Abstract: A novel multiple channel architecture is designed to allow targeted advertising directed to television terminals connected to an operations center or a cable headend. Advertisements are displayed during commercial breaks in the television programs. Such advertisements may be broadcast on the same channel as the television program. In addition, feeder channels may carry alternate advertising that may be better suited for certain viewing audiences. The operations center or the cable headend generate a group assignment plan that assigns the television terminals to groups, based on factors such as area of dominant influence, household income and other demographic data, and programs watched data gathered by the television terminals. A switching plan is then generated that instructs the television terminals to remain with the program channel or to switch to one of the alternate feeder channels during the program breaks.

Abstract: An open cable set-top box diagnosing system in which a point of deployment (POD), separated from a main circuit unit, having a newly defined interface is used to check an operation state of an open cable set-top box, transmits the checked state to a predetermined server, according to which the operation state of the open cable set-top box is diagnosed. The open cable set-top box diagnosing system includes an open cable set-top box for checking its own operation state by using a diagnosis resource by a communication protocol between a point of deployment (POD) separated from the main circuit unit and the main circuit, and a head end for providing a service corresponding to a request signal received from the open cable set-top box or providing a broadcast program to the open cable set-top box, and checking the operation state of the open cable set-top box.

Abstract: Dynamic rate control can be implemented in a television-based entertainment environment when forwarding coded data. Real-time information flows are encoded, transcoded, compressed, etc. into data streams that may be forwarded to other components within an apparatus or to other apparatuses across a network. In a described implementation, a bitcount accumulation of a data stream is monitored in multiple overlapping windows. The data stream is compared to a data limit in each window of the multiple overlapping windows to determine whether an expected bitcount accumulation has been exceeded. The data stream is modified responsive to the comparison(s). For example, if the bitcount accumulations in each window exceed the expected bit accumulations at the corresponding relative positions of each window, then the bit rate of the data stream can be modified by reducing bit rate consumption.

Abstract: The present invention provides a method for object retransmission in an asynchronous environment without a continuous network connection in a digital media distributor (DMD) system. The method includes receiving objects in a receiver from a central site, generating a response document in the receiver, and sending the response document asynchronously to the central site. The received response documents are then utilized in the central site to determine which object to retransmit to the receiver. In another aspect of the present invention, the central site manages the inventory of objects in the receiver by instructing the receiver to delete objects not needed.

Abstract: The invention recommends television programs that are similar to shows identified by a user by computing a similarity metric between programs both in a user-specified selected set and in an identified time interval. The selected set comprises programs currently of interest to the user, for allowing the user or viewer to easily select one or more programs of interest. The similarity metric is a sum of weighted scores for each matching attribute between programs in the selected set and programs in the identified time interval. Shows that are actually selected for viewing are observed and the weightings, wi, assigned to each matching program attribute are adjusted, so that over time, the similarity metric, SM, more accurately reflects the viewer's idea of “similar shows.

Abstract: A system for displaying an electronic program guide (EPG) to a viewer. The system includes displaying one or more data slices representative of broadcast programming to a viewer. In response to input from the viewer, the displayed number of data slices is increased, for example, from one slice to two slices. In browser mode the viewer can scroll through multiple EPG data slices without selecting to view full mode EPG, while in full mode the EPG can expand from a single column of data slices to multiple columns of data slices based upon viewer selections. The EPGs of the present invention can display programming that a viewer is more likely to watch at a particular time than other programming. A data slice representing the predicted programming can be inserted into the EPG so that the viewer can identify programming that is likely to be of interest.
