摘要： In an image processing method, an object is located within an image. An area around the object is determined and divided into at least first and second portions based upon image information within the area. The object can then be classified based upon both image information in the first portion of the area and image information in the second portion of the area.

摘要： A video server comprises memory to store video content obtained from multiple camera views; one or more streaming components configured to stream video content to a client application; and one or more frame feeder components. A frame feeder component is configured to access first video content corresponding to a first camera view and provide the first video content to a streaming component; access, in response to a request received at the video server to stream second video content corresponding to a second camera view, intermediate video content corresponding to one or more camera views intermediate to the first and second camera views; and access the second video content, and provide the intermediate video content and the second intermediate video to the streaming component.

摘要： In one embodiment, a method of organizing multimedia content includes obtaining, by a server, a first video program. Also, the method includes selecting a first video, where the first video is a first subset of the first video program, and where the first video forms a first branch of the first video program and selecting a second video, where the second video is a second subset of the first video program. Additionally, the method includes selecting a first partial video, where the first partial video is a first subset of the first video and selecting a second partial video, where the second partial video is a second subset of the first video. The method also includes establishing a multi-dimensional index tree including a first video program level, a first video level, a first partial video level.

摘要： Embodiments are provided for a cloud-based reliable media ingestion and transcoding. The embodiments comprise an improved backup mechanism where each worker node, such as a virtual machine, physical machine, workstation, or server, in a cloud or Internet environment handles one streamed media/video channel transcoding and another streamed media/video channel ingestion backup. To reduce ingestion storage demands, the ingestion backup storage is based on a pre-determined relatively short-term sliding window. When an ingestion and transcoding worker node fails, a new worker node is brought up to take over from the failed worker node the live transcoding task of a first channel and the ingestion backup task of a second channel. Additionally, the new worker node retrieves backup data for the first channel from a third worker node and a central media storage to ensure seamlessly uninterrupted live ingestion and transcoding of the first channel, and continues the ingestion backup task of the second channel.

摘要： In accordance with an embodiment, a method includes electronically receiving a media presentation description (MPD) from a network. The MPD describes multimedia content that includes alternative representations of a plurality of media types, and the MPD includes information indicative of how the alternative representations are encoded. The method also includes selecting one of the plurality of alternative representations for at least one of the plurality of media types based on information included in the MPD, requesting the selected one of the plurality of alternative representations piece-by-piece, and electronically receiving a piece of media data.
