The invention integrates DVB, DVD and analog TV set, providing features of low cost, stable performance, and easy of use.

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...
