摘要： An apparatus for determining an encoding mode in an H.264 encoder is provided with a 16×16 macroblock number calculating unit and a threshold updating unit. The 16×16 macroblock number calculating unit calculates means of the number of 16×16 macroblocks. The threshold updating unit compares the number of 16×16 macroblocks of a frame, which is chosen to be currently encoded, with the mean of the number of 16×16 macroblocks among or within the frames, and updates a currently set threshold according to a result of comparing. Then, calculating unit checks the number of times by which the encoding mode is determined by the 16×16 macroblock in a frame whose encoding is currently completed, and the threshold updating unit compares the number of times with the currently set threshold to increase or decrease the threshold according to a result of the comparison.

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 an image encoding apparatus and a memory access method. The image encoding apparatus for encoding image data includes: a memory for storing a frame of the image data; a motion prediction unit for detecting a motion vector of a predetermined block unit for a currently-input image frame based on the stored frame, and accessing the memory in order to perform sub-pixel interpolation for a corresponding block of the motion vector; and a motion compensation unit for performing motion compensation with respect to a frame block to be compressed, by using the detected motion vector, thereby reducing the number of times the memory is accessed for encoding. Since the number of memory access times is reduced, which is very frequently used in interpolation of a color difference signal, low-power encoding is achieved.
