Television line, television system and television playing data acquisition method

Abstract

The invention provides a television line, a television system and a television playing data acquisition method. The television line comprises a master chip, a memory, an information receiver, a USB interface and an HDMI interface, wherein the television line is connected to a set top box through the USB interface; the television line is connected to a television through the HDMI interface; the information receiver is used for receiving a first data request sent by a user; the master chip is used for generating a second data request according to the first data request and sending the second data request to the set top box; the master chip is further used for decoding first feedback data returned by the set top box, and sending the decoded second feedback data to the television in order to make the television play second feedback data; and the memory is used for storing the first feedback data and / or second feedback data. According to the television line, the television system and the television playing data acquisition method, the capacity of acquiring data by the set top box is reserved, the data decoding capability is improved by increasing the television line supporting the decoding of multiple data formats, so that the updating cost of the television system is reduced.

Description

technical field [0001] The invention relates to the technical field of television intelligent terminals, in particular to a television cable, a television system and a method for acquiring television broadcast data. Background technique [0002] Digital video conversion box (Set Top Box) referred to as STB, usually called a set-top box or set-top box, is a device that connects a TV with an external signal source. It can convert the compressed digital signal into TV content and display it on the TV. However, with the higher demand for video clarity, the second-generation AVS standard (AVS2) has emerged. The primary application target of this standard is ultra-high-definition video, supporting ultra-high resolution (above 4K), high dynamic range High-efficiency video compression; existing set-top boxes cannot decode and convert videos based on the AVS2 standard, and the cost of replacing a new set-top box is relatively high. Contents of the invention [0003] In view of th...
