Delivery and monitoring system for outdoor electronic information broadcast network

Abstract

The invention discloses a delivery and monitoring system for an outdoor electronic information broadcast network, which is characterized in that a delivery broadcasting unit delivers safely video programs and program menus to a plurality of program broadcasting modules through a network; the program broadcasting modules broadcast programs in accordance with arrangement of the program menus; a monitoring return unit monitors parameters of site environment and live broadcasts, avoids faults of front end systems and equipment, and even prevents criminals from directly illegally broadcasting uncensored and unapproved content at the front end; and a signal acquiring unit can achieve the acquirement of site environmental parameters and monitoring audio and video signals in unattended situations. The system can be operated continuously, is suitable for day time, night time and various severe environments, achieves that video and audio files are delivered to a front end broadcasting node for broadcasting through the network, and monitors all broadcasting points in real time. The data transmission of the system is safe and reliable, monitoring pre-warning, processing and response are timely, extension capability of front ends is strong, and the system is suitable for centralized monitoring of the outdoor electronic information broadcast network and large-scale disposition of front end nodes.

Description

technical field [0001] The invention relates to a distributed safe delivery and monitoring system for video programs, more specifically a safe delivery and real-time monitoring system for distributed terminals with large outdoor LED screens. Background technique [0002] With the advancement of science and technology and the take-off of the economy in recent years, the development and application of outdoor LED large screens is very rapid. LED large screens are usually located in crowded downtown areas, with a large audience and wide influence. There have also been incidents of LED large screens playing bad content around the world, and the processing speed of the incident is slow, causing bad social impact. In order to ensure the safety of broadcasting, most of the existing outdoor LED large-screen broadcasting still choose the traditional single-point broadcasting method, which makes the program update slow, time-consuming and laborious. At present, some multi-terminal si...

LED large screens are usually located in downtown areas with a large number of people, with a large audience and wide influence. There have also been incidents of LED large screens playing bad content around the world, and the processing speed of the incident is slow, causing bad social impact.

In order to ensure the safety of broadcasting, most of the existing outdoor LED large-screen broadcasting still choose the traditional single-point broadcasting method, which makes the program update slow, time-consuming and laborious

At present, some multi-terminal simulcast systems have emerged, but the coverage is small, and it is difficult to meet the cross-regional promotion of news, live broadcast and advertisement content. In addition, in order to ensure the safety of the large screens of each terminal, it is usually necessary The playback nodes are assigned special personnel on duty, which also brings a lot of manpower and material resources to the operation and maintenance of the system
