In present television set design, it all is the separately design of television set that causes different audio frequency and video coffrets to above-mentioned two kinds towards different markets, so just need two groups of different designers, produce two different main frame central layer TVs, the company that makes all can increase cost at the production tissue, aspect safeguarding, cause the efficiency of operation of whole company to reduce, increased the cost of product.
Summary of the invention
Technical problem to be solved in the utility model is, at current two kinds of different audio-video coffrets, the RCA interface need separately design two different main frame central layers with the SCART interface, the cost height, and the problem that production efficiency is low proposes compatible audio frequency and video coffret.
The technical scheme that the utility model solve the technical problem employing is, compatible audio frequency and video coffret is made up of the RCA interface, the corresponding arrangement of pin of the pin of described RCA interface and SCART interface.
The beneficial effects of the utility model are, a kind of compatible audio frequency and video coffret is provided, utilize a main frame central layer to finish the television main central layer design of RCA interface and two different audio-video coffrets of SCART interface, reduced the exploitation of two kinds of different markets television sets and the developer and the development time that need, reduced television main central layer quantity, save production cost, improved production efficiency.
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
