The language can include at least one conditional statement and a significance indicator. The conditional statement can define a sense of usage for a lexeme. The significance indicator can define a criteria for selecting an associated sense of usage. The language can also include an action expression that is associated with a conditional statement that defines a set of programmatic actions to be executed upon a selection of the associated usage sense. The conditional statement can include a context range specification that defines a scope of an input string for examination when evaluating the conditional statement. Further, the conditional statement can include a directive that represents a defined condition of the lexeme or the text surrounding the lexeme.

Disambiguating text that is to be converted to speech using configurable lexeme based rules

The present invention discloses a method for training an exception-limited phonetic decision tree. An initial subset of data can be selected and used for creating an initial phonetic decision tree. Additional terms can then be incorporated into the subset. The enlarged subset can be used to evaluate the phonetic decision tree with the results being categorized as either correctly or incorrectly phonetized. An exception-limited phonetic tree can be generated from the set of correctly phonetized terms. If the termination conditions for the method have been determined to be unsatisfactorily met, then steps of the method can be repeated.

A logical device that is coupled to a computer can be controlled using string commands. The logical device requires flags and a data structure to operate properly. A string command with tokens for operating a specific logical device is provided. A linked list of the tokens is created. A command table for the specified logical device is found. The command table contains possible commands for the logical device, which commands are able to provide the required flags and data structure for the logical device. Each command in the command table contains key words or tokens or multiword tokens. The command table tokens are parsed, one at a time, against the command string tokens. If no match between the command table token and a command string token occurs, then the next command table token is parsed against the command string tokens. If a match between a command table token and a command string token occurs, then the flag that is associated with the command string token is provided and data from either the command string token or the command table token is inserted into the data structure in its proper place.

A method of and apparatus for performing blitter operations is performed in two parts. First, a description of the to-be-performed data transfer is analyzed and a computer instruction sequence is generated therefrom. The instruction sequence may include the appropriate instructions to implement scaling, clipping, and color conversion of a source image, as implicated by the blitter description. Second, the computer instruction sequence is executed an appropriate number of times, again depending upon the blitter description. One of the described embodiments transforms a blitter description that describes a target image in terms of visible rectangles into a description that describes the target image as having at least one line-type, in which the line-type comprises at least one pixel run, characterized by visible and non-visible states. The line-type description is then utilized by a code-generating logic to generate the appropriate instructions. The apparatus for performing the blitter operations may be implemented as an interface library, thus allowing client programs, including interactive games, to use the advantages of the invention to perform rapid screen updates.

A technique for initiating communications from a web browser to a destination on either a packet-switched data network or a circuit-switched communication network includes a communication utility capable of interacting with a browser utility and responsive to address information obtained from a website for establishing a communication link with the website with the other destination defined by the address information. In one embodiment, the address information may comprise either an Internet protocol address, an E-mail address, or a traditional telephone number. The communication utility further enables sharing of URL data so that once a communication link is established, the parties may examine the same website pages simultaneously while communicating over a point-to-point communication link.

A digitized image compression system employs several different compression techniques to compress the luminance and chrominance information and encodes the selected technique &ldquo;on the fly&rdquo; by inserting selected escape and header codes into the encoded data stream. More particularly, during compression, each image is divided into non-overlapping contiguous regions, referred to hereinafter as blocks and image data is compressed on a block-by-block basis. Each encoded block begins with a one-byte header that indicates, in conjunction with a previous escape code, the compression technique which was used to encode the block. Therefore, interpretation of the encoded data is a hierarchical process: the escape codes indicate a stream interpretation mode which, in turn, determine the meaning of header values which follow and the header values, in turn, determine the meaning of the encoded data in each block. The majority of image blocks are divided into quadrants and each block header is arranged as a sequence of four two-bit codes which indicate the encoding used for the four quadrants within the associated block. However, certain combinations of encoding that are unlikely to occur within the same block are inserted into the image data stream as the &ldquo;escape codes&rdquo; which designate the stream interpretation mode.

Pixel-mode frame buffer interpretation is used to concurrently display graphical and image data in a common resolution. Pixel data in a frame buffer can be of varying types. A mask is stored in video memory and defines the 'state' of each pixel. The pixel state determines how a video controller is to interpret the pixel data for that pixel and thus allows the concurrent display of graphics data and image data.

An digital video image processing system employs codes of various lengths to encode the luminance information within the digital video images. The inventive method and apparatus divides a video image into non-overlapping regions containing a plurality of pixels with luminance values. Within each region, the method computes the total luminance variation across the region, the direction of greatest luminance change within the region, the base, or lowest, luminance value within the region and the location and type of luminance transition within the region. Depending on the variation of the luminance values within a region and on the quality desired in the decoded image, the computed information is used to encode the luminance values in short, medium, or long codes. The luminance codes may be predetermined and unchanging or they may vary from image to image or within given images.

An image-compression/decompression system employs a variable spatial-frequency encoder to encode the chrominance information contained within a video image. The system divides the video image into non-overlapping regions and partitions each region into sub-regions. Within each region, the system computes a weighted average of the chrominance values in each sub-region, and compares the weighted average value associated with each sub-region to the weighted average values associated with the other sub-regions within the region. If differences between the average values are less than a predetermined threshold amount, the system assigns a single chrominance encoded value to the entire region. If, on the other hand, the differences between the weighted average values is more than the predetermined threshold amount, the system assigns individual chrominance values to each of the sub-regions.

Multimedia data objects in memory need not be processed serially from beginning to end but may instead be defined as algorithmically generated data streams. This functionality is provided through an architected application programming interface with a mechanism for defining a method of composing a complex object from smaller objects, for defining a behavior for the complex object, and for allowing that behavior to be varied based on external events.

Hybrid compression processes for digital color video data that enables software only playback of the compressed digital video in low-end computers, wherein intraframe and interframe compression techniques are brought together through a sequence of procedures that analyze local frame regions, integrate unique processes with block truncation coding compression, and adopt the advantages of visual pattern image coding for color video. The process determines the appropriate encoding of each local frame region with one of various compression techniques, based upon its image properties. The compression methods retain the fidelity of the original video data to provide high quality video during decompression and reconstruction of high motion and textured video clips, while simultaneously providing sufficient compression and ease of decoding for software-only decompression thereby exhibiting properties that enable good quality video to be displayed in low-end computers.

Hybrid video compression system and method capable of software-only

A system and method of compressing original video data expressed in a plurality of digitally coded frames which enable decompression and playback of resulting compressed video data at one of a plurality of frame rates while maintaining temporal fidelity of the frames displayed. Compression includes selecting a plurality of rate streams for the compressed video data, including a highest rate stream including all of the frames of the original video data and a lowest rate stream including a subset of regularly spaced frames of the original video data. Then the initial frame in the original video data is spatially compressed and the resulting compressed data placed in the compressed video data. The initial frame is also saved as a base frame for all rate streams for subsequent temporal compression of the original video data. As frames are retrieved from the original video data in sequence, temporal compression based on frame differencing techniques between the retrieved frame and the base is carried out, with difference frames being stored to the compressed video data. Each difference frame is placed in the resulting compressed video data for later decompression and reproduction.
