A sink device is bi-directionally communicably connected to the source device. The sink device includes a first memory, and a controller. Stored in the first memory is a plurality of pieces of audio format information including information representing an audio format that the sink device can process. The controller selects, from among the plurality of pieces of audio format information stored in the first memory, one piece of audio format information corresponding to receiver format information representing an audio format that a receiver device connected to the sink device can process. The controller then outputs the selected audio format information to the source device.

Techniques described herein automatically identify, in a multimedia content, an advertiser from which an advertisement in the multimedia content originates and/or a brand to which the advertisement pertains.

A method and apparatus for brokering the enablement of the communication of encrypted media programs from a plurality of independent broadcasters to a plurality of receivers is disclosed. The system makes use of a pairing key for each provided service, which is differently encrypted by a pairing server and by the broadcaster providing the service. The encrypted versions of the pairing key are decrypted in a first receiver module using information known to the pairing service but not the broadcaster and in a second receiver module using information known to the broadcaster. The pairing key is used to cryptographically bind the first and second receiver modules.

A method for controlling multiple devices using a virtual device that may be displayed on a screen. The method may include providing the information for the virtual device from a set-top box to the screen. The method may also include using a control device to scroll around the virtual device and make a selection fro the options provided by the virtual device. Additionally, the buttons on the control device may not correspond to the functionality associated with the virtual buttons on the virtual device.

The present disclosure discloses a data transmission method and apparatus. User equipment (UE) measures and transmits a transmission delay to a group communication service application server (GCS AS), or the GCS AS itself determines a transmission delay, so that the GCS AS may determine, according to the transmission delay, a time of sending a packet on a multicast path or a unicast path. Therefore, a problem of out of order of packets or a loss of a packet due to a transmission delay is resolved, and continuity of a communication service is maintained.

A display apparatus and a control method thereof are provided. The display apparatus includes: a signal receiver configured to receive an image signal; a signal processor configured to process the received image signal; a display configured to display an image based on the processed image signal; a storage; a user input receiver configured to receive a user input; and a processor configured to display, on the display, at least one candidate profile from among a plurality of candidate profiles, each of which includes different setting information for a plurality of setting items, to select one from among the displayed at least one candidate profile according to the received user input, and to store in the storage in response to the selecting, the setting information for the plurality of setting items includes in the selected candidate profile. Accordingly, the display apparatus may simplify or automate an initial setting process.
