摘要： Strategies are set forth for performing a scaling operation on image information using a filter. According to one exemplary implementation, the strategies involve: computing, based on scaling to be performed, a number of filter kernels required to implement the filter and a number of taps required for each filter kernel; pre-computing and storing the number of filter kernels; and applying the filter kernels to a row or column of the image information by repeatedly sequencing through the filter kernels if there are more pixel elements in the row or column than there are pre-calculated filter kernels. The scaling operation can employ a Catmull-Rom filter. Further, the scaling operations can be implemented by a pixel shader by assigning weighting information and delta-shifted versions of the image information to respective texture units of the pixel shader.

摘要： Strategies are set forth herein for quantizing and dithering original image information to produce quantized image information. According to one exemplary implementation, the strategies involve: quantizing a sum that combines an original value taken from the original image information, a noise value, and an error term, to produce a quantized value; and calculating an error term for a subsequent quantizing operation by computing a difference between the quantized value and the original value. By virtue of his process, the strategies essentially add noise information to the quantization process, not the original image information, which results in quantized image information having reduced artifacts. The strategies can be used in conjunction with the Floyd-Steinberg error dispersion algorithm. According to another feature, the noise value is computed using a random number generator having a long repeat period, which further reduces artifacts.

摘要： Various described embodiments provide for per-pixel functionality in connection with pixel data that is processed by a video card for rendering on a display monitor. That is, pixel data that is associated with individual pixels that are to be rendered on a display monitor are imparted with a characteristic that enables various functionalities to be implemented at the pixel level. In one embodiment, per-pixel functionality is provided by including, in the pixel data itself, a specification of an auxiliary function that is to be performed on the pixel data associated with the individual pixels. For example, the security of the pixel data associated with each pixel can be enhanced by providing the ability to encrypt and decrypt the pixel data for individual pixels. A specification of a key that can be used for decrypting the pixel data can then be included in the pixel data itself such that when the pixel data is processed for rendering, a suitably configured decryptor can access the key specification and decrypt the pixel data.

摘要： Methods and systems are provided for synchronizing various time-stamped data streams. The data streams can be synchronized to another data stream or to a point of reference such as a reference clock. In one embodiment, synchronization processing takes place in association with a filter graph comprising multiple filters. The filter graph is configured to process multiple timestamped data streams for rendering the data streams in accordance with data stream timestamps. A synchronization module is provided and is associated with the filter graph queries individual filters of the filter graph to ascertain input timestamp-to-output timestamp mappings. The module computes adjustments that are to be made to output time stamps in order to synchronize the data streams, and then instructs queried filters to adjust their output timestamps in accordance with its adjustment computations.

摘要： Strategies are described for processing image information using a data structure which conveys color information. The color information describes color-related formatting applied to the image information. The data structure can be passed down a video processing pipeline, where each functional component in the pipeline can draw color information from the data structure to improve the accuracy of its processing. Further, each component can supply previously unknown color information to the data structure for use by other (downstream) components in the pipeline. Exemplary fields of the data structure can include one or more of: a video transfer function field; a color primaries field; an image light field; a transfer matrix field; a nominal range field; and a video chroma sampling field. The transfer matrix field can be used to convert image information from one color space to another, such as a luma-related color space to an RGB-related color space. Processing operations can be performed on progressive and linear RGB image information.

摘要： A home entertainment network transmits audio/video decrypted from a DVD over a network to a media receiver using a secure channel. The A/V data is re-encrypted in a second encryption format amenable to transmission over the network. The media stream is thereby compliant with copy protection and digital rights management requirements. The media server constructs an emulated user interface corresponding to an actual instantiation of a navigation menu on the media server to solicit user input at the media receiver. The media server alternatively constructs a unique identifier of the DVD based upon the file structure on the DVD to search for menu navigation commands over an external network for heuristic navigation control.
