Abstract
The utility model discloses a recording and broadcasting central control machine, comprising video input interfaces, video output interfaces, audio input interfaces, audio output interfaces, a serial interface, an infrared interface, a power supply output interface, network interfaces and a relay interface. The recording and broadcasting central control machine is characterized in that: all the interfaces are managed and controlled by using an embedded operating system; and the number of the video input interfaces, the video output interfaces, the audio input interfaces and the audio output interfaces are a few, the video input interfaces and the video output interfaces are VGA interfaces or BNC interfaces, and the VGA interfaces identify the resolution of output external equipment and automatically adjust the resolution of input equipment. The recording and broadcasting central control machine has strong applicability, is simple and convenient, can control and connect various external equipment, and can better complete the recording and broadcasting.
Description
Technical field
The utility model relates to middle control machine, refers to that especially a kind of VGA interface can adapt to control machine in the recorded broadcast of resolution automatically.
Background technology
Along with improving constantly of the fast development of modern network science and technology and video, audio encoding and decoding technique, make and popularize rapidly based on the long-range audio frequency and video interactive device of the Internet, and widely apply at aspects such as teleconference, remote teaching.In long-distance education, generally adopt recording and broadcasting system that teacher's content of teaching is carried out live recorded broadcast.What recording and broadcasting system started to control making usefulness is middle control machine, is responsible for the switching of input and output and coordinates.In the prior art, the general mode of inserting the expansion interface plate that adopts of the middle control machine of recording and broadcasting system increases the interface value volume and range of product, maintenance cost height, inconvenience during switching.Secondly, the resolution that middle control machine connects input and output device has difference, when the resolution of input equipment during greater than the resolution of output equipment, can cause the paralysis of system.Moreover middle control machine is limited to its system and structure, can't satisfy the diversified demand of resolution.The problems referred to above are needed solution badly.
Summary of the invention
The utility model technical issues that need to address provide a kind of operation of being convenient to, and are suitable for plurality of devices, can coordinate to import and the recorded broadcast of output equipment resolution in the control machine.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
Control machine in a kind of recorded broadcast, comprise video input interface, video output interface, audio input interface, audio output interface, serial line interface, infrared interface, power output interface, network interface and relay interface, it is characterized in that: manage and control described total interface with embedded OS.Embedded OS EOS (Embedded OperatingSystem) is a kind of broad-spectrum system, is responsible for whole soft, the distribution of hardware resource, the traffic control of embedded system, and concurrent activity is coordinated in control; It must embody the feature of its place system, can reach the desired function of system by the loading and unloading certain module.
Further, described video input interface, video output interface, audio input interface, audio output interface have several, video input interface and video output interface are VGA interface or bnc interface, the resolution of VGA interface identification output external equipment, the resolution of regulating input equipment automatically.The VGA interface is the conduction interfaces of common input and output analog signal, be called the D-Sub interface again, and bnc interface is coaxial cablet joint.Can completely cut off video input signals, make signal disturb minimizing each other.
Further, the ultimate resolution of described VGA interface support is 2048 * 1536 pixels.
Further, described network interface comprises gigabit network interface and 100-M network Ethernet.
Compared with prior art, the utility model has following advantage:
One, the utility model can be supported the recorded broadcast transmission between the plurality of devices, and conversion is flexible, and maintenance cost is low.
When two, the utility model used the VGA interface, the resolution between energy automatic synchronization input equipment and the output equipment was safeguarded the normal operation of recording and broadcasting system.
Three, the VGA interface can be suitable for multiple resolution, and the control machine can both receive and handle output in the external equipment access recorded broadcast of different resolution.
Description of drawings
Fig. 1 is the structure chart of the utility model embodiment.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
In conjunction with Fig. 1, the utility model has related to control machine in a kind of recorded broadcast, comprise video input interface, video output interface, audio input interface, audio output interface, serial line interface, infrared interface, power output interface, network interface and relay interface, described total interface adopts embedded OS to manage and control; Described video input interface, video output interface, audio input interface, audio output interface have a plurality of, video input interface, video output interface are the VGA interface, the resolution of VGA interface identification output external equipment, the resolution of regulating input equipment automatically.The ultimate resolution of VGA interface support is 2048 * 1536 pixels.Network interface comprises gigabit network interface and 100-M network Ethernet.The output parameter of relay interface comprises and exchanges two kinds of 5A/250V and direct current 5A/30V, controls energising and the outage of a plurality of external equipments; And the parameter of power output interface is two kinds of direct current 5A and direct current 12A, can give a plurality of external equipments power supplies.The utility model applicability is strong, and is simple and convenient, and the multiple external equipment of energy control connection is better finished recorded broadcast.
