限定性是形成电视节目形态的重要前提,没有限定性就没有电视节目的形态特征。从电视节目发展的实际情况来看,形态的限定性正在逐渐增强,这是电视节目工业化生产的需要,是媒体在激烈竞争时代的选择。电视节目形态的限定是通过题材的限定、内容的具体化、人物的限定,结构的组织安排、主持人的功能化等手段具体实现的。限定性不会带来形态的僵化,恰恰有利于电视节目总体的生态繁荣。 Qualification is an important precondition for the formation of a television program. There is no limit to the morphological characteristics of a television program. Judging from the actual situation of the development of television programs, the definition of the form is gradually increasing. This is the need of the industrialized production of television programs and the choice of the media in an age of intense competition. The definition of television programs is achieved through the limitation of the theme, the concrete content, the limitation of characters, the organization of the structure and the functionalization of the host. Limitation will not bring the rigidity of the form, it is precisely conducive to the overall ecological prosperity of television programs.
