Method and system for providing site independent real-time multimedia transport over packet-switched networks

Embodiments of the invention enable minimum latency site independent real-time video transport over packet switched networks. Some examples of real-time video transport are video conferencing and real-time or live video streaming. In one embodiment of the invention, a network node transmits live or real-tine audio and video signals, encapsulated as Internet Protocol (IP) data packets, to one or more nodes on the Internet or other IP network. One embodiment of the invention enables a user to move to different nodes or move nodes to different locations thereby providing site independence. Site independence is achieved by measuring and accounting for the jitter and delay between a transmitter and receiver based on the particular path between the transmitter and receiver independent of site location. The transmitter inserts timestamps and sequence numbers into packets and then transmits them. A receiver uses these timestamps to recover the transmitter's clock. The receiver stores the packets in a buffer that orders them by sequence number. The packets stay in the buffer for a fixed latency to compensate for possible network jitter and / or packet reordering. The combination of timestamp packet-processing, remote clock recovery and synchronization, fixed-latency receiver buffering, and error correction mechanisms help to preserve the quality of the received video, despite the significant network impairments generally encountered throughout the Internet and wireless networks.

Print job assignment method allowing user-prioritization

A method implemented in a print job management apparatus for processing print jobs in a multiple-printer print shop environment is described. Each print job specifies job ticket parameters representing printing requirements. Each received job is processed by comparing the printing requirements of the job with capabilities of the printers. If a printer cannot satisfy all printing requirements of the job, it is eliminated as a candidate printer. Then, from all printers that can satisfy all printing requirements of the job, one printer is selected based on a pre-defined priority preference and the job is submitted to the selected printer. The printer priority preference is created by the operator based on cost and other factors. The operator can also select an alternative execution mode where, among all printers that can satisfy all requirements of the job, the one with minimum wait time is selected.

Low latency data encoder

InactiveUS6725412B1Reduce codeword-position-caused latencyPromote lowerSpeech analysisCode conversionAlgorithmLow delay
Codeword-position-caused encoder latency is reduced by avoiding the requirement for knowledge of the message prior to generating an error detecting or concealing codeword associated with the message. A pseudo error detecting or concealing codeword is inserted in place of the normal error detecting or concealing codeword appropriate for the segment of information to which the error detecting or concealing codeword relates. In order to satisfy the requirement of conventional decoders, the pseudo error detecting or concealing information must match or be appropriate for the segment so that the decoder sees the codeword and message segment as valid or error free. This is accomplished by modifying or perturbing at least a portion of the segment to which the pseudo codeword relates. The invention is particularly useful for maintaining the backward compatibility of audio data encoding formats in which the minimum latency is too long (e.g., computer games, where the player performs some operation leading to a sound, and that sound must not be perceptibly delayed with respect to the operation).

Communications interface between clock domains with minimal latency

A network switch system (10) is disclosed, in which a plurality of switch fabric devices (20) are interconnected according to a ring arrangement, each of the switch fabric devices (20) including therein switch interfaces (22) coupled to corresponding network switches (14, 16). Each switch fabric device includes a plurality of ring paths (24), each of which is associated with a receive ring interface (26R) and a transmit ring interface (26X). Each ring path (24) includes a circular buffer (44) having a plurality of entries, each of which is associated with valid logic (50). The valid logic (50) for each entry presents valid signals on valid lines (WV, RV) to the receive and transmit domains of the ring path (24), and receives signals on write and read word request lines (WRW, RDW) therefrom. Control of the access to the circular buffer (44) is made according to the write and read word request lines (WRW, RDW) for the corresponding entries of the circular buffer (44) to which write pointers and read pointers point. The write word request line (WRW) sets the valid lines (WV, RV) for the corresponding entry in each of the two clock domains, while the read word request line (RDW) resets these valid lines (WV, RV) for that entry. Differences in clock frequency between the receive and transmit clock domains are thus compensated, with a minimum latency.

Cooling system for an internal combustion engine of a motor vehicle

InactiveUS20050081801A1Effective duration is reducingMinimal wait timeCoolant flow controlLighting and heating apparatusMinimum latencyInternal combustion engine
The invention relates to a cooling system in which the fan output is determined by an output control from the characteristic curves of the fan motor, the operating parameters of the cooling system and the reference input variables predetermined in the form of temperature levels. Different characteristic curves for the activation of the fan motor are here assigned to the different set temperature levels. If the reference input variable for the control changes, this also results in a change of the characteristic curves for activation of the fan motor. In order to prevent the fan motor starting to howl, in the event of a change in the reference input variable for the fan control the operation of the fan motor is kept constant for an adjustable minimum waiting time. During this minimum waiting time, switching over of the cooling circuit may have caused the operating parameters of the cooling system to adjust to the new reference input variable to such a degree that howling of the fan motor is no longer of concern.
