Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
