Disclosed is a system and associated methods for secure media stream distribution across different platforms associated with different Internet domains. A first node of a first platform receives a first request from a device, performs a first verification based on credentials provided by the device matching stored credentials, generates a first signed token, and provides the first signed token with a second link for the device to access the requested media stream from a second network node of a second platform. The second network node determines that the device was verified at the first network node based on a second stream request from the device including the first signed token, generates a second token that uniquely identifies the device in the second domain, and streams requested stream data to the device in response to performing a second verification based on requests for the stream data including the second token.

A method, a device, and a non-transitory storage medium are described in which a power of late reverberation of a speech signal is estimated based on early samples of the speech signal. The power of the late reverberation may be subtracted linearly or non-linearly from the speech signal.

Audio processing for speech

An exemplary method includes a cloud-based service provider system detecting an input command provided by a user during a scheduling session and representative of a request for a local digital video recording ('DVR') system to record a media program during a presentation time period. In response to the detecting of the input command, the cloud-based service provider system identifies a conflict associated with the request for the local DVR system to record the media program, performs a prioritization operation to determine a relative priority of media programs that are at least one of scheduled to be recorded by the local DVR system at any given time during the presentation time period and currently recorded in a memory of the local DVR system, and automatically performs, based on the performing of the prioritization operation, a predetermined action to resolve the conflict and facilitate the local DVR system recording the media program.

Methods and systems for resolving recording conflicts in a hybrid cloud-local digital video recording system

Techniques, described herein, may enable a computing device (e.g., a set-top-box, a user equipment (UE), etc.) with an array of sensors (e.g., microphones, antennas, etc.) to engage in beamforming in a manner that optimizes the signal strength of the target signal. For example, the computing device may create an optimized beam pattern by applying a pre-selected band width to a steering direction of the target signal. The beam width may include steering vectors at equal, angular distances from the steering direction, enabling steep transition slopes to be applied to the optimized beam pattern. In some implementations, the beam width and transition slopes may be standardized, such that the optimized beam pattern for any signal may be uniform, regardless of variables such as frequency and time.

Beamforming optimization for receiving audio signals

A method, a system, and a non-transitory storage medium provides to store first recording information that indicates programs that are recorded and stored at user devices, and programs to be recorded and stored at the user devices, receive, from a user device, a message that includes second recording information, wherein the second recording information includes second data instances; compare a portion of the first recording information with the second recording information; determine whether there is a difference between each first data instance relative to each corresponding second data instance; determine a master source for each first data instance that differs from each corresponding second data instance; update each first data instance that differs, one of the network device or the user device based on the master source, and provide the DVR service based on an updated portion of the first recording information, an updated second recording information, or both.

A new approach is proposed that contemplates systems and methods to support the operation of a Virtual Media Room or Virtual Meeting Room (VMR), wherein each VMR can accept from a plurality of participants at different geographic locations a variety of video conferencing feeds of audio and video streams from video conference endpoints. A globally distributed infrastructure that supports operations of the VMR through a plurality of MCUs (Multipoint Control Unit) built from off-the-shelf components instead of custom hardware as media processing nodes, each configured to process the plurality of audio and video streams from the plurality of video conference endpoints in real time. Each single VMR can be implemented and supported across the infrastructure of globally distributed set of servers/media processing nodes co-located in Points of Presence (POPs) for Internet access, wherein such massively distributed architecture can support thousands of simultaneously active VMRs and yet is transparent to the users of the VMRs.

Systems and methods for scalable distributed global infrastructure for real-time multimedia communication

A device may receive an audio sample, and may separate the audio sample into multiple sub-band signals in multiple frequency bands. The device may modify an upper boundary and a lower boundary of at least one of the frequency bands to form modified frequency bands. The device may modify the sub-band signals to form banded signals associated with the modified frequency bands. The device may smooth the banded signals to form smoothed signal values. The device may identify peak values included in the smoothed signal values, and may generate an audio fingerprint for the audio sample based on the smoothed signal values and the peak values.

Each of the participants is offered a rich set of conferencing and collaboration interaction hitherto not experienced by video conferencing participants and a moderator of the video conference is further offered with in-meeting management and control over a plurality of security and privacy settings during the video conference. These interactions encompass controlling of a video conferencing session, its configuration, privacy, security, the visual layout of the participants, customization of the VMR and adaptation of the room to different vertical applications.
