Abstract: A portable communication device supporting video calls is provided. The portable communication device can be configured to perform a video call on the basis of a first video codec and a first audio codec, receive, through a touch display, a request for recording the video call, and, if the first audio codec is not supported by a designated media container, record the video call on the basis of the first video codec and a second audio codec supported by the media container.

Abstract: A method for controlling media reception at an electronic device communicating with at least one external device includes establishing a communication session between the electronic device and the at least one external device via a server; in response to establishing the communication session, creating an instance of a first reception control state machine for controlling multiple media receptions in the communication session; receiving, from the server, a media transmission notification indicating that a media reception is available from an external device; receiving, from a user of the electronic device, an input for permitting the media reception; and in response to receiving the input, transmitting a media reception request requesting the media reception to the server and creating an instance of a second reception control state machine for controlling the media reception.
