Abstract: Systems and methods for an online forum for video distribution are provided. A video file having a first format is received from a first client. The received video file is converted from the first format to a second format and is stored on a server, where the converted video file is accessible to a second client.

Abstract: Systems and methods for delivering media over a network are provided. Multiple media assets are stored on a server, as well as a representation for at least one media asset. The representation of a media asset is delivered to a client. A client user request based on selection of a representation is received, and the represented media asset is delivered from the server in response to the client user request.

Abstract: A media system that centrally manages and stores media contents and also controls the delivery of media content to subscribers is disclosed. According to one aspect, an administrator can control program scheduling, rates, service packages and system configuration for a media delivery system. Additionally, the administrator may also control billing, transaction monitoring, and customer relations. According to another aspect, the media delivery system provides subscribers with centrally managed storage for paused or recorded media. Still another aspect is that the media delivery system can restrict various administrators to different modules of the media delivery system.

Abstract: A method and an apparatus perform an inverse telecine procedure on a video sequence to eliminate redundant information introduced by the telecine process, so as to achieve more efficient data compression. The method and apparatus maintain synchronization between audio and video portions of the video sequence by ensuring that 20% of all frames, distributed substantially uniformly over the video sequence, are deleted. One embodiment of the present invention is provided in desktop computer system.

Abstract: A system for digital video editing and publishing is disclosed including a video capture unit, a video compression unit, and video decompression unit coupled to a host computer having video editing capabilities. This system allows video editing to occur using intraframe-only compressed video data. The edited video data can then be decompressed and recompressed to provide compressed data, which is compressed using both interframe and intraframe operations, usable for publication in a removal storage medium, such as a compact disk or a data network.

Abstract: Detection of liquid leaks and other changes in variables is disclosed. The event causes two elongate conductors to become electrically connected at a location which is determined by the event, thus creating a system in which the connection point can be located by measuring the potential drop from one end of one of the conductors (called the locating member) to the connection point. The system comprises a balancing component so that its sensitivity is not dependent on the location of the event along an elongate path. A fixed current flows through the connection, so that the result is independent of the resistance of the connection. The locating member can be a continuous resistive wire, coated with a conductive polymer; such a locating member can form part of a sensor cable in which the elongate components of the circuit are in a wrapped configuration. Alternatively the locating member comprises a plurality of discrete resistors.

Abstract: A digital video compression system and an apparatus implementing this system are disclosed. Specifically, matrices of pixels in RGB, YUV or CMYK formats are accepted for data compression. The data are rearranged in 8x8 pixel blocks, each block being of one pixel component type. The pixel data are then subjected to a discrete cosine transform (DCT). A quantization step eliminates DCT coefficients having amplitude below a set of preset thresholds. The video signal is further compressed by coding the elements of the quantized matrices in a zig-zag manner. This representation is further compressed by Huffman codes. Decompression of the signal is substantially the reverse of compression steps. The inverse discrete cosine transform (IDCT) may be implemented by the DCT circuit. The circuits may be implemented in a single integrated circuit chip. Three levels of compression rate control are provided during processing of video data.

Abstract: An elongate sensor for detecting and locating presence of a liquid, e.g. water or a hydrocarbon. The sensor includes first and second elongate members which are spaced apart from each other and each of which is a metal conductor covered by a conductive polymer; a third, insulated elongate conductor; and an elongate insulating core. At least one of the elongate members is helically wrapped around the core. Presence of the liquid at any point along the length of the sensor causes the first and second members to be electrically connected at that point, creating a system in which the potential drop down one of the members can be measured and the location of the connection determined.

Abstract: Detection of events, e.g. liquid leaks and other changes in varibles. The event causes two conductors to become electrically connected, and thus creating a system in which the connection point can be located by measuring the potential drop from one end of one of the conductors (called the locating member) to the connection point. Preferably a fixed current flows through the connection, so that the result is independent of the resistance of the connection. The locating member can be a continuous resistive wire, preferably coated with a conductive polymer; such a locating member can form part of a sensor cable in which the elongate components of the circuit are in a wrapped configuration, or part of a cable in which the conductors are separated by a member shaped to prevent capillary action of a liquid from connecting the conductors. Alternatively the locating member comprises a plurality of discrete resistors.
