1. A method comprising: constraining an executable environment in a security sandbox of a mobile device; executing a sandboxed application in the executable environment of the mobile device capable of bypassing at least one access control of the security sandbox; associating the mobile device with a television based on: executing a sandbox-reachable service on the television; automatically announcing, through the television, the sandbox-reachable service to a discovery module executing at least one of: on a pairing server external to the mobile device and as part of an extension of the security sandbox executing on the mobile device; identifying the sandbox-reachable service offered through the television based on receiving, through the discovery module, the automatic announcement to enable the sandboxed application of the mobile device reach the sandbox-reachable service by communicating an identification data of the television via the sandbox-reachable service when a shared computer network is determined to be commonly associated with the mobile device and the television; and establishing bidirectional communication between the mobile device and the television based on the sandboxed application reaching the sandbox-reachable service; generating, through at least one of: the television and the mobile device, fingerprint data from characteristic features of media data on the television; matching primary data generated from the fingerprint data with targeted data using a relevancy-matching server based on a relevancy factor, the matching comprising locating in a storage at least one of a matching item and a related item based on the relevancy factor; locating in the storage at least one of the targeted data, a reference to the targeted data and a metadata of the targeted data using the relevancy-matching server; and processing in the sandboxed application an embedded object from the relevancy-matching server; rendering the primary data available across the sandbox-reachable service and the sandboxed application based on the bidirectional communication between the mobile device and the television; and executing the embedded object through the sandboxed application to cause rendering of the targeted data therethrough in accordance with the availability of the primary data across the sandbox-reachable service and the sandboxed application, and the matching thereof using the relevancy matching server.
