G06F 15/173
G06F 15/173
US Classification:
709231, 709223, 709246
Abstract:
A method includes receiving a media request for a target device. The signaling information may be received from the target device and a media server. At least one attribute of the target device and the media server may be identified using the signaling information. At least one attribute of the target device and the media server may be evaluated against a service level objective to select a media format. The service level objective may include consideration of the target device and available bandwidth over a provider network. The media may be provided in the selected media format over the provider network to the target device.

International Classification:
G01R 31/08
US Classification:
370252, 370229, 370258, 370238
Abstract:
Various embodiments of the disclosed subject matter provide methods and systems to generate node-disjoint routing paths from a root node to each node in a network node set, identify potential intermediate office node (IO) candidate pairs from the generated node-disjoint routing paths, generate a per central office node (CO) serving cost estimate for each IO candidate pair, and identify a low cost IO candidate pair having at least two node-disjoint paths to the root node without traversing nodes along a diverse path between the low cost IO candidate pair and subtending CO nodes.

Methods And Apparatus To Allocate Bandwidth Between Video And Non-Video Services In Access Networks
US Patent:
7921212, Apr 5, 2011
Filed:
Oct 14, 2008
Appl. No.:
12/251130
Inventors:

International Classification:
G06F 15/173
US Classification:
709226, 709223, 709224
Abstract:
Example methods and apparatus to allocate bandwidth between video and non-video services in access networks are disclosed. An example system comprises a customer-premises device, a digital subscriber line access multiplexer (DSLAM) to transmit to the customer-premises device a signal having a non-video portion and a video portion, a usage monitor at the customer-premises device to monitor a usage of the video portion and to send a parameter representative of the usage of the video portion to the DSLAM, and a policy manager at the DSLAM to adjust at the DSLAM a bandwidth allocation between the video portion and the non-video portion based on the parameter.

International Classification:
H04N 7/173
US Classification:
725 94, 725 93, 725 95, 725 96
Abstract:
A method for redirecting video content includes receiving a video signal at the set-top box and decoding the video signal to produce unrendered video data. The unrendered video data is encoded and provided to the remote device via a wide area network. By encoding unrendered, rather than rendered, video data for transmission to the remote device, the need for an encoding device external to the set-top box is obviated.
