Abstract: A system provides a personalized visual channel for a user based on visual input received from other users, while the user him/herself also provides visual information. The users are connected via a network (14), and the personalized visual channel may be generated in a server entity (15). For controlling the content of the channel relationship information is maintained that is indicative of a relational distance between the user and other users. The channel shows a wheel-like visual structure (45) that has a home element (40) visually representing a home location of the user, and other user elements (41, 42, 43, 44). The user elements are positioned at a distance from the home element in dependence on the relationship information. The user controls the structure via a local remote control unit having specific visual control functions.

Abstract: A system method and apparatus for selectively recording on a VCR cassette, those news items of interest to a particular subscriber includes selecting video news items in accordance with previously entered user selected key word criteria. An advance data stream representing the text of each upcoming broadcast news item is provided in advance of the video broadcast of that news item. The advance data stream is searched for a match with any of the key word criteria previously entered by the subscriber. If a match between the stored user selected key word criteria and the advance data stream is found, the subscriber's VCR is enabled at the appropriate later time to record the desired news item. The VCR cassette contains those news items of interest to the particular subscriber, which the subscriber may watch at, any convenient later time.

Abstract: An information handling system controls a signal processing device by providing a control signal to the signal processing device. The control signal may be transmitted to the signal processing device as an infrared or R/F signal that is received and decoded by the signal processing device. The signal processing device is capable of receiving and processing an input signal, and is further capable of providing an output signal to the information handling system. In response to the control signal, the signal processing device encodes data onto the output signal provided to the information handling system, and the information handling system is capable of decoding the data from the output signal. The data encoded onto the output signal may include status information from the signal processing device, including the status of execution of the control signal. In one embodiment, the output signal is a video signal, such as the case where the signal processor is a VCR or the like, and the data is encoded onto a vertical blanking interval of the video signal such that state information is communicated from the signal processor to the information handling system via the vertical blanking interval.

Abstract: A process for associating and delivering data with a video signal includes digitizing an analog data signal. The digitized data is then compressed and transcoded into a format compatible with a video source signal. The data is then inserted into unused video lines of the video source signal outside the vertical and horizontal blanking internet. The encoded video source signal is transmitted to a decoder where the inserted data is separated from the video source signal. The inserted data is then converted to its original form, and either visually displayed or audibly delivered to an end user. The invention can be used to associate and deliver audio narrative description with a video signal for the benefit of the visually impaired.

Abstract: Designed for use with widescreen TVs or high-end TVs with a mode for accommodating anamorphic programs, an EPG client is equipped with an electronic program guide (EPG) and a letterbox-to-anamorphic converter. The EPG client evaluates EPG data to determine whether programs are in the letterbox format. When a letterboxed program is selected for viewing, the EPG client vertically stretches the program by a ratio of M/N, where M>N (e.g., 4/3), to convert the program from the letterbox format to an anamorphic format prior to delivery to the television. The converted anamorphic program is output to the television, where it is horizontally expanded to fit the screen.

Abstract: In a bilingual television signal processor which is capable of automatically controlling a bandpass filter for detecting a pilot signal included in a bilingual signal received in a television receiver having a bilingual function without an external adjustment, an improvement including a microcomputer for outputting an on-screen display message indicating a bilingual broadcasting and scanning the locked information of the pilot signal outputted from the PLL detector in a predetermined voltage range and step and outputting a corresponding pulse width modulated (PWM) signal, and a digital/analog (DA) converter for converting the PWM signal outputted from the microcomputer into an analog signal and outputting a corresponding DC voltage to set the bandpass filter, can achieve the effect that it can be controlled without an external adjustment since the voltage for adjusting the center frequency of the bandpass filter is scanned in an appropriate range, and as a result, the shift in the center frequency of the bandpass filter due to the variation of the temperature and the applied voltage can be prevented, and consequently, the exact setting of the center frequency and the detectability of the pilot signal can be significantly enhanced.

Abstract: A method and apparatus is disclosed for encoding secondary signals, such as audio signals, within a television signal in a manner such that the signal may be either recorded on a video cassette or broadcast. The audio samples are encoded only on selected lines of each video frame which do not interfere with dedicated broadcast and cable lines and are not affected by head switching of a video cassette recorder. The audio samples are encoded only within an overscan portion of the selected lines such that the encoded samples do not interfere with other portions of the video signal. However, by encoding the samples within the overscan portion, the samples do not affect the displayed image. The secondary audio signal is sampled during equally spaced intervals throughout the video frame, then compressed and encoded only within selected horizontal lines. During decoding, the audio samples are decompressed and played back at the original sampling rate to provide audio playback.
