Methods for monitoring quality metrics of a video session transmitted over a mobile video delivery network facility are disclosed. A method for monitoring quality of a video system that uses traffic transmitted over a mobile video delivery network facility may include tapping, by a video quality probe, into a mobile network traffic stream transmitted over the mobile video delivery network facility, filtering, by the video quality probe, the tapped mobile network traffic stream to identify an individual video session; and determining, by the video quality probe, a video quality parameter corresponding to the identified individual video session.

A system receives one or more content streams for a program including a Hypertext Transfer Protocol (HTTP) Live Streaming (HLS) master manifest file for the program, HLS media segments having different bitrate variants, and HLS media manifest files for each of the different bitrate variants. The system encapsulates the HLS master manifest file, the HLS media segments, and the HLS media manifest files into Internet Protocol/User Datagram Protocol (IP/UDP) packets and sends the IP/UDP packets via multicast to video serving offices. Network devices in the video serving offices extract from the IP/UDP packets the HLS master manifest file, the HLS media segments, and the HLS media manifest files. The network devices send to a cache device the HLS media segments and the HLS media manifest files; and forward the IP/UDP packets via multicast to devices in customer premises.

Aspects of the subject disclosure may include, for example, accessing a terrestrial content service that delivers media content to premises of a subscriber for presentation to media processing equipment of the subscriber. An interruption in the terrestrial content service is determined that interrupts the delivery of the media content item to the media processing equipment. An alternative media content item is identified based on the media content item, wherein the alternative media content item is available by way of a direct broadcast satellite service not subscribed to by the subscriber. The direct broadcast satellite service is provisioned to the media processing equipment responsive to the determining of the interruption in the terrestrial content service. Other embodiments are disclosed.

A multimedia stream may be abandoned (e.g., terminated) under various contexts. Metadata surrounding the abandonment, such as information regarding multimedia segments shown at or near the time of abandonment, may be stored. A system may detect satisfaction of a condition based at least in part on abandonment metadata associated with an abandoned stream, obtain a set of abandonment metadata sharing a characteristic in common, and determine a cause. Depending on the determined cause, various mitigations may be executedfor example, if abandonment of streams is detected in a specific location at a particular point or period in time, one or more network diagnostics tests may be executed to determine whether there are network connectivity issues for viewers from the specific location.

Disclosed are various embodiments for facilitating uninterrupted playback of video streams using lower quality cached files. A video file corresponding to an entirety of a video content feature encoded at a first quality may be obtained from another client on a local network. A video stream corresponding to the video content feature encoded at a second quality higher than the first quality is then obtained. The video stream is rendered for playback on a display. In response to detecting an unavailability of the video stream at a particular time in the video content feature, the video file is rendered for playback on the display in place of the video stream and commences at the particular time in the video content feature. The video file may then be sent to yet another client on the local network.

A system and method for advanced Wi-Fi performance monitoring, comprising an agent application operating on a mobile device in background operation to monitor device state and operation and test network performance during ideal times, and that presents results in an easy-to-read single-page user interface for data viewing. Test results may be logged in a database and shared across devices to enhance their own test data by filling in missing information, and may be used to form a broad representation of network performance that may be used to notify devices of performance issues or outages.

Systems and methods are described for viewing missed media content. A media content stream is received at a user device. A first timestamp is logged, in response to determining a first failure in the receiving of the content stream, indicating when the first failure in the receiving of the content stream to the user device occurred. A second timestamp is logged, in response to determining a first restoration of the receiving of the content stream, indicating when the first restoration in the receiving of the content stream to the user device occurred. A first recorded portion of the media content stream is retrieved. The first recorded portion has a start point corresponding to the first timestamp and an end point corresponding to the second timestamp.

A monitoring device includes a video buffer model and a user model. The video buffer model monitors a media program streaming across a network to a media client for perceivable transmission impairments. The user model reflects user dissatisfaction due to types of perceivable transmission impairments and timing, duration, and frequency of perceivable transmission impairments so as to estimate a quality of experience of the media program. The parametric model can include one or more parameterized functions, and a set of parameters used in at least one of the one or more of the parameterized functions at a point in time during the streaming of the media program can be based on a type of perceivable transmission impairment associated with the point in time.

Disclosed are a method and an apparatus for generating a codeword, and a method and an apparatus for recovering a codeword. An encoder calculates the number of punctured symbol nodes among symbol nodes included in a codeword, punctures symbol nodes located at even or odd number positions among the symbol nodes included in the codeword, calculates the number of symbol nodes which need to be additionally punctured on the basis of the calculated number of the symbol nodes to be punctured, classifies the symbol nodes, which need to be additionally punctured, into one or more punctured node groups on the basis of the calculated number of symbol nodes which need to be punctured, determines the locations on the codeword where the one or more punctured node groups are to be arranged, and punctures the symbol nodes included in the codeword which belong to the punctured node groups according to the determined locations. A transmission unit transmits the codeword.

In response to detecting an unavailability of the video stream at a particular time in the video content feature, the video file is rendered for playback on the display in place of the video stream and commences at the particular time in the video content feature. The video file may then be sent to yet another client on the local network.
