Problems solved by technology

However, if Figure 5 As shown, if the audio player is continuously transmitting packets of music streaming data during a particular time slot, the transmission of page commands from the handsfree device to the requesting cell phone may occupy the BT communication bandwidth, thus interrupting the audio playback from the Transmitting music streaming data and causing the handsfree device to suspend receiving music streaming data
As a result, the user using the hands-free device may be disturbed and uncomfortable due to the interruption of music reproduction by the hands-free device

Embodiment Construction

[0015] Associated below Figures 1 to 4 , to describe a vehicle hands-free device (hereinafter referred to as a hands-free device) in the form of applying the present invention. A hands-free device is provided in the passenger compartment of the vehicle, and the hands-free device has a Bluetooth (Bluetooth, registered trademark) communication function. In the following description, Bluetooth is referred to as BT for short. The hands-free device 1 includes a control unit 2 (control unit in the claims), a BT interface unit 3 (short-range wireless communication unit in the claims), a sound processor 4, a memory unit 5, a display control unit 6, and a touch operation Enter unit 7. The control unit 2 has a CPU, RAM, ROM, and an input / output (I / O) bus, and controls overall operations such as a communication operation and / or a data management operation of the hands-free device 1 .

[0016] The BT interface unit 3 can simultaneously establish a plurality of BT connection links (sho...

Abstract

The invention relates to a streaming data playback apparatus. A handsfree apparatus performs an operation for requesting a connection of a Bluetooth connection link to a cellular phone after guaranteeing a continuous playback of music streaming data by an audio player in a time slot that does not have packet transfer of the music streaming data, if the connection request of the Bluetooth connection link to the cellular phone is generated during a time of A2DP connection that defines packet transfer of the music streaming data with the audio player. The connection request of the Bluetooth connection link to the cellular phone is thus handled appropriately without interrupting a continuous playback of the music streaming data.

Description

technical field [0001] The present invention mainly relates to a streaming data reproducing device having a short-distance wireless communication function. Background technique [0002] As one of Bluetooth (registered trademark: hereinafter referred to as "BT") standard communication protocols, Advanced Audio Distribution Profile (A2DP) can be used to control packet transmission of streamlined music data. For example, as shown in Japanese patent document JP-A-2003-309541, A2DP adopts sub-band coding (SBC) format, MP3 (MPEG audio level 3) format, Adaptive Transform Acoustic Coding (Adaptive Transform Acoustic Coding) format, etc. Compress data in packet units to transmit music streaming data. [0003] Configure a BT device with a BT communication function to: when a BT device generates a request for a BT connection link, continuously send a page command to the requesting BT device until the requesting device responds to the page command, or, for example, in 5.12 Seconds pre...
