Abstract: Devices, computer-readable media, and methods for selecting a type of transmission for an immersive visual stream based upon a latency estimate. For instance, a processing system including at least one processor may obtain a latency estimate for an immersive visual stream, determine whether the latency estimate exceeds a latency threshold for selecting a type of transmission for the immersive visual stream, and select the type of transmission for the immersive visual stream from among a field of view restricted type of transmission and a field of view plus out of scene type of transmission based upon the determining. When the latency estimate is determined to not exceed the latency threshold, the field of view restricted type of transmission is selected. When the latency estimate is determined to exceed the latency threshold, the field of view plus out of scene type of transmission is selected.

Abstract: Aspects of the subject disclosure may include, for example, a system that provides for obtaining network parameter data from an eNodeB and a content delivery network server of a wireless network, determining a predicted network condition for a group of end user devices to receive an over-the-top video service in a coverage area of the eNodeB according to the network parameter data, and providing access to prediction information representative of the predicted network condition. The providing the access to the prediction information representative of the predicted network condition enables a video client of an end user device in the coverage area to provide a request for a video chunk to a video server according to buffer information and the predicted network condition. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a method including monitoring a video session to determine key performance indicators for cross-layer interactions between a network providing video session video data and user equipment receiving the video session video data, wherein the key performance indicators include a requested quality for a video chunk requested by the user equipment, a transmission control protocol congestion window size that corresponds to the video chunk requested by the user equipment, and an instantaneous radio access network throughput while downloading the video chunk requested by the user equipment, and determining a quality of service for the user equipment during the video session according to a residual length of content in a playback buffer for the user equipment based on the requested quality for the video chunk, the transmission control protocol congestion window size, and the instantaneous radio access network throughput. Other embodiments are disclosed.

Abstract: A method includes receiving a packet stream at a gateway device, the gateway device coupled to a component of a content distribution system. The method also includes transmitting, from the gateway device, a wireless signal that carries data corresponding to at least a portion of the packet stream to a first device. The wireless signal is transmitted in a wireless coverage area that includes a second device configured to receive and analyze the wireless signal to produce of an assessment of the content distribution system.
