Background technology
As everyone knows, television program designing company is except obtaining the part of my profit quite most income, the main paid period advertisement charging that still derives from the numerous enterprises product by issuing the TV programme itself of oneself making.With regard to the distribution of TV programme, generally do not exist issuing the selection in area, and the propaganda of the product advertising of enterprise to be quite different, they can selectively carry out at different regions.For this reason, when television program designing company issues same TV programme in different regions, can insert corresponding different products propaganda advertisement, thereby produce many versions phenomenon of TV programme according to the specific requirement of different enterprises.
Traditional multi-edition TV program structure comprises: main body program+ad content.Its specific constructive form can be referring to Fig. 1:
(1) when inserting one section advertisement, there is " film leader section, advertisement * * .1 and reel end section " structure in example, and does not have medium film section.
(2) when inserting two sections advertisements, just exist " film leader section, advertisement * * .1, medium film section 1, advertisement section * * .2 and reel end section " structure;
(3) when inserting three sections advertisements, just exist " film leader section, advertisement * * .1, medium film section 1, advertisement section * * .2, medium film section 2, advertisement section * * .3 and reel end section " structure;
Wherein " * * " be version number.The advertisement hop count that inserts is many more, and issuable version number also will be many more.In the different editions program, have only advertisement section content difference, and the film leader section of each version program, medium film section and reel end section all are corresponding fully the same programme contents.
The issuing way of multi-edition TV program:
One of traditional program issuing way: with the TV programme of each version, be recorded in respectively on the dish Betacam broadcast level tape, then, adopt the method for express mailing, be distributed to various places TV and Radio Service, finally play by various places TV and Radio Service again.This kind issuing way obviously exists following shortcoming:
