摘要： 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).

摘要： A multimedia provider (100) generates, based on a request for a media channel from a user terminal (10), a session set-up description that is returned to the user terminal (10). The description defines, when processed in the terminal (10), a session window (20) that is displayed on a screen (12) of the terminal and comprises a region (22) for displaying media data of a requested channel and a channel region (24) comprising information on alternative available media channels. The description also defines a binding between user inputs (14) of the terminal (10) and identifiers of the alternative channels. The set-up description allows for a user-friendly channel switch by automatically transmitting a channel switch request to the multimedia provider (100) upon a triggering of the user input (14) that is associated with the identifier of the requested media channel. The description, thus, provides a visually appealing graphical interface and simultaneously allows for a user-friendly media channel switch.
摘要翻译：多媒体提供者（100）根据来自用户终端（10）的对媒体频道的请求生成返回给用户终端（10）的会话建立说明。该描述定义了在终端（10）中处理的会话窗口（20），其显示在终端的屏幕（12）上，并且包括用于显示所请求的频道的媒体数据的区域（22）和信道区域（24）包括关于替代可用媒体信道的信息。该描述还定义了终端（10）的用户输入（14）和替代频道的标识符之间的绑定。所述设置描述允许在触发与所请求的媒体信道的标识符相关联的用户输入（14）时，自动向多媒体提供商（100）发送频道切换请求，从而进行用户友好的频道切换。因此，该描述提供了视觉吸引人的图形界面，同时允许用户友好的媒体频道切换。

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

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

摘要： An improved forward error correction (FEC) technique for coding speech data provides an encoder module which primary-encodes an input speech signal using a primary synthesis model to produce primary-encoded data, and redundant-encodes the input speech signal using a redundant synthesis model to produce redundant-encoded data. A packetizer combines the primary-encoded data and the redundant-encoded data into a series of packets and transmits the packets over a packet-based network, such as an Internet Protocol (IP) network. A decoding module primary-decodes the packets using the primary synthesis model, and redundant-decodes the packets using the redundant synthesis model. The technique provides interaction between the primary synthesis model and the redundant synthesis model during and after decoding to improve the quality of a synthesized output speech signal. Such “interaction,” for instance, may take the form of updating states in one model using the other model.
摘要翻译：用于编码语音数据的改进的前向纠错（FEC）技术提供了一种编码器模块，其使用主要合成模型对输入语音信号进行一次编码以产生初始编码数据，并且使用冗余合成模型对输入语音信号进行冗余编码以产生冗余编码数据。分组器将主编码数据和冗余编码数据组合成一系列分组，并通过诸如因特网协议（IP）网络的基于分组的网络传送分组。解码模块使用主合成模型对分组进行主要解码，并使用冗余合成模型对分组进行冗余解码。该技术在解码期间和之后提供主要合成模型和冗余合成模型之间的交互以提高合成输出语音信号的质量。例如，这种“交互”可以采用其他模型在一个模型中更新状态的形式。
