A system and method of adding hyperlinked information to a television broadcast in which an interactive content icon is used. The broadcast material is analyzed and one or more regions within a frame are identified. Additional information can be associated with a region, and can be transmitted in encoded form, using timing information to identify the frame with which the information is associated. The system comprising a video source and an encoder that produces a transport stream in communication with the video source, an annotation source, a data packet stream generator that produces encoded annotation data packets in communication with the annotation source and the encoder, and a multiplexer system in communication with the encoder and the data packet stream generator. The encoder provides timestamp information to the data packet stream generator and the data packet stream generator synchronizes annotation data from the annotation source with a video signal from the video source in response to the timestamp information. The multiplexer generates a digital broadcast signal that includes an augmented transport stream from the transport stream and the encoded data packets. A receiver displays the annotation information associated with the video signal in response to a viewer request on a frame by frame basis. A viewer can respond interactively to the material, including performing commercial transactions, by using a backchannel that is provided for interactive communication. The interactive content icon can be used to inform a viewer of the presence of hyperlinked information, for teaching the viewer how to use the system, and for informing the viewer about the hyperlinked information.

In one embodiment of the invention, a system and method for receiving and correcting content is provided. A receiver receives a plurality of transmission with embedded content key identifiers. Data packets for which the receiver has a corresponding authentication key are authenticated. Non-successful authentications, or data packets without a corresponding authentication key, are ignored by the receiver. The receiver checks if the content is encrypted. If so, the content may also be decrypted using content decryption keys stored within the receiver. Authentication keys and decryption keys may be updated via secure transmissions. The receiver status is monitored for incomplete and / or corrupted content receipt. The failed content may be retransmitted to the receiver over radio transmitters. Failed content may also be supplied to the receiver via the backchannel. Retransmission of the content may be performed according to a content delivery schedule.

A direct content delivery method, intended for directly delivering regular audiovisual and marketing content to consumers, includes regularly providing a delivery component having audiovisual content, marketing content, and backchannel connection information. The delivery component may be directly physically or directly electronically distributed to consumers. Consumers view the audiovisual content but may not avoid the marketing content. Consumers are drawn to the high quality audiovisual content, which may be episodic in nature. A backchannel connection arrangement, correlated to the backchannel connection information, implements a two-way direct communication path.

A Power Line Communications (PLC) device includes a processing module, memory, a Wireless Local Area Network interface (WLAN I / F), and a PLC communication interface (PLC I / F). When operating as a client device, the PLC device establishes communications with a premises communication device via the PLC I / F, requests WLAN service from the premises communication device via the PLC I / F, receives WLAN access credentials from the premises communication device via the PLC I / F, and accesses a WLAN via the WLAN I / F using the WLAN access credentials. The PLC device communicates with a client device via the PLC I / F, receives a WLAN service request from the client device via the PLC I / F, validates the client device for WLAN service, and transmits WLAN access credentials to the client device via the PLC I / F. The PLC device may also support backchannel operations such as financial transactions, key exchanges, encryption support, all via the PLC I / F.

Described are communication systems that convey differential and common-mode signals over the same differential channel. Noise-tolerant communication schemes use low-amplitude common-mode signals thatare easily rejected by differential receivers, thus allowing for very high differential data rates. Some embodiments employ the common-mode signals to transmit backchannel signals for adjusting the characteristics of the differential transmitter. Backchannel control signals are effectively conveyed even if the forward channel transmitter is so maladjusted that the received differential data is unrecognizable. Systems in accordance with the above-described embodiments obtain these advantages without additional pins or communications channels, and are compatible with both AC-coupled and DC-coupled communications channels. Data coding schemes and corresponding data recovery circuits eliminate the need for complex, high-speed CDR circuits.

Streaming content may be delivered through a combination of broadcast and a backchannel. Related apparatus and methods for receiving and distributing streaming content are described. A receiving device may receive a packet of information in the form of a broadcast signal from a broadcast source. The packet of information may contain one or more streamlets and a table of contents associated with the streamlets. A desired streamlet may be selected from the packet of information and presented with a display. A remainder of a data stream associated with the streamlet may be requested and received from via a backchannel while the desired streamlet is being presented. The remaining data stream may then be presented with the display.

A voice processing system comprises a processing device that processes and receives a stream of voice input as a user is speaking. A software program executes program steps for determining a predetermined pattern of speech and silence during processing of stream of voice input so as to play or present the predetermined backchannel response to the user. A method provides an audible backchannel response between the voice processing system and the user, while the user is speaking, in particular, recording a message. The method includes monitoring the message to determine a predetermined pattern of speech and silence based on timing between the speech and silence periods. Then, the method produces the audible backchannel response based on the predetermined pattern. An audible user interface includes a speech processor that processes or classifies an audio message in the telecommunication device as speech and silence frame while a calling party is speaking, in particular, recording the audio message to a called party. A control circuitry cooperates with the speech processor and responds to a predetermined pattern of the speech and silence segments so as to play the preset backchannel response in audible form to the calling party.
