Problems solved by technology

The fourth generation is hard disk AV player, including hard disk network player, hard disk PMP (including MP4) player, this generation of AV player has been greatly reduced in terms of volume and power consumption, but it has not provided image clarity. Improve. Just like MP4, its compression rate is very high, and it can store more content under the same capacity, but the quality of playback is actually reduced
Therefore, it can only be applied to pocket type, but cannot reduce power consumption and improve clarity

Embodiment Construction

[0045] The invention consists of a host, a remote controller and a power adapter.

[0046] The host is equipped with USB socket, DC power socket (DCIN), PC display socket (VGA), high-definition TV socket (HDMI), audio terminal, video terminal, S terminal, coaxial cable, optical fiber cable, etc. The host also has There are several buttons, such as play / pause (PLAY / PAUSE), stop (STOP), previous section (PRE), next section (NEXT).

[0047] The main chip U3 adopts HV3428, and U3 has built-in OTG control. Therefore, the circuit connection between it and the USB interface is very simple. The data signal is transmitted through differential input / output. R12 and R13 are current limiting resistors, and R11 and R133 are used to form Voltage divider circuit for USB detection. When there is data transmission and USBVBUS is high level, the inserted device is an active device; when there is data transmission and USBVBUS is low level, the inserted device is a passive device; when there is ...

Abstract

The invention relates to a voice-video player. Wherein, it uses solid memory as storage media; its AV decoder with MCU comprises video processor, bit flow analyzer, DRAM controller, video-image processor, TV coder, voice processor, frame buffer, ATAPI, AV digit signal processor (DSP), FLASH controller, USB, OTG and relative controller; the AV decoder is connected to the solid memory, SDRAM, program memory, AV video output, display interface, DAC voice output, low-pass filter, return circuit, filter, power, and stabilizer. The invention has small volume, light weight, low power consumption, etc. And it is five-generation player, to be matched with high-clear digit TV.

Description

Technical field: [0001] The invention relates to an audio and video playing device. Background technique: [0002] AV players have gone through four generations. The first generation is VCD, which is based on the MPEG1 decoder, and the image resolution is 1 / 4D1; PAL (360 lines × 288 pixels); NTSC (352 lines × 240 pixels). The horizontal resolution is 250 lines. The second generation is SVCD and CVD. It is a product configured with a VCD core and an MPEG2 decoder. It aims to improve the image clarity by increasing the rotational speed of the disc. Image resolution is 2 / 3D1: PAL (480 lines x 384 pixels); NTSC (480 lines x 320 pixels). The horizontal resolution is above 350 lines. The third generation is DVD, which is based on the MPEG2 decoder, and the image resolution is D1: PAL (720 lines × 576 pixels); NTSC (704 lines × 480 pixels). The horizontal resolution is 500 lines. The fourth generation is hard disk AV player, including hard disk network player, hard disk PMP (i...
