摘要： A technique for protecting media content that is to be accessible via multiple media tracks of a media file is provided. A method implementation of this technique comprises the step of providing a set of one or more first layer data items that are to be accessible via a first media track, with each first layer data item being decodable to be rendered as a portion of the media content. Moreover, a set of one or more second layer data items is provided that are to be accessible via at least one second media track, with each second layer data item being decodable to be rendered in combination with at least one decoded first layer data item as an enhanced portion of the media content. With each second layer data item a track reference index is associated that allows to identify the first media track via which the first layer data items are accessible. Then, in a next step, the second layer data items and the associated track reference indices (plus optionally the first layer data items) are encrypted for being transmitted to a content recipient.

摘要： A technique for distributing in a multicasting network media content via two or more media layers is described. The media layers are hierarchically arranged in accordance with a scalable coding protocol such as the Scalable Video Coding (SVC) protocol. In a method implementation of this technique, in a first step a first number of media recipients for a first media layer that is transmitted via a first bearer of the multicasting network is determined. Then, a second bearer of the multicasting network for at least one second media layer is selected taking into account the first number and a hierarchical relationship between the first media layer and the second media layer.

摘要： The embodiments of the present invention relates to a method and a processor for representing a 3D scene. In the method, one 3D component of the 3D scene to be represented, captured at least three different views (v1,v2,v3) is projecting to a predefined view (vF). A value associated with each projected view regarding the 3D component is then determined and consistency among the projected views regarding the 3D component is detected. Moreover, a consistency value regarding the 3D component is determined based on the determined values associated with the respective projected view, and the determined values are replaced by the determined consistency value on at least one of the three projected 3D components.

摘要： A method of indicating bit stream subsets in a video bit stream (210) is provided. The method comprises receiving the bit stream, dividing the bit stream into video packets (211-216), wherein each packet comprises either one of video data or supplemental information, and marking each packet with a single subset identifier (stream_id). Each subset identifier is associated with a corresponding bit stream subset (221-223). Further, a method of extracting video packets from a video bit stream is provided. The method comprises providing relevant subset identifiers, receiving video packets from the bit stream, and, for each received packet, inspecting the subset identifier of the packet. The packet is extracted if the subset identifier matches one of the relevant subset identifiers. This allows condensing properties of a bit stream subset into a single identifier, thereby simplifying the processing of video packets in the network and on the client side. Further, devices corresponding to the aforementioned methods are provided.

摘要： Methods and arrangements for compression and de-compression of N-stream multi-view 3D video in data handling entities, e.g. a data providing node and a data presenting node. The methods and arrangements involve multiplexing (802) of at least some of the N streams of the N-stream multi-view 3D video into one pseudo 2D stream, which appears as a 2D video stream to a 2D encoder. Further, the pseudo 2D stream is provided (804) to a replaceable 2D encoder, for encoding of the pseudo 2D stream, resulting in encoded data having a 2D codec format. This codec-agnostic modular approach to 3D compression and de-compression ensures a fast and convenient access to flexible virtual 3D codecs for handling of N-stream multi-view 3D video.
