1. An apparatus comprising:
- a memory;
an antenna;
a communication unit operatively coupled with the antenna and adapted to transmit a signal to an external electronic device using the antenna via a wireless local network; and
a control unit operatively coupled with the communication unit, the control unit adapted to;
operate in a first state during a first portion of a specified period of time, the operating in the first state including transmitting, using the communication unit, at least one portion of multimedia data stored in the memory to the external electronic device via the wireless local network continuously during the first portion of the specified period of time, andoperate in a second state during a second portion of the specified period of time immediately after an elapse of the first portion, the operating in the second state including transmitting, using the communication unit, time information indicative of a length of the specified period of time to the external electronic device via the wireless local network during at least one subportion of the second portion of the specified period of time and refraining from transmitting a portion of the multimedia data to the external electronic device via the wireless local network during the second portion of the specified period of time.
