    摘要： Atomic channel change in a switched digital video (SDV) system. A set-top box (STB) sends join and leave message commands to a SDV device when requesting a channel change. If one of the IGMP message commands does not reach the SDV device, oversubscription can occur. A combined join and leave message ensures that a join command is performed only when a leave command is also performed. If the single message does not reach the SDV device, the STB resends the command.

    摘要翻译： 交换数字视频（SDV）系统中的原子信道变化。 当请求频道更改时，机顶盒（STB）向SDV设备发送加入和离开消息命令。 如果其中一条IGMP消息命令未到达SDV设备，则可能会出现超额认购。 组合的加入和离开消息确保只有在执行leave命令时才执行join命令。 如果单个消息没有到达SDV设备，则STB重新发送该命令。

    摘要： The present invention is directed to a videophone system implemented over a cable television network. The instant invention provides a videophone comprising a camera for capturing images associated with a videophone signal, a videophone unit and a set top terminal or cable modem connecting the videophone to a cable television network. Videophone signals created at the call origination site are encoded and transported to a predetermined destination over an existing cable television network. The system uses IP addresses as phone number on the network. Additionally, transport of videophone signals between different cable systems is accomplished via a high-speed long distance data network, such as, for example, a satellite network, that provides communication between the headends of the different cable television systems. The set top terminal may be a conventional subscriber terminal, a cable modem or a subscriber terminal configured to operate as a cable modem. The set top terminal provides the interface between the videophone and the cable television system. More than one videophone may be connected to a single set top terminal. Display of videophone data may be achieved using any conventional display device, including a television set or a personal computer monitor. Accordingly, the videophone system described herein takes advantage of increased bandwidth and lower cost realized by using existing cable television infrastructure and technology.

    摘要： Systems and methods are disclosed for providing reverse signals from a plurality of DHCTs to a downstream modulator that is located in the headend facility. The present invention includes a single wire return device (SWRD) that receives RF modulated signals, dynamically determines the address of the associated modulator, and converts the signals into Ethernet signals. The Ethernet signals are subsequently provided to the headend facility via fiber cable.

    摘要： A luer cleaner (100) including a generally hollow body (112) having an open first end (104), a closed second end (106), and a longitudinal axis extending therethrough between the first end and the second end. The first end (104) is sized to receive therein a luer connector (190) proximal end and includes a plurality of bristles (134) extending generally toward the longitudinal axis sufficiently to engage the outer surfaces of the luer proximal end disposed therein. The second end comprises a compressible reservoir (166) containing a fluid (168), wherein, when the second end is compressed, the fluid is transmitted from the reservoir toward the first end through passageways to wet the luer proximal end. A method for cleaning luer connectors is also disclosed.

    摘要： Systems and methods are disclosed for providing downstream signals to a plurality of receiver networks. A receiver network (i.e., a networked multimedia system) includes a splitter/isolation module (SIM), a primary set-top terminal (STT), and at least one point of deployment module. The point of deployment module communicates with the primary STT via the SIM over coaxial cable. Accordingly, the point of deployment module and connected television utilize some or all of the features including hardware and software that are included in the primary STT via the networked multimedia system.

    摘要： Optimizing data rates for video services on a broadband network. Different data rates can be delivered to a subscriber premises depending on the size of the display screen connected to a set-top box, the type of content being requested, or whether there is real-time viewing. Therefore, the data rate can be optimized to maximize the number of video streams that can be delivered to any one subscriber without causing a perceived reduction in video picture quality.
