摘要： A nine-square virtual input system includes a nine-square virtual keyboard having multiple subsidiary nine-square grids. There is a main-location subsidiary nine-square grid, and each subsidiary nine-square grid has virtual keys corresponding to predefined symbols or user options respectively. A display device displays the virtual keyboard. A remote control controls the display device and has an input function key, a set of direction keys, and a set of digit keys. By pressing the input function key, the display displays the virtual keyboard in an OSD manner. By pressing the set of direction keys, an input focus is moved among the subsidiary nine-square grids, and then by pressing the set of digit keys to select a virtual key, the predefined symbol or user option corresponding to the selected virtual key is inputted.

摘要： To encode an unencoded block of a frame, a search window is defined within the frame. Each pixel disposed within the search window and disposed in the unencoded portion of the frame that is assigned a value. A difference is computed between the unencoded block and each possible block within the search window. The block having the smallest difference, together with this difference are used to encode the unencoded block.

摘要： To detect color motion artifacts in a video frame, a motion-compensated color-distance value is compared against a threshold value. If the motion-compensated color-distance value is greater than or equal to the threshold value, color-motion artifacts are detected. The motion-compensated color-distance value is a sum of absolute values of the differences between corresponding pixel values of the video frame and a reference frame. To detect color motion artifacts in a video frame, in another embodiment, luminance and chrominance components of the intra-frame activity levels are compared against luminance and chrominance components of the inter-frame activity levels. If any of the components of the inter-frame activity levels is greater than the corresponding components of the intra-frame activity levels, color-motion artifacts are detected. To reduce color-motion artifacts, either a smaller quantization scale or intra-frame encoding is used to encode the data.

摘要： A portion of the number of bits initially allocated for encoding some of the frames of a group of pictures (GOP) is accumulated in a bit bank and is subsequently used to encode other frames that may require a larger number of bits to encode than those initially allocated for these frames. Furthermore, when a scene change P frame is detected in a first GOP, a second GOP is formed. The second GOP includes the scene change P frame as well as the remaining unencoded frames of the original GOP. The P frame of the first GOP is changed to an I frame in the second GOP. Furthermore, the frame to be displayed after the I frame of the second GOP is also changed to a duplicate of the I frame of the second GOP.
摘要翻译：最初分配用于编码一组图像（GOP）的一些帧的比特数的一部分被积累在比特组中，并且随后被用于编码可能需要比最初编码的比特数更多的比特的其他帧分配给这些帧。此外，当在第一GOP中检测到场景改变P帧时，形成第二GOP。第二GOP包括场景改变P帧以及原始GOP的剩余未编码帧。第一GOP中的P帧在第二GOP中改变为I帧。此外，在第二GOP的I帧之后要显示的帧也被改变为第二GOP的I帧的副本。
