Embodiment Construction

[0026] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The traditional stereo sound effect requires that the position relationship between the two speakers and the listener is an equilateral triangle or an isosceles triangle, that is, there is an emperor position, which is the best listening point. After adopting the virtual surround sound technology, it is no longer necessary to accurately consider the placement of the speakers. The stereo surround sound effect can be achieved by virtualizing the left and right channels at a fixed position, but there is still the limitation of the emperor's position. In this embodiment, the position information and the head width information of the viewer are identified in real time by the sensor, HRTF is determined, input to the virtual surround sound calculation module, and the virtual channel data is calculated so that the listener...

Abstract

The invention relates to a method for adjusting the best virtual sound channel of a TV loudspeaker according to the viewer's position and the TV. The method includes: sensing the viewer's displacement and head width in real time; processing the perceived information with face recognition technology, and when the face is recognized, detecting the viewer's orientation information and head width information; based on this information, finding The closest to the actual viewer and its position, query the corresponding head-related transfer function HRTF; calculate the virtual channel data according to the original channel data of the TV and the HRTF, and the virtual channel data is played through the speakers of the TV. The invention solves the problem that manual setting of the emperor position and parameters is required, can adaptively adjust the virtual channel corresponding to the best listening area, and automatically adjust parameters, which is beneficial to improving the effect of users watching TV.

Description

technical field [0001] The invention relates to the technical field of television virtual sound channels, in particular to a method for adjusting a television virtual sound channel according to a viewer's position and a television. Background technique [0002] The traditional stereo system relies on placing multiple speakers in the space to simulate the actual sound field. The placement of the speakers has higher requirements, and it has the "emperor position" that is the best listening area. From the speaker, it lacks 3D stereoscopic and spatial sense, and the cost is relatively high. The development of virtual surround sound technology processes stereo signals according to the sound transfer function HRTF of the human auditory system to reproduce 3D sound effects. The most representative 3D stereo technology, SRS, can obtain the effect of surround sound by using two speakers. With its relatively low cost, it is widely used in TVs, audio players and other products. Howev...
