Abstract: The present invention provides methods for determining block averages in film grain simulation including determining block averages during a display process and determining block averages during a decoding process. The methods of the present invention exhibit different characteristics in terms of memory requirements and computational cost. More specifically, the first method uses no external memory, but requires either extra reads of the blocks, or internal memory in the display pipeline, while the second method requires extra memory bandwidth and extra external memory (e.g., RAM).

Abstract: A method, apparatus and system of the present invention enable the location of subtitles for a stereoscopic image and a selection of the disparity of stereo subtitles to ensure proper display of the subtitles within frames of the stereoscopic content. In one embodiment, the functionality of the concepts of the present invention is based on a player capable of displaying stereo content by reading two streams (one for the left view, one for the right view) and mixing the streams in real time using a mode supported on a 3D display (i.e. line interleaved, checkerboard pattern) based on received file information and inserting the subtitle in the frames by rendering the values in the received file information.

Abstract: Automatic determination of the complexity associated with converting image content from 2-dimensions to 3-dimensions commences by first determining how many different scenes exist within the image content. Each scene then undergoes analysis to determine its complexity based on the motion, texture and occlusion within the scene. The scene complexities are added to the scene transition complexity and the total gets weighted to yield an overall indication of the complexity of converting of image content from 2-dimensions to 3-dimensions.
Abstract translation: 通过首先确定图像内容中存在多少不同场景，自动确定将图像内容从二维转换为三维的相关开始。 然后每个场景进行分析以根据场景内的运动，纹理和遮挡来确定其复杂性。 场景复杂性被添加到场景转换复杂性，并且总体被加权以产生将图像内容从二维转换为三维的复杂性的总体指示。

Abstract: Film grain simulation within a receiver occurs by first obtaining at least one block of pre-computed transformed coefficients. The block of pre-computed transformed coefficients undergoes filtering responsive to a frequency range that characterizes a desired pattern of the film grain. In practice, the frequency range lies within a set of cut frequencies fHL, fVL, fHH and fVH of a filter in two dimensions that characterizes a desired film grain pattern. Thereafter, the filtered set of coefficients undergoes an inverse transform to yield the film grain pattern.
Abstract translation: 通过首先获得至少一个预先计算的变换系数块，发生接收器内的胶片颗粒模拟。 预先计算的变换系数的块根据表征胶片颗粒的期望图案的频率范围进行滤波。 在实践中，频率范围在二维的滤波器的切割频率fHL，fVL，fHH和fVH的集合中，其表征期望的胶片颗粒图案。 此后，经滤波的系数组经过逆变换以产生胶片颗粒图案。
