摘要： Methods and arrangements in a client node and a server node for supporting a decision on decoding and playout of a certain content in the client node. The methods and arrangements relate to the determining, conveying and obtaining of information related to the characteristics (level) required for decoding and playing out the certain media content at a non-regular playout rate. The method and arrangement in the client node further relate to determining, based on the obtained information, which playout rate(s) that is/are supported by the client node in regard of level. The methods and arrangements enable the client node to refrain from decoding and playout of the content at a non-regular rate requiring a level which is not supported by the client node.

摘要： Supplemental processing information (52, 54) defining post-decoding instructions for processing decoded media content is co-organized in a file (1) together with a pseudo-identifier of a media codec employed for encoding the media content. The co-organization trigger abortion of decoding of the media content by a legacy media terminal (210) that does not recognize the pseudo-identifier but enables decoding of the media content by a media terminal (200) that recognizes the pseudo-identifier to thereby enable post-decoding processing of the decoded media content using the supplemental processing information (52, 54). The co-organization thereby prevents legacy media terminals (210) that cannot use the supplemental processing information from decoding the media content and rendering the media content in a media presentation.

摘要： Multi-view media data is generated by providing encoded media data representative of multiple media views of a media content. Each of the media views (22-28) is associated with a structural priority identifier (36) indicative of an encoding inter-relationship of the media data relative media data of at least another media view(24-28). A content priority identifier (38) is determined for preferably each media view(22-28). The content priority identifier (38) is, in contrast to the structural priority identifier(36), indicative of the rendering importance level of the media data of the media view(22-28). The determination and inclusion of the content priority identifiers(38)provides an improved processing of the media data, for instance in connection with a selective pruning, rendering, and/or protection application of the multi-view media data.
摘要翻译：通过提供表示媒体内容的多个媒体视图的编码媒体数据来生成多视图媒体数据。每个媒体视图（22-28）与指示至少另一媒体视图（24-28）的媒体数据相对媒体数据的编码相互关系的结构优先级标识符（36）相关联。为优选地每个媒体视图（22-28）确定内容优先级标识符（38）。与结构优先级标识符（36）相反，内容优先级标识符（38）指示媒体视图的媒体数据的渲染重要性级别（22-28）。内容优先级标识符（38）的确定和包括提供媒体数据的改进处理，例如结合多视图媒体数据的选择性修剪，呈现和/或保护应用。

摘要： Metadata defining decoding and rendering instructions for media content to be co-rendered in a media presentation is divided and distributed as track fragments (15, 16) provided in different media container files (11). Track fragment adjustment information (20) is included in at least one such track fragment (15) in order to define rendering timing relationships between media content portions defined by the track fragments (15, 16) in a current media container file (11). The rendering timing relationships enable a correct time alignment of the playback of the media content to be co-rendered to achieve a synchronized media presentation. The track fragment adjustment information (20) is particularly advantageous in connection with tuning in or a random access in a stream of media container files (1, 11) comprising fragmented metadata.

摘要： Methods and arrangements in video handling entities for transforming an MVC bit stream to an AVC bit stream and vice versa. The methods and arrangements involve modification of reference data in an obtained bit stream and thus transforming the bit stream into another format. The suggested solution is a low complexity procedure, and thus much faster than e.g. transcoding of a bit stream into another format.
