Patent number: 11943273Abstract: A method of data conditioning is disclosed that in one aspect can include the steps of receiving a data stream, encoding a time code in the data stream to identify a portion of the data stream corresponding to a content fragment, and separating the identified portion of the data stream to define the content fragment, wherein the content fragment comprises the encoded time code.Type: GrantFiled: March 21, 2023Date of Patent: March 26, 2024Assignee: Comcast Cable Communications, LLCInventors: Jan van Doorn, Brian Field

Patent number: 11936926Abstract: Transaction activity of a cache maintaining content may be monitored to determine periods of transaction activity below a first threshold amount of transactions. A period of anticipated transaction activity above a second threshold amount of transactions may be determined. A period of anticipated transaction activity below the first threshold may be selected based upon the monitored periods of transaction activity below the first threshold and the determined period of anticipated transaction activity above the second threshold. Content then may be evicted from the cache during the selected period of anticipated transaction activity.Type: GrantFiled: June 14, 2022Date of Patent: March 19, 2024Assignee: TiVo CorporationInventors: Brian Field, Jan Van Doorn

Patent number: 11886528Abstract: Aspects of the disclosure relate to validation of a request for an asset based on information in the request. Validation of the request can be processed by a network node in a network repository that contains the asset. In one aspect, validation of the request can comprise determining if the request is legitimate based at least on processing at least a portion of the information in the request. In response to a legitimate request, the network node can process the request and, as a result, a data object associated with the asset can be supplied to a device originating the request. In the alternative, the network node can yield an exception.Type: GrantFiled: December 22, 2022Date of Patent: January 30, 2024Assignee: Comcast Cable Communications, LLCInventors: Brian Field, Jan van Doorn

Publication number: 20230370662Abstract: A monitoring and analysis system is disclosed that gathers and analyzes information about distributed enhanced content delivery to end user or other equipment. The system may establish communications connections along the content delivery system, filter content received from different locations of the system, and compare the received content with an expected content characteristic. Also, a radio frequency signal from the distribution network may be converted into an Internet Protocol (IP) format by a converter so that the transformed signal may be similarly analyzed as other signals from the system. A report may be consequently generated that is indicative of the received enhanced content and any detected discrepancies with respect to expected enhancement events. Identification of the enhanced content may be based on the program association table and the program map table in order to determine the packet ID of the application signals.Type: ApplicationFiled: July 25, 2023Publication date: November 16, 2023Inventors: Jan Van Doorn, Brian Field, Daniel Groustra, Mark Torluemke, James Hamilton Hall, JR.

Publication number: 20230336639Abstract: An announcement protocol may allow disparate, and previously incompatible, content delivery network caches to exchange information and cache content for one another. Announcement data may be stored by the respective caches, and used to determine whether a cache is able to service an incoming request. URL prefixes may be included in the announcements to identify the content, and longest-match lookups may be used to help determine a secondary option when a first cache determines that it lacks a requested content.Type: ApplicationFiled: June 20, 2023Publication date: October 19, 2023Inventors: Brian Field, Jan Van Doorn, Jim Hall

Publication number: 20230281666Abstract: Aspects of the disclosure relate to monitoring and using telemetry information in various ways. For example, a system that monitors telemetry information may include a user that gathers telemetry information of a device and transmits the information to a monitored room. A manager may join a monitored room and monitor the monitored room for particular types of telemetry information. In one example, a manager may determine whether a downstream device is experiencing a network problem, such as a low bitrate. A manager may also transmit commands to the player via the monitored room, which causes the downstream device to operate in accordance with the transmitted command. In one example, a manager may transmit a command that causes a player to decode a particular service.Type: ApplicationFiled: February 23, 2023Publication date: September 7, 2023Inventors: Brian Field, Jan Van Doorn, Joseph Kiok, Daniel Groustra, Mark Torluemke, Jim Hall, John Leddy

Patent number: 11210704Abstract: Aspects of the disclosure relate to monitoring and using telemetry information in various ways. For example, methods that monitor and use telemetry information may include receiving telemetry information relating to advertisements, whether the advertisement reporting is active, and/or whether thresholds associated with the output of advertisements have been satisfied. In some examples, telemetry information may be received via an application. In some examples, advertisments may be selected or generated for display based on analysis of the telemetry infomration. In some examples, commands may be transmitted to a device to initiate advertisement related reporting.Type: GrantFiled: October 9, 2020Date of Patent: December 28, 2021Assignee: Comcast Cable Communications, LLCInventors: Brian Field, Jan Van Doorn, Joseph Kiok, Daniel Groustra, Mark Torluemke, Jim Hall, John Leddy
