20050026633, Feb 3, 2005

Filed:

Jul 28, 2003

Appl. No.:

10/628660

Inventors:

Ramabadran Raghavan - Flanders NJ, US
Vivek Kansal - Randolph NJ, US

International Classification:

H04Q007/20

US Classification:

455465000, 455561000, 455007000

Abstract:

A distributed access network architecture utilizes an undedicated public network, such as the internet, to provide connectivity between portions of the network. In one example, the public network is utilized as the communication interface between base transceiver units and an access network unit. Each of these network elements may include one or more protocol layers to facilitate communication over the public network.

Appl. No.:

13/309711

Inventors:

Bhaskar BHUPALAM - Santa Clara CA, US
Jayaraman Iyer - San Jose CA, US
Vivek Kansal - San Jose CA, US
Biswaranjan Panda - Santa Clara CA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 17/30

US Classification:

707771, 707E17028, 707E17014

Abstract:

Network operators are striving to find ways to provide stable video services amid a rapid increase in video traffic. In order to provide stable video services with constrained network resources, network operators attempted to reduce video file sizes using a content adaptation engine (CAE). However, network operators failed to efficiently readdress video flows to CAEs. This disclosure provides systems and methods for efficiently readdressing video flows to CAEs.

US Classification:

709219

Abstract:

Network operators are striving to find ways to provide stable video services amid a rapid increase in video data traffic. In order to provide stable video services with constrained network resources, network operators attempted to reduce video file sizes and to cache videos for future use. However, network operators failed to exploit user information and to leverage benefits of distributing these functionalities across the network. This disclosure provides systems and methods for efficiently delivering video and managing video caches by exploiting user information and by distributing video delivery functionalities across the network.

International Classification:

H04N 9/79

US Classification:

386298

Abstract:

Multi-tier recording to enable, for example, seek-back unique copy recording may be provided. First, content may be recorded to a time-shift buffer. Recording instructions may be received and a virtual recorder corresponding to a user may be instantiated. Next, content from the time-shift buffer may be obtained according to the received recording instructions. Then the obtained content may be saved to the instantiated virtual recorder.
