Abstract: A television apparatus includes a front panel keyboard having first and second keys, and a controller for detecting a type of operational logic of the front panel keyboard. The controller applies a keyboard operational voltage to the front panel keyboard according to the detected type of operational logic. If the controller determines that the type of operational logic is negative, the controller applies the keyboard operational voltage to the front panel keyboard. Otherwise, if the controller determines that the type of operational logic is positive, the controller applies no keyboard operational voltage to the front panel keyboard.

Abstract: This invention concerns a system for the distribution of films by electronic means, and in particular, for ensuring a director's intended rendition of the images is attained in differing viewing conditions and technologies. Thus master data enabling the luminance and chromaticity of every part of every frame as previously displayed in a first display environment to be determined may be modified to achieve a similar subjective effect in a second display environment, the modification depending for example on data characterizing the said second display environment.

Abstract: A method and system for reducing burn-in of a display is disclosed. A plurality of assets containing text, graphics, and video are stored and then gathered. These assets are then assembled into a template to form a video frame or “screen”, which is subsequently output in a video transport stream or video display.

Abstract: An audio/video system comprises an audio signal processing path having an audio path delay and a video signal processing path having a video path delay. The audio path delay may be different from the video path delay. The audio path delay and/or the video path delay may change, for example because of replacement of a component within the audio signal processing path or the video signal processing path. Delay matching (synchronization) in the audio/video system comprises adjusting the audio path delay to be substantially equal to the video path delay. Matching the audio path delay to the video path delay generally includes adding delay to the signal processing path with the lesser delay.

Abstract: Overlaying visual interface information atop a video signal without obscuring desired features of the video signal. The video signal may contain one or more pre-selected features, such as text. Two or more display sections equally divide the video signal, and any pre-selected features in the video signal are identified as residing in particular display sections. Depending on the nature of the features, the selected visual interface information is placed atop the video signal in a display section not containing any pre-selected features so as not to cover or obscure the features or is placed over specified features that do not significantly contribute to the video signal, such as blank or static screen regions. A hierarchy of preferred display sections for placing the visual interface information may be created to optimize the placement thereof. The methods for overlaying visual interface information find particular application with interactive television systems.

Abstract: An LCD TV capable of being used as a music station only, which can turn off the internal video decoder and the internal backlight power when the LCD TV only desires to output an audio. The LCD TV panel has a backlight control terminal with a first state and a second state to turn on/off the internal backlight power based on the first or second state. A video decoder has a working mode and a standby mode. When an instruction received by a command input device is a panel backlight power turning-off instruction, a controller produces a control signal to set the backlight control terminal to the second state to thereby drive the LCD TV panel to turn off the backlight power thereon and set the video decoder to the standby mode.

Abstract: A technique to stabilize subcarrier generation in a line-locked digital video system, caused by simultaneous locking of the genlock device causing continuous changing of a shared clock signal, by calculating a time shift occurring in an output waveform, converting the time shift into an equivalent phase shift and sending a corresponding phase correction number to a waveform generator block to correct the time shift, and thus stabilize subcarrier generation.
