Abstract: Systems and methods for prioritizing adaptive bit rate distribution of content are provided. In some aspects, a method includes identifying a plurality of content streams. Each of the plurality of content streams is associated with a variant feature of content to be delivered to the client device. Each variant feature of the content comprises at least one of a bit rate and a non-bit rate feature. The method also includes determining a priority of each of the plurality of content streams relative to one another based at least on the non-bit rate feature associated with each of the plurality of content streams. The method also includes providing an indication of the priority of each of the plurality of content streams to the client device.

Abstract: A content distribution system may include a headend server and media converters, the headend server being configured to distribute content items to user devices via the media converters and gateway devices. Each of the media converters may include a media converter cache and may be coupled to the headend server and a subset of the gateway devices, where each of the user devices is communicatively coupled to one of the gateway devices. The headend server may be further configured to determine one of the content items that is expected to be requested by a group of the user devices, determine one of the media converters that is coupled, via the subset of the gateway devices, to a largest number of user devices in the group of the user devices, and coordinate storing the one of the content items in the media converter cache of the one of the media converters.

Abstract: Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures distribute data streams to bonded channels that are clocked independently. A system is provided for synchronizing the bonded channels.

Abstract: A system for transmitting multiple adaptive bit rate (ABR) segment streams on a shared frequency may include an ABR segment generator and transmitter circuitry. The ABR segment generator may encode a content item based at least in part on different ABR profiles to generate encoded streams. The ABR profiles may indicate encoding parameters corresponding to the encoded streams, e.g., bit rates, resolutions, frame rates and/or codecs. The ABR segment generator may be further configured to segment the encoded streams to generate ABR segment streams. The transmitter circuitry may be configured to transmit the ABR segment streams on a shared frequency, such as by transmitting the segment streams over spatially separated antennas, or by applying different orbital angular momentums to the ABR segment streams. In one or more implementations, the system may further include a segment interleaver that is configured to interleave the ABR segment streams.

Abstract: A broadband gateway, which enables communication with a plurality of devices, handles at least one physical layer connection to at least one corresponding network access service provider. The broadband gateway determines network channel conditions for a requested service and identifies a user profile for a requesting device. The broadband gateway negotiates a service profile for the requested service with the at least one network access service provider based on the determined network conditions and the identified user profile. Content may be acquired and received for the requested service from the at least one network access service provider utilizing the negotiated service profile. The broadband gateway aggregates and assembles the received content. The resulting assembled content is communicated to the requesting device for the requested service. The broadband gateway may relay content among peer devices. Content conversion may be performed during the relay communication to match user profiles of subsequent peer devices.

Abstract: A monoscopic camera comprising one or more image sensors and a depth sensor may generate video based on two-dimensional image data captured via the one or more image sensors and corresponding depth information captured via the depth sensor. The camera may process corresponding audio for the generated video based on the captured depth information. The audio processing may comprise mitigating noise in the corresponding audio, enhancing voice quality in the corresponding audio, and/or enhancing audio quality of the corresponding audio. The camera may be operable to determine, based on the captured depth information, one or more sound paths between a source of the corresponding audio and a microphone utilized to capture the corresponding audio emanating from the source. The processing of the audio may comprise removing portions of the captured audio arriving at the microphone via one or more reflection paths.
