate a first window of one or more frames of the low bitrate scenario during a first time period at a first encoding rate. The rate adjustment unit may determine, based at least in part on the detection of the low bitrate scenario, a second encoding rate different from the first encoding rate. The transmitter may generate at the second encoding rate a second window of one or more frames of the low bitrate scenario during a second time period. Other embodiments may also be described and claimed.
