Coalition network identification using iterative process

One or more computing devices, systems, and/or methods are provided. Event information associated with a plurality of events may be identified. The plurality of events may be associated with first entities corresponding to a first entity type and second entities associated with a second entity type. A first network profile associated with the first entities and the second entities may be generated based upon the event information. An iterative process may be performed to identify a coalition network associated with fraudulent activity. The iterative process may include analyzing the first network profile to identify a first set of entities, of the first entities, that are related to an entity of the second entities, and/or analyzing the first network profile to identify a second set of entities, of the second entities, that are related to the first set of entities. Multiple iterations may be performed to identify the coalition network.

Systems and methods for automatically generating top level index files
11716371 · 2023-08-01 · ·

Systems and methods for automatically generating top level index files for use in adaptive bitrate streaming in accordance with embodiments of the invention are disclosed. One embodiment of the method of the invention includes receiving a request from a playback device at a playback server, where the request identifies a piece of content, retrieving a list of assets associated with the identified piece of content using the playback server, filtering the list of assets using at least one predetermined criterion using the playback server, generating a top level index file describing each asset in the filtered list of assets using the playback server, and sending the top level index file to the playback device using the playback server.

PROGRAM PLAYING METHOD AND APPARATUS
20230024313 · 2023-01-26 ·

In the field of communications technologies, disclosed are a program playing method and apparatus, to resolve problems of relatively high costs of an internet protocol television (IPTV) operator and relatively high costs for subscribing to and maintaining an IPTV service by a user. In the method, a communications device receives a program playing request message sent by using a first transmission protocol. The communications device determines a corresponding target program channel based on a media file identifier included in the program playing request message, and may send a data stream request message to an IPTV platform by using a second transmission protocol. The communications device may send, by using the first transmission protocol, a received data stream to a playing device for play.

Cloud Queue Tombstone
20230231901 · 2023-07-20 ·

Example techniques relate to cloud queue tombstones. An example implementation may involve a computing system receiving instructions to remove a particular media item from a playback queue. Based on the instructions, the computing system removes the particular media item from the playback queue and adds, to the playback queue, a tombstone indicator indicating that the particular media item has been removed from the playback queue. The computing system receives, from the media playback system, a request for a window of one or more media items from the playback queue. Based on the request, the computing system sends, to the media playback system, data representing a particular window of media items from the playback queue, wherein the particular window includes the tombstone indicator. The computing system detects a given tombstone removal trigger from among multiple tombstone removal triggers and based on the detecting, removes the tombstone indicator from the playback queue.
