Abstract

This invention presents the combining idea of the wireless mobile terminal and the digital audio data player. This invention will reduce user's inconveniency with possessing above two products. In this invention, the function of storing digital audio data encoded by MP3 or AAC into the memory and the function of decoding the data to decoded original audio signal are added to a wireless mobile terminal. And using various methods that first method is PC interfacing method to connect with Internet, second method is requesting method of the digital audio data encoded by MP3 or AAC via the public communication network or data network that is wire or wireless channel, third method is passive receiving method of the digital audio data transmitted from station, it is stored the digital audio data encoded by MP3 or AAC into the memory, decoded the digital audio data stored in the memory to decoded original audio signal. As result, using this invented apparatus, it will be implemented convenient mobile services of telephone and audio on demand (AOD) or music on demand (MOD). The main function of the invented apparatus is wireless mobile terminal, additional function is storing and playback of the digital audio data encoded by MP3 or AAC.

Description

Apparatus and method for storing and playing back of Digital audio data on wireless mobile terminal Technical Field

This invention relates to combining technology of wireless mobile terminal and

digital audio data player.

Background Art

We want to communicate with others using wireless mobile terminal or listen to

music using digital audio data player, must take two products inconveniently.

The present wireless mobile terminal for communication is consists of data

transceiving function block, audio signal processing function block and control

function block by keypad. And present portable digital audio data player is consists

of playback module as basic function, data storage module and recording module.

But there are no products providing two functions as single assembly.

Above mentioned the wireless mobile terminal includes cellular phone, PCS

phone, IMT-2000 terminal, GSM terminal, wireless portable handset, hand phone

and mobile phone for wireless communication of audio or data.

Disclosure of Invention

Since it is added the function of storing and playing back of the digital audio

data to the wireless mobile terminal by this invention, selectable usage of the digital

audio player or the wireless mobile terminal is available in this invented apparatus. In this invention, the wireless mobile terminal comprises memory for storing

digital audio data, audio decoder, audio control and display module, audio signal

output module. The memory for storing of the digital audio data is fixed or

replaceable.

There are two method for storing of the digital audio data, first method is PC

interfacing method to connect with Internet, second method is requesting and

receiving method of the digital audio data via public communication network or data

network that is wire or wireless channel, or passive receiving method of the digital

audio data transmitted from station.

The digital audio data that are received and stored into the memory, will be

decoded and played back to the decoded original audio signal using keypad

operation by user's necessity.

In accordance with an embodiment of the present invention, the receiving and

storing method of the digital audio data is as follows;

first, this invented apparatus is connected with public communication network

via wired 2), the digital audio data are inputted to the modem block(16) by user's

keypad operation (17), stored into the memory(19) by the processing of the processor

block(15).

second, operation of the PC(13) connected with public communication network via wire or Internet, provides the modem's block(16) with the digital audio data, this

data will be stored into memory(19) by control of the processor block(15),

third, by the user's keypad(17), requesting and receiving of the digital audio

data via the public wireless communication network, or passive receiving of the

digital audio data transmitted from the audio providing station is performed, and

then the digital audio data are stored into the memory(19),

fourth, the replaceable memory storing digital audio data is inserted and

connected with the data interfacing connector.

The stored digital audio data by above methods will be decoded by

decoder(20) and generated a audio signal to audio output δ) in accordance with

the audio circuit control by the operation of keypad(17).

As result, using this invented apparatus, the mobile services of audio on

demand(AOD) or music on demand(MOD) will be implemented.

Brief Description Of Drawing

FIG. 1 is a block diagram showing the functional configuration of storing and

playing back of Digital audio data on wireless mobile terminal.

Modes for Carrying out the Invention

The storing and playing back partOOO) of the digital audio data is consists of

the digital audio data storage memory(19), audio Decoder(20), selecting control of transceiving that wireless telephone function has priority over audio player in the

case of detecting call signal, audio control and dιsplay(21 ). The processor block(15),

user's controller, key pad(17) and audio output module δ) are common to be used

in the function of wireless mobile terminal and audio player.

In accordance with an embodiment of the present invention, the fresh memory

may be used for storing memory(19) of digital audio data. The memory types

adequate for this embodiment are fixed memory, replaceable or combinational

memory(19) for storing digital audio data. The MP3(MPEG^~1 Layer 3) decoder,

AAC1MPEG-2 Advanced Audio Coding) decoder, or MP3 and AAC decoder(20) are

used for decoding of the digital audio data. The LCD display at present or LCD

displaying selection menu of digital audio data is used as a display module(21 ). And

the selected digital audio data is decoded and the audio signal is outputted to the

audio output device δ) such as speaker or earphone.

The digital audio data comprises music, audio program for language education,

narration and so forth that are coded by the MP3 or AAA coding algorithm.

Industrial Applicability

Using this invention, it will be implemented convenient mobile services of telephone

and audio on demand(AOD) by single apparatus.
