DEVICE FOR PLAYING AUDIO AND VIDEO

摘要

The embodiments of the present application provides a device for playing audio and video, including a processor, a video format conversion bridge chip, a data conversion chip and a motion-compensated frame rate converter, wherein the processor is provided with an on-screen display menu (on-screen display) function module, is configured to produce on-screen display menu data; the video format conversion bridge chip is configured to receive external video signal from an external signal source and convert the data format of the external video signals, and then process the external video signals into high resolution and high frame rate video signals through the motion-compensated frame rate converter; while the data conversion chip is configured to transmit the on-screen display menu data transmitted by the processor to the motion-compensated frame rate converter to superpose, thus presenting the high resolution and high frame rate video signals having on-screen display menu data on a display screen.

主权项

1. A device for playing audio and video, comprising: a processor, a video format conversion bridge chip, a data conversion chip and a motion-compensated frame rate converter, wherein,
the processor which is provided with an on-screen display menu function module, is configured to produce on-screen display menu data; the video format conversion bridge chip, which is coupled to the processor and an external signal source respectively, receives and converts the data format of external video signals from the external signal source, and transmits the converted external video signals to the motion-compensated frame rate converter; the data conversion chip, which is coupled to the processor and the motion-compensated frame rate converter respectively, receives the on-screen display menu data from the processor and transmits the on-screen display menu data to the motion-compensated frame rate converter when the video format conversion bridge chip receives the external video signals, and selectively converts the data format of the on-screen display menu data; and the motion-compensated frame rate converter, coupled between the video format conversion bridge chip and a display screen, superposes the converted external video signals on the on-screen display menu data received and transmits the superposed external video signals to the display screen.
