    • According to one embodiment, the present technique provides a method of transporting a cryogenic device between first and second facilities. The exemplary method includes actively maintaining cryogen in the device within desired parameters. According to another embodiment, the present technique provides a portable resource supply, which provides resources to a cryogenic imaging device during transportation. Advantageously, the portable supply unit may actively maintain cryogen in the imaging device within desired parameters. Moreover, the portable supply unit may reduce the likelihood of a loss of cryogen and a loss of superconductivity in the imaging device. Furthermore, the present technique provides a maintenance system for cryogenic imaging devices. As one example, the maintenance system may include an intermediate facility having resources for maintaining a cryogenic imaging device during transportation thereof. That is, the intermediate facility may maintain the cryogenic imaging device within desired operating parameters, such as a superconductive state, once it has left a manufacturing facility and prior to its arrival at a destination facility, such as a medical imaging center.
    • 根据一个实施例,本技术提供了一种在第一和第二设施之间运送低温装置的方法。 该示例性方法包括主动地将设备中的冷冻剂维持在期望的参数内。 根据另一实施例,本技术提供便携式资源供应,其在运输期间向低温成像装置提供资源。 有利地,便携式供应单元可以主动地将成像设备中的冷冻剂保持在期望的参数内。 此外,便携式供应单元可以降低成像装置中冷冻剂损失和超导性损失的可能性。 此外,本技术提供了一种用于低温成像装置的维护系统。 作为一个示例,维护系统可以包括具有用于在运输期间维持低温成像装置的资源的中间设备。 也就是说,中间设备可以将低温成像设备保持在期望的操作参数(例如超导状态)中,一旦其离开制造设施并且在其到达诸如医学成像中心之类的目的地设施之前。

    • Disclosed are systems and methods for creating a trick mode stream. A digital home communication terminal (DHCT) comprises a network interface, a storage medium, at least one memory storing program code; and at least one processor programmed by at least the program code. The network interface is in communication with a second DHCT. The program code enables the DHCT to: select a first encoded picture frame from a recorded video stream on the storage medium; retrieve a first sequence of transport packets encapsulating the first picture frame; create a first transport packet containing a first client control packet associated with the first picture frame; and transmit, to a video decoder in the second DHCT, a trick mode stream comprising the first transport packet followed by the first sequence of transport packets. The first client control packet comprises the size of the first picture frame and a decoder command.
    • 公开了用于创建特技模式流的系统和方法。 数字家庭通信终端(DHCT)包括网络接口,存储介质,至少一个存储程序代码的存储器; 以及至少一个处理器至少由程序代码编程。 网络接口与第二个DHCT通信。 程序代码使DHCT可以:从存储介质上记录的视频流中选择第一编码图像帧; 检索封装所述第一图像帧的第一传输分组序列; 创建包含与第一图片帧相关联的第一客户端控制分组的第一传输分组; 并且将所述第二DHCT中的视频解码器发送到包含所述第一传输分组的特技模式流,所述第一传输分组后跟所述第一传输分组序列。 第一客户端控制分组包括第一图像帧的大小和解码器命令。
