Abstract: A technique for the blocking of individual programs and/or portions of programs transmitted in a source signal, e.g., a cable television signal. In particular, individual programs and/or portions of programs within a class of programs are blocked, while allowing for the viewing of certain other programs even within the same programming class. The transmitted source signal contains individual programs having a transparent program identifier and/or transparent content identifier associated with individual programs in the source signal transmission. As the source signal enters, e.g., a particular subscriber location, the source signal is monitored in accordance with a program viewing profile defined by the subscriber. That is, particular ones of the programs and/or portion thereof available in the source signal transmission supplied to the subscriber can either be unblocked, i.e., viewable, or blocked, i.e., unviewable, at the discretion of the subscriber.

Abstract: Digital information is encoded in the video portion of a television signal such that "n" (n is an integer) bits of the digital information are carried by each successive frame in a group of frames. The digital information is encoded by modulating a carrier signal, using, for example, either amplitude shift keying (ASK) or frequency shift keying (FSK), and the modulated carrier is then added to the video signal selectively, only in portions of the television program that (a) are not likely to be perceptible by a viewer, and (b) are of sufficient intensity to transmit the data. The video signal including the encoded digital data, may be transmitted, in real time, to a television receiver, or recorded for later playback.

Abstract: Techniques for employing a television set and a television set controller as the control interface for devices which themselves do not have display capability and for services provided via the telephone network. The techniques involve control apparatus which is connected to the telephone network and a television set and is responsive to inputs from a hand-held controller for the television set. The control apparatus outputs a screen which contains control selections to the television set and the user employs the controller to make a selection. The control apparatus then performs the control function specified by the selection. One application is a telephone messaging system: integral with the control apparatus is a system which can answer calls and store voice messages, fax messages, character-string messages, and script messages. The control apparatus plays the voice messages on the television set and provide screens to the television set which display the fax and character-string messages.

Abstract: A wireless Local Area Network (LAN) includes a repeater which a) synchronizes interface adapters for portable end-user devices and b) retransmits data signals received which retimes and retransmits data signals received from these end-user devices that gain, one at a time, the exclusive right to transmit those signals during a given transmission time subframe by contending for access to the LAN resources that are auctioned off to permit LAN resource utilization that is independent of traffic load and that is implemented in a near collision-free environment.
