Abstract: A broadcast receiver includes a communicator configured to receive broadcast data including metadata associated with an application and a controller configured to obtain a comparison result by comparing a reference hash with a metadata hash generated based on the metadata, authenticate the metadata based on the comparison result, and launch the application based on a result of the authentication.

Abstract: A method of controlling implementation of an application in a device includes obtaining identification information of one or more applications to perform rendering of media data in the device, displaying the obtained identification information on a screen of the device, and executing one application according to receipt, from a user, of an execution request of the application from among the one or more applications.

Abstract: An apparatus and method for receiving a broadcast stream is provided. The apparatus is configured to receive key information and additional information through the broadcast stream, select one of a plurality of predetermined functions based on the additional information, and perform the selected function in response to a control signal identified by the key information. The additional information may include link information such as a URL or telephone number, and the function may be selected based on a type of the link information. In some embodiments, the link information may be extracted from audio-visual data of a selected programme, using optical character recognition. The apparatus may connect to a secondary device to transmit information to the secondary device, and may receive information relating to the selected programme from the secondary device.

Abstract: A method of enabling transmission of a data service from a content server to a terminal using a data channel in a system in which at least part of the data service is transmitted to the terminal using a broadcast channel, the method including: receiving, using the broadcast channel, first data comprising part of the data service; processing the first data using a signature-generating algorithm to derive first signature data; transmitting the first signature data using the data channel to the content server; validating the first signature data by comparing said first signature data with a signature derived by processing data comprising part of the data service using a corresponding signature-generating algorithm; and enabling the terminal to access the data service using the data channel dependent on validation of the first signature data.

Abstract: A broadcasting receiving apparatus capable of communicating with a secondary device includes a receiving module configured to receive application information relating to a selected program; and a control module configured to receive a control command from a control device, wherein the control module, in response to a predetermined control signal, controls the secondary device to execute an application identified by the application information, when the secondary device is registered in order to communicate with the broadcast receiving apparatus.

Abstract: A system for blasting lateral holes in the formation around a well bore, the well bore containing production casing and production tubing inside the producting casing. The system includes: a coiled tubing system including a first pump for pumping under pressure cutting fluid; coiled tubing for inserting into the production tubing; a flexible hose having a first end attached to the bottom end of the coiled tubing; a jetting nozzle attached to a second end of the flexible hose; and a deflection shoe adapted for attaching to the bottom of the production tubing. The system further comprises a centering system for centering the coiled tubing within the production tubing; a fluid transport system comprising a second pump and tubing adapted for pumping circulating fluid through the production casing; and a flow-back system comprising tubing adapted for receiving spent cutting fluid out of the production casing.
