摘要： The invention is related to a method of transmitting data from a transmitter to a receiver, in particular in a DVB-scenario. Hereby data is transmitted in consecutive bursts and each burst comprises a plurality of Multi-Protocol Encapsulation (MPE) and Multi-Protocol Encapsulation - inter-burst-Forward Error Correction (MPE-iFEC) sections, whereby MPE-sections carry an ADST-address containing the position in the Application Data Sub-Table (ADST) into which the content of the respective MPE-section has to be written. This ADST-address and/or the status of each byte is stored into the ADST while mapping the content of a burst in the ADST and iFDST, whereby the status of each byte is marked as "error free" or "with errors". This ADST-address and/or the byte status is further written in the ADT's while mapping the content of the ADST into ADT's, so that the ADST-address and/or the byte status is conveyed from the ADST to the ADT's. After the decoding process is applied on the ADT's and iFDST's, if the byte status has been stored in the ADT's the byte status is updated by the receiver, by the following steps:
- Checking whether a byte which has been labeled before decoding as "with errors" is present in a column whose status has changed from "with errors" before decoding to "error free" after decoding
- Changing the status of such a byte from "with errors" to "error free".
The method further comprises the step of copying the updated byte status and/or the ADST-address stored in the ADT's into the output ADST's.摘要翻译： 本发明涉及一种从发射机向接收机传输数据的方法，特别是在DVB场景中。 由此，数据以连续突发传输，并且每个突发包括多个多协议封装（MPE）和多协议封装 - 突发间突发前向纠错（MPE-iFEC）部分，由此MPE部分携带ADST地址 包含必须写入相应MPE部分内容的应用数据子表（ADST）中的位置。 ADST地址和/或每个字节的状态存储在ADST中，同时映射ADST和iFDST中突发的内容，从而将每个字节的状态标记为“无错误”或“有错误”。 这个ADST地址和/或字节状态被进一步写入ADT中，同时将ADST的内容映射到ADT中，以便ADST地址和/或字节状态从ADST传送到ADT。 在解码过程应用于ADT和iFDST之后，如果字节状态已经存储在ADT中，则接收器更新字节状态，步骤如下： - 检查在解码之前标记为“with 错误“出现在状态从解码前的”有错误“变为解码后的”无错误“的列中 - 将这种字节的状态从”有错误“改变为”无错误“。 该方法还包括将存储在ADT中的更新的字节状态和/或ADST地址复制到输出ADST中的步骤。

摘要： The invention is related to a method of transmitting data from a transmitter to a receiver in particular in a DVB-scenario. Hereby data is transmitted in consecutive bursts and each burst comprises a plurality of Multi-Protocol Encapsulation (MPE) sections and additionally Multi-Protocol Encapsulation - inter-burst-Forward Error Correction (MPE-iFEC) sections and / or Multi-Protocol Encapsulation- Forward Error Correction (MPE-FEC) sections. The content of the transmitted MPE-sections and MPE-iFEC or MPE-FEC sections is mapped into an Application Data Sub-Table (ADST) and an inter-burst-Forward Error Correction Data Sub-Table (iFDST) or Forward Error Correction Data Sub-Table (FDST) respectively. The content of the ADST and iFDST is mapped into ADT's and iFDTS's respectively as far as MPE- and MPE-iFEC sections are concerned. The decoding process is applied on a particular set of ADT and iFDT for MPE- and MPE-iFEC sections and on the ADST and FDST for MPE and MPE-FEC sections and after the decoding was performed on a particular set of ADT and iFDT the data part is copied back into ADST's.
According to the invention the ADT and iFDT or ADST and FDST on which decoding shall be applied is divided into several subblocks before being decoded, each subblock containing one or more lines of the ADT and iFDT or ADST and FDST. Each subblock is then forwarded to the decoder, so that decoding is applied on this subblock, whereby the decoder computes the column status for each subblock, namely the total number of erroneous or missing columns in this subblock and decides whether the content of each subblock can be decoded or not based on the column status of this subblock.摘要翻译： 本发明涉及一种将数据从发射机发送到接收机的方法，特别是在DVB场景中。 因此，数据以连续的突发发送，并且每个脉冲串包括多个多协议封装（MPE）部分以及另外的多协议封装 - 突发前前向纠错（MPE-iFEC）部分和/或多协议封装 - 前向纠错（MPE-FEC）部分。 所发送的MPE部分和MPE-iFEC或MPE-FEC部分的内容被映射到应用数据子表（ADST）和突发间前向纠错数据子表（iFDST）或前向纠错数据 子表（FDST）。 对于MPE和MPE-iFEC部分，ADST和iFDST的内容分别映射到ADT和iFDTS。 解码过程应用于MPE和MPE-iFEC部分的特定的ADT和iFDT集合，以及用于MPE和MPE-FEC部分的ADST和FDST上的解码处理，并且在特定的一组ADT和iFDT上执行解码之后 部分被复制回ADST。 根据本发明，应在其上应用解码的ADT和iFDT或者ADST和FDST在被解码之前被划分成几个子块，每个子块包含ADT和iFDT或ADST和FDST的一行或多行。 然后将每个子块转发到解码器，使得解码被应用于该子块，由此解码器计算每个子块的列状态，即该子块中的错误或缺失列的总数，并且确定每个子块的内容是否可以 根据该子块的列状态进行解码。

摘要： The invention is related to a method of transmitting data from a transmitter to a receiver, in particular in a DVB-Scenario. Data is transmitted in consecutive bursts and each burst comprises a plurality of MultiProtocol-Encapsulation (MPE) and Multiprotocol-Encapsulation-Inter-Burst Forward Error Correction (MPE-iFEC) sections. The data part of a burst (K) is not necessarily completely filled and thus contains a padding , i.e. it is possible that there is no data at the end of the ADST.
The transmitted sections comprise a time-slicing indicator indicating the remaining time (Δt) until the start of the next burst. Each time a section is detected the next burst start is calculated. For each MPE-section the receiver compares the time at which the next burst should start and the current time in order to decide whether this MPE-section belongs to the same burst or to a new burst.
According to the invention each time a section is detected the receiver calculates the time at which the next burst should start by adding to the current time the remaining time (Δt) indicated by the time-slicing indicator present in the detected MPE-section and subtracting therefrom an offset-value which is chosen depending on a processing time delay at the receiver.
An independent invention is related to a new method for detecting the presence of a new burst.摘要翻译： 本发明涉及一种从发射机向接收机发送数据的方法，特别是在DVB场景中。 数据以连续的突发发送，并且每个突发包括多个多协议封装（MPE）和多协议封装 - 突发间前向纠错（MPE-iFEC）部分。 突发（K）的数据部分不一定完全填充，因此包含填充，即可能在ADST结束时没有数据。 发送的部分包括指示直到下一个突发的开始的剩余时间（“t”）的时间分割指示符。 每次检测到一个部分时，计算下一个突发启动。 对于每个MPE部分，接收机比较下一个突发应该开始的时间和当前时间，以便决定该MPE部分是否属于同一个突发或新的突发。 根据本发明，每次检测到一个部分时，接收机通过将检测到的MPE部分中存在的时间限制指示符指示的剩余时间（“t”）加上当前时间，计算下一个突发应该开始的时间， 从其中减去根据接收机处理时间延迟而选择的偏移值。 独立的发明涉及用于检测新突发的存在的新方法。

The burst size of a burst (K) is indicated by the previous burst size field present in the header of each MPE-iFEC section in different other bursts or in the same burst (K).
According to the invention, the burst K is only processed after its size is known by using the information present in different other bursts (K+1, K+2,...) or in the same burst (K).
