Systems, methods, and devices of the various embodiments disclosed herein may provide a protocol and architecture for decentralization of content delivery. Various embodiments may provide a client based method for content delivery from content delivery networks (CDNs) via tiered caches of content hosted by Internet Service Providers (ISPs). In various embodiments, content delivery protocol (CDP) messages may enable clients to discover local cache network topologies and request content from a CDN based on a discovered local cache network topology. In various embodiments, security may be provided for the content delivery by the use of key encryption and/or file hashing.

The present application discloses techniques for playback of live broadcast content. The techniques comprise receiving a request of playing live broadcast content from a client computing device, wherein the request comprises information indicating a first address associated with the live broadcast content, and the request further comprises a playback time parameter indicating a playback time length; generating a second address based on a current system time parameter, the first address, and the playback time parameter; obtaining live broadcast content based on the second address and transmitting the live broadcast content to the client computing device.

A receiving device, a receiving method, a transmitting device, and a transmitting method. The receiving device acquires a digital broadcast signal that includes audio-video (AV) content and location information, the location information indicating a source from which application control information for controlling an operation of an application executed in conjunction with a progressing timing of the AV content is obtainable, acquires the application control information from the source indicated by the location information, the application control information including an application ID and a uniform resource locator (URL), obtains, from the URL included in the acquired application control information, control information during a polling period that is defined in accordance with an attribute specified in the acquired application control information, and controls the operation of the application based on the acquired application control information and the obtained control information.

Systems and methods for retrieving regional content via remote access point servers are disclosed. In one embodiment, the disclosure relates to a network system for content retrieval from remote network regions. The network system may comprise a first device. The first device may be configured to receive a request for content. The content may be on one or more content servers located in a remote network region. The first device may be further configured to at least one of forwarding the request, via tunneling, to a destination access point server located in proximity to the one or more content servers and receiving the content from the destination access point server, obtaining the content from a cache of the first device.

Systems and methods are provided for enhanced ship-based network connectivity using a content delivery network (CDN) edge server. An example method includes receiving user requests from user devices in wireless communication with a system, with the user requests being associated with applications executing on the user devices. An operating status associated with a satellite communication system is determined, the operation status being indicative of the satellite communication system having bandwidth and/or connectivity to route the user requests via a satellite network. Based on the operating status being negative, a first subset of the user requests is queued for transmission. A second subset of the user requests are responded to using an edge cache. Based on the operating status being positive, the user requests are transmitted via the satellite network to a shore-based system, the shore-based system routing the user requests to web applications associated with different functionality.
