A method and apparatus control receiving media data in a transmission system. A method of operating a receiving entity in the transmission system includes receiving packets for media data and information about a fixed delay associated with the media data. The method also includes identifying a requirement configured to guarantee that the packets for the media data are delivered to an upper layer of the receiving entity after the fixed delay, from the information about the fixed delay. The method further includes identifying a buffer size requirement for the receiving entity estimated based on the fixed delay and bitrate information associated with the media data; and delivering the packets to the upper layer of the receiving entity.

Methods and devices for managing devices not directly accessible to device management server are provided. A device for communicating a Location Update Alert message to a Device Management (DM) Server via a DM Gateway includes a memory for storing code of a DM client and a plurality of DM MOs, each of the plurality of DM MOs including one or more nodes, a processor for executing the code of the DM client stored in the memory, a communications unit for receiving and sending messages for the DM client, and the DM client for communicating a Location Update Alert message to the DM Server via the DM Gateway upon detecting a change in an address of the device, based on a LocationUpdate node of at least one of the plurality of DM MOs.

A method includes calculating a complexity value for each segment or version of multimedia content. The multimedia content has multiple versions associated with common content and different encoding parameters, and each version is divided into segments. The method also includes adaptively streaming the multimedia content to a client device based on at least some of the calculated complexity values. The complexity value for each segment or version is calculated by summing multiple operation complexity values defining complexities of operations for decoding the segment or version. The operation complexity values could include values for a bit parsing operation, a buffer initialization operation, an intra-prediction operation, an inverse quantization and transform operation, a reference block fetch operation, a fractional interpolation operation, and in-loop deblocking operation, a sample adaptive offset correction operation, an adaptive loop filtering operation, and a de-ringing filtering operation.

To reduce communication costs and computational complexity, only a subset of ranked SIFT points within a query image for a visual search request is transmitted to the visual search server in each iteration of an incremental search. For each candidate match, a flag identifying the matching points is returned by the server for use in computing holistic (e.g., histogram) information for a bounding box within the query image including the matching points. Distance from that query image holistic information is used to reject images from a short list used for a subsequent iteration, if any. If all images are rejected or a match criteria is met during one iteration, the search may terminate early without consideration of remaining SIFT points.

Incremental visual query processing with holistic feature feedback

To improve feature selection accuracy during a visual search, interest points within a query image are two-way matched to features in an affine transformed image or otherwise transformed version of the query image. A user device implements a method for selecting local descriptors in the visual search. The method includes: detecting a first set of interest points for the original image; computing an affine transform matrix; computing a new image as a transformation of the original image using the affine transform matrix; detecting a second set of interest points from the and new image; performing a two-way matching between the first set of interest points and the second set of interest points; sorting matching pairs according to a specified self-matching score (SMS); assigning an infinite value to SMS of unmatched interest points from the original image; selecting the interest points based on SMS. Significant performance gains reduce false positive matches.

A device for use in a communication system and a method for its operation are provided. The method of operating a Device Management (DM) client of a device in a communication system includes receiving an out-of-band DM message from a DM server, determining if out-of-band message response (OOBMsgResponse) reporting is inhibited based on an OOBMsgResponse node in a Management Object (MO), and if it is determined that OOBMsgResponse reporting is not inhibited, sending a response message in response to the out-of-band DM message received from the DM server.

A system for an in-service software upgrade is disclosed. The system consists of a processor, a first version of a software process, a second version of the software process, and a proxy software process. When executed by the processor, the proxy software process can intercept a message intended for the first version and direct the message to either the first version or the second version based on the status of a transaction associated with the message.

A system is provided that includes a manager device that executes a Simple Network Management Protocol (SNMP) manager. The system also includes an agent device coupled to the manager device. The agent device executes a SNMP agent that selectively provides access to managed data. The SNMP manager enables a user to issue a login command. The SNMP agent processes the login command and, if the user is authenticated, allows the user to access the managed data using a session identifier.

A system and method of identifying loose patterns using a smart multiset intersection operation are provided. Data segments are received from a data segmentation algorithm and sorted into corresponding multisets. A retain operation may be performed on the multisets. A normalization operation is then performed on the repeating elements in the multisets to identify the loose pattern. The loose pattern is stored in a database.
