Between its popularity and the demand for wireless headphones, Bluetooth is about to be extended to carry high quality stereo audio signals with the introduction of A2DP -- Advanced Audio Distribution Profile.</DIV></div></div><hr size="2" color="#666666" /><div style="padding: 10px;"><div style="text-align:left;"><DIV>Low quality audio was necessary in the first version of Bluetooth for reliable transmission to mobile phone headsets, because that market was rightly picked to drive the uptake of the technology. Now, consumer demand for wireless everything has meant high quality wireless audio has to be provided, and because you can’t change the reliable, low quality handset profile in Bluetooth, the A2DP profile has been created to compliment it by providing the bandwidth to send high quality audio.</DIV></div></div><hr size="2" color="#666666" /><div style="padding: 10px;"><div style="text-align:left;"><DIV>This is what will power the next wave of Bluetooth headphones, and is being called Stereo Bluetooth by Motorola to avoid consumer confusion. In essence, Bluetooth’s available bandwidth is divided between two layers, a data layer and a voice layer. Mobile phone headsets use the voice layer -- a small amount of dedicated bandwidth. All other Bluetooth communication happens through the much wider data layer. A2DP sets aside a section of the data layer and sends high quality audio through it.</DIV></div></div><hr size="2" color="#666666" /><div style="padding: 10px;"><div style="text-align:left;"><DIV>Bluetooth has high expectations to live up to due the accessorisation it has brought to technology. Consumers are demanding wireless music playback from MP3 players, and since the voice profile won’t let headsets deliver it to them, A2DP has fudged the underlying rules of Bluetooth audio transmission to let them.</DIV></div></div></div></div><br><div style="margin-bottom: 40px;">Tags: <a href="http://clipmarks.com/tags/mobile/" rel="tag">mobile</a>, <a href="http://clipmarks.com/tags/a2dp/" rel="tag">a2dp</a>, <a href="http://clipmarks.com/tags/technology/" rel="tag">technology</a>, <a href="http://clipmarks.com/tags/latest/" rel="tag">latest</a>, <a href="http://clipmarks.com/tags/bluetooth/" rel="tag">bluetooth</a></div>http://www.pcauthority.com.au/feature.aspx?CIaFID=1425Thu, 01 Feb 2007 08:43:32 GMT
