Station-wide UMD, Station-wide Monitoring and Station-wide Matrix Scheduling System of Mianyang TV S
 

Station-wide Monitoring and Matrix Switching System for the New Building of Sichuan Mianyang TV Station

I. System Overview

The audio and video process system for the new building of Mianyang TV Station consists of station-wide broadcast master control system, studio group sub-control system, studio system and other systems.

II. Overall Architecture

According to the audio and video systems division and characteristics of the corresponding business system space deployment of Mianyang TV Station, the station-wide monitoring system is composed of four parts, namely master control system equipment monitoring and signal alarm, broadcast system equipment monitoring and signal alarm, studio group equipment monitoring and signal alarm and master control matrix control system.

The entire system is equipped with a monitoring server to achieve system-wide equipment monitoring and signal alarm functions.

III. Realization of Functions

Functions of each monitoring system throughout the station are required as follows: 1. studio group part: studio group equipment monitoring and signal alarm; 2. broadcast system equipment monitoring and signal alarm; 3. master control system equipment monitoring and signal alarm.

IV. Technical Characteristics of the System

Technical characteristics of the station-wide monitoring system include two aspects: one is networking technology, which allows the internal monitoring system of various audio and video systems to run independently, and also depend on the network to access controlled equipment and technical supervision equipment; the other is all the software functions and indicators of the internal monitoring system of each system can meet the requirements of the station.

Station-wide Source Name Tracking System for the New Building of Sichuan Mianyang TV Station

I. Demand Profile

The audio and video process system for the new building of Mianyang TV Station is composed of station-wide broadcast master control system and studio system. The broadcast master control system features station-wide unified signal scheduling and program broadcasting, while the studio sub-control system features signal scheduling from the master control to each studio and among different studios

Each audio and video system is equipped with well-developed signal routing switching equipment and signal monitoring equipment, which can fulfill their respective technology functions, and each system can achieve flexible signal scheduling in between through routing matrix to meet the recording and broadcasting requirements of different types of programs.
In order to achieve signal scheduling between systems and dynamically display the source name function of scheduled signals, the design of a station-wide UMD (Under Monitor Display) source name tracking system is required.

II. Overall Architecture

According to the audio and video systems division and characteristics of the corresponding business system space deployment of Mianyang TV Station, the station-wide UMD source name tracking system is composed of broadcast master control system UMD system, studio group sub-control UMD system and studio group UMD system. Each system is internally equipped with separate UMD TALLY control host, dynamic source name driver, source indicator and other equipment to achieve independent UMD source name tracking function. Meanwhile, the systems are interlinked via the Ethernet, and a redundant chain is designed in the connection chain to ensure the reliability and safety of source name information exchanges.

III. Introduction to System Functions
The functional requirements of each UMD system throughout the station are as follows:
System name UMD

Number of UMD hosts

 Description of functions
1. Broadcast master control part
Broadcast master control system

1 set of UMD control host

1. Define external signals’ source name
2. Multi-screen split screen signals’ source name information and switch instructions
3. Network with other systems to achieve source name exchange
Broadcast sub-control system1 set of UMD control host 1. Receive the master control system’s source name information, and forward the master control system’s source name to studio groups
2. Define external signals’ source name
3. Multi-screen split screen signals’ source name information display and switch instructions
4. Network with other systems to achieve source name exchange


2. Studio part


80-sqm studio

1 set of UMD control host

1. Receive master control system’s source name information
2. Define external signals’ source name
3. Multi-screen split screen signals’ source name information display and switch instructions
4. Trigger CCU and monitor static TALLY pilot lamps
5. Network with other systems to achieve source name exchange
120-sqm studio

1 set of UMD control host

1. Receive master control system’s source name information
2. Define external signals’ source name
3. Multi-screen split screen signals’ source name information display and switch instructions
4. Trigger CCU and monitor static TALLY pilot lamps
5. Network with other systems to achieve source name exchange
250-sqm studio 1 set of UMD control host 1. Receive master control system’s source name information
2. Define external signals’ source name
3. Multi-screen split screen signals’ source name information display and switch instructions
4. Trigger CCU and monitor static TALLY pilot lamps
5. Network with other systems to achieve source name exchange
IV. Technical Characteristics of the System
Technical requirements of the station-wide UMD TALLY source name tracking system include two aspects. One is networking technology. Under the premise of operating independently, the UMD system within each audio and video system can also depend on the network to achieve dynamic exchange of source name information so as to realize cross-system traceability of source name display. The other technology is that all TALLY signal sources involved in the internal UMD system within each system, including routing equipment such as studio switcher, matrix routing equipment, source name pointing device such as multi-screen slicer, dynamic source name display TALLY lamp, static TALLY lamp, monitor’s auxiliary TALLY lamp, CCU TALLY pilot lamp and other equipment, can correctly drive the corresponding TALLY pointing devices’ source name information and TALLY lamp display state according to the state of the switching equipment combined with the TALLY logic.
