Problems solved by technology

[0003] At the same time, in traditional TV stations, the commonly used signal routing devices are switchers and master control devices. These devices will switch and route signals between multiple input and output devices in a matrix manner, but these devices Generally, it only supports SDI or CVBS signal input and output. With the rapid development of new media today, it is useless for routing switching of new media signals.

Embodiment 1

[0051] Embodiment 1. A signal switching matrix system, such as figure 1 shown, including:

[0052] Multiple signal acquisition servers, multiple signal distribution servers and switches;

[0053] a management server, configured to instruct the signal collection server to forward signals to a designated signal distribution server;

[0054]Each of the signal acquisition servers is respectively used to receive an input signal, and decapsulates to obtain a video and audio coded data stream; forwards the video and audio coded data stream to a signal distribution server designated by the management server through the switch;

[0055] Each of the signal distribution servers is respectively used to receive the video and audio coded data stream forwarded by the signal collection server, perform video and audio recoding and repackaging, and then output.

[0056] In this embodiment, in addition to performing forwarding control on the signal collection server, the management server can ...

Abstract

The invention discloses a signal switching matrix system, which comprises multiple signal collecting servers, multiple signal distributing servers, an exchange board and a management server, wherein the management server is used for indicating the signal collecting servers to transmit signal to the signal distributing servers, the signal collecting servers are respectively used for receiving the input signal and decapsulating to obtain video / voice frequency coded data stream, the video / voice frequency coded data stream can be transmitted to the signal distributing servers through the exchangeboard, the signal distributing servers are respectively used for receiving the video / voice frequency coded data stream transmitted by the signal collecting servers to carry out the recoding for the video / voice frequency and the output after being capsulated again. According to the invention, the matrix switching for multiple signals can be carried out.

Description

technical field [0001] The invention relates to the field of multimedia, in particular to a signal switching matrix system. Background technique [0002] With the rapid development of multimedia technology and IT technology, the multimedia signal formats and protocols involved in traditional media and new media fields are constantly increasing. As typical representatives, SDI signals in the traditional radio and television industry, various streaming media signals in the new media field, and files in various formats occupy different proportions in each field. Since the formats and protocols of these signals are different, the signals that can be received and output by equipment used in various fields and links also have limitations. Therefore, there are various signal conversions in the industry, such as the mutual conversion from SDI to streaming media. Conversion equipment, conversion software between streaming media, etc. [0003] At the same time, in traditional TV sta...
