Abstract: In a media production system, two-dimensional images captured from physical objects are analyzed to create three-dimensional representations of the physical objects within a virtual stage. The physical objects are manipulated as abstract representations in the unified virtual stage. Representations of physical and synthetic objects are choreographed in the virtual stage within an integrated system which can also generate a media product in the form of a two-dimensional image stream of the physical and synthetic objects with optional synchronized audio tracks. To facilitate choreography, a composite display of the three-dimensional virtual stage and a two-dimensional preview are provided. Also provided are a display showing temporal representations of elements within the scene and an object catalog of object oriented representations of elements within the scene.

Title: Shaped fixed codebook search for celp speech coding
Inventor: ERZIN ENGIN
IPC: G10L19/12
Filed: 2000-04-19
Abstract: A fixed codebook response is able to better characterize an input signal of a vocoder because the entries of the fixed codebook are tailored to the input signal being processed. A uniformly distributed random noise signal is stored in a transmitting vocoder. During encoding by the transmitting vocoder, the noise signal is shaped by a weighing filter and a pitch sharpening filter, which are condition controlled by the linear predictive coding, pitch and pitch gain characteristics of the input signal being encoded. The shaped noise signal is passed though a thresholding filter to arrive at a pulse sequence having a given sparcity. The fixed codebook response is chosen as that portion of the pulse sequence which best matches a residual signal of the input signal. The indexed location of that portion along the pulse sequence is designated as the fixed codebook bits which are included within the bit frame. The identical random noise signal is stored in a receiving vocoder.  The linear predictive coding, pitch, and pitch gain characteristics are part of the bit frame, and are again used to produce an identical pulse sequence. The fixed codebook bits of the bit frame are used to index the pulse sequence to the best matching portion, and hence the fixed codebook response for the bit frame.

Abstract: Methods and apparatus for blending colors in the presence of transparency. The method includes blending a lower and an upper graphic element in accordance with a transfer mode by calculating a transfer color from a lower element color and an upper element color according to the transfer mode without regard either to a lower element alpha or to an upper element alpha; calculating a resulting alpha from the lower element alpha and the upper element alpha without regard to any of the lower element color, the upper element color, or the transfer mode; and calculating a resulting color as a weighted average of the lower element color, the transfer color, and the upper element color. The transfer mode can be an arbitrary transfer mode and can be user defined. The resulting graphic element <C,c> having color value C and alpha value c can be calculated in accordance with <C,c> = XFade ( <A,a>, XFade ( <B,1>, <T(A,B), 1>, a ), b ), where XFade (<X,x>, <Y,y>, z) - <R,r> is an operation defined by the formulas r = InterpolateAlpha (x, y, z), t = y x z / r, and R = InterpolateColor (X, Y, t) and where the lower element is <A,a> and the upper element is <B,b>. Each of the colors A, B, and C can be defined by a value for each of a plurality of colorants. The calculated values can defined by c = a + b - axb, and C = Ax (1 - (b / c)) + Bx (1- a) x (b / c) + T (A, B) xax (b / c).
