A method for sending a long-term reference picture indicator by an electronic device is described. A long-term reference picture indicator is generated. The long-term reference picture indicator is sent. An absolute Picture Order Count (POC) corresponding to a long-term reference picture is generated. The absolute POC includes a least significant bit (LSB) value. The LSB value of the absolute POC corresponding to a long-term reference picture is sent. A used by current picture flag corresponding to a current picture is generated. The used by current picture flag in at least one parameter set is sent.
