Abstract

The invention provides an HDMI and MHL input compatible type transfer device and a head-mounted display apparatus, and pertains to the technical field of signal transfer. The HDMI and MHL input compatible type transfer device comprises: an HDMI input interface for inputting an HDMI signal; an HDMI-to-MHL chip which is connected with the HDMI input interface for converting the HDMI signal received from the HDMI input interface into a MHL signal; an HDMI-to-MHL output interface which is connected with the HDMI-to-MHL chip for outputting the MHL signal converted by the HDMI; a MHL input interface which is connected with the HDMI-to-MHL output interface for receiving the MHL signal and transmitting the MHL signal; and a MHL cable which is connected with the MHL input interface for transmitting the MHL signal. According to the invention, advantages of simple structure and reasonable cable configuration can be realized, through the HDMI-to-MHL chip, an HDMI signal can be converted into a MHL signal, and the MHL signal can be transmitted to the mainboard of the head-mounted display apparatus through the MHL cable, so not only the HDMI signal and MHL signal input compatibility can be realized, and but also the overall weight of the head-mounted display apparatus can be reduced because the MHL cable has the advantage of reduced occupied space and has the advantage of less weight compared with an HDMI cable.

Description

technical field [0001] The invention belongs to the technical field of signal switching, and in particular relates to a switching device compatible with HDMI and MHL input for a head-mounted display device and a head-mounted display device. Background technique [0002] HDMI, that is, High Definition Multimedia Interface (English: High Definition Multimedia Interface) is a digital video / audio interface technology. It is a dedicated digital interface suitable for image transmission. It can transmit audio and video signals at the same time. The maximum data transmission speed is 5Gbps. At the same time, there is no need for digital / analog or analog / digital conversion before signal transmission. MHL, that is, mobile terminal high-definition audio-visual interface (English: Mobile High-Definition Link), is an audio-visual standard interface connected to portable consumer electronics devices. It uses the existing Micro USB interface, because of its high-speed signal transmission...
