TV Speech In Image Times

In TV transmission, the sender and the receiver of message are respectively at the two poles of the transmission. The transmitted message must be encoded through certain kinds of media. To encode is to organize the sign-arrays come from the source into the best series through given consequences. From the angle of message transmission, encoding is expression. Expression is as well the process and product of fabricating symbols to represent its meaning, as the process of the socialization of meaning-formation under every efficient signification system. Therefore, TV expression involves signs, the meaning of signs, and the signification system. To be specific, TV expression includes the ways, the contents, the genres, the logic, and the contexts of expressing, et cetera.The way TV expresses itself simply means to treat TV text as a symbol system, a narrative text and a text system with rhetorical color. To convey what kind of information is to study the content-expression and the image-expression of TV. There are many TV genres, each varies in structures, narratives, focuses and some other aspects. The genre-expression deals with the characteristics and the meaning they convey. TV is a form of culture with economic and ideological features. On one hand, TV expresses the substance of culture, economy and ideology; on the other hand, the above-mentioned factors will not only influence TV expression, but will even turn out to be the internal logic of TV expression. The research of context involves textual context, situational context , cultural context and so forth. The process of expression is the very process of textual context-construction, which can also be called contextualization. This kind of constructed context affects contextual expression. Cultural context alludes to the status of existing culture, which is vital to the construction of expression. The cross-culture transmission is a necessity in the frame of global transmission. TV expression should adapt itself to different cultural contexts on which it should be based, and establish a platform of global communication and dyad system. With the development of media technology, the form of media updates constantly, which posts new challenges to TV expression in many aspects, for instance, how message-senders access to various kinds of media to enhance the transmission and expression of TV; message-senders should have the capacity of obtaining and analyzing when they are exposed to all kinds of new or obsolete information.Based logically on the point of expression, this dissertation intends to explore the essence-and-expression disciplines of TV expression theoretically, with an aim to deepen the connotations, to broaden the boundaries, and to multiply the approaches of the study of TV transmission. To a certain extent, the leitmotiv of this dissertation serves as a theoretical washback on TV media research biased either on message-receivers or on their acceptation.
