Claim:
1. A media transmission method by a media transmission apparatus, comprising: sending a first message, comprising configuration information for media requested by a terminal, to the terminal; sending, to the terminal, a first media packet comprising first data corresponding to a first transport characteristic and second data corresponding to a second transport characteristic; receiving, from the terminal, a second message comprising reception quality information for the first media packet based on the configuration information; and sending, to the terminal, a second media packet comprising the first data in response to determining that a reception status of the terminal is changed based on the reception quality information for the first media packet, wherein the second message comprises a duration for which a reception status of the first media packet was measured, a loss rate of the first media packet received for the duration, an average interval in which two media packets are received for the duration, a time taken to send the first media packet for the duration, a time when the terminal sent a status information message for the duration, a peak bit rate for the duration, and information about buffer fullness remaining in the terminal for the duration which is used in MPEG Media Transport (MMT), wherein a connection between the media transmission apparatus and the terminal is disconnected without notification to the media transmission apparatus upon determining that a reception of the media requested is impossible based on the configuration information, wherein the first message comprising the configuration information includes information about a transport characteristic of the media and information about a method of sending reception quality information for the media, and wherein the information about a method of sending reception quality information for the media includes pieces of information about contents included in the reception quality information, a period in which the reception quality information is transmitted, and a network status at a point of time at which the reception quality information is transmitted.
