Apple has shown continued interest in improving the Bluetoothwireless standard, making it more power efficient when convertingstreaming media to a compatible format. The details come from a patent application discovered this week by AppleInsider first filed in December of 2008, but re-filed as a continuationwith the U.S. Patent and Trademark Office in February of this year.The filing, entitled "Data Format Conversion for ElectronicDevices," notes that converting data to a new format can be apower-hungry process. Portable devices, such as an iPhone or iPod touch, can convertmedia files stored in a compressed format to a Bluetooth-compatibleformat. This allows the device to wirelessly transmit media to anexternal device, such as a Bluetooth headset.
"The format conversion performed by the portable electronic devicemay quickly drain the energy stored in its battery," Apple's filingreads. "Therefore, it would be desirable to provide anenergy-efficient technique for converting data to aBluetooth-compatible format." Compression of data is necessary with Bluetooth because thetechnology has a limited transmission throughput. TraditionalBluetooth converters fully decode and re-encode compressed data,which can be taxing on a device. Apple's solution aims to "significantly lower" the number andcomplexity of computations executed in transmitting media overBluetooth. Its proposed invention includes a dedicated formatconverter that could take a media file and produce data in aBluetooth-compatible format in a more energy-efficient manner.
This format converter could include a band separation module, a bitallocation unit, conversion modules, and quantizers, that woulddecompose the frequency domain information of a file, such as AACaudio, and turn it into a plurality of data streams comprised ofdifferent sub-bands. The format converter would then transform each data stream to a newencoding scheme, and then quantize the streams based on bitallocation for each sub-band. The included bit allocation unitwould compute information for each sub-band based on an unfilteredversion of the compressed data. "The format converter can convert each data stream into a formatcompatible with Bluetooth," the application states. "ForAAC-encoded files, for example, the format converters can convertthe MDCT-based data into a format that uses a different frequencytransform-based compression algorithm (e.g., DCT-based algorithm).
"Then... the format converter can assemble the transformed datastreams into frames of appropriate sizes for Bluetoothtransmission, and may perform other functions necessary to preparethe transformed data streams for transmission over a Bluetoothlink." The proposed invention, re-filed with the USPTO on February 6 ofthis year, is credited to inventor Jeff Bush. Apple's continuing interest in improving the Bluetooth wirelessstandard is evidenced by a separate filing from last October discovered by AppleInsider that described a new way to power off Bluetooth-enabled electronicdevices. Apple's proposed method would allow users to press justone button on one device to configure or disable multiple devices. Apple also joined the Bluetooth Special Interest Group Board ofDirectors last June , when it was revealed that Apple is aiding in developing thelow-power Bluetooth 4.0 specification.
Most of Apple's latestproducts, including the new iPad and iPhone 4S, also offer supportfor Bluetooth 4.0. I am an expert from Furniture & Furnishings, usually analyzes all kind of industries situation, such as glider rocker cushions , glider rocker chairs.
