Abstract
The present invention relates to a sound device for a digital TV, particularly to a sound device for downloading MP3 music from a computer network by a hard disc of a video recorder of the digital TV. The device is mutually connected with a computer or a network by an MP3 decoder which is additionally arranged, the internet is browsed by a modem, and MP3 music is downloaded from the network. Interfaces of an MP3 file manager and an MP3 player are conveniently made by a powerful perfect OSD (ON SCREEN DISPLAY), and the MP3 music is randomly browsed, updated and played.
Description
Technical field
The present invention relates to a kind of acoustical unit for digital TV set, specifically is the hard disk by digital television recorders, downloads the acoustical unit for digital TV set of MP3 music from computer network.
Background technology
At present the MP3 music is comparatively popular, and its compression ratio is higher, and wide material sources duplicate undistortedly, and expense is cheap, has a large amount of song fans and music-lover.But owing to costing an arm and a leg of MP3 walkman player, and memory space is little, has limited numerous music fans' use greatly.And computer is used as document process mostly, seldom is used as broadcast and the storage of MP3 with it.
DVR (Digital Video Recorder) digital television recorders or PVR (PersonalVideo Recorder) have been the commercial goods.It is that audio signal is carried out depositing hard disk in after the MPEG-2 compression, making full use of hard disk is its greatest feature, because the high speed of hard disk, big capacity, make that the user can realize TV programme time delay, instant playback, the program recording of recording, reset etc., so as to realizing family's TV " program request " center.Its huge hard disk is the natural platform of structure Music center, and a hard disk can be recorded at least 6000 first MP3 songs, even only use a part of space, is used for storing thousands of first songs, and it is required also to be enough to satisfy general family.
Summary of the invention
The object of the present invention is to provide a kind of acoustical unit for digital TV set, can be by the hard disk of digital television recorders, download, storage, playback MP3 music.
The object of the present invention is achieved like this: DVR (Digital Video Recorder) comprising: the tuner that can receive the analog or digital TV signal; To the motion image expert group 2 decoder (MPEG-2 CODEC) that is recorded in hard disk behind the coding audio signal, is convenient to reset after the audio signal of having encoded is decoded; As the microprocessor more than the 100MIPS of real-time processor controls; To the coding audio signal of decoding, so that the audio frequency and video encoder of output different systems audio frequency, video analog signal; Be used to surf the web or download the modulator-demodulator of electronic program guides (EPG); The Advanced Technology Attachment (ATA) that is used for hard-disk interface; The hard disk that is not less than 20GBYTES as medium.In it there be software module of dress: the embedded real-time operating system of customization (OS); The application program and the user interface (high-speed CPU is supported five layers of OSD structure) that comprise various operations, control, human-computer dialogue etc.; The driver of codec chip, Advanced Technology Attachment (ATA) hard disk, card of surfing Internet (MODEN); Generally be used for downloading EPG and be used for browsing the browser that INTER nets.And the present invention only sets up a MP3 decoding device, and interconnected by 25 clock communication interface (DB25) parallel ports and computer.
Effect of the present invention: by this device, utilize modulator-demodulator to browse the Ying Tenaite net, download the MP3 music from the Internet; By powerful perfect OSD (ON SCREEN DISPLAY), make mp3 file manager and MP3 broadcast interface easily, random browses, upgrades, plays.
Description of drawings
Fig. 1 is the schematic diagram of DVR;
Fig. 2 is the theory diagram of an embodiment of the present invention;
Fig. 3 is the theory diagram of the another kind of embodiment of the present invention.
Embodiment
Now in conjunction with the accompanying drawings use of the present invention is elaborated:
Existing many buttons on the remote controller of former DVR, as: menu, upper and lower, left and right, affirmation, deletion, left and right acoustic channels switching, broadcast, F.F., rewind down, stop, recording, time-out and 0-9 numeral etc., only need increase MP3 again and get final product.
On software, increase the driver of mp3 file manager and player and MP3 chip, file management comprises following content: browsing file, retrieval, protection, deletion, preservation.Player is a user interface, following content is arranged: mp3 file menu, multifile play mode, monofile play mode, loop play pattern, record, broadcast, F.F., suspend, stop, deletion, reproduction time demonstration, file size demonstration, programm name demonstration, left and right acoustic channels switching, mega bass switch, volume adjusting etc., whole operation is finished in combined with remote-control device OSD prompting.Remove the MP3 boot files and reside in the mainboard ROM, other program all is placed on the hard disk.
Another embodiment: the AUDIO CODEC in DVR directly supports the compression and decompression of MP3 format, then can not increase the MP3 decoding device, and only increase the mp3 file manager and the MP3 player gets final product, DVR can finish A/V and records and play like this, can be used as digital recorder and MP3 player again, see Fig. 3.
The running of system: press the MP3 key, mainboard CPU switches to data pattern (hard disk generally has two kinds of operating modes among the DVR: A/V stream mode and DATA pattern) with hard disk; Start file manager, the MP3 player of MP3 on the hard disk, drive the MP3 decoding chip simultaneously, make decoding chip import default register value; Stop the work of MPEG-2 decoder; Audio output directly switches refutes the output that meets MP3 decoding device audio frequency D/A, so just performs adequate preparation for playing MP3, promptly is referred to as the MP3 pattern.
In the MP3 pattern; press the recording key of remote controller; system detects the parallel port automatically; high-speed wideband communication interface (IEEE1394), general serial communication interface (USB), Ethernet (ETHERNET) etc.; data if any corresponding format occur, and then journal behind former mp3 file is after has recorded the clear area; automatically deletion do not add protection, recording time A/V program the earliest, and cover its zone.And when recording the A/V program, the A/V program can not cover the MP3 zone.
In the MP3 pattern, press the play button of remote controller, eject the MP3 program guide, and play mode selection, Search Hints, delete button etc. occur on the right side of program guide, can manage and play mp3 file.Also can realize same function by Menu key on the remote controller.After choosing one or more programs, press acknowledgement key, promptly read the MP3 data, input to the MP3 decoding device, after decoder and D/A conversion, export the A/V terminal to from hard disk.
