Patent number: 10182269Abstract: 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.Type: GrantFiled: April 24, 2018Date of Patent: January 15, 2019Assignee: Verizon Patent and Licensing Inc.Inventors: Niranjan R. Samant, Suri B. Medapati, James F. Di Mattia, Kishore Tallapaneni

Patent number: 10015528Abstract: A server structure (101) includes one or more multicast servers (106). An analytics engine (207) determines one or more channel maps (217) identifying a group of channels that will be delivered by the multicast servers across a network (104). The analytics engine determines the one or more channel maps as a function of both historical data corresponding to one or more client groups (204,205,206) operating in one or more zones (201,202,203), and optionally from near real time data such as electronic program guide metadata provided by an electronic program guide metadata manager (213). A flap detector (210) can determine one or more flapping thresholds (405,406,407) identifying channels in the group of channels delivered by the multicast servers, as well as whether channels having flapping frequencies greater than the flapping threshold should remain in the group of channels delivered by the multicast servers.Type: GrantFiled: December 29, 2016Date of Patent: July 3, 2018Assignee: ARRIS Enterprises LLCInventors: Sridhar Kunisetty, Vinay Kalra, Robert Linwood Myers, Niranjan R.

Patent number: 9544628Abstract: A method and apparatus for streaming Over-the-Top (OTT) content on a network to subscribers is described. A digital video transport stream of an item of the OTT content is obtained via unicast streaming methods of a resolution and bit rate selected from an available set of different resolutions and bit rates for the digital video transport stream. The digital video transport stream of the selected resolution and bit rate is transmitted in the form of an IP multicast over the network to subscribers. Bandwidth utilization of the network is monitored so that switching of the bit rate to a different bit rate for the digital video transport stream can be controlled to provide adaptive rate control of the IP multicast.Type: GrantFiled: December 7, 2015Date of Patent: January 10, 2017Assignee: GOOGLE TECHNOLOGY HOLDINGS LLCInventors: Robert E. Mack, Lawrence D. Vince, Niranjan R. Samant

Patent number: 9161095Abstract: Systems and methods for blackout management in media distribution systems may include a central data center in a service provider's domain. The central data server may coordinate with a blackout manager that implements control features for blackout. In contrast to (or to supplement) blackout control solutions that require integrated receiver decoders (IRD)s to be physically installed at each of the regional headends in the service provider network, the blackout manager may provide three functions: 1) a Virtual IRD (VIRD) function 2) access control functions via access control component, and 3) VIRD-to-EndPoint mapping function in the linkage manager.Type: GrantFiled: February 22, 2013Date of Patent: October 13, 2015Assignee: ARRIS Technology, Inc.Inventors: Robert E.

Patent number: 8561102Abstract: A video content delivery system is provided for set top boxes (STBs) that may be relocated as well as mobile clients using the Internet to retrieve content manifest files pertaining to the geographic area in which they are located. To provide this system, the edge cache in each geo-location region of a content provider is configured to append location specific metadata to a client's original HTTP request for content, making the request geo-location or region specific. The specific metadata appended by the edge cache in each region prevent clients from bypassing blackout or other content restrictions by moving from a non-restricted area and sending inaccurate location information. In another feature of the system to prevent client bypassing of blackout restrictions, the edge cache when communicating with the STB removes any location specific information which the client provides.Type: GrantFiled: August 16, 2012Date of Patent: October 15, 2013Assignee: General Instrument CorporationInventors: Robert E.
