System of conference of video of network of satellite of Ministry of Agriculture, it is direct of Ministry of Agriculture attempers one of fundamental application of satellite communications system, be debugged through second conference, system is being figured two years between a long time and integrated drilling, the system moves to already was stabilized gradually, can assume the video conference of diversiform type. Should see, this system is to be below the attention of leader of Ministry of Agriculture and support, in the Ministry of Agriculture departmental door and the support that save door of Ministry of Agriculture each fall, ability is able to build quickly and application rises. From current application the circumstance looks, still existing the issue that a few earnestly want to solve.
1, conference organization job and relevant system are not quite perfect. Technology of countrywide video conference supports a system to had been not built truly, the liability that various video conference uses is uncertain still, about the conference organization and support still do not have specific provision and system, duty has not fulfilled a person.
2, the construction of partial branch field still is not perfected. Provincial branch field did not provide the part video conference terminal, video assembly room also was not secured, terminal of conference of the video when attending a meeting should move back and forth, move circuit and installation temporarily; The set that visits office partly is sowed receive equipment to be not secured, install temporarily when receive, influence conference watchs the effect.
3, the satellitic bandwidth that video conference transmits is insufficient. The satellitic bandwidth that buys formerly can make sure a province undertakes only online time pass, call of bandwidth parameter, MCU should be revised to wait to need proper time when switch.
4, the support of video conference technology that did not build a full-time serves a team. Ministry, province need of technology of staff member operation raises two level further, to conference equipment the operation returns insufficient adroitness, still cannot handy.
5, field of provincial video branch is less. The branch field that at present each province can watch ministry video conference is only, cannot satisfy the need that holds meeting of whole system video far.
Next, we plan to do good key work: 1, clutch perfect management system, the organization that strengthens the conference works. 2, the operating rules of personnel of farther perfect technology. 3, the construction that accelerates branch field. 4, accelerate direct of Ministry of Agriculture to attemper whole nation of satellite communications system works with the construction of project of city couplet net. 5, the problem that solves inadequacy of good satellite bandwidth as soon as possible.
