Detailed ways

The utility model is an integrated multimedia device, which integrates the optical drive and the slot of the portable storage device on the TV, which makes the TV more versatile in use, and does not need an external card reader or optical drive like the traditional TV , to reduce the space occupied during use, and effectively overcome the problem of messy wiring in the past.

Please refer to shown in Fig. 1, this integrated multimedia device comprises a TV 12, is provided with two signal receiving interfaces 14 in this TV 12, and these two signal receiving interfaces 14 can receive an audio-visual signal, and this audio-visual signal is an analog signal or digital signal, and the two signal receiving interfaces 14 are respectively the Federal Television Standards Committee (NTSC) interface and the AV terminal interface, and this signal receiving interface 14 can also be selected from line phase interleaved (PAL), high-definition television (HDTV) in addition One of the group consisting of component input terminal, S-V terminal and digital visual interface (DVI).

In addition, this TV 12 is provided with a suction-type CD-ROM drive 16. The notch of this suction-type CD-ROM drive 16 is exposed from the surface of the TV 12 housing to provide a disc 18 to suck in. This disc is a general radius of 12 centimeters or 8 centimeters of optical discs, the format of its disc 18 is one of them selected from the group formed by DVD, VCD, CD and MP3; The notch of the slot 20 is also exposed on the shell surface of the TV 12. The storage device slot 20 can be inserted into a storage device 22. The storage device 22 is a memory card or a portable hard disk, wherein the portable hard disk is for a million It uses a serial bus (USB) interface type, and the memory card is selected from a digital security memory card (Secured Digital, SD), a multimedia card (Multimedia Card, MMC), a smart media card (Smart Media, SM), an MS card ( MemoryStick), flash memory card (Compact Flash, CF), XD Picture memory card and micro-hard disk (Micro Drive), and most of the data stored in the disk 18 and storage device 22 These are image files, sound files, and audio-visual files.
