A system and a method for monitoring a video communication device configured to monitor an activation state of a video capturing module are provided. A detection circuit is configured to detect an operation current input to the video capturing module. A control circuit is electrically connected to the detection circuit and determines whether the video capturing module is activated according to a magnitude of the operation current.

System and method for monitoring video communication device

A multimedia playing system is provided. A portable electronic device includes a first dock port, a second dock port, a power module, an audio processor and a controller. When a first single-ear wireless earphone connects with the first dock port, the power module charges the first single-ear wireless earphone via the first dock port. When a second single-ear wireless earphone connects with the second dock port, the power module charges the second single-ear wireless earphone via the second dock port. The audio processor provides a left sound channel signal and a right sound channel signal. When the first single-ear wireless earphone separates from the first dock port, the controller provides one of the left sound channel signal and the right sound channel signal to the first single-ear wireless earphone according to a relative position between the first dock port and a user.
