Aspects of the subject disclosure may include, for example, a device including a processing system including a processor and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, including monitoring network traffic to determine a transmission control protocol traffic pattern, determining a target video rate from the transmission control protocol traffic pattern, and modifying an over-the-top video delivery service network according to the target video rate. Other embodiments are disclosed.

Method and apparatus for managing over-the-top video rate

In one example, the present disclosure describes a device, computer-readable medium, and method for estimating the streaming rate at which data is delivered over a network. For instance, in one example, a data packet is intercepted from a data streaming session conducted between a first device and a second device connected over a network. A size of a file segment contained in the data packet is calculated. The file segment corresponds to a portion of an item of multimedia content being delivered via the data streaming session. The encoding rate of the data streaming session is then calculated based at least in part on the size of the file segment.

Estimating network data streaming rate

Aspects of the subject disclosure may include, for example, a method in which an end user device sends a first request to a digital video recorder (DVR) to receive a media content item, and receives a metadata file including authentication information and a network address of a media content server where the media content item is located. The end user device sends a second request to the media content server to receive the media content item; the second request is sent to the network address and includes the authentication information and an identification of the requested media content item. The end user device receives the media content item from the media content server, responsive to the authentication information and the identification of the media content item sent in the second request. Other embodiments are disclosed.

Method and apparatus for obtaining recorded media content

In one example, the encoding rate at which data is delivered over a network is estimated by intercepting a data packet from a data streaming session, wherein the data packet contains at least a portion of one of a plurality of file segments containing portions of a file, and wherein a number of the plurality of file segments that is delivered via the data streaming session is limited to a maximum number. The mean size of the plurality of file segments is estimated from data contained in the data packet. A plurality of potential sizes of the plurality of file segments is calculated, wherein each potential size corresponds to one number between one and the maximum number. An encoding rate of the data streaming session is calculated, based at least in part on which potential size of the plurality of potential sizes is closest to the mean size.

Estimating network data encoding rate

Aspects of the subject disclosure may include, for example, a system that provides for obtaining, by a server comprising a processor, network parameter data from an eNodeB of a wireless network. The server can determine a predicted bandwidth for a group of end user devices in a coverage area of the eNodeB according to the network parameter data. The server can receive, from an end user device of the group of end user devices, a request for the predicted bandwidth. The server can provide the predicted bandwidth to the end user device. The providing of the predicted bandwidth enables the end user device to provide a video chunk request to a content server that is based on a selected chunk delivery schedule and facilitates streaming of video content to the end user device from the content server. Other embodiments are disclosed.

Apparatus and method of video streaming

Aspects of the subject disclosure may include, for example, a method comprising: sending by an end user device, to a digital video recorder, a first request to receive a requested media content item; receiving by the end user device, responsive to the sending of the first request, a metadata file, wherein the metadata file comprises authentication information and a network address of a media content server where the requested media content item is located; sending to the media content server by the end user device, responsive to the receiving of the metadata file, a second request to receive the requested media content item, wherein the second request is sent to the network address, wherein the second request comprises the authentication information contained in the metadata file, and wherein the second request comprises an identification of the requested media content item; and receiving by the end user device, responsive to the authentication information and the identification of the requested media content item that are sent in the second request, the requested media content item from the media content server. Other embodiments are disclosed.

A system and method of delivering video content is disclosed. In a particular embodiment, the method includes receiving channel selection data from a set-top box device via an Internet Protocol Television (IPTV) access network. The channel selection data indicates a selection of an IPTV channel. The method also includes sending a rapid channel change (RCC) request to a distribution switch/router system via a subscriber virtual local area network (VLAN) associated with the set-top box device after receiving the channel selection data. The RCC request indicates the selected IPTV channel.

System and method of delivering video content

A method includes receiving, at a server, a retry request from a media device. The retry request requests a data packet associated with video content and includes an overhead bandwidth factor corresponding to a ratio between an overhead bandwidth to be used to send the data packet in response to the retry request and a nominal bandwidth used to send video content to the media device. The method further includes, in response to the retry request, sending the data packet to the media device based on the overhead bandwidth factor.

A method includes receiving an indication of at least one detected security issue at a network device. The indication is received at a security manager processor from a security agent. The method includes selecting, via the security manager processor, at least one executable security object responsive to the indication. The security manager processor verifies compatibility between the at least one executable security object, the network device, and communication media. The method also includes sending the at least one executable security object to the network device via the security manager processor to provide a protective security measure to the network device against the at least one detected security issue upon execution of the at least one executable security object.

System and method for providing network security

A method includes receiving at a set-top box device first video content associated with a requested channel from a first source. The method includes, in response to receiving the first content, requesting second video content associated with the requested channel from a second source. The method includes, in response to receiving the second video content, determining whether at least one data packet associated with the requested channel was not received based on a comparison of first data packets corresponding to the first video content and second data packets corresponding to the second video content. In response to a determination that at least one data packet was not received, sending a retry request to the first source. The retry request includes an overhead bandwidth factor.

A method includes receiving data from a set-top box device at an access system via an access network, the data indicating a selection of a channel at the set-top box device, the data including a multicast group address. The method also includes sending copies of video data packets of the channel from the access system for storage in a first-in first-out cache associated with the channel. The method further includes automatically connecting the set-top box device to a multicast stream of the selected channel after a particular number of video data packets are sent to the set-top box device from the cache. The particular number of video data packets corresponds to a time period between communicating successive random access point packets of the channel and is less than a capacity of the cache.
