performing the play control for a played media according to the JumpTo media play control command by the Bluetooth play device.

2. The method according to claim 1, wherein, a trigger condition of sending the JumpTo media play control command by the Bluetooth control device comprises:

inputting a time which is required to jump to play on the Bluetooth control device;

or,

sliding a process bar on the Bluetooth control device to the time which is required to jump to play.

3. The method according to claim 1, wherein,

the extended protocol message is an extended instruction, a manufacturer custom operation (Vendor Unique), of a PASS THROUGH which is based on a protocol standard, a filling action in the extended instruction is defined as JumpTo, and a time parameter carried is the time to jump to play.

4. The method according to claim 1, wherein, the step of performing the play control for the played media according to the JumpTo media play control command by the Bluetooth play device comprises:

a Bluetooth controlled terminal, after receiving the JumpTo media play control command, analyzing the JumpTo media play control command and the time parameter carried by the JumpTo media play control command, and sending the analyzed time parameter directly to a media player, or directly calling an application programming interface of the media player with the time parameter acting as an input parameter; and

the media player, from a time specified by the time parameter, sending media data to a Bluetooth media output module to implement the JumpTo play control for the played media.

5. The method according to claim 4, further comprising:
