Abstract: Edge-based interpolation for upsampling. One method may include determining an edge characteristic associated with an interpolation point, the edge characteristic having an edge magnitude and an edge angle; selecting an interpolation filter in response to the edge angle; and determining a pixel value at the interpolation point using the selected interpolation filter. Other embodiments include edge-based interpolation followed by an adaptive sharpening filter. The sharpening filter is controlled by the edge-based interpolation parameters that determine the pixels to be sharpened and the sharpening strength.

Abstract: Systems and methods are described for determining an optimised sampling ratio for coding video data that reduces overall distortion introduced by the coding process. It seeks to balance the information loss introduced during downsampling and the information loss introduced during coding. The sampling ratio is generally determined by reducing, or in some cases minimizing, the overall error introduced through the downsampling process and the coding process, and may be adaptive based on the content of the video data being processed and a target bit rate. Computation power can be saved by coding a downsampled video. The process derives a plurality of downsampling ratios, and selects a downsampling ratio that reduces the total amount of distortion introduced during the down - sampling and coding stages. The down - sampling ratio may be selected given the available data transmission capacity, input video signal statistics, and/or other operational parameters, and may optimally reduce the overall distortion.

Abstract translation: 描述了用于确定用于编码视频数据的优化采样率的系统和方法，其减少由编码过程引入的整体失真。 它寻求平衡在下采样期间引入的信息丢失和编码期间引入的信息丢失。 采样率通常通过减小或在一些情况下最小化通过下采样处理和编码处理引入的总体误差来确定，并且可以基于正在处理的视频数据的内容和目标比特率来自适应。 可以通过对下采样视频进行编码来节省计算功率。 该过程导出多个下采样比，并且选择降低在下采样和编码阶段期间引入的失真总量的下采样比。 给定可用数据传输容量，输入视频信号统计和/或其他操作参数可以选择下采样比，并且可以最佳地降低整体失真。

Abstract: A communication system extends IETF Session Initiation Protocol (SIP) signaling used by IMS architecture. As a basic use case, initially a first user equipment (UE1) (controller) is in a media session (e.g., audio, video and message session) with a remote UE. To transfer provider of one media component to a controllee UE, the controller UE1 sends a REFER message with a relevant body to trigger the media session operations to a Service Centralization and Continuity Application Server (SCC AS). The SCC AS is able to interpret the contents of the REFER message to perform the media session manipulation on one or multiple UEs (originating UE itself or other UEs). The innovation provides for a REFER message that convey what needs to be done in a separate SIP header carrying target dialog and media line number(s), in a SDP body that REFER carries, or XML body that will be in REFER.

Abstract: A communication network's bandwidth may be managed using bandwidth management ("BWM") and/or bandwidth aggregation ("BWA") techniques. For example, packets of traffic may be inspected to identify a video stream and/or video sub-streams. The video sub-streams may be partitioned for transmission. For example, the video sub-streams may be partitioned based on a characteristic and/or policies associated therewith. One or more radio access technologies ("RATs") may be selected for transmitting the video sub-streams. The one or more RATs may be selected according to one or more policies for managing the bandwidth associated with the video. The video sub-streams may be transmitted via a single RAT or a plurality of aggregated RATs.

Abstract: A method and apparatus for automatically discovering and retrieving content based on a content identity (ID) are disclosed. User agents and content control entities in the network interact for registering the content, discovering the content hosts and sources, and initiating and controlling the content session. A content name resolution handler (CNRH) is provided for mapping content IDs to network locations or addresses. Two or more content service provider networks may interconnect each other to discover and retrieve the content. A content request from a client device includes a content ID that uniquely identifies a content object. The content ID is resolved with a CNRH to obtain identity information of at least one content provider for serving the content request, and the content request is forwarded to the selected content provider. The content request may be routed to the selected content provider via IP multimedia subsystem (IMS) control plane entities.
