Definitions

  • the present invention relates to a device for the safe playback of audio and video data in a computer network, in particular in the Internet.
  • a computer network in particular in the Internet.
  • simplified generation and display of data in a computer network is made possible.
  • Such play systems are known in the prior art. With the well-known play systems, the contributions from one Archive transferred to a PC card and, if necessary, decoded, mixed and leveled. The PC controls these processes. The resulting data stream is then transferred to a second PC, which is used for encoding and feeding into the network (e.g. Internet).
  • the network e.g. Internet
  • This method is used particularly successfully by radio stations and program or music producers.
  • the PC hardware is not designed for uninterrupted signal processing, but is basically based on the property of interrupting processing for unavoidable hardware waiting times. These interruptions are also exemplified by one above Real-time operating system only bypassed to a certain extent, but cannot be completely excluded from the network due to unpredictable events. It is precisely these unpredictable random events that are excluded in the dedicated hardware according to the present invention, since the hardware and the software only have to fulfill this task of processing the data streams and are only designed specifically for this purpose.
  • a disadvantage of the known systems is that at least two PCs are required for each channel or transmitter, one PC being responsible for the procurement, decoding, mixing and leveling of the contributions provided from an archive and the second PC for encoding and Generation of a so-called streaming source that feeds the actual connection to the network into the network according to a pre-agreed protocol.
  • the object of the invention is to provide a new system which is able to transmit data streams of a certain number of channels over a to supply and remove special hardware from a network, ensuring increased operational reliability and at the same time reducing the costs of the system.
  • the data output system for connection to a network with at least one commercial personal computer which has a control plug-in card for controlling the data streams from at least one archive and / or at least one network, e.g. Internet, records, is a plug-in card carrier that receives a plurality (s) of plug-in cards, each of which is assigned to a data transmission channel and electronically processes the data streams of the different channels.
  • plug-in cards instead of one or more PCs, which would be conceivable in the proposed new system according to the invention, a plurality of plug-in cards will be used in a plug-in card carrier.
  • These plug-in cards carry electronics known per se, which processes the specified data streams in accordance with a specified program and then releases them for data transmission into the network.
  • electronics known per se are used on the plug-in card in the plug-in card carrier, and their data stream processing is also used a commercial PC could of course take over.
  • the process or system consists of various components, e.g. are contained in the data output system according to the invention as a circuit or executable program for a digital signal processor (DSP).
  • DSP digital signal processor
  • the implementation of plug-in cards in a card carrier is of particular advantage for the data playout system.
  • the individual processes are carried out here using special programs in a circuit on the plug-in card.
  • the timing of the execution of the processes on the computer is not deterministic.
  • the processes on the computer are held up by unpredictable and unpredictable interruptions.
  • This disadvantage is avoided with a dedicated circuit according to the invention, so that an uninterrupted, predictable processing of the adjacent real-time processes is ensured without being affected by unpredictable other processes.
  • the stability of the processes is significantly increased.
  • the hardware of the system can be expanded up to a number of (n) plug-in cards in the card carrier, where (n) represents any reasonable number.
  • (n) represents any reasonable number.
  • additional, independent content can be displayed in a framework program of the data play-out system according to the invention with the aid of the circuit.
  • Time slots are provided for this within the framework program, into which further contributions can be faded in using a suitable control protocol, e.g. Advertising posts.
  • This process can also be carried out in several stages, i.e. Additional content is displayed in a supporting program, so that a new structure of the supporting program is created.
  • a program can be adapted to local requirements.
  • a framework program that is intended for all of Germany can be modified to specific framework content for a framework program for Bavaria.
  • Another major advantage is that real-time data exchange between the interface card in the PC and the card carrier is carried out via a broadband communication interface.
  • the card carrier and thus the plug-in cards in the card carrier are controlled via a real-time protocol or an automation list that was previously transmitted.
  • This real-time protocol is carried out over the network with low bandwidth. Monitoring is also possible through the network.
  • the control and monitoring of the plug-in cards in the card carrier can be carried out using the PC via the same communication interface that is used for real-time data exchange.
  • Another advantage in the system according to the invention can be seen in the fact that the signal processing is distributed in the network, as a result of which the program generation for a transmitter can be positioned as close as desired to the receiver. As a result, the relatively large bandwidth for transmitting the program is only required for a short distance.
  • An advantage of the system according to the invention is the possibility to process the so-called live streams from the network (e.g. Internet) in addition to the archive contributions.
