Abstract: PURPOSE: A multimedia service providing method for guaranteeing the quality of service (QoS) is provided to secure the QoS of a real time multi-media service by recognizing the change of a service device and the network specificity by the handover on wireless network environment. CONSTITUTION: The quality of media is remarkably lowered for encoding when the available bandwidth of remote device network is narrower than the predetermined standard available bandwidth (S403). A data packet transmission range to a handover occurrence point is reduced when the media receiving packet delay and the loss rate is greater than the predetermined standard range based on a received session initiation protocol (SIP) message. A data packet capable of being lost during the time for the handover is transmitted before the occurrence of the handover (S404).

Abstract: PURPOSE: A data packet transmission method is provided to improve the stability of transmission by preventing the degradation of total bandwidths. CONSTITUTION: An access point receives a unicast packet transmitted from a predetermined terminal connected to a wireless network (S401). The access point determines a data packet transmission method including rapid transmission speed between the broadcast method or the unicast method based on the number of terminals connected to a wireless network and the access point (S402). The access point transmits broadcast packet converted into the unicast packet to the access point and each terminal connected to the wireless network when the transmission speed of the broadcast method is faster than the unicast method (S403-S404). [Reference numerals] (AA) Start; (BB) Finish; (S501) Receives packets; (S502) Convert into external network address; (S503) Transmit to external interface; (S504) Broadcasting transmission is faster.; (S505) Convert into each connected terminal unicast address; (S506) Transmits to access point interface; (S507) Convert into an original broadcast address

Abstract: PURPOSE: A video call device for group media communication and a processing method thereof are provided to set different display resolution according to the number of participants in the group image communication. CONSTITUTION: An encoding unit(110) compresses the original data into the specific resolution. A plurality of decoding units(120-1~120-N) restores the compressed data by using an assigned memory. A group communication management unit(130) selectively activates at least one or more decoding units from the plurality of decoding units based on the reference information by video call mode which is differentiated by the number of participants in the video call service. The group communication management unit increases the display resolution and the size of the memory based on the reference information.

Abstract: PURPOSE: A method of fast mode decision of an enhanced layer using a rate-distortion cost in an SVC encoder, and an apparatus thereof are provided to remove an unnecessary motion mode for a current macro block of an upper layer by using motion detection information of a previous frame and the motion detection information of a lower layer. CONSTITUTION: Bit rate distortion values for a current macro block of an enhanced layer and a previous block are calculated(S100). A final bit rate distortion value for the previous macro block is calculated by compensating the bit rate distortion value for the previous macro block as the compensating value for reflecting the correlation with a previous video frames(S200). The bit rate distortion value for the current macro block is compared with the final bit rate distortion value to select a motion mode excluded from the current macro block(S300).
