A system is described for linking traditional media works, such as print and broadcast media for example, to a more interactive media conduit, such as the Internet. The system avoids the need to modify the media work in anyway. Instead, it employs a passive recognition system that uniquely identifies the specific work, such as a particular television or radio broadcast or printed commercial. The identification may be based in intra-work and / or extra-work information. Several different embodiments / environments are described. The best embodiment may depend, at least in part, on costs of hardware and communication. These costs can change over time. In one embodiment, all of the databases and computation are performed at the user's premises. In another embodiment, all of the databases and computation occur at remote sites that user premise equipment can query using uniquely identifying extra-work information, such as the time, place and station on which the work was broadcast. This second embodiment is most suitable for content that is published, e.g. magazines, newspapers, etc., or broadcasted, e.g. cable, satellite and terrestrial television and radio. Alternative embodiments, in which various operations are performed at both the user's premises and remote locations are also possible.

Internet access is provided through bandwidth available in broadcasted digital television signals, such as the digital television signals produced by terrestrial broadcast towers. Bandwidth is dynamically allocated or provisioned among clients, and is managed in part by the clients, thus providing dynamic, distributed management of spectrum allocation. Automatic provisioning may be applied among different terrestrial transmission towers, or different satellites, among transponders or channels on a given tower, or a given satellite, or among other forms of multiple broadcast origination points. The provisioning dynamically and automatically equalizes load among those multiple broadcast points. Principles of the present invention may also be applied to automatic provisioning of digital content among non-television broadcast sources, such as cellular telephone towers having available bandwidth, analog or digital radio broadcasts having available bandwidth, or satellite broadcast facilities, and / or dedicated broadcast towers or satellites operating in an allocated spectrum and limited to broadcasting requested digital content. In a satellite embodiment, provisioning may occur among multiple satellites as well as between transponders or time- or frequency-multiplexed channels provided by a single satellite.

A method and system for continually storing and cataloguing streams of broadcast content, allowing real-time searching and real-time results display of all catalogued video. A bank of video recording devices store and index all video content on any number of broadcast sources. This video is stored along with the associated program information such as program name, description, airdate and channel. A parallel process obtains the text of the program, either from the closed captioning data stream, or by using a speech-to-text system. Once the text is decoded, stored, and indexed, users can then perform searches against the text, and view matching video immediately along with its associated text and broadcast information. Users can retrieve program information by other methods, such as by airdate, originating station, program name and program description. An alerting mechanism scans all content in real-time and can be configured to notify users by various means upon the occurrence of a specified search criteria in the video stream. The system is preferably designed to be used on publicly available broadcast video content, but can also be used to catalog private video, such as conference speeches or audio-only content such as radio broadcasts.

A digital sampling playback doorbell system has two or more doorbell buttons and a central unit with solid state memory storage for multiple digitally sampled sound files. User assignment means are provided for assigning a particular sound file to a particular doorbell button. The digital sampling playback doorbell has computer interface of RS-232, or USB, or infrared wireless connection type and relies on computer installed software to download digitally sampled sound files stored in the computer hard drive to the memory of the digital sampling playback doorbell system central unit. The digitally sampled sound files stored in the computer hard drive are obtained by accessing a web site through the Internet or capturing sound through an audio computer connection to a microphone, CD player, radio broadcast or mass music storage device using software resident in the computer. Alternatively, an IPOD can be used as a source for sounds that can be transferred or sent to play on the doorbell. Such sound transfer can take place via a blue tooth communication link, or by a docking station that resides on the doorbell. Taking advantage of the intelligence contained within the IPOD, one can then select sounds or files that have been previously converted by either the IPOD or the computer that the IPOD was previously attached to, and send them to the doorbell.

A dual-port IBOC® antenna provides omnidirectional radiation of orthogonal, circularly polarized analog (FM) and digital (OFDM) signals using quadruple coplanar square loops driven from a hybrid having balanced outputs. The loops are arranged in a tiled square, with proximal sides functioning as further stripline hybrids to cancel cross coupling between the loops. Each loop quad is reflector-backed and emits a directional signal; multiple loop quads oriented radially form an omni bay. Vertical spacing between bays includes a minimum position for mutual coupling, while symmetry establishes uniform input impedance on the hybrid input ports. Tuning barbs on the loops fine tune frequency response. Bandwidth is wide, so that a single antenna can radiate multiple FM analog and hybrid IBOC® channels over the VHF FM radio broadcast band.
