Description

【Technical field】 [0001] The design of the invention relates to the technical field of televisions, in particular to a three-in-one television. 【Background technique】 [0002] The existing analog color TVs in the world were developed under the condition of being compatible with black and white TVs, and their definition and bandwidth applications are greatly limited, and there are problems such as multiple copying, low definition, flickering, bright colors, and remote viewing. Disadvantages of distance propagation and poor anti-multipath interference ability. From the perspective of spectrum application, analog PAL TV can only transmit one analog video signal and one audio signal within the 8M bandwidth. [0003] Digital TV converts traditional analog TV information into binary digital information, then processes it, receives, decodes, converts it into AV signals, and transmits them to every household through the existing wired network. Digital TV is the product of TV digit...

Problems solved by technology

In our country, some cities have started DVB digital signal transmission tests, but there is no product that integrates DVB, DVD, and analog TV in the market. It cannot meet people's growing cultural life needs and the need to play multiple program sources through TV; on the other hand, if you want to realize the above functions, you can only purchase a set-top box and a DVD player, which not only takes up a lot of space, but also costs a lot.
