摘要： In one embodiment, a network device analyzes an encoded stream to identify a timing value included in a packet before a splice point. Next, the device determines a difference between identified timing value and a timing value included in a packet of the encoded segment to be spliced. In conjunction with splicing, the network device formats timing values of packets according to the determined difference, which improves play out of the spliced stream.

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： 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： 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 supporting trick modes in a streaming digital video environment involves receiving a source stream of digital video content that is encoded for a normal playout rate and generating a root trick mode stream from the source stream, wherein the root trick mode stream is generated for a playout rate that is faster than the normal playout rate. The root trick mode stream is then used to generate subsequent trick mode streams that have faster playout rates than the root trick mode stream. Using a root trick mode stream to generate subsequent trick mode streams requires only one trick mode stream to be generated at ingest and therefore reduces ingest processing requirements and eliminates the need to store a different trick mode stream for every possible trick mode playout rate.

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： A method and system for conditioning a media stream for splicing are disclosed. In an embodiment, content-specific splice points, which correspond to a possible playout splice point within an original media stream, are identified for both audio and video components of the original media stream. Once the audio bitstream and video bitstream splice points are identified, the audio bitstream in the vicinity of the audio bitstream splice point is packetized into IP packets containing only audio with one of the audio-containing IP packets having an IP packet boundary that corresponds to the audio bitstream splice point and the video bitstream in the vicinity of the video bitstream splice point is packetized into IP packets containing only video with one of the video-containing IP packets having an IP packet boundary that corresponds to the video bitstream splice point. The conditioned original media stream is then transmitted downstream to a splicer.

摘要： In one embodiment an apparatus for splicing an ad into a data stream includes an ad segmenter, an ad variant generator coupled to the ad segmenter, and an ad variant selector coupled to the ad variant generator. The ad segmenter designates end portions, including beginning and ending portions, of the ad and designates an intermediate portion between the end portions. The ad variant generator generates a plurality of variants of at least one end portion. Each variant corresponds to a unique bit-rate. The ad variant selector selects at least one variant for splicing into the data stream based on a buffer level of a data stream buffer.

摘要： A network transmitter schedules packets so that packets are transmitted to a host or group of hosts so as not to overload any particular part of the network. In an embodiment, the transmitter uses packet data structures with a schedule indication for packets placed in the queue so that an independently running adaptor may know when to remove packets from the queue and transmit them. In an alternative embodiment, packets are scheduled by setting a future interrupt for transmitting a packet or group of packets. In a further embodiment, packets are placed in temporal sets where a temporal set is a group of packets that can be transmitted in succession without violating the bandwidth limitations of any network segment.
