Patent number: 7100183Abstract: A system and method for transmitting and displaying information in a television distribution system (10), or the like, transmits information that is targeted to a viewer matching particular demographic data. The results of a viewer completed demographic survey are used to generate a database known as a bit mask (30) that is made up of the viewer's demographic data. The bit mask (30) is used to control the particular advertising or other related information that is received by each system viewer. In a first technique, the transmission signal carrying the program or advertisement displayed to all viewers is embedded with one or more codes. These codes are compared to the bit mask to determine whether the viewer fits the desired demographic profile, and should be provided with additional information. In a second technique, multiple ads for demographic selective receipt by each viewer are simultaneously transmitted, and are automatically selected for viewing, depending on the viewer's stored demographic data.Type: GrantFiled: February 1, 2001Date of Patent: August 29, 2006Assignee: Sedna Patent Services, LLCInventors: Gerard K.

Patent number: 7032238Abstract: A terminal is coupled to a video distribution network headend, and transmits upstream packets to the headend. Each upstream packet has a transmission power. The terminal receives a downstream packet from the headend, indicating a change in power. The terminal calculates an adjusted transmission power, based on the change in power specified in the downstream packet, and sets the transmission power of the upstream packets to the adjusted transmission power. The headend can be coupled to one or more terminals. The headend receives upstream packets from the terminal. The headend senses a received transmission power of each packet, and calculates a weighted average transmission power based on the received transmission powers. The headend calculates a change in transmission power based on the weighted average and a predetermined set point. The headend transmits a downstream packet to the terminal, indicating the change in power.Type: GrantFiled: July 18, 2001Date of Patent: April 18, 2006Assignee: Sedna Patent Services, LLCInventors: James Winton Parnell, Christopher Coonan, Richard L.

Patent number: 7027882Abstract: Methods and systems to enable simplified, compact implementations of profiling and other functions on STBs or other limited-resource computing platforms. For every television show transmitted from the server to the STB, the server also sends a classifying group identifier for the show. The STB then generates user profiles, ratings and/or recommendations, based on the group identifiers, simplifying the STB's processing tasks. Exception processing, special cases, or changes in group assignments or algorithms are handled at the server. The STB calculates viewing profiles based on recording statistics about content its user(s) view, based on the group identifiers. In another embodiment, the STB provides ratings and/or recommendations using group identifier information and related statistics. User privacy is maintained by stripping off and discarding personal information or averaging user profile information to erase or “blur” any suggestions of personal information.Type: GrantFiled: May 15, 2002Date of Patent: April 11, 2006Assignee: Sedna Patent Services, LLCInventors: Nathaniel Thurston, Devin Hosea
