METHODS AND APPARATUSES FOR MANAGING A MULTIPATH CONNECTION
Methods, apparatuses, and systems are described for managing a multipath connection. A user device may maintain a network path of multiple network paths based on the streaming data that the user device transmits.
A base station may communicate with a wireless device. A message may be used to indicate information for a layer 1 and/or layer 2 triggered mobility (LTM) procedure. For example, a medium access control (MAC) control element (CE) may indicate various information such as a target cell for the LTM procedure, whether to perform a random access (RA) procedure toward a target cell, a TA value, a bandwidth part (BWP) of BWPs of the target cell, and/or other information associated with the LTM procedure.
A wireless device may receive a message indicating that it is to switch cells, such as in a handover process, and the wireless device may take steps to switch cells. The time needed for making the switch can depend on, for example, the time it takes the wireless device to process that message, and different types of messages (e.g., messages at a media access control - MAC - layer) may be processed more quickly than others. A wireless device may quickly cancel a triggered power headroom report (PHR) procedure for an old cell, and trigger a PHR for a new cell, based on receiving such a message. The canceling and/or triggering may be performed even without resetting a MAC entity of the wireless device.

Methods are described for managing transmission resources using user group correlation. A content provider or an advertiser may send, to a network provider, a content item that is to be transmitted to a target audience. The content provider or the advertiser may indicate the target audience by providing data identifying one or more criteria for the target audience. The network provider may use the data from the content provider to determine an initial user group that matches the criteria, and one or more additional user groups that are similar to the initial user group within a threshold. The network provider may transmit the content item to the initial user group and to the additional user groups.
A wireless device may communicate with a base station by using overlapping transmissions. A transmission such as a physical uplink control channel (PUCCH) transmission (e.g., comprising uplink control information (UCI)) may be multiplexed in a repetition of a transmission such as a physical uplink shared channel (PUSCH) transmission. Information such as a channel state information (CSI) report may be multiplexed in a repetition of a transmission such as a physical uplink shared channel (PUSCH) transmission. A rule may be applied to indicate/determine which repetition, of a plurality of repetitions, comprises multiplexed information (e.g., which PUSCH repetition comprises UCI). The rule may comprise including the multiplexed information in a transmission associated with at least one of: a lowest (or highest) frequency or range of frequencies, a lowest (or highest) starting (or ending) resource block, a lowest (or highest) transmission configuration indicator (TCI) state, a lowest (or highest) TCI state index, a lowest (or highest) panel or panel index, and/or any other parameter/indicator that may differentiate a transmission (including the multiplexed information) from other transmission(s). A transmission such as a power headroom report may be multiplexed in a transmission such as a physical uplink shared channel (PUSCH) transmission. A rule may be applied to indicate/determine a value/parameter associated with a transmission. For example, the rule may be used to indicate/determine a value of a power headroom report that may indicate a pathloss reference signal used to determine the power headroom report. The rule may comprise indicating/determining a value/parameter associated with a transmission using at least one of: a lowest (or highest) frequency or range of frequencies, a lowest (or highest) starting (or ending) resource block, a lowest (or highest) transmission configuration indicator (TCI) state, a lowest (or highest) TCI state index, a lowest (or highest) panel or panel index, and/or any other parameter/indicator that may differentiate transmissions. Overlapping transmissions may comprise a plurality of transmissions of a same type/channel, such as a physical uplink shared channel (PUSCH) transmission, a physical uplink control channel (PUCCH) transmission, etc. A rule may be applied to indicate/determine power prioritization for the overlapping transmissions. For example, a rule may be used to indicate which of overlapping transmissions of a same type/channel (e.g., PUSCH, PUCCH, etc.) may be dropped or transmitted using a reduced power if the overlapping transmissions would otherwise exceed a power threshold. The rule may comprise indicating/determining power prioritization for overlapping transmissions based on at least one of: a lowest (or highest) frequency or range of frequencies, a lowest (or highest) starting (or ending) resource block, a lowest (or highest) transmission configuration indicator (TCI) state, a lowest (or highest) TCI state index, a lowest (or highest) panel or panel index, and/or any other parameter/indicator that may differentiate overlapping transmissions.

Systems, apparatuses, and methods are described for message classification and management. A message may indicate a request for placement of a content item, such as an advertisement or advertisement campaign, into one or more content streams. A message ID associated with the message may be converted to a bit vector to compare to one or more filter data sets. The comparison of the bit vector to the filter data sets may determine whether the message may correspond to a previous message, such as a previous advertisement or advertisement campaign. The message may be classified as a new message or an update message.
Encoding and/or decoding a block of a video frame may be based on a previously decoded reference block in the same frame or in a different frame. The reference block may be indicated by a block vector (BV). The BV may be encoded as difference between a block vector predictor (BVP) and the BV.

Abrégé
A content adaptation method includes: obtaining a primary metadata profile associated with a particular time point of primary content; obtaining secondary metadata profiles each associated with corresponding secondary content of a plurality of secondary content; identifying one of the plurality of secondary content associated with a secondary metadata profile having a desired similarity value with the primary metadata profile associated with the primary content; and matching the identified secondary content with the particular time point of the primary content.
A computing device may be configured to provide authorization to a first content source to provide first content to a user device. The computing device may receive a request from the first content source to identify a location of second content to be presented to the user device and respond to the request by providing an address to the first content source. At the provided address, a request for the second content from the user device may be received. When responding to the request, the computing device may retrieve information associated with the user (e.g., user preference information) from the user device. Using this information, the computing device may generate at least one parameter for selecting the second contend and send a response to the user device. The response may include an address for the second content and the at least one parameter for selecting the second content.
Aspects of the disclosure relate to routing queries to a network repository and load balancing in a network. For a network repository having a plurality of content storage sites, relative replication latency of data among a pair of content storages sites can be monitored. Data indicative of such replication latency can be distributed among the content storage sites and can be provided, for example, to a network node in a system layer. A traffic and control manager can determine routing pathways for queries based at least in part on the relative replication latency data and performance conditions of network nodes.
The features relate generally to acquiring, formatting, and distributing video content to a variety of devices in multiple geographies. Some features described herein relate to preserving the stereoscopic effect for the formatting and distribution of 3D video content. Additionally, features described herein relate to customized and/or dynamic generation of a 3D stream based on a user device and/or user preferences.
A modem system may include modems that have multiple upstream transmitters for transmitting signals upstream in a communication network. In some embodiments herein, one or more of those upstream transmitters may be retasked to transmit downstream signals for reception at devices within a modem's premises. The downstream signal may be modulated differently from its original modulation as received by the modem, and may be modulated in a manner that can be received by legacy components on the premises, such as analog televisions.

Account representatives are given access to the suspended numbers. Additionally, certain emergency inbound calls may be permitted from select numbers.
A system and method of providing content in a digital video network are disclosed. The system may detect the resolution capability of a user's device, and automatically configure electronic program guide (EPG), viewing and/or recording options accordingly. User preferences may also be used. Record and viewing requests may result in tuning to and decoding different datastreams.
A stereoscopic production solution, e.g., for live events, that provides 3D video asset distribution to multiple devices and networks is described. In some embodiments, live or recorded 3D video content may be accessible by different service providers with different subscribers/users and protocols across a network of the content provider. A first video signal corresponding to a first video feed for one eye of a viewer may be received and a second video signal corresponding to a second video feed for the second eye of the viewer may be received. The first video signal and the second video signal may be encoded. The encoded first video signal and the encoded second video signal may be transmitted independently over a network. The two video signals may be received and frame synced at an off-site location for eventual rendering to a display device.

CONTROL PLANE ARCHITECTURE FOR MULTICAST CACHE-FILL
A multicast content delivery system can use both multicast and unicast streams to efficiently use available bandwidth to deliver content. Available multicast content can be identified to gateways serving consumption devices, and the gateways can receive requests for unicast content deliver, but honor the requests with multicast group sessions.
To be accessed on different media players, requested content must be delivered in a format that is supported by the requesting device. A dynamic content packager for encrypting and packaging requested content for different requesting devices at the time of consumption is disclosed.
