Abstract

The invention discloses a mobile high-definition link (MHL) realizing method, which comprises the steps of: detecting whether a function of a remote controller for selecting a USB (Universal Serial Bus) interface is a MHL function by a system chip; if so, outputting an MHL control signal, controlling a signal switch to gate an MHL function channel and send an MHL signal to an MHL chip; after the MHL chip converts the received MHL signal into an HDMI (High-definition Multimedia Interface) signal, sending the HDMI signal to the system chip; and receiving and processing the HDMI signal by the system chip. The invention further discloses a video playing device, wherein a common USB interface of the video playing device is compatible with the MHL function, so that the performance of the video playing device is improved, the user experience is promoted, and the use cost of users is reduced.

Description

technical field [0001] The invention relates to the field of video playback, in particular to a method for realizing mobile high-definition connection and a video playback device. Background technique [0002] Based on the current emerging MHL (Mobile High-Definition Link, mobile high-definition connection) technology, mobile phones, PAD (Pure Audio Design, tablet computer), digital cameras, digital video cameras, portable digital players and other devices will open the era of MHL technology, corresponding Certain video playback devices such as televisions have also added MHL functions. [0003] For video playback devices with MHL functions on the market, because HDMI (High-Definition Multimedia Interface, high-definition multimedia interface) is more advanced and convenient than traditional DVI (Digital Visual Interface, digital video interface), therefore, the current market The video playback devices with MHL function on the Internet basically use the HDMI interface, and...
