An apparatus includes a network interface and a processor. The network interface receives event data that identifies a content ID and a message authentication code. The content ID identifies a content within a webcast or a virtual event. The processor generates a content hash, at least in part based on the content ID. The network interface transmits a content request and receives the content. The content request identifies the content hash and the message authentication code.

An apparatus includes a storage, a network interface, and a processor. The storage is to store content within a webcast or a virtual event. The network interface transmits a CDN token key and receives a client content request including a content hash and a message authentication code. The processor performs a decryption of the message authentication code, at least in part based on the CDN token key, and performs a reverse hash on the content hash to obtain a content ID that identifies the content. The network interface transmits the content, at least in part based on the content ID.

An apparatus includes a network interface that receives a CDN token key and transmits event data including a content ID that identifies content within a webcast or a virtual event. The apparatus also includes a processor that generates a message authentication code, at least in part based on the content ID and the CDN token key. The event data identifies the message authentication code, and the network interface transmits the content.

Embodiments of the present invention disclose a system for content triggered high-speed data service delivery independent of media delivery mechanisms. A backend system receives instructions from high-speed data customer indicating a selection of content triggered data service delivery; in response to receiving the instructions, enables content triggered data service delivery; (i) causes a gateway to cut-off HSD service or (ii) cuts-off supply to the gateway; causes a specified device connected to the gateway on its customer side to run a triggering content; and, in response to completion of running of the triggering content on the specified device, (i) causes the gateway to cut-on HSD service for the customer, or (ii) cutting on HSD service to the gateway and customer.

A communication control device that includes a synchronization detection unit that detects a synchronization timing from a synchronization signal and a transmission control unit that causes a communication unit to transmit a control signal., for changing a communication route of data to which a flag specified on the basis of the synchronization signal, to a network switch that performs relay between a reception device and a plurality of transmission devices that transmits the data to which the flag is added while changing the flag at the synchronization timing.
