An interactive television program guide system is provided. An interactive television program guide provides users with an opportunity to select programs for recording on a remote media server. Programs may also be recorded on a local media server. The program guide provides users with VCR-like control over programs that are played back from the media servers and over real-time cached copies of the programs. The program guide also provides users with an opportunity to designate gift recipients for whom programs may be recorded.

Client-server based interactive television program guide system with remote server recording

Methods and systems that provide enhanced personal video recorder (“PVR”) and interactive television program guide (“IPG”) functionality are provided. An interactive television application (“application”) may be implemented to provide such functionality. The application may be used to display a list of PVR recordings, to schedule recordings to a PVR, to configure recordings, to view a list of scheduled recordings, to configure recording settings, or to select delete priority settings for recordings. The application may integrate pay-per-view and PVR functionality. The application may send user notifications for changes that are to be made to the recording content of a PVR. Live programming may be buffered by the application using a straight buffers that are created for each new program. Parallel buffers for concurrent programs may be implemented using multiple tuners. Straight buffers may be used in managing or controlling the flow of programming. Television content may be automatically paused when a user is engaged in using the application. Multiple IPGs for different users of a PVR may be implemented. Other PVR related features are also provided.

Systems and methods for interactive program guides with personal video recording features

A client-server interactive television program guide system is provided. An interactive television program guide client is implemented on user television equipment. The interactive television program guide provides users with an opportunity to define expressions that are processed by the program guide server. The program guide server may provide program guide data, schedules reminders, schedules program recordings, and parentally locks programs based on the expressions. Users' viewing histories may be tracked. The program guide server may analyze the viewing histories and generates viewing recommendations, targets advertising, and collects program ratings information based on the viewing histories.

Active pixel sensor with intra-pixel charge transfer

A unit is attached to a refrigeration appliance, such as a freezer, or refrigerator, to alert the user of a sensed condition within the appliance that food spoilage may occur. The unit can monitor temperature within the compartment and determine how long until food spoilage occurs. The unit also can alert a user, monitoring service, or call a repairperson. The unit may be retrofit into existing appliances.

Refrigeration monitor unit

A home-bus-information display system arranged such that the control status of each of a plurality of home apparatus can be monitored via home bus-lines and additively displayed over a video program on the picture screen of a television receiver to allow a viewer to monitor the control status of each of other home electric apparatus, a security system and so on in a centralized-control fashion.

Home-bus-information system

Methods and apparatuses for displaying broadcast history information of a plurality of episodes of a program on an audio-visual system, which enable a viewer to select a program for which the history information of each episode will be stored. In response to the viewer's selection, the audio-visual system stores the history information for the episodes of the selected program that has been received by the audio-visual system. The audio-visual system can display the history information when the viewer watches the current episode of the program in a future time.

A 1-in optical format frame-interline-transfer charge-coupled-device (FIT-CCD) image sensor with 2 million pixels and an aspect ratio of 16(H):9(V) has been developed for HDTV cameras. The effective number of pixels is 1920(H)*1036(V). In order to decrease the smear level, achieve uniform charge handling capability for the vertical CCD, and eliminate defects that appear as vertical stripes in the image of the device, aluminum wire was put onto the vertical transfer gate to decrease the resistance in the transfer gate and a dual-channel two-phase CCD was utilized for the horizontal shift register operated by a 37.125-MHz clock. As a result, this image sensor has a dynamic range of 72 dB and a sensitivity of 75 nA/lx for light with a color temperature of 2856 K. Smear is reduced to -100 dB by using the FIT-CCD image sensor structure. The horizontal limit is 1000 TV lines. In addition, image lag is negligibly small and below the sensitivity of the measurement instrument. >

A three-dimensional video signal generator has a high-definition video signal source for generating left and right high-definition video signals having, as left and right video signals, video signals in respective effective scanning periods of odd-numbered and even-numbered field signals of a interlaced-scanning high-definition video signal composed of 1125 scanning lines and having an interlace factor of 2:1. The left and right video signals in the respective effective scanning periods of the left and right high-definition video signals supplied from said high-definition video signal source are vertically compressed in time with a compression ratio of 11:5. The compressed left and right video signals in the odd-numbered and even-numbered fields are combined into a three-dimensional video signal disposed in each of effective scanning periods of odd-numbered and even-numbered field signals of one high-definition video signal, with a pseudo vertical blanking period of a given time duration inserted between the compressed left and right video signals such that the time interval of the compressed left and right video signals becomes a 1/2 field period.

Three-dimensional video signal generator and three-dimensional video display apparatus

A ghost cancelling system for eliminating a ghost by using a ghost cancelling signal formed from an input video signal including the ghost and adding the ghost cancelling signal to the input video signal. In this ghost cancelling system, the divergence of the ghost cancelling circuit is avoided during the transient time of the channel selection or during the ghost cancelling process, and when there is the possibility that the ghost cancelling circuit diverges, the circuit is firstly made operable as a feed-forward type circuit for a predetermined period and thereafter made operable as a feedback type circuit.
