Publication number: 20200389678Abstract: Methods and systems are disclosed for delivery of one or more channels of programming in an IP network. An edge gateway device may retrieve segments of programming, based on information in a manifest file, and output the segments via multicast to one or more edge devices. Advertising content may be inserted, or replaced if already present, before the segments are multicast. Segments encoded at various bit rates may be available for retrieval. Segments may be selected for retrieval based in part on a quality indicator associated with each segment.Type: ApplicationFiled: January 7, 2020Publication date: December 10, 2020Inventors: Weidong Mao, Robert Gaydos

Publication number: 20200382819Abstract: Cache management techniques are described for a content distribution network (CDN), for example, a video on demand (VOD) system supporting user requests and delivery of video content. A preferred cache size may be calculated for one or more cache devices in the CDN, for example, based on a maximum cache memory size, a bandwidth availability associated with the CDN, and a title dispersion calculation determined by the user requests within the CDN. After establishing the cache with a set of assets (e.g., video content), an asset replacement algorithm may be executed at one or more cache devices in the CDN. When a determination is made that a new asset should be added to a full cache, a multi-factor comparative analysis may be performed on the assets currently residing in the cache, comparing the popularity and size of assets and combinations of assets, along with other factors to determine which assets should be replaced in the cache device.Type: ApplicationFiled: June 11, 2020Publication date: December 3, 2020Inventors: Volnie Whyte, Amit Garg, Tom Brown, Robert Gaydos, Mark Muehl

Publication number: 20200343988Abstract: Systems, apparatuses, and methods are described for synchronization based on time differentials in an access network. A time domain may be established for a virtual service and a remote node. The virtual service may synchronize to a clock associated with the remote node based on a time differential. Various virtual services may maintain their own time domains with remote nodes.Type: ApplicationFiled: April 29, 2019Publication date: October 29, 2020Inventors: Nagesh Nandiraju, Robert Gaydos

Publication number: 20200329269Abstract: A network digital video recording (nDVR) system may take into account the capabilities of a requesting user's local DVR when managing network recordings. The user's local DVR may include a temporary buffer that is normally used to record what the DVR is tuned to, and may be used for local trickplay functionality such as pausing live television. The nDVR features described herein may track the usage of the user's temporary DVR buffer, and use that in determining what to stream in response to a user's playback request. The nDVR system can also determine if the user's local DVR has an unused tuner at a time of a program recording, and can instruct the user's local DVR to also tune to the program.Type: ApplicationFiled: April 29, 2020Publication date: October 15, 2020Inventors: Todd Walker, Bruce Bradley, Thomas Day, Robert Gaydos, John Leddy, Weidong Mao

Patent number: 10349132Abstract: A method and system of limiting recording demands on digital video recorders and other media records. The limiting being facilitated through analysis of programs and other media available from one or more network resources associated with and/or having capabilities to provide media to the recording element. The network resources may be associated with provider resources, customer resources, and/or any other resource in communication with the recording element.Type: GrantFiled: August 11, 2014Date of Patent: July 9, 2019Assignee: Comcast Cable Communications, LLCInventors: Derek T.

Publication number: 20180192327Abstract: Described herein is a system and method for a microservices architecture for dynamic channel migration based on real time traffic load. Traffic loads on a first and second radio frequency (RF) channels used by a transceiver to communicate with a plurality of modem devices may be monitored, where the first RF channel is transmitted at a higher frequency than the second RF channel. Based on the monitored traffic loads of the RF channels, data traffic may be migrated from the first RF channel to the second RF channel. Finally, the plurality of modem devices may be notified of the migration.Type: ApplicationFiled: December 29, 2017Publication date: July 5, 2018Applicant: Comcast Cable Communications, LLCInventors: Robert Gaydos, Nagesh Nandiraju

Publication number: 20150242500Abstract: An archive model can be used for managing networked storage of recorded content, such as network DVR (digital video recorder) content. Content may be initially recorded to an active storage device, with individual duplicate copies recorded for each requesting user, and subsequently archived to an archive storage device. For playback, the content can be reconstituted into the active storage device prior to delivery to the requesting user. Content can be predictively reconstituted in anticipation of user needs, and the reconstitution capacity of the system can be dynamically reallocated for load balancing.Type: ApplicationFiled: February 25, 2015Publication date: August 27, 2015Inventors: Todd Walker, Bruce Bradley, Thomas Day, Robert Gaydos, John Leddy, Weidong Mao
