Abstract: A transform block processing procedure wherein a maximum coding-block size and a maximum transform-block size for an unencoded video frame is determined. The unencoded video frame is divided into a plurality of coding-blocks including a first coding block and the first coding block is divided into at least one prediction block and a plurality of transform blocks. The size of the transform blocks depend at least in part on the size of the coding block and the corresponding prediction blocks. The transform blocks are then encoded, thereby generating a video data payload of an encoded bit-stream. A frame header of the encoded bit-stream, including a maximum coding-block-size flag and a maximum-transform-block-size flag, is generated.

Abstract: Summarization segments of an encoded video can be efficiently identified, without the need to decode the encoded video to obtain image data, by analyzing encoded-buffer-size deltas, each indicating an encoded-buffer-size difference between a pair of intra-coded frames of an encoded video.

Abstract: To synchronize data between a remote database and a local object-graph-and-persistence-framework, a synchronization framework receives messages from the local object-graph-and-persistence-framework indicating that a locally-managed object has been retrieved from a local datastore and instantiated or that the locally-managed object has been created, modified, or deleted. When the synchronization framework determines that the message was instigated by a local user's activity (as opposed to a background synchronization process), the synchronization framework synchronizes the locally-managed object with the remote database.

Abstract: A layered media stream may be distributed via a managed server and a peer-to-peer (P2P) network. At least one base layer typically provides a lower-quality media stream, while one or more enhancement layers provide improvements to the media stream. A managed server may provide a base layer to clients. The managed server may also provide enhancement layers through the P2P network. The availability of the enhancement layers may provide clients with an incentive to participate in the P2P network. In some cases, when demand for the media stream is low, the managed server may provide all layers to clients in a traditional client-server network model. When demand for the media stream is high, the managed server may provide only the base layer, making enhancement layers available via the P2P network.

Abstract: Compression of audio signal data is described herein. In various embodiments, the compression of each unit of the audio signal data includes the employment of a distribution substantially representative of a subblock of residual data of the unit of audio signal data, to reduce the amount of data having to be transmitted to transmit the unit of audio signal data to a recipient.

Abstract: A proxy server manages media-data traffic in a network by leveraging the logical separation between the playlist and media segments in modern adaptive streaming protocols to redefine a media stream from an end client's perspective. In various embodiments, the media stream can be redefined from the client's perspective by dynamically modifying the playlist before the playlist is received by the end client and/or by dynamically modifying requests for media segments before the requests are forwarded to a media-origin server.

Abstract: A layered media stream comprising media information layers of different priorities may be adaptively distributed by transmitting at least one of the media information layers to a client on a time-windowed basis. A client device obtains different media information layers during various time windows, and different portions of the media stream may be rendered using different combinations of layers obtained in each time window. In various embodiments, different layers may be obtained from different hosting devices using differing distribution models.
