Screen bum on televisions having Internet browser capability is avoided by removing the conventional static icons such as toolbars and buttons from the default browser and replacing their functions with keyboard keys. The invention is especially useful in projection televisions and with keyboards which have keys assigned to browser functions. Favorite URLs can be mapped to a favorite key by holding down the favorite key while a favorite web page is displayed.

An apparatus such as a television signal receiver controls an external device such as a digital recording/reproduction device via a digital data bus by remapping keys on a user input device. According to an exemplary embodiment, the apparatus includes an input/output terminal operative to enable signal transfer between the television signal receiver and an external device via a digital data bus. A processor is operative to detect a first command signal of a first control protocol from a user input device, and to detect one of first and second modes of the television signal receiver. The processor detects the first mode in response to making a connection between the television signal receiver and the external device via the digital data bus, and detects the second mode in response to terminating the connection between the television signal receiver and the external device via the digital data bus. The processor enables the input/output terminal to output a second command signal of a second control protocol to the external device via the digital data bus responsive to the first command signal if the first mode is detected. The processor enables a function of the television signal receiver responsive to the first command signal without enabling output of the second command signal to the external device if the second mode is detected.

A method for controlling a recording function of a video apparatus improves recording quality by preventing certain display functions of the apparatus from adversely affecting the resultant recording. A problem may arise in certain video signal processing apparatuses when the user selects a recording function after selecting a particular user-activated display function because the user-activated display function may result in the recording of the video signal in an undesired format, for example a different aspect ratio, or zoom mode. According to an exemplary embodiment, the present invention overcomes this problem by providing a method that includes the steps of detecting activation of a recording function of a video apparatus, and turning off a user-activated display function of the video apparatus responsive to the detection.

A system as described herein enables a user to access auxiliary information when viewing an enhanced performance television signal or program. Particularly, a television signal system is operative, configured, and/or enabled to allow a user to access and/or utilize auxiliary information when viewing a high definition or progressive-scan television signal. Briefly, an exemplary television signal system receives the auxiliary information/data (e.g. closed caption data) on a selected interlaced standard definition input, processes the auxiliary data, and combines or overlays the auxiliary data with a television (video) signal received on a selected input that does not have its own embedded auxiliary information/data. More particularly, an exemplary television signal system such as described herein involves using closed caption (CC) data from a standard definition signal, processing the CC data, and overlaying the CC data at a video rate of a higher definition signal selected for viewing that does not carry its own embedded closed caption data.
摘要:
A system, method and apparatus for displaying real time auxiliary information from a secondary source or input signal in combination with a program from a separate primary source. The auxiliary information (e.g. textual, graphical or video images) is selectable and is received through a second, integral or stand-alone tuner. The selected information can be displayed (1) continuously, (2) at predefined regular intervals, or (3) as the (defined) event(s) occur either in real time or in memory to provide a short delay time. The auxiliary information may be part of a currently transmitted data stream or as a separate data stream.
摘要:
An apparatus and a method for preventing a user from bypassing a viewer blocking system using program related information, such as content ratings, included in a program signal. The present invention prevents the user from exploiting the time delay associated with detecting, decoding and comparing the program related information by switching channels to observe portions of objectionable programs before the blocking system can react. The present system comprises a processor (110) which controls the output of a selected program signal (VIDEO, VIDEO IN, AUDIO IN) in response to a determination of whether an associated program related information meets a user selected blocking criteria. The processor blocks display of a program signal when a predetermined sequence of signal channel selections is detected and then continues to block the display of the program signal at least until the determination is performed. The predetermined sequence of signal channel selections may comprise continual re-tuning of the same channel and/or switching between two channels. The present method comprises detecting a particular sequence of signal channel selections and blocking the display of the program signal upon detecting the predetermined sequence. If the predetermined sequence of signal channel selections is detected the display blocking is maintained at least until a program related information associated with the program signal is detected and a determination of the satisfaction of a user selected blocking criteria is performed.
摘要:
An apparatus and a method for preventing a user from bypassing a viewer blocking system that uses program related information, such as content ratings, included in a program signal. The present invention prevents the user from exploiting the time delay associated with detecting, decoding and comparing the program related information by switching channels to observe portions of objectionable programs before the blocking system can react. The present apparatus comprises a processor (110) which provides an output signal (RGB OUT) derived from a selected program signal (VIDEO, VIDEO IN, AUDIO IN) of a selected signal channel and prevents or allows user access to the output signal in response to a determination of whether a user selected program blocking criteria is met. The processor modifies the output of a selected program signal upon user selection of a new signal channel if a default blocking mode is selected by the user, then continues to modify the program signal associated with the newly selected signal channel at least until the program related information is determined.
摘要:
A remote control is operative to transmit a remote control signal composed of a first portion and a second portion. The first and second portions are typically a pulse and a space. The pulse has a pulse width of a given duration within a pulse width range, while the space has a space width of a given duration within a space width range. An interrupt signal provided to indicate the end of transmission of the remote control signal is disabled when a space portion requires a space width greater than the space width range. The interrupt signal signaling the end of the remote control transmission is then disabled for a predetermined period of time essentially equivalent to a length of time that the additional space exceeds the space width. During the predetermined period of time, the remote control thus transmits a space. The interrupt signal is then re-enabled after expiration of the predetermined period of time in order to allow for another remote control transmission.
摘要:
Television apparatus includes first and second auxiliary data decoders for simultaneously extracting auxiliary data from respective first and second television signals to produce first and second auxiliary data. The data decoders can selectably extract data from one or more auxiliary data intervals, e.g., one or more line intervals during vertical blanking within a television signal. The first and second auxiliary data is coupled to a controller such as the main microprocessor of the television system. The second auxiliary data is coupled to the controller via an auxiliary data buffer and an I.sup.2 C serial data bus. The television signal from which the second auxiliary data is extracted can be provided by a second television signal source such as a second tuner or an external signal source (e.g., video cassette recorder, video disk player, and the like).
