摘要:
A method and apparatus for receiving logical address links in advance of a television program and combining such links with those that may be received in real-time during a television broadcast are provided. According to one aspect of the present invention, content associated with a television (TV) program may be automatically displayed by a client system, such as an Internet terminal or a computer equipped with a TV tuner. Prior to broadcast of a TV program, TV listing information is stored in the client system. The TV listing information includes one or more batch mode logical addresses, e.g., Uniform Resource Locators (URLs), that identify content, such as Internet content. The client system alerts the viewer of the existence of an active logical address associated with the current TV program by providing a visual indication. After the visual indication has been selected by the viewer, the client system displays the content identified by the logical address. Additionally, one or more real-time logical addresses may be received by the client system embedded in a video signal associated with the TV program. The real-time logical addresses may be embedded in either a text service channel (e.g., T1, T2, T3, T4) or a captioning service channel (e.g., CC1, CC2, CC3, CC4) of the vertical blanking interval (VBI) of the video signal. When both real-time logical addresses and batch mode logical addresses are associated with a TV program, the client system determines which to bring to the attention of the user of the client system based upon a set of predefined rules. Importantly, features of the present invention are applicable to many broadcast television (TV) systems including National Television Standards Committee (NTSC), Phase Alternate Lines (PAL), and Sequential Couleur Avec Memoire (SECAM) as well as the proposed High Definition Television (HDTV) standard.
摘要:
A system and method for ensuring accurate reception of digitally encoded files that are transmitted in non-real time from a distribution station to a plurality of receiving stations, e.g. cable headends. Each file is divided into a plurality of data packets, with the packets being transmitted via satellite to the headends. Each headend determines which packets are in error (i.e. missing or jumbled) and need to be re-transmitted to the headend from the distribution station. After such a determination, each headend communicates a request over a land-link, e.g. telephone line or internet, to the distribution station requesting re-transmission of the packets in error. The distribution station then re-transmits these particular packets either via the land-link or the satellite. Re-transmission in non-real time via the land-link allows the headend to simultaneously receive packets via satellite and land-link so as to reduce the time taken to transmit files from the distribution station to the headends. The different land-links coupling the distribution station to each receiving station allow different data packets to simultaneously be re-transmitted to different receiving stations.

Methods and apparatus for encouraging viewers to pay attention to commercials by incentivizing viewers to watch. Viewers are notified that they can receive rewards for answering one or more questions during or at the conclusion of the commercial. To verify that the viewer paid attention to the commercial, the answer to the question may be based on the content of the commercial. A sponsor might ask, for example, that the viewer identify the name of the sponsor or the color of an announcer's shirt. A correct answer indicates that the viewer watched the commercial, and the viewer is therefore entitled to some reward. For example, viewers who watch the commercial may be entered in a prize drawing, or may receive prize points, such as frequent-flier miles. In other embodiments, viewers may verify that they watched a given program by selecting an icon or pressing a button on a remote control.

Subject matter includes methods of using conventional set-top boxes that receive streaming video modulated on coaxial cable rather than over an IP-based LAN as nodes in a media network. In one implementation, an exemplary adapter is used to integrate a conventional set-top box into a media network. In one implementation, an exemplary filter is used to reserve frequencies for communications between a conventional set-top box and a hub and to prevent communications from leaving a media network. In one implementation, an exemplary content protection method provides a way of encrypting program content on the media network in a manner that a conventional set-top box can decode.

Program boundaries are determined through viewing behavior. More specifically, edge and/or commercial boundaries of programs may be determined by monitoring viewing behavior of different video segments using forward and backward correlations between video segments. In a described implementation, a video portion is divided into segments. To monitor the viewing of the video portion, whether each particular segment is played by a viewer (as compared to being unviewed or viewed in an accelerated manner) is tracked for a number of different viewers. For each segment, correlations with previous and subsequent segments are calculated based on viewership. The segments may then be categorized. A segment that is strongly correlated with subsequent segments but not previous segments is categorized as a starting segment. A segment that is strongly correlated with previous segments but not subsequent segments is categorized as an ending segment. Middle and island segments may also be categorized.

Displaying content associated with a television program using logical addresses identifying the content. Content associated with the television program is automatically displayed by a set top box. Before the broadcast of a program, television listing information, such as EPG data, is stored at the set top box. The listing information includes batch mode logical addresses or links. During the program, a viewer is notified about the link, enabling the content to be accessed and displayed concurrently with the program. In addition, real-time logical addresses or links, which are embedded in the program, may be extracted and displayed to the viewer. If both the real-time and batch mode links are available, a determination is made according to pre-defined rules regarding which link is brought to the attention of the viewer. In this manner, real-time links can be supplied with the broadcast to supplement or replace the batch mode links.

Subject matter includes a reprogrammer for roving remote controllers that are capable of being used in multiple locations with different devices to be controlled at each location. An exemplary roving remote controller changes control code sets to operate whatever devices are present in a particular room. In one implementation, an exemplary multimedia system has reprogrammers for one or more roving remote controllers that adapt to their setting. When a remote controller is moved from a first room to a second room, the program content being controlled in the first room is automatically transferred to the second room.

In interactive television, a broadcaster may broadcast triggers to a great many receiver units prompting the receiver units to attempt to send requests to a single destination on the Internet at roughly the same time. Such a large number of simultaneous requests can give rise to throughput problems and server overload. A receiver unit in accordance with the invention, rather than immediately attempting to send a request, waits a period of time (for example, a random period) before sending the request so as not to overload the server. In one embodiment, a trigger is received on an interactive television receiver unit prompting the viewer to select an icon. If the viewer selects the icon, then a browser in the receiver unit retrieves a web page on the Internet identified by a URL in the trigger. The web page includes an indication of a destination, scheduling information, and a form area. The viewer enters user information in association with the form area. The browser captures that user information, incorporates it into a request, and then stores the request in a queue along with the scheduling information. The browser periodically checks the scheduling information in the queue and determines from the scheduling information if it is time to send the request. When the browser determines the time has come to send a request in the queue, the browser retrieves the request and sends it to the destination. The browser may then receive a return response and display it.
