Abstract: An information stream organized as a sequence of blocks is encoded according to a graceful degradation principle. The stream poses temporal non-uniform data processing requirements. In particular, with respect to a received block one or more blockwise defined control parameters and an associated blockwise processing load are detected (44). Under control (46) of a processing load for one or more previous blocks, one or more later blocks before processing thereof get an adjustment (48) of one or more of the control parameters. This lowers an expected load for the later block in case of an excessive load, and vice versa when detecting a sub-standard load.

Abstract translation: 根据优雅的降级原理对作为块序列组织的信息流进行编码。 流提供了时间不均匀的数据处理要求。 特别地，对于接收到的块，检测到一个或多个块状定义的控制参数和相关联的块状处理负载（44）。 在一个或多个先前块的处理负载的控制（46）下，在处理之前的一个或多个稍后的块获得一个或多个控制参数的调整（48）。 这会在过载时降低后期块的预期负载，反之亦然。

Abstract: A method and device for recording video on a record carrier (11), e.g. an optical disc. The information is arranged according to a recording format, e.g. DVD-video, for being playable in standardized players. The video information is subdivided into cells and playback parameters for reproducing sequences of the cells are included in control information. The format prescribes that within the recording area the control information precedes the video information for playback functions of the recorded video. However for home recording it is preferable that a recording is made in one pass, i.e. the video is to be recorded directly at its final location. Therefore the recorder has a control unit (20) for performing the following steps: first creating a free area (12) by selecting a starting point (13) within the recording area different from the beginning of the recording area, thereafter recording the real-time information from the starting point (13), and recording the control information in said free area (12).

Abstract translation: 一种用于在记录载体（11）上记录视频的方法和装置，例如。 光盘。 信息根据记录格式进行排列。 DVD视频，可在标准播放器中播放。 视频信息被细分为单元，并且用于再现单元的序列的播放参数包括在控制信息中。 该格式规定在记录区域内，控制信息在记录视频的回放功能的视频信息之前。 然而，对于家庭记录，优选的是一次进行记录，即视频直接记录在其最终位置。 因此，记录器具有用于执行以下步骤的控制单元（20）：首先通过选择与记录区域的开始不同的记录区域内的起始点（13）来创建空闲区域（12） 来自起点（13）的时间信息，并将控制信息记录在所述空闲区域（12）中。

Abstract: A processing device comprises an instruction memory 120 for storing virtual machine instructions, such as Java byte codes. A processor 112 of the processing device comprises a predetermined microcontroller core 114 for executing native instructions from a predetermined set of microcontroller specific instructions. The native instructions differ from the virtual machine instructions. The processor 112 is of a type which may request re-feeding of a plurality of native instructions. For instance, the processor 112 may have a pipeline and/or instruction cache which after an interrupt need to be re-filled. The processing device comprises a pre-processor 130 with a converter 132 for converting at least one virtual machine instruction, fetched from the instruction memory, into at least one native instruction. Feeding means 136 of the pre-processor 130feed native instructions to the microcontroller core 114 and re-feed native instructions in response to the processor requesting re-feeding of a number of native instructions.

Abstract: Audio-centered information is stored on a unitary medium by using a Table-of-Contents (TOC) mechanism that specifies an actual configuration of various audio items on the medium. In particular, each one of a set of one or more Track Areas gets at least two mutually logically conforming Sub-TOCs assigned. This allows to retrieve any constituent Sub-TOC part from at least any correct copy of the Sub-TOCs. Furthermore, one or more Master-TOCs are provided for specifically pointing to each of the Sub-TOCs.

Abstract: In a transmission system a signal to be transmitted is applied to a source encoder (4) for being encoded. The encoded signal is applied to a channel encoder (6) which applies an error correcting code on the encoded input signal. The output signal of the channel encoder (6) is transmitted to a receiver (14) which processes the received signal by means of a channel decoder (18) and a source decoder (20). The source encoder comprises a codebook entry selector (42) which selects a ternary number generated by a ternary generator (26), such that a synthetic signal derived from said ternary number is a best approximation of a signal to be encoded. The ternary value found in this way is converted into a binary number in such a way that the ternary values corresponding to binary numbers which differ only in one particular digit, differ only in one single digit. This has the advantage that a transmission error of in said particular digit has a small perceptual effect, because the corresponding ternary number differ only slightly. In a preferred embodiment the numerical value of a first codebook entry corresponds to an index of a second codebook entry, and the numerical value of the second codebook entry corresponds to the index of the first codebook entry.

Abstract: The variable bitrate coding method according to the invention comprises an iterative process including a first analysis pass and a second prediction pass. The analysis pass allows for a picture coding of a sequence with a constant quantization stepsize (and quality) and the prediction pass allows for a matching of the stepsize to the wanted target bitrate. After some iterations, a last step allows for a finer adjustment of said stepsize with respect to said target bitrate. Application: MPEG-2 encoders for storage media with limited capacity.

Abstract: Objects of a three dimensional (3D) virtual world that are represented on a two dimensional (2D) image plane are provided with labels which are generated in the 2D image plane itself. The labels are in spatial registration with the object as represented on the 2D image plane. The generation of the labels in the 2D image plane avoids problems relating to perspective and aliasing which can occur when labels are provided in the virtual world itself and are rendered from the 3D virtual world.

Abstract translation: 在二维（2D）图像平面上表示的三维（3D）虚拟世界的对象被提供有在2D图像平面本身中生成的标签。 标签与2D图像平面上的对象进行空间对齐。 在2D图像平面中生成标签避免了与透视和混叠有关的问题，这些问题可能在虚拟世界本身提供标签并从3D虚拟世界呈现时发生。
