Home gateway and digital television as well as method for selecting programs by remotely controlling home gateway

Abstract

The invention relates to a home gateway comprising a CPU master processor, a storage module, an intelligent card module, a remote control module, a digital television signal receiving module, a demultiplexer and a descrambling module, wherein the storage module, the intelligent card module and the remote control module are connected with the CPU master processor; and the digital television signal receiving module, the demultiplexer and the descrambling module are sequentially connected. A digital television comprises a television module, a digital television decoder and a receiving and sending unit. A method for selecting programs by remotely controlling the home gateway comprises the following step of: sending a remote control signal sent by a remote controller to the home gateway through the digital television, wherein the digital television sends a selected digital television program signal to the digital television according to the remote control signal. The invention solves the problems of multiple link circuits positioned between the home gateway and the digital television and high requirements for transmission rate and selects the programs by controlling the home gateway through the remote controller of the digital television; and besides, the invention can simultaneously support a standard-definition television and a high-definition television.

Description

technical field [0001] The present invention relates to a home gateway, a digital TV, and a method for selecting programs by remote control home gateway. Background technique [0002] At present, most users watch digital TV programs by transmitting analog signals to the TV through a set-top box, that is, video cables and audio cables are required to transmit the output analog color image signals and audio signals to the TV. With the continuous promotion of smart homes, home gateways have begun to be widely used. The home gateway can integrate the function of the set-top box, but if the home gateway directly outputs the decompressed standard definition or high-definition TV signal to the TV, the digital image signal requires a high transmission rate, which cannot be effectively or high-quality transmission on the channel. In addition, the set-top box is generally placed in the same room as the TV, and it is easy to use the remote control to control the set-top box to select ...

Problems solved by technology

The home gateway can integrate the functions of the set-top box, but if the home gateway directly outputs the decompressed standard definition or high-definition TV signal to the TV, it cannot transmit effectively or high-quality on the channel due to the high transmission rate required by the digital image signal

In addition, the set-top box is generally placed in the same room as the TV, and it is easy to use the remote control to control the set-top box to select TV programs. However, because the home gateway needs to connect to multiple devices, it may not be placed in the same room as the TV. Gateway to select TV program method
