Abstract: A method in an encoder, the method comprising: receiving a video; encoding a segment of the video at different bit rates to generate multiple representations of the segment at different bit rates; generating a quality metric for each representation of the video segment; and storing the lowest bit rate representation of the video segment for which the respective quality metric meets a predefined minimum quality threshold.

Abstract: A system and method for mitigating motion artifacts in a media streaming network, wherein a scheme for facilitating adaptive post-decode (PD) filtering at a client device is provided. Extraction of still area grid information is effectuated at a source media processing node. Extracted still area grid information is multiplexed with audio/video components for appropriately signaling to downstream devices based on media containerization deployed for distribution. A client device is operative to select a suitable PD filter based on a plurality of selection criteria and apply the selected PD filter to the still area grids of the decoded image frames.

Abstract: Media content comprises video. The video comprises a sequence of scenes comprising pictures. The media content comprises segments. A method determines when a scene change between a first scene and a second, subsequent, scene occurs within a predetermined proximity to a boundary between segments. When a scene change occurs within a predetermined proximity of an end of a segment, at least a first picture in the second scene is discarded and an additional picture is inserted in the first scene. When a scene change occurs within a predetermined proximity of a start of a segment, at least one picture in the first scene is discarded and an additional picture is inserted in the second scene. The additional picture can be a repeat or a copy of an existing picture, or it can be based on at least one existing picture in the first scene, such as by interpolation.
