Abstract: An apparatus and method to preferentially select code quantity from DPCM path in a manner to satisfy the target code quantity thereby preventing deterioration of image quality. Code quantities obtained by a first compression system of quantizing an input image signal by quantization steps different from each other, or code quantities obtained by a second compression system which has compression factor and loss which are lower than those of the first compression system are added on an encoding system selection basis to calculate a total code quantity of equi-length unit. A calculated total code quantity and a target code quantity in the equi-length unit are compared to determine quantization step in the first compression system in accordance with the comparison result to select, on the encoding system selection basis, the first compression system or the second compression system of performing quantization by the determined quantization step.

Abstract: A video adjustment system for processing video information is disclosed which includes a motion analyzer and an adjustment module. The motion analyzer determines a motion level metric of the video information based on at least one motion parameter. The adjustment adjusts an initial dynamic light scaling factor to provide an adjusted dynamic light scaling factor based on the motion level. The dynamic light scaling factor may be used for luminance compensation and backlight display scaling. The motion level may be based on any type of motion information, such as motion vector information or information indicating a scene change. A distortion module may perform a distortion evaluation of the video information for calculating the initial scaling factor. Alternatively, the distortion module may include a memory which stores predetermined scaling factors based on statistical distortion level characterization.

Abstract: When frame data is acquired to a digital camera, a block split section splits the frame data into a plurality of correlation detection blocks, an average value calculation section calculates an average pixel value of each of the correlation detection blocks, and an activity calculation section calculates a block activity value of each of the correlation detection blocks from the calculated average pixel value of each of the correlation detection blocks. Next, a group allocation section allocates the individual correlation detection blocks to two groups on the basis of the calculated block activity value, and a motion vector for each group is calculated using the representative point matching method. Next, the motion vector calculation section calculates the entire motion vector from the motion vectors for each group in accordance with the ratio between the numbers of calculation detection blocks in each group.

Abstract: There is disclosed a scalable encoding device capable of increasing the conversion performance from a narrow-band LSP to a wide-band LSP (prediction accuracy when predicting the wide-band LSP from the narrow-band LSP) and realizing a high-performance band scalable LSP encoding. The device includes a conversion coefficient calculation unit (109) for calculating a conversion coefficient by using a narrow-band quantization LSP which has been outputted from a narrow-band LSP encoding unit (103) and a wide-band quantization LSP which has been outputted from a wide-band LSP encoding unit (107). The wide-band LSP encoding unit (107) multiplies the narrow-band quantization LSP with the conversion coefficient inputted from the conversion coefficient calculation unit (109) so as to convert it into a wide-band LSP. The wide-band LSP is multiplied by a weight coefficient to calculate a prediction wide-band LSP.

Abstract: Provided is a method and system for splitting a video stream into X minute video segments and further dividing those video segments into M multiplex files. Each multiplex file can have a Time to Live (TTL). This allows for part of the video to be deleted from disk by just removing a single multiplex file. The remaining multiplex files can be combined to play back the video at a reduced sample rate.

Abstract: A method segments a video. Audio frames of the video are classified with labels. Dominant labels are assigned to successive time intervals of consecutive labels. A semantic description is constructed for sliding time windows of the successive time intervals, in which the sliding time windows overlap in time, and the semantic description for each time window is a transition matrix determined from the dominant labels of the time intervals. A marker is determined from the transition matrices, in which a frequency of occurrence of the marker is between a low frequency threshold and a high frequency threshold. Then, the video is segmented at the locations of the markers.
