    摘要: A jitter correction method of a transmitting device, a jitter correction method of a receiving device, a transmitting device, and a receiving device are provided. The jitter correction method of the transmitting device includes: determining a time stamp of a video frame; determining a transfer time of an real-time transport protocol (RTP) packet that includes at least a part of the video frame as a payload; generating the RTP packet including the time stamp and the transfer time; and transmitting the RTP packet to a receiving device.

    摘要: A method for performing an encrypted voice call between a first terminal and a second terminal supporting a Voice over Internet Protocol (VoIP)-based voice call. In the method, the first and second terminals generate and store a bio key using biographical (bio) information of a user in advance before performing a voice call, the first terminal sends a request for a voice call to the second terminal and establishing a session, the first and second terminals exchange and store a bio key stored in each terminal, and the first and second terminals generate a session shared key using the exchanged bio key and starting a Secure Real-time Transport Protocol (SRTP) session, and a restored bio key by acquiring bio information from received data. User authentication is then performed by comparing the bio key with the restored bio key.

    摘要: An audio and video synchronization apparatus and method in a wireless communication network are provided. The audio and video synchronization apparatus includes a receiver that receives audio frames and video frames, a playback buffer that sequentially buffers the audio frames, a detector that determines whether the audio frames are synchronized with the video frames and adjusts a playback time of the video frames based on a playback time of the audio frames if it is determined the audio frames are not synchronized with the video frames.
