  • Patent number: 7830409
    Abstract: 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.

    Abstract: The heat dissipating lighting system includes a closed-loop coolant path with a warmed fluid channel and a cooled fluid channel. The outlet of the warmed fluid channel is in fluid communication with the inlet of the cooled fluid channel and vice versa. Substantial portions of the warmed and cooled fluid channels are thermally isolated from one another. A light source is thermally connected to the coolant path along the warmed fluid channel, near the warmed fluid inlet.

  • Patent number: 7372904
    Abstract: 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.

  • Publication number: 20080037576
    Abstract: 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.

  • Patent number: 7232805
    Abstract: The present invention provides a cobalamin-drug conjugate suitable for the treatment of tumor related diseases. Cobalamin is indirectly covalently bound to an anti-tumor drug via a cleavable linker and one or more optional spacers. Cobalamin is covalently bound to a first spacer or the cleavable linker via the 5?-OH of the cobalamin ribose ring. The drug is bound to a second spacer of the cleavable linker via an existing or added functional group on the drug. After administration, the conjugate forms a complex with transcobalamin (any of its isoforms). The complex then binds to a receptor on a cell membrane and is taken up into the cell. Once in the cell, an intracellular enzyme cleaves the conjugate thereby releasing the drug. Depending upon the structure of the conjugate, a particular class or type of intracellular enzyme affects the cleavage. Due to the high demand for cobalamin in growing cells, tumor cells typically take up a higher percentage of the conjugate than do normal non-growing cells.

  • Publication number: 20070130601
    Abstract: 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.
