Set top box 4K video play system

Abstract

The present invention discloses a 4K video play system. An encoding signal receiving module, a decoding module, a decoding signal transmission module and a power supply module are arranged in a box-shaped body 1 and are connected with a video play device through a 4K video connection line 2 so as to allow the whole 4K extension device to be expressed in a wire rod appearance mode, power supply isperformed through a USB port of a current set top box and various encoding signals are transmitted to the encoding module to allow the users to conveniently and simply upgrade and avoid the user desktop is too messy due to too many wire bars; besides, the current set top box is fully utilized to reduce the amortization cost, achieve the repeat usage of the set top box with a laggard performance and reduce the user upgrading cost.

Description

technical field [0001] The invention relates to a set-top box 4K video playback system. Background technique [0002] A set-top box is a device that connects the TV to an external signal source. It can convert the compressed digital signal into TV content and display it on the TV. Signals can come from cable, satellite dishes, broadband networks, and terrestrial broadcasts. The content received by the set-top box is to receive digital content, including electronic program guide, Internet web pages, subtitles, etc., in addition to the images and sounds that can be provided by analog TV. It enables users to watch digital TV programs on existing TV sets, and conduct interactive digital entertainment, education and commercial activities through the network. [0003] With the development of technologies such as photography, video production and broadcasting, the definition of TV programs is getting higher and higher, and the resolution of the video source of TV programs has re...

Problems solved by technology

[0003] With the development of technologies such as photography, video production and broadcasting, the definition of TV programs is getting higher and higher, and the resolution of the video source of TV programs has reached 4K, while traditional set-top boxes do not support the decoding and playback of 4K videos. , the user needs to exchange for a set-top box that supports 4K, which costs a lot

[0004] In addition, existing radio and television network providers generally amortize set-top boxes to users. However, when users have 4K viewing needs, if they directly replace 4K set-top boxes, the original set-top boxes have not yet been amortized, which will lead to multiple amortization. sales problems, bringing high cost pressure to radio and television network providers

[0005] The existing solution is to connect an external 4K hard solution expansion device, but the existing 4K hard solution device requires an independent power supply, takes up a lot of space, and requires various cables for connection, which easily leads to messy desktops and poor user acceptance
