Abstract:
A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server. A client device can be adapted to take advantage of the ingestion process. The client device might be configured to optimize use of resources, given the information available to it from the ingestion system. This may include configurations to determine the sequence, timing and construction of block requests based on monitoring buffer size and rate of change of buffer size, use of variable sized requests, mapping of block requests to underlying transport connections, flexible pipelining of requests, and/or use of whole file requests based on statistical considerations.
Abstract:
The present invention discloses a method for obtaining a service list and multimedia broadcast multicast service data, and the method includes: obtaining electronic service guide (ESG) information, receiving a system information block (SIB)13 from system information, and obtaining a cell service list according to the ESG information and the SIB 13. The present invention also discloses a system for obtaining a service list and multimedia broadcast multicast service data; in the system, a cell service list acquisition unit is configured to obtain ESG information, receive an SIB 13 from system information, and obtain a cell service list according to the ESG information and the SIB 13. With the method and system in the present invention, the cell service list can be acquired, and the receiving of data of multimedia broadcast multicast service (MBMS) service can be achieved after obtaining the cell service list.
Abstract:
Regioselectively substituted cellulose esters having a plurality of aryl-acyl substituents and a plurality of alkyl-acyl substituents are disclosed along with methods for making the same. Such cellulose esters may be suitable for use in optical films, such as optical films having certain Nz values, −A optical films, and/or +C optical films. Optical films prepared employing such cellulose esters have a variety of commercial applications, such as, for example, as compensation films in liquid crystal displays and/or waveplates in creating circular polarized light used in 3-D technology.
Abstract:
A method for scheduling communication traffic in an Advanced Telecom Computing Architecture based equipment and a corresponding apparatus are provided. In the method, communication traffic information of traffic processing means in the equipment is collected; based on the collected communication traffic information, a traffic distribution rule for the traffic processing means in next time period is generated; and based on the generated traffic distribution rule, incoming communication traffic of the equipment is scheduled. The method of the invention considers the quality of service and contracted capacity of the whole equipment and the dynamic processing capability and running environment of the traffic processing means, and can balance the loads of the respective traffic processing means in the equipment with asymmetric multi-application configuration well by adaptively adjusting the distribution of the communication traffic, to guarantee the quality of service of the whole equipment.
Abstract:
A control apparatus for a power quality device comprises: a power quality analysis module, for sampling a power supply network to obtain a power quality information, and performing an analysis and computing on the sampling, so as to output an instruction information; N tracking control modules, for receiving respectively the instruction information and tracking the instruction information, so as to output N PWM control signals having a same frequency and constant phase shift therebetween, where N is a positive integer and N≧2, thereby to control the power quality device; wherein the power quality analysis module and the N tracking control modules are operated based on a synchronized signal.
Abstract:
A method for casting a styrenic fluoropolymer film on a substrate includes preparing a polymer solution by dissolving the fluoropolymer in a solvent or solvent blend whose Hansen solubility parameters (HSPs. MPa1/2) satisfy the following relations: |SPb−SPp|

Methods of using compounds of Formula (I) and stereoisomers and pharmaceutically acceptable salts thereof, for in vitro, in situ, and in vivo diagnosis, prevention or treatment of such disorders in mammalian cells, or associated pathological conditions are disclosed.
Abstract:
Techniques for improved feature detection are described. In one embodiment, for example, a device may include a processor circuit and a feature detection module, and the feature detection module may be operative on the processor circuit to perform a first feature detection iteration for a graphics information element using an integral pixel value array, determine a scaling factor, recalculate the integral pixel value array based on the scaling factor, and perform a second feature detection iteration for the graphics information element using the recalculated integral pixel value array. Other embodiments are described and claimed.
Abstract:
A method and a system for refreshing addresses are disclosed. Said method includes: when state switching between a link fault and a fault recovery occurs in a link, a node where a port related to this link is situated refreshing an address forwarding list, and configuring a flag PF for suspending an operation of refreshing an address forwarding list on other ports of this node, and sending protocol message with address refreshing information to other nodes; and when ports of other nodes receive said protocol message, refreshing the address forwarding list only when identifier information included in this protocol message is inconsistent with identifier information stored in this port and this port is not configured with said PF flag. Said method and system judge whether to refresh the address forwarding list according to said PF flag, and determine whether to refresh the address forwarding list according to the judgment result.
Abstract:
The present invention provides a method and an apparatus for acquiring protocol messages by a ring-network node, including: using dual fields to identify different protocol messages; if a node supporting G.8032v1 receives a Force Switch (FS) or Manual Switch (MS) protocol message, determining that message is a Signal Fail (SF) protocol message according to an identifier; a node supporting G.8032v2 determining that the received protocol message is an SF or MS or FS protocol message according to the identifier. The method of the present invention enables the nodes in a ring network to accurately control the state of their own ports, thereby avoiding the case that multiple blocking points appear in the ring network and improving the network performance.
