摘要： The invention relates to a method for packet-switching transmission of media data and a device for processing media data. Media data may be video, audio or text data, or other data. Transmission of the data is usually effected according to a streaming method. The data is therein transmitted in packets and re-assembled in the receiving device. For Internet applications, the real-time transport protocol is very widely used in the transmission of data streams. However, this data transmission protocol does not enable a secure transmission which is based on a repetition of the defectively transmitted data. Sequence counters are used according to this protocol so that left- out data packets can be detected in the receiving device. According to the invention, it is provided that error information data is inserted in the destination media data record which is generated from the received data in the receiving device when, according to the transmission protocol, transmission errors are detected in the analysis of the data packets received. The transmission errors are then documented in the destination data record. The stored error information can be analyzed upon reproduction of the destination data record so that it can be evaluated, in particular, whether the recorded original data is so seriously defective that a new recording is inevitable. In particular, this is advantageous in video production where it is necessary to quickly evaluate whether a recorded film or video scene is of acceptable quality (if necessary, taking potential retouching into account) or whether it must be repeated and recorded again.
摘要翻译：本发明涉及一种用于分组交换媒体数据传输的方法和用于处理媒体数据的设备。媒体数据可以是视频，音频或文本数据或其他数据。数据的传输通常根据流传输方式进行。数据在其中以分组方式传输并重新组装在接收设备中。对于互联网应用，实时传输协议在数据流的传输中被广泛使用。然而，该数据传输协议不能基于重复的缺陷传输数据实现安全传输。根据该协议使用顺序计数器，以便在接收设备中可以检测到不存在的数据包。根据本发明，在根据传输协议在数据分组的分析中检测到传输错误时，将错误信息数据插入到从接收设备中的接收数据生成的目的地媒体数据记录中接收。然后将传输错误记录在目标数据记录中。可以在再现目的地数据记录时分析所存储的错误信息，使得可以特别地评估所记录的原始数据是否严重缺陷，使得新的记录是不可避免的。特别地，这在视频制作中是有利的，其中有必要快速评估录制的电影或视频场景是否具有可接受的质量（如果需要，考虑到潜在的修饰），或者是否必须重复记录。

摘要： A method for converting video data comprises providing video data in a first format, selecting consecutive pixel data corresponding to a line or fraction of a line of an image, and adapting a maximum length of a data packet to accommodate the selected pixel data. The payload section of a data packet exclusively carries pixel data originating from one single line of the source image. The method further comprises calculating a start address for a memory in a receiver beginning at which address the pixel data is to be written. The start address is added to a header section of the data packet in the transmitter. The data packet is transmitted via a network. In the receiver the pixel data is written to the memory beginning at the start address indicated in the header section. Video data is read from the target memory in accordance with a second format.

摘要： The present invention relates to a method of managing a packet administration map for data packets to be received via a network, particularly for packet groups organized in sequences of consecutive packets. In the field of networking and reliable data transport, as for example in case of TCP, bursty packet drops occur during a data transmission. Especially in high speed networks like in 10 Gb Ethernet, the handling of lost and retransmitted packets can introduce a disproportionate decrease of the net data rate. A reliable transport protocol usually retransmits a data packet that a receiver was not able to receive and thus was not acknowledged. In order to manage data packets that are retransmitted, a receiver in the network monitors sequence numbers and stores missing sequence numbers within an internal data structure, called packet administration map. According to the invention a reversed keying is used which means that the upper limit of the range of contiguous missing data packets is used as the key entry in the administration map. As the retransmitted packets usually are retransmitted in an increasing order of sequence numbers, with the help of the invention it becomes very seldomly necessary to split a packet administration entry or to create a new packet administration entry.
摘要翻译：本发明涉及一种管理要经由网络接收的数据分组的分组管理映射的方法，特别是针对以连续分组的顺序组织的分组组。在网络和可靠数据传输领域，例如在TCP的情况下，在数据传输期间发生突发分组丢失。特别是在像10 Gb以太网这样的高速网络中，丢失和重发数据包的处理可能会导致净数据速率的不成比例的下降。可靠的传输协议通常重传接收机不能接收的数据分组，因此未被承认。为了管理重传的数据包，网络中的接收器监视序列号，并在内部数据结构中存储丢失的序列号，称为数据包管理映射。根据本发明，使用反向键控，这意味着连续丢失数据分组的范围的上限被用作管理图中的键入口。由于重传的分组通常按照序列号的增加顺序被重传，借助于本发明，分割分组管理条目或者创建新的分组管理条目变得非常必要。

摘要： In video production sites, video material is stored on video servers in digital form. High speed networks are available for transferring video content from the video servers to workstations for post-processing like video editing, colour management etc. Most networks and a lot of software for post-processing are available for exchanging data with Internet protocol. Extensions for the RTP protocol are available for transporting high definition video/audio data based on an Internet Protocol stack. The invention enables the overall control of the data streaming by setting two incompatible flags (405, 406) in one and the same RTP packet without the need of a further extension of the RTP protocol. In one example the end of a data stream is signalled by setting the frame begin plus frame end flag (405, 406) in the packet transporting the last part of the last DPX frame in the stream.
摘要翻译：在视频制作网站中，视频资料以数字形式存储在视频服务器上。高速网络可用于将视频内容从视频服务器传输到后处理工作站，如视频编辑，色彩管理等。大多数网络和大量用于后处理的软件可用于与互联网协议交换数据。 RTP协议的扩展可用于传输基于互联网协议栈的高清视频/音频数据。本发明通过在一个和相同的RTP分组中设置两个不兼容的标志（405,406）而不需要RTP协议的进一步扩展来实现对数据流的总体控制。在一个示例中，通过在传输流中最后一个DPX帧的最后部分的分组中设置帧开始加帧结束标志（405,406）来发信号通知数据流的结尾。
