    Abstract: Techniques for delivering content, such as videos, over a network are described. A core server and an edge server are provided. The core server has local storage. The edge server has local storage. A set of video frames is partitioned into a first group and a second group. Video frames in the first group are encoded into a scalable encoded stream. The scalable encoded stream is sent to the local storage at the edge server. The second group of video frames is encoded into a set of supplemental encoded streams using the scalable encoded stream as a reference. The supplemental encoded streams are encoded such that the bit rate and/or resolution of any two supplemental encoded streams is different. The set of supplemental encoded streams is stored in the storage of the core server.

    Abstract: Disclosed herein are methods and apparatuses for selective prediction signal filtering. One aspect of the disclosed implementations is a method for encoding a frame of a video stream including determining a first performance measurement for a first set of prediction samples identified for a group of pixels using a first prediction mode, generating a filtered set of prediction samples by applying a filter to a second set of prediction samples, wherein at least one of the filtered set of prediction samples or the second set of prediction samples are identified using a second prediction mode, determining a second performance measurement for the filtered set of prediction samples, generating, using a processor, a residual based on the filtered set of prediction samples and the group of pixels if the second performance measurement exceeds the first performance measurement, and encoding the frame using the residual.
