2020 is gradually coming to an end, and the analog television that has accompanied several generations of people growing up is about to end. According to the "Notice on the Work Arrangements for the Planned Shutdown of Terrestrial Analog Television" issued by the State Administration of Radio, Film and Television, terrestrial analog signals across the country will be shut down before December 31. This also means that the old "big-butt color TV" and "snow TV" will permanently withdraw from the stage, and will be replaced by the currently popular digital TVs.


The reason why analog TVs are being phased out at an accelerated pace has a lot to do with the evolution of transmission technology. Analog TVs use terrestrial analog signal technology to transmit signals. Due to the disadvantages of analog signal technology such as high loss and susceptibility to interference, the picture quality of analog TVs is generally not high. Digital TVs use data compression technology to transmit signals, and the decoding capabilities of TV chips can restore images and sounds. The entire process can greatly reduce signal interference and loss problems.


TV chips largely determine the upper limit of a digital TV's picture quality, and MediaTek's TV chips are the industry leader. Take its industry-leading 8K TV chip S900 as an example. It can achieve up to 8K 60Hz/4K 120Hz picture quality display, and also supports DTS sound effects and Dolby Atmos. For analog TVs, none of the above can be achieved.

 

At the same time, when TV chips are combined with AI technology, digital TVs can achieve a qualitative leap in viewing experience. MediaTek has long integrated AI technology into TV chips, which can achieve AI-PQ picture quality enhancement, AI SR super resolution, AI intelligent voice function, and more.


The AI-PQ picture quality technology supported by MediaTek TV chips can realize scene and face recognition, and improve the picture quality in real time by optimizing color saturation, brightness, clarity, image noise and dynamic motion compensation, giving the TV screen a better visual effect.

 

AI SR super resolution can achieve intelligent adaptation of the resolution of streaming media, cable TV signals or disc content. Through powerful AI computing power, it can identify the scene and image of the picture, adjust the noise and clarity of each frame of the picture, and thus improve the image quality in real time.

 

AI intelligent voice allows digital TVs to abandon remote controls and be controlled through AI voice, interacting with smart applications such as smart search, making digital TVs more intelligent.


The addition of the above AI technologies has created an epoch-making difference between digital TVs and analog TVs, accelerating the exit of analog TVs. The shutdown of analog signals means that digital TVs have completely replaced analog TVs. To date, 2 billion digital TVs have adopted MediaTek's TV chip solutions, which provide users with a rich home entertainment experience through powerful chip performance and technology. With the support of powerful AI technology, it not only brings truly intelligent applications to digital TVs, but also helps digital TVs move towards the intelligent era.
