摘要： A method and apparatus for controlling a video encoding data rate in real-time in order to minimize performance deterioration, even when a scene change has occurred in an application field having a small number of available bits due to a low bit rate and a high frame rate. The method includes: a first step of determining whether scene change has occurred in a current frame; a second step of determining whether a number of current available bits is more than a preset reference when it is determined that the scene change has occurred; and a third step of adjusting a Quantization Parameter (QP) according to a first preset condition when it is determined that the number of current available bits is more than that preset reference. An apparatus includes an encoder QP controller having a QP module for adjusting the QP.

摘要： A method and apparatus for matching compressed video data under a wireless fading environment are disclosed. The apparatus includes an encoder for encoding and outputting the video data as a compressed bit stream, a channel error measurement unit for measuring Signal-to-Noise Ratio (SNR) or Carrier-to-Noise Ratio (CNR) of a wireless channel, and an encoder optimization module for determining if the current fading is slow fading or fast fading. A control signal is output to reduce a frame transmission ratio or to change the quality of the vide data if it is determined that the current fading is slow fading. Another control signal is output to adjust the size of a data output buffer of the wireless channel if it is determined that the current fading is fast fading. The apparatus also includes a temporal Scalable Video Coding (SVC) selector 24 and an SNR SVC selector 22 for selecting the frame transmission ratio or the bit rate according to the control signal output from the encoder optimization module, to provide a frame selection signal or a bit rate selection signal to the encoder.

摘要： Disclosed is a method for extracting a region-of-interest of a user in a multimedia mobile terminal. The method includes: setting a search region in an input picture input to the multimedia mobile terminal on a screen picture-to-screen picture basis, and extracting a group of boundary of a region-of-interest based on a brightness difference between the set search region and an environment around the set search region; determining boundary coordinates of the region-of-interest through learning during a predetermined frame among the extracted group of boundary coordinate candidates; and enlarging the region-of-interest having the determined boundary coordinates, and displaying the enlarged region-of-interest. As a result, a region the user is most interested in or pays more attention to than other regions on a screen is automatically extracted. Accordingly, it is possible for users to view pictures in such an efficient manner as to provide the users with an even better experience and understanding during viewing.
