The Research On Scheduling And Schedule Control Of LN Broadcasting And TV Station Terrestrial Channels's SD&HD Simulcasting Project

High definition television is the third generation of television after black and white TV and color TV.It was the trend of TV development in the future.It is one of the core competitive products in a TV station,which makes full use of the content and dissemination advantages to cope with new media such as mobile phones and tablet computer.Currently,SD&HD simulcasting of radio and television industry in our country is in the transitional stage of transition to an information technology age.With the gradual increasing of construction project in recent years,project management is gradually changing from extensive type to intensive type.Taking present scarcity of HD channel resources into consideration,as well as the audiences' viewing habits that once they watch more HD television programs,they would not like to watch SD TV programs any more.For LN broadcasting and TV Station,who wish to realize"overtaking at the turn",achieving SD&HD simulcasting in the station as soon as possible is not only a show of corporate image and strength,but also an important opportunity to improve the overall management level of the station.The theoretical research of schedule management in our country is comparatively mature,which was applied widely in construction and industrial fields.So far,in the field of radio and television,however,very few articles have been published in the field of project schedule management of television engineering.And no articles analyses intensively the project construction schedule and control of radio,film and television using the theory of plan and control of schedule has been published yet.This article makes a deep analysis on the specific application of project control plan and control methods in the project of SD&HD simulcasting terrestrial channels.This can provide reference solutions for project management of similar projects of radio and television industry,and this study is also of some reference value to project management of this industry.Based on the development of radio and television in China,this study aims at the construction target of the SD&HD simulcasting project construction of LN broadcasting and TV Station.It uses the related theory of WBS?CPM?PERT as well as Gantt chart and the principle of network planning of plan and control of schedule project management to makes work breakdown structure and activity duration estimation.Besides,it also prepares reasonable schedule.At the same time,this study analyses risk factors which may impact the project construction as well as process monitoring and control system and system adjust process in control of project schedule.Finally,it put forward corresponding schedule control methods.
