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： Modern computers (10, 20) come with different timers having different attributes like time resolution, supported time range and time reference. Some are local timers, representing relative time values like the TSC counter (11, 21) counting CPU cycles from the power on or reset of the computer. Some are global timers, representing an absolute or real time. Having different classes of timers in the computer (10, 20), a number of computations need to be performed to tie the different timers to each other.
It is the idea of the invention to define a single high resolution timer structure wherein the time value is represented with a digital number and a flag clarifies whether the timer is a global timer or local timer. The invention enables a much faster processing of the time values. The global time, tied to a high-resolution timer can be tracked much faster. This means better precision of scheduling of time critical jobs, like packet scheduling for data transport.
摘要翻译：现代计算机（10,20）具有不同的定时器，具有不同的属性，如时间分辨率，支持的时间范围和时间参考。有些是本地定时器，表示相对时间值，如TSC计数器（11,21）计算计算机开机或重置计算机的CPU周期。一些是全球定时器，代表绝对或实时。在计算机中有不同类别的计时器（10,20），需要执行许多计算来将不同的计时器彼此联系起来。本发明的构思是定义一个单一的高分辨率定时器结构，其中时间值用数字数字表示，并且标志阐明定时器是全局定时器还是本地定时器。本发明能够更快地处理时间值。与高分辨率计时器相关的全球时间可以更快地跟踪。这意味着时间关键型作业的调度精度更高，例如数据传输的数据包调度。

摘要： The invention relates to a new type of quality of service architecture for a network assembly and a corresponding computer network system. The Internet technology as approved by the IETF organization has defined different services. One is the integrated services (IntServ) and the other the differentiated services (DiffServ) architecture. Another is the RSVP Protocol according to which Quality of Service can be implemented with accuracy and richer functionality.
The invention shows a way how less sophisticated QoS managers inside the network with only DiffServ or Intserv capability, can be used for enhancing the QoS functionality based on so-called RSVP shadowing messages, and easy to implement RSVP shadowing stacks.
