Abstract

The invention provides a multimedia signal processing device and a multimedia video-audio system, wherein the multimedia signal processing device comprises a decoding chip, a wireless video signal sending unit, a control signal receiving unit, a code value converting and transmitting unit and a network unit, wherein the wireless video signal transmitting unit is used for coding a video flow decoded by the decoding chip and sending the coded video flow to a wireless signal receiving unit of a wireless television in the mode of wireless transmission; the control signal receiving unit is used for receiving control signals from a remote controller of external multimedia equipment; the code value converting and transmitting unit is used for converting control signals of the remote controller of the external multimedia equipment received by the control signal receiving unit into a code value corresponding to the external multimedia equipment so as to control the external multimedia equipment; and the network unit is used for communication between a video signal from a network and the wireless television through the wireless video signal transmitting unit. By the invention, connecting wires between the multimedia signal processing device or multimedia peripherals and the television can be reduced, and the sense of experience of users can be improved.

Description

technical field [0001] The invention relates to the technical field of television, in particular to a multimedia signal processing device and a multimedia audio-visual system. Background technique [0002] With the continuous development of science and technology, the functions of TV products are increasing day by day. However, due to the limitations of domestic technology and cost, the current TV products still have the following problems: [0003] (1) TV products that meet the definition of multi-function are not ideal in terms of body weight and thinness, which reduces the user's sense of experience; [0004] (2) Due to the increasing number of audio and video devices, when these devices are connected to the TV, more connecting wires bring inconvenience to the user and affect the appearance of the whole home; [0005] (3) The current set-top box can only correspond to one TV set. If there are multiple TV sets, multiple set-top boxes are needed, which increases the cost ...
