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.
