Audiovisual entertaining system and its detachable display device

Abstract

The display device is secured in a carrier by dual-locking; through the access point in the carrier, the display device wireless exchanges data with different media centers. The dual-locking can be unlocked by using single hand.

Description

technical field [0001] The invention relates to an audio-visual entertainment system and its detachable display device, in particular to a wireless audio-visual entertainment system and its detachable display device. Background technique [0002] The display devices of audio-visual entertainment systems sold in the market today are mostly fixed in a fixed place in an embedded manner, so they cannot be easily separated. For example, the liquid crystal display device (LCD) traditionally arranged on the headrest of a car cannot The ground is separated from the headrest, so it must be placed on the car for a long time; in terms of security, whether it is a car or a liquid crystal display device, it is easy to be stolen. In addition, the mechanical design of traditional automotive liquid crystal display devices will also be difficult to disassemble when repairing; moreover, if it cannot be easily disassembled or carried, then such a display device will also be difficult to upgrad...

AI Technical Summary

Problems solved by technology

This kind of embedded display device has an obvious disadvantage, that is, it needs to connect various lines during installation, which makes it difficult to install and maintain

[0006] In addition, the disadvantage of the existing known wired audio-visual entertainment system is that users of each liquid crystal display device can only enjoy the same audio-visual program at the same time, and the playback host system is performing rewinding, forwarding, selecting segments, pausing, playing, etc. , Stop, etc., when playing control, each LCD device operates synchronously, so at the same time, only one of the multiple users can perform playback control, except for the operator who controls the playback setting options, the rest Users can only passively enjoy the set programs

[0007] Due to the wired configuration of each device in the existing audio-visual entertainment system, it cannot be applied or combined in a variety of ways, especially the embedded display device in the audio-visual entertainment system, if it cannot be easily disassembled or Carrying it elsewhere makes it impossible to easily upgrade the system or the display itself, or integrate it with other technologies or devices, such as wireless local area networks (WLANs) and multimedia players

Therefore, under the old system architecture, it is impossible for every liquid crystal display device user to select the programs they like to enjoy and operate according to their own preferences, and to perform playback control, and it is also impossible for users to freely view the The audio-visual entertainment system or the display device in the system is used in different places, and it is impossible to combine the display device with other expansion devices to achieve the purpose of high-efficiency use
