Description

Technical Field

[0001] The utility model relates to the technical field of switchers, in particular to a multi-format video switcher for IP / SDI transmission. Background Art

[0002] IP / SDI transmission involves the transmission method of video signals. In the video field, IP (Internet Protocol) and SDI (Serial Digital Interface) are two common video signal transmission standards. IP transmission: IP transmission refers to the use of network protocols (such as TCP / IP) to transmit video signals. By converting video signals into digital data packets and transmitting them over the network, remote video transmission and distribution can be achieved. IP transmission can be carried out over a local area network, a wide area network, or even the Internet, providing flexibility and scalability for a variety of application scenarios. SDI transmission: SDI transmission refers to the transmission of video signals using the SerialDigital Interface standard. SDI is a digital video interface standard that is commonly used for connections between professional video equipment, such as cameras, video monitors, video routers, etc. SDI transmission provides high-quality video transmission and supports high-definition video and audio signal transmission.

[0003] In practical applications, IP and SDI transmission each have their own advantages and applicable scenarios: IP transmission is suitable for scenarios that require remote video transmission, network video distribution, video surveillance, etc., and can achieve flexible video stream management and remote access. SDI transmission is suitable for scenarios that require high-quality video transmission, professional video production and broadcasting, and provides stable, high-definition video signal transmission. In some scenarios, IP and SDI transmission are also used in combination, such as converting SDI signals into IP data streams for network transmission, or converting IP data streams into SDI signals for output to professional equipment.
