Abstract: A method and system for forwarding information such as data files to a recipient across disparate or incompatible communication networks, which are not constrained by incompatible user devices. The sender sends information such as a data file to an intended recipient via a messaging server. The messaging server communicates with the intended recipient using basic communication tools that are generally compatible regardless of the network that the recipient is subscribed to. The messaging server stores the information, creates and sends a notification message to the intended recipient that she has information to be retrieved. The notification message includes a unique access address associated with the message, at which the recipient can retrieve the information. Different unique access addresses are associated with different messages.

Abstract: A cost effective method for generating and delivering personalized multimedia content targeted at specific end users or groups of end users via client computers coupled to local servers by a diverse computer network which includes local area networks (LANS) and/or wide area networks (WANs) such as the internet. In one embodiment, a global server provides global content via a computer network to a local server. The local server retrieves personal profile associated with the targeted end user(s) from a local database. Personalized content is generated based on the personal profile. Customized information which includes both the global and personalized content is then delivered to the targeted end user(s) via client computer(s) coupled to the computer network. Global and personalized content may or may not be related. For example, global content may be an action movie while unrelated personalized content may be an advertisement for a custom suit in the Color, style and size likely to please the targeted end user. Exemplary personal profile include indicators such as family income, hobbies and ages which provide useful indicators of the consumption habits of the end users. Such an arrangement is advantageous because the personalized content is targeted at end user(s) who have a higher probability of interest in the personalized content based on the personal profile.

In one embodiment, a global server provides global content via a computer network to a local server. The local server retrieves local content from a local database. Customized information which includes both the global and local content is then delivered to a group of end users via client computers coupled to the computer network. Global and local content may or may not be related. An example of related global/local content is an action movie and an accompanying local language subtitle.

Abstract: A cost effective method for generating and delivering scalable multimedia content targeted at specific end user(s) via client computers coupled to servers by a diverse computer network which includes local area networks (LANs) and/or wide area networks (WANs) such as the internet. In one embodiment in which the server is billed for network bandwidth consumed, upon receiving an end user request for multimedia content, the server computes the likelihood of patronage. Indicators useful for estimating the likelihood of patronage include regularity of patronage, income history, credit worthiness, age, hobbies, occupation and marital status. A cost effective bandwidth is selected for delivering the requested content. Such an arrangement is advantageous because the content is delivered to end user at a bandwidth corresponding to the probability of consummating a sale.

Abstract: A software-based encoder is provided for an end-to-end scalable video delivery system that operates over heterogeneous networks. The encoder utilizes a scalable video compression algorithm based on a Laplacian pyramid decomposition to generate an embedded information stream. The decoder decimates a highest resolution original image, e.g., 640.times.480 pixels, to produce an intermediate 320.times.240 pixel image that is decimated to produce an intermediate 160.times.120 pixel image that is compressed to form an encodable base layer 160.times.120 pixel image. This base layer image is decompressed to form an image that is up-sampled by interpolation to produce an up-sampled 320.times.240 pixel image. This up-sampled image is subtracted from the intermediate 320.times.240 pixel image to form an error image that is compressed and encoded as a first enhancement 640.times.480 pixel layer. The decompressed base layer image is also up-sampled at step to produce an up-sampled 640.times.480 pixel image that is subtracted from the original 640.times.480 pixel image 200 to yield an error image that is compressed to yield a second enhancement 320.times.240 pixel layer. Collectively, the base and enhancement layers comprise the transmitted embedded bit stream. At the receiving end, the decoder extracts from the embedded stream different streams at different spatial and temporal resolutions. Because decoding requires only additions and look-ups from a small stored table, decoding occurs in real-time.

Abstract: A decoder is used in an end-to-end scalable video delivery system operable over heterogeneous networks. The decoder may software-based and computationally low complexity, or may be implemented inexpensively in ROM hardware. The system utilizes a scalable video compression algorithm based on a Laplacian pyramid decomposition to generate an embedded information stream. At the receiving end, the decoder extracts from the embedded stream different streams at different spatial and temporal resolutions. Decoding a 160.times.120 pixel image involves only decompressing a base layer 160.times.120 pixel image. Decoding a 320.times.240 pixel image involves decompressing and up-sampling (e.g., interpolating) the base layer to yield a 320.times.240 pixel image to which is added error data in a first enhancement layer following its decompression. To obtain a 640.times.480 pixel image, the decoder up-samples the up-sampled 320.times.240 pixel image, to which is added error data in a second enhancement layer, following its decompression. Because decoding requires only additions and look-ups from a table stored in a small (12 Kb) memory, decoding occurs in real-time. Subjective quality of the compressed images preferably is enhanced using perceptual distortion measures. The system also provides joint-source channel coding capability on heterogenous networks. The look-up table or codebook includes the inverse perceptual weighting (preprocessed) and the inverse transform (preprocessed). Decoding permits the codewords within the look-up table codebook to include preprocessed color conversion, dithering, color palletization, edge-enhancement, decimation, and interpolation.
