摘要： Low power event monitoring enabling logic allows wake up devices to maintain their proper functionality in the event of a momentary power loss, or in the event the operating system does not properly load upon power-up. The technology is particularly suited for use with network interface card supporting Wake-On-LAN functions. A component with low power enabling logic is provided for a system having power management resources responsive to power management event signals to switch to an operating state. The component comprises power logic having a first mode in which power consumption is limited to a first specified level and a second mode in which power consumption is limited to a second specified level higher than the first specified level. The component includes an interface to nonvolatile memory storing a control signal. Logic is coupled to the interface to the nonvolatile memory and responsive to detection of a power supply voltage to read in the first mode the control signal from the nonvolatile memory, and to the signal the power logic to enter the second mode in response to a specified state of the control signal. Monitoring resources operating in the second mode monitor for an event, and in response to detection of the event produce a signal to cause the system switch to the operating mode.

摘要： Switching a client from unicasting back to multicasting involves simultaneously providing the digital video content to the client via unicasting and multicasting until the client has buffered duplicate frames (i.e., frames that contain the same digital video content). Once the client has buffered duplicate frames, the client can transition from playing out of a buffer that holds frames received via unicasting to playing out of a buffer that holds frames received via multicasting without skipping a frame. Once the transition back to multicasting is complete, unicasting is terminated and any frames remaining in the unicast buffer are flushed.

摘要： Switching a client from unicasting back to multicasting involves accumulating enough digital video content at the client to bridge the time it takes to transition from receiving the digital video content via unicasting to receiving the digital video content via multicasting. Digital video content is accumulated at the client by temporarily increasing the stream rate of the unicast stream above the playout rate. While the digital video content is being streamed at the increased rate, the amount of digital video content stored in the client's stream buffer grows. The stream rate is held at the increased rate until the client accumulates enough frames in its buffer to be able to bridge the time it takes to transition from receiving the digital video content via unicasting to receiving the digital video content via multicasting.

摘要： A technique for managing the streaming of digital video content to multiple clients involves identifying an attribute of a content element that is streamed to a client and selecting a protection mechanism for the content element as a function of the attribute, wherein the protection mechanism enables streaming of the content element to the clients in the event of a resource failure. In an example, the identified attribute is an indication of the popularity of the content element (e.g., as measured by the number of active streams), such that the protection mechanism is selected as a function of the popularity of the content element. In an embodiment, protection mechanisms that offer a higher level of protection are selected for the more popular content elements and protection mechanisms that offer a lower level of protection are selected for the less popular content elements.

摘要： In a digital video network that is capable of distributing digital video content to a client via multicasting and unicasting, servicing a channel change request from a client involves switching from providing the digital video content to the client via multicasting to providing the digital video content to the client via unicasting and continuing to provide digital video content to the client via unicasting until a pre-established condition is met. Continuing to provide digital video content to the client via unicasting until a pre-established condition is met allows the network to opportunistically switch the client from unicasting back to multicasting.

摘要： A technique for streaming digital video content to multiple clients involves establishing a logical group of IP-connected stream servers, generating state information at multiple stream servers within the logical group, sharing the state information amongst stream servers in the logical group, and using the shared state information to respond to resource failures within the logical group. By sharing state information within the logical group of stream servers, stream servers with the shared state information can quickly take over the active streams from a failed stream server within the logical group. The quick transition of responsibility from one stream server to another enables the streaming network to provide continuous streaming of digital video content to the viewer without interruption.
