    • The invention is related to prediction of a lost or damaged block of an enhanced spatial layer frame.A method for predicting a lost or damaged block of an enhanced spatial layer frame comprises the steps of determining an adjuvant frame in the enhanced spatial layer by help of reference information from a lower spatial layer frame corresponding said enhanced spatial layer frame, generating an information reduced block by help of said adjuvant frame and predicting the lost or damaged block by help of the information reduced block.The reference information of the corresponding lower spatial layer frame can be decoded independently from any lower spatial layer reference frame and the adjuvant enhanced spatial layer frame is already decoded. Thus, the computational effort is reduced. By generation of the information reduced block the prediction is made smoother which makes it less vivid and therefore less salient to a user.
    • 本发明涉及增强空间层框架的丢失或损坏块的预测。 一种用于预测增强空间层帧的丢失或损坏的块的方法包括以下步骤:借助来自对应于所述增强空间层帧的较低空间层帧的参考信息来确定增强空间层中的辅助帧,生成减少的信息 通过所述辅助帧的帮助来阻止并且通过信息减少块的帮助来预测丢失或损坏的块。 相应的较低空间层帧的参考信息可以独立于任何较低空间层参考帧进行解码,并且辅助增强空间层帧已被解码。 因此,减少了计算量。 通过生成信息减少块,使预测变得更平滑,这使得它不那么生动,因此对于用户来说不那么显着。

    • In the case of packet loss during transmission over an error-prone transmission channel, some decoders may perform error concealment. In real-time systems, application decoders must handle the data loss alone and find out which data are missing. A special syntax within a packet-based framework is provided which is based on identifying and indicating the relationship between RTP packets and the application layer data they carry, before the packets are fed to the multi-layer application decoder. This helps the decoder to employ proper error concealment techniques in time, and prevents unnecessary processing in the decoder. A data stream comprises RTP packets containing application data of a multi-layer application, wherein an RTP packet (p2) contains two kinds of application layer information (NBf, NBn): one relating to the next RTP packet (p3), and one relating to the previous RTP packet (p1). In case of packet loss, the decoder can immediately determine the amount and type (VCLx) of missing data.
    • 在通过易错传输信道传输过程中丢包的情况下,某些解码器可能会执行错误隐藏。 在实时系统中,应用解码器必须单独处理数据丢失,并找出哪些数据丢失。 提供了基于分组的框架内的特殊语法,其基于在分组被馈送到多层应用解码器之前,基于识别并指示RTP分组与它们携带的应用层数据之间的关系。 这有助于解码器及时采用适当的错误隐藏技术,并防止解码器中的不必要的处理。 数据流包括包含多层应用的应用数据的RTP分组,其中RTP分组(p2)包含两种应用层信息(NBf,NBn):一个与下一个RTP分组(p3)有关,一个与 到先前的RTP分组(p1)。 在丢包的情况下,解码器可以立即确定丢失数据的数量和类型(VCLx)。
