Methods and apparatus to selectively display a pre-determined set of contents for a specific class of devices. The apparatus includes an image generator, a section identifier and a section manipulator. The image generator generates an image of a pre-determined rendition of the set of contents; the section identifier identifies a section in the contents based on a preference of the provider of the set of contents; and the section manipulator re-formats the identified section to generate a new rendition, depending on a characteristic of the specific class of devices and a preference of the provider. After the re-formatting, the new rendition is displayed on the specific class of devices.

Methods and apparatus to handle cookies in a response Web page requested by a client. One method includes the steps of (a) generating a session id to identify a new session, (b) striping off any cookies set by an external web site from the response header of the response Web page, (c) appending the session id to all of the links embedded in the response page, and (d)sending the modified response page, with the new header, to the client.

Removing cookies from web page response headers and storing the cookies in a repository for later use

A transmission method for video image data using an embedded bit stream in a hierarchical table-lookup vector quantizer comprises the steps encoding an image using hierarchical vector quantization and an embedding process to obtain an embedded bit stream for lossless transmission. The bit stream is selectively truncated and decoded to obtain a reconstructed image.

A method and an apparatus of synthesizing speech from a piece of input text . In one embodiment, the method includes the steps of retrieving the input text entered into a computing system, and transforming the input text based on the semantics of at least one word of the input text to generate a formatted text for speech synthesis. The transforming includes adding an audio rendering effect tot he input text based on the semantics of at least one work, the audio rendering effect comprising background music, special effect sounds, and context-sensitive sounds. In another embodiment, the transformation also depends on at least one characteristic of the person listening to the speech output In yet another embodiment, the transformation further depends on at least one characteristic of the hardware employed by the user to listen to the speech output The transformed text can be further modified to fit a text-to-speech engine to generate the speech output

Intelligent text-to-speech synthesis

An apparatus and a method to generate a hyperlinked abstract from a markup language document by parsing the document to create a syntax tree, analyzing statistically the syntax tree based on at least one rule, classifying information at each node of the syntax tree, adapting information at each node of the classified tree for outputting and summarizing the adapted tree to create a hyperlinked abstract of the document to be presented at an output device. The abstract can be considered as a summarized version of the document. It occupies less bandwidth than the document, allowing it to be transmitted to a user at a much faster pace, even if the user's computing system and connection are not very sophisticated. Through the abstract, the user can quickly become aware of the coverage of the document. If more detailed information is preferred, the user can access those materials in the document through hyperlinks. In one embodiment, the summarization step includes grouping, in which a pre-determined number of nodes are grouped together. In another embodiment, after summarization, the tree can be modified by an output-specific filter, and can be sent to an output device.

Method and apparatus to deliver an application to a client through a transmission medium. The application can be an interactive application, and the apparatus includes an appliance-specific transducer and an adaptive-transmission transducer. The appliance-specific transducer, in view of the client's request for the interactive application in the server, is configured to modify the application based on at least one characteristic of the client and at least one characteristic of the application to generate an appliance-specific output. Based on at least one characteristic of the application and at least one characteristic of the medium of transmission, the adaptive-transmission transducer is configured to modify the appliance-specific output to generate an adapted output. The output is delivered through the medium to the client, which includes a decoder and a user-interface. The decoder decodes the adapted output to produce a modified version of the interactive application to be used by a party through the user-interface. In another embodiment, the application can be a push application.

A transducer for transforming a set of syntactic and sampled data from a general purpose system to control a special purpose system. The transducer includes a first and a second transducer modules. The first transducer module is coupled to the general purpose system for receiving the syntactic and sampled data from the general purpose system, and to transform the received data into a different set of syntactic and sampled data. The second transducer module is coupled to the first transducer module for receiving the syntactic and sampled data generated by the first transducer module, and transforming the received data into another set of syntactic and sample data that are different from the other two sets of syntactic and sampled data to control the special purpose system.

A weighted wavelet hierarchical vector quantization (WWHVQ) procedure is initiated by obtaining an N.times.N pixel image where 8 bits per pixel (steps 10 and 12). A look-up operation is performed to obtain data representing a discrete wavelet transform (DWT) followed by a quantization of the data (step 14). Upon completion of the look-up, a data compression will have been performed. Further stages and look-up will result in further compression of the data, i.e., 4:1, 8:1, 16:1, 32:1, 64:1, . . . etc. Accordingly, a determination is made whether the compression is complete (step 16). If the compression is incomplete, further look-up is performed. If the compression is complete, however, the compressed data is transmitted (step 18). It is determined at a gateway whether further compression is required (step 19). If so, transcoding is performed (step 20). The receiver receives the compressed data (step 22). Subsequently, a second look-up operation is performed to obtain data representing an inverse discrete wavelet transform of the decompressed data (step 24). After one iteration, the data is decompressed by a factor of two. Further iterations allows for further decompression of the data. Accordingly, a determination is made whether decompression is complete (step 26). If the decompression is in incomplete, further look-ups are performed. If, however, the decompression is complete, the WWHVQ procedure is ended (step 28).
