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.

Audio and video synchronization apparatus and method in wireless communication network

Provided are a multimedia data reproducing method and an apparatus for controlling a multimedia data reproducing speed based on a multimedia data packet receiving speed. The method including controlling a reproducing speed of the multimedia data based on a first time difference between times at which a plurality of packets including the multimedia data are respectively received and a second time difference between times to respectively reproduce the multimedia data corresponding to the plurality of packets; and reproducing the multimedia data at the controlled reproducing speed.

Method and apparatus for reproducing multimedia data by controlling reproducing speed

Disclosed are a method of transmitting/receiving streaming data, to which a bit rate suitable for a mobile communication terminal is applied, in a communication system including a server and the mobile communication terminal, and a communication system therefor. The communication system include the server for converting multimedia data into the streaming data, and transmitting the streaming data to the mobile communication terminal; and the mobile communication terminal for, on receiving the streaming data from the server, collecting streaming parameters for use to determine the bit rate, and newly determining the bit rate.

Method of transmitting/receiving streaming data in communication system including server and mobile communication terminal, and communication system therefor

A method of performing an intra prediction coding with respect to a plurality of blocks included in an image frame is provided. The method of performing an intra prediction coding includes confirming whether a neighboring pixel that is referred to in an intra prediction of a block exists in the current frame, if the neighboring pixel referred to in the intra prediction exists, reading the color difference signal value of the pixel referred to in the intra prediction from the current image frame, if at least one neighboring pixel referred to in the intra prediction does not exist, reading the color difference signal value of at least one pixel from the previous image frame and performing the intra prediction with reference to the read color difference signal value of the pixel.
