The invention discloses a high-definition video signal generator and a signal generating method thereof An MCU (Micro-programmed Control Unit) module acquires parameters set by a user through a man-machine interface module to generate a driving parameter sent to each module; a clock generating module generates a corresponding clock signal according to a clock driving parameter from the MCU module and transmits the corresponding clock signal to a video signal generating module to serve as a reference clock; the video signal generating module generates a corresponding video signal according to the reference clock and a video driving parameter from the MCU module and transmits the corresponding video signal to an HDMI (High-Definition Multimedia Interface) sending module; the HDMI sending module converts the video signal into an HDMI signal according to an HDMI driving parameter from the MCU module and sends the HDMI signal; furthermore, an audio signal generating module generates an audio signal according to an audio driving parameter from the MCU module and transmits the audio signal to the HDMI sending module The output parameter characteristic of the video signal can be optionally set by the method, and the application range of the signal generator is widened

High-definition video signal generator and signal generating method thereof

The embodiment of the utility model discloses a digital media adapter which is used for conveniently accomplishing switching of a portable audio/video player to HDMI (High-Definition Multimedia Interface) equipment. The digital media adapter comprises a media activation module, an image conversion module, an audio conversion module, an output conversion module and a control module; the media activation module is used for sending authenticating commands to a media terminal; the audio conversion module is used for converting analog audio signals into digital audio signals; the image conversion module is used for converting analog image signals into digital image signals; the output conversion module is used for converting acquired digital audio signals and digital image signals into digital video signals and outputting the digital video signals; and the control module is used for sending control commands to the audio conversion module, the image conversion module and the output conversion module respectively.
