Frames of a video stream collected at first and second points along a video delivery chain are buffered into first and second buffers, respectively, the second point being downstream the video delivery chain from the first point. A control group is identified as a subset of frames of the second buffer. Correlations of extracted features of the control group to extracted features of successive windows of frames of the first buffer are computed, the extracted features being based on spatial information and temporal information of the video stream. A delay between the video stream collected at the first point and the video stream collected at the second point is identified according to a maximum correlation of the correlations.

Aspects of the subject disclosure may include, for example, obtaining, from a first source of information, a first bandwidth prediction, wherein the first bandwidth prediction is based upon historical bandwidth data that had been provided by a plurality of devices; obtaining, from a second source of information, a second bandwidth prediction, wherein the second bandwidth prediction is based upon network measurements, and wherein the network measurements are other than the historical bandwidth data that had been provided by the plurality of devices; selecting as a source of a future bandwidth prediction one of the first source of information and the second source of information, wherein the selecting is based upon a comparison of each of the first bandwidth prediction and the second bandwidth prediction to an actually obtained bandwidth of the device. Other embodiments are disclosed.

Systems, apparatuses, and methods are described for controlling quality of service (QoS) provided to user devices by, for example, requesting a portion of the user devices to temporarily and selectively downgrade a quality of service. A downgrade message may be sent to the user devices to request a downgrade, and may provide information to allow the user devices to determine whether they will abide by the requested downgrade.

Other embodiments are disclosed.

Disclosed is a method of managing congestion by a Policy Control and Charging Rules Function (PCRF). The method includes receiving at least one piece of video flow related information; receiving, from an evolved Node B (eNB), congestion state information for the eNB and at least one User Equipment (UE); determining a data transmission rate of at least one video flow on the basis of the received congestion state information and the received video flow related information; and adjusting the data transmission rate of the at least one video flow on the basis of the determined data transmission rate.

The Distributed Software Defined Network (dSDN) disclosed herein is an end-to-end architecture that enables secure and flexible programmability across a network with full lifecycle management of services and infrastructure applications (fxDeviceApp). The dSDN also harmonizes application deployment across the network independent of the hardware vendor. As a result, the dSDN simplifies the network deployment lifecycle from concept to design to implementation to decommissioning.

A method, non-transitory computer readable medium and apparatus for changing a quality of service for data packets that are delivered over-the-top are disclosed. For example, the method includes a processor that identifies the data packets as video data packets that are delivered over-the-top in a communication network, changes the quality of service associated with the data packets from a best effort quality of service level to a higher priority quality of service level, monitors the data packets until no video data packet is identified in the data packets and changes the quality of service associated with the data packets back to the best effort quality of service level from the higher priority quality of service level.

Provided is a method and system for generating a network bandwidth adaptive content, the method including: measuring bandwidth information of a transmission channel formed between a content server and a reception terminal; generating a target content by converting a source content to be transmitted to the reception terminal, at a transmission bitrate that is determined based on the bandwidth information; transmitting the generated target content to the reception terminal; and storing information on the target content in a dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH) media presentation description (MPD) file.

Systems, devices and processes are provided to facilitate the delivery of video content in a video streaming system by facilitating the diagnosis and repair of internet gateway devices used in such video streaming systems. Specifically, the various embodiments provide a mechanism by which an end user of video streaming system can initiate the diagnosis and/or repair of the internet gateway device while maintaining the security of the internet gateway device and the video streaming system. More specifically, a help button is provided on the internet gateway device that facilitates the establishment of a secure network session between the internet gateway device and a help center associated with the video streaming system. This secure network session facilitates the diagnosing of operational errors associated with the internet gateway device and thus can facilitate the effective repair and operation of the video streaming system while maintaining device security.

Aspects of the subject disclosure may include, for example, detecting a communication session from each of a group of communication devices over a portion of a communication network resulting in a group of communication sessions. Each communication device of the group of communication devices is associated with a user. Further embodiments include determining each communication session comprises downloading of a group of short-form video content from a video content server over the portion of the communication network, and identifying a group of network traffic features associated with the group of communication sessions. Additional embodiments include providing first instructions to a network device based on the group of network traffic features. The network device adjusts a group of network resources according to the first instructions. Other embodiments are disclosed.
