Abstract: A stream (1) of media frames (12-16, 22-26, 32-36) is generated by providing multiple media frames (22-26) having respective assigned default timestamps (40) defining rendering times of the media data of the media frames (22-26) according to a default rendering time schedule. Respective alternative timestamps (50) are assigned to at least a portion of the media frames (22-26). These alternative timestamps (50) define alternative rendering times of the media data of the media frames (22-26) according to an alternative rendering time schedule. The alternative timestamps (50) can be used for providing an efficient media rendering when tuning in to the stream (1) at an intermediate position of a frame grouping (20) of the media frames (22-26) thereby missing some of the media frames (22, 24) of the frame grouping (20).

Abstract translation: 通过提供具有各自分配的默认时间戳（40）的多个媒体帧（22-26）来生成媒体帧（12-16,22-26,32-36）的流（1），所述默认时间戳定义所述媒体帧的媒体数据的渲染时间 媒体帧（22-26）根据默认呈现时间表。 相应的替代时间戳（50）被分配给媒体帧（22-26）的至少一部分。 这些替代时间戳（50）根据替代的呈现时间表来定义媒体帧（22-26）的媒体数据的替代呈现时间。 当在媒体帧（22-26）的帧分组（20）的中间位置调谐到流（1）时，备选时间戳（50）可用于提供有效的媒体呈现，从而缺少一些媒体 帧分组（20）的帧（22,24）。

Abstract: The media session management of the invention encompasses a media server (200) having access to multiple unicast-based media channels and a user terminal (100). The user terminal (100) generates and transmits a generic, channel- transparent session request to the server (200). This request initiates a generic, channel-transparent media session setup procedure between the terminal (100) and the server (200). The setup procedure involves exchange of requests and responses but no media channel is yet selected or notified at the server (200). Once the channel-transparent setup has been completed, the user terminal (100) transmits a channel- specific rendering request for a desired media channel to the server (200). In a subsequent channel switch, the terminal (100) simply transmits a new channel- specific request for a new channel to the server (200) during the ongoing session and reusing the negotiated transport parameters of the channel-transparent setup procedure.

Abstract: One aspect provides a client apparatus and method of adapting the bit-rates of a plurality of media streams transmitted by a client entity in a multi-media conference. The media streams have associated quality levels, at least one of the media streams having a plurality of associated quality levels. A priority value is assigned, on a scale of priority values, to each quality level of each media stream. A list is determined, in order of priority value, comprising all of the assigned priority values and for each assigned priority value specifying the quality levels of the media streams to which the priority value has been assigned. Feedback is obtained for each media stream indicating a QoS for the media stream. Based on the feedback, the bit-rate of one or more of the media streams is adjusted in accordance with the priorities on the list. Another aspect provides a mixer apparatus and method of adapting media streams distributed by a mixer in a multi-media conference.

Abstract: The invention teaches a media container file (1) comprising media data organized into media source blocks (20; 22; 24). The media source blocks (20; 22; 24) are partitioned into source symbols that can be processed by a forward error correction (FEC) algorithm for generation of FEC redundancy data (70). Information (30; 32; 34) of this source block partitioning is included in the file (1) in addition to the source blocks (20; 22; 24). The container file (1) also comprises meta data (40) providing an association between the media source blocks (20; 22; 24) and the partitioning information (30; 32; 34). The container file (1) can be employed by a media server (200) in a media session for compiling media data packets to be transmitted to requesting clients (400; 410; 420) without the need of extensive data processing before calculating FEC data.

Abstract: The invention pertains to a Mixer and a Method for providing media streams towards a plurality of endpoints (EP1, EP2), the media streams originating from one or more media source (SRC). Within the method at least a first request set (COPR1) of a first endpoint (EP1) of said plurality of endpoints and a second request set (COPR2) of a second endpoint (EP2) of said plurality of endpoints are received, whereby a request set comprises information relating to at least a subset of one or more codec parameters, and whereby a request set pertains to a media stream, whereby said first request set and said second request set pertain to a same media content. Said received first request set (COPR1) and said received second request set (COPR2) is aggregated into an aggregated request set (COPRA) pertaining to a first media source (SRC). Thereafter one or more media streams according to said aggregated request set (COPRA) are requested from said first media source (SRC). On receiving said one or more requested media streams from said first media source (SRC), one or more media streams are delivered towards said first endpoint (EP1) according to the first request set (COPR1) and one or more media streams are delivered towards said second endpoint (EP2) according to the second request set (COPR2), whereby portions of said media streams are delivered towards said endpoints according to the respective request set.
