摘要： A method is described for encoding video. A video sequence is captured at a full frame resolution. Boundaries for an inner region are identified within frames of the video sequence. The video sequence is encoded at the full frame resolution into a bitstream. The bitstream includes a sub-bitstream which encodes for the inner region. Data is embedded within the bitstream. The data identifies the sub-bitstream within the bitstream. In one aspect, the data is a header specifying the inner region. In another aspect, the encoding estimates motion for pixels within the inner region based on pixels within the inner region.

摘要： In an encoding process, video data are represented as a bitstream of a quantized base layer and one or more enhancement layers, which capture the difference between a quantized base video picture and an original unquantized input video picture. Due to bandwidth constraints on a communication channel, it may be unfeasible to transmit all enhancement layers. During the encoding process, the enhancement layer data may be adjusted to give transmission priority to information in the enhancement layers that is visually important. Following transmission, the adjustment may be undone during the decoding process.

摘要： A multimedia communication system in an Internet Protocol (IP) network includes broadcast capabilities. A system-wide emergency broadcast initiated by a user with the appropriate authority interrupts all teleconferences in progress. A group-wide high priority broadcast initiated by a user with the appropriate authority may interrupt some teleconferences in progress in the selected or other group(s). A group-wide normal priority broadcast allows all teleconferences to remain in progress and user may choose to join or not join the broadcast when the in-progress teleconference has ended.

摘要： Embodiments are directed to systems and methods for delivering broadcast television (TV) using an Internet Protocol (IP) network. The IPTV system and methods use real-time routing servers to unicast and/or multicast of broadcast television programs. The IPTV system and methods may enable advertisers to insert local commercials into national or international television broadcasts. The IPTV system and methods offer network-based time-shifting of broadcast television programming rather than personal video recorder (PVR)-based time-shifting. The IPTV system and methods may provide scalable video on-demand (VOD) by multicasting video content and dynamically determining whether to speed up or slow down a bit stream to catch up to or wait for the previous or next multicast of the video content. The IPTV system and methods also may enables interactive television programming whereby a viewer may be permitted to exchange video with a television program and have that video displayed.

摘要： A technique for encoding and decoding an image includes the following steps: subsampling the image to obtain a number of subsampled frames of spatially offset image-representative signals; transforming each of the subsampled frames to obtain a corresponding number of frames of transform coefficient-representative signals; forming vector-representative signals from corresponding coefficient-representative signals of the respective frames of coefficient-representative signals; performing a thresholding operation on the vector-representative signals to obtain thresholded vector-representative signals; vector quantizing the thresholded vector-representative signals to obtain encoded signals; storing the encoded signals; and decoding the encoded signals to obtain a recovered version of the image.

摘要： A method for decomposing signals into efficient time-frequency representations for data compression and recognition which uses adaptable wavelet basis functions and concentrates a signal or image's information to a higher degree than methods based on the discrete fourier transform, the discrete cosine transform, the standard wavelet transform and known adaptive transform techniques. The purpose of the present invention is to enable data signals and images to be stored and transmitted very efficiently. The time-frequency plane is broken up into subspaces. The method determines the optimum basis function for each of the subspace regions. Basis functions are chosen such that much of the information in the signal is contained in a small number of coefficients. The resulting coefficients form a set that represents the signal in the most concentrated manner.

摘要： The present invention relates to lighting strips and more particularly to modular lighting systems comprising lighting devices, for example, lighting strips, physically and electrically connectable with one another by way of a plug and socket integrally formed at opposing ends of the lighting strips. The lighting strip devices can be made of flexible material to allow for applying the lighting devices along flat as well as contoured surfaces. The lighting strips can also be rigid. More particularly, embodiments of the invention include modular lighting strips comprising: a non-conductive substrate strip comprising an electrical circuit; a plurality of light sources operably connected to the electrical circuit; a plug integrally formed at an end of the substrate strip; and a socket integrally formed at an opposing end of the substrate strip; wherein the plug and socket provide for removable, friction-fit, latch or latchless, and electrical interconnection of two or more circuits. Also included in the invention are connector assemblies comprising the inventive socket and plugs integral to PCBs for use in the field of electronics. One or more lighting strip can be combined to form lighting systems, which are useful in many functional and decorative lighting applications. The lighting systems are useful for any residential or commercial application where modular, discrete, low-profile, and/or flexible lighting is desired. The lighting strips of the invention can be used in particular for back lighting, accent lighting, aisle or path lighting, contour lighting, elegant interior decoration, holiday decorations, or landscape lighting.

摘要： A medical device and method for transportation and release of a therapeutic agent into a mammalian body are disclosed. The medical device is coated with alternating layers of a negatively charged therapeutic agent and a cationic polyelectrolyte, following a controlled adsorption technique. The method is simple, with minimal perturbation to the therapeutic agent and uses clinically acceptable biopolymers such as human serum albumin. The amount of the therapeutic agent that can be delivered by this technique is optimized by the number of the layers of the therapeutic agent adsorbed on the surface of medical device. There is a washing step between alternate layers of the therapeutic agent and cationic polyelectrolyte carrier, so that the amount of the therapeutic agent on the insertable medical device represents the portion that is stably entrapped and adsorbed on to the medical device. The insertable medical device and method according to this invention are capable of reproducibly delivering therapeutic agent to a site in a mammalian body, and allow for a highly reproducible and controllable release kinetics of the therapeutic agent.
