Abstract: An entropy decoder is configured to, for horizontal and vertical components of motion vector differences, derive a truncated unary code from the data stream using context-adaptive binary entropy decoding with exactly one context per bin position of the truncated unary code, which is common for horizontal and vertical components of the motion vector differences, and an Exp-Golomb code using a constant equi-probability bypass mode to obtain the binarizations of the motion vector differences. A desymbolizer is configured to debinarize the binarizations of the motion vector difference syntax elements to obtain integer values of the horizontal and vertical components of the motion vector differences. A reconstructor is configured to reconstruct a video based on the integer values of the horizontal and vertical components of the motion vector differences.

Abstract: A method of dictionary coding using coding unit (CU) based processing or using string length coding by taking into account of color component aligned matched sample-strings are disclosed. In the dictionary coding using CU based processing, the pixels in each CU is converted to one-dimensional (1-D) pixel data according to an intra-block scanning pattern. A string search is then performed to determine a match condition regarding whether a current sample-string starting at a current position of the current 1-D packed pixel data matches a previously coded sample-string in the reference 1-D packed pixel data. For string length coding by taking into account of color component aligned matched sample-strings, a flag is signaled to indicate whether the string length of one previously coded sample-string is in a length group corresponding to color-component-aligned previously coded sample-strings.

Abstract: An apparatus and method for generating a depth image are provided. The apparatus includes an optical modulator, an optical sensor, and a depth image processor. The optical modulator optically modulates light which is reflected from an object to which light modulated using a first pseudorandom (PN) sequence is irradiated. The optical modulator optically modulates the reflected light using second PN-sequences, where each of the second PN-sequences has a same PN sequence as the first PN-sequence, but the second PN-sequences have N different time shifts. The optical sensor senses the optically modulated reflective light. The depth image processor samples N intensity images from the optically modulated reflective light sensed by the optical sensor and generates a depth image of the object using the sampled N intensity images.

Abstract: A method for encoding an intra prediction mode according to the present invention selects an intra prediction mode for a current block, determines the number of valid MPM candidates by checking the validity of MPM candidates of the current block, and if the number of valid MPM candidates is less than a previously set number, adds additional intra prediction modes as MPM candidates. MPM candidates can be adaptively added on the basis of the directionality of valid MPM candidates. Additionally, during the encoding of residual intra prediction modes, residual intra prediction modes are realigned on the basis of the directionality of valid MPM candidates. Accordingly, the present invention minimizes the information for encoding the intra prediction mode of the current block by adding MPM candidates or realigning the residual intra prediction modes on the basis of the directionality of valid MPM candidates.

Abstract: A method of storing multi angle data. Data for a plurality of angles of a scene are stored in interleaved blocks. Sizes of the interleaved blocks are integral multiples of sizes of integral numbered aligned units that include packets. Angle change points are included in each of the interleaved blocks, allowing a reproducing apparatus to seamlessly jump from one angle to another angle during reproduction of the multi angle data. A number of the angle points recorded on the information storage medium is computed so that a jumping distance required by the data during reproduction does not exceed a maximum jumping distance of a reproducing apparatus.

Abstract: A method and apparatus for eliminating picture artifacts in a video media system is provided wherein a video recorder, responsive to a trick mode command, iteratively transmits one or more frames in a video signal recorded under an interlaced scanning format for display on a display device. The video signal can include a predetermined number of replicate frames associated with the frames. Moreover, structure can be provided for selectively altering the video signal to indicate the video signal was recorded under a progressive scanning format thereby causing one or more pairs of the interlaced fields associated with the frames in the recorded video signal to be simultaneously displayed on the display device. Displaying interlaced fields simultaneously during trick mode playback eliminates an artifact known as the vibration effect. In one embodiment, the structure can alter the video signal by setting the value of one or more flags in the video signal.

Abstract: A reproducing apparatus has three reproducing modes that are a first mode, a second mode, and a third mode. In the first mode, when a program that has been reproduction restricted is tried to be reproduced, the reproducing operation is paused and the user is asked whether he or she wants to reproduce the program. Corresponding to the user's reply, the reproducing operation is performed or prohibited. In the second mode, a program that has been reproduction restricted is prohibited from being reproduced. In the third mode, a program that has been reproduction restricted is unconditionally reproduced. When the power of the apparatus is turned on at step S31, a prompt that causes the user to select one of the first mode, the second mode, and the third mode is displayed. At step S33, a process for designating a mode is performed. Information of the designated mode is stored in a nonvolatile memory.
