That is to say,the IPTV architecture should carry a myriad of services and technologies. In light of current telecom/TV status,the IPTV architecture can be set up on the convergence of the three networks to deliver comprehensive services and make Live TV,TV on Demand (TVOD),and Time-shifted TV services accessible on one platform. It also supports local and cross-regional user and service certification,provides EPG and smooth TV images and guarantees secured content as well.展开更多

For a long time, China’s modern services have been backward and played an insignificant role in the national economy. Sluggish growth of modern services is particularly dragging on China’s otherwise surging economic and social development; and it puts a strain on industrial restructuring and efforts to build a prosperous and harmonious socialist society. This paper sheds light on outstanding issues concerning the role of China’s modern services in various arenas, including transforming the economic growth pattern, improving economic structuring, upgrading the industrial structure, facilitating technological progress and spurring changes in the employment structure. Based on in-depth analysis, this essay proposes policies and countermeasures for the promotion of modern services.展开更多

Aiming to promote better standards of living to the Latin American rural population, AIA is merged in a historical context of increasing US economic and politic influence over Latin America and Brazil, diffusing and adapting US technical assistance programs to local contexts. However, this research developed the idea of an intense process of political negotiation, including resistance from Brazilian political staff. Also, there were many difficulties in adapting these programs to the local context, leading to constant reorganization of the AIA＇s work in Brazil.展开更多
