Description

  The present invention relates to a movable audio streaming and logging apparatus, and more particularly, to a small apparatus that is easy to move and has a digital audio streaming function and an audio logging function at the same time.

With the spread of the Internet, many audios, that is, televisions and radio stations, are gradually installing programs and contents in the network to provide information to more users. By connecting to a PC and the Internet, these audio streams can be obtained, and the user can receive audio information in a remote state. You can enjoy the video. Cables and radio waves that were necessary to receive and listen to high-quality audio broadcasts at the same time are now obstacles for simultaneous reception around the world. Reception becomes difficult. Therefore, the spread of audio over the Internet has been developed, so that it can be viewed regardless of distance.

However, the disadvantage is that when users receive these audio streaming, they now rely on a connection to a personal computer or network, and if they want to carry or travel frequently, they can use a notebook computer or other portable electronic device. The only thing that depends on the device is that the audio streaming playback function must be provided for both portable and fixed devices. In other words, it is still inconvenient for the user to carry it, and even when other functions are unnecessary and only the reception of audio is necessary, it can not be received without arranging one computer. If so, it can be said that it is very useless.
In view of the above-described drawbacks, a mobile audio streaming and logging apparatus according to the present invention is provided which can enjoy desired audio at any time independently from a personal computer or the like so as to be portable.

To connect to the Internet via a wired or wireless interface to access the audio streaming servers around the world, and to play the information provided by these audio streaming servers, Programmable elements can be used to update the system from time to time, and by adopting a CPU with adequate memory and computing capacity, the user can record the desired server access site, and the corresponding coding calculation method In order to achieve the purpose of audio streaming signal output and logging, combining the proper operation between CPUs.

The audio streaming output 5 of the apparatus 1 is a built-in or external digital or analog audio output signal, and the user can select the audio streaming signal and output the audio streaming signal.

The player 1 in the present invention includes several important devices. One is a net connect port 6 of the Internet 2, and the net connect port 6 is a wired connection method or a wireless connection method. After receiving an audio streaming connection signal at the connect port 6, the FPGA 7 provided in the system performs a preprogrammed operation to provide a decoder for the received audio streaming format. The decoder is a memory space 8 in the FPGA 7 or in the device. The memory space 8 is completed by an arbitrary non-volatile memory, or uses a volatile memory. Specifically, the FLASH Memory And SDRAM (Synchronous Dynamic Random Access Memory), etc., together with the digital signal processor (DSP) 9, the received audio streaming is decoded, and the decoded signal is output in the required output format,
If analog output is necessary, the decoded digital audio signal is sent to a digital to analog converter (DAC) 10 and converted to analog to perform analog audio output 11. After converting the digital signal into an analog signal, the analog signal is transmitted to the internal built-in 12 or the analog audio output 11 such as a circumscribed type speaker or earphone, and the screen. Measures for projecting internal and external audio signals and audio signals are analog 11, built-in analog audio output 12, built-in analog audio output 13, and digital audio output 14 types.

  In addition to storing the decoder, the memory space 8 in the present apparatus 1 provides a storage space for the site of the audio streaming server 3 and is connected via the Internet 2, and the site of the audio streaming 3 is connected to the central server 4. to download. The memory space 8 can be updated at any time according to the needs of the user, and the updated contents are not limited to the decoder, the site of the audio streaming server 3, etc., but the memory function required by the other system in the device 1 It is good also as what provides.

  Audio streaming logging is performed by an encoder in the apparatus 1 or by a direct logging method. In the audio input interface, in addition to the Internet 2, a standard type audio input interface 15 that is usually used may be provided, which includes a microphone, an AV terminal, and the like, and provides an audio input interface. Logging data is stored in the memory space 8 so that it can be repeatedly reproduced later. When the signal of the audio input is an analog signal, the analog signal is converted into a digital signal through the ADC analog-digital converter 16 so that the FPGA 7 or other elements in the apparatus can meet the needs.

  As shown in FIGS. 3 and 4, the apparatus 1 is provided with one or more display screens 17 to display the site of the audio streaming server 3, and the user makes a selection with the operation button 18, or receives an audio streaming signal. The nest pre-play and regeneration status shall be selected. In addition, the wireless connection interface 19 and the wired connection interface 20 are connected to the Internet 2, and the display device includes each indication light, which includes a signal light 21 indicating the strength of the signal, a streaming status light 22, and a power source. A power supply instruction light 23 indicating the supply state is included. The user adjusts the volume output by the volume control 24, the volume and audio are output from the video input 25 and the audio input 26, and the power supply is output from the battery and the power input 27.

  This device 1 is connected to the Internet 2, but is connected to a wired or wireless network connection port 6 and the protocol is TCP / IP or other protocol, which transmits audio streaming data on the carrier audio. It is only necessary that the audio streaming server 3 and the central server 4 can be localized. That is, in addition to the connection of the wired network, the current wireless network environment, that is, Bluetooth, 802.11, IrDA, or the like can be used as an intermediary for connecting the device 1 and the network 2. The user's access environment settings are stored in the memory space 8 in the apparatus, and need not be set every time, and settings that are correlated later may be selected. These connection mediators are used singly or in parallel, and when two or more types of connection methods are adopted, the transmission media determined by the user can be used through user settings.
