A system and method for displaying still video images related to video content in an interactive broadcast television system. The system and method of the present invention may also be used for simulating an Internet home page on an interactive television system. The present invention thus supports hyperlinked web-like navigational capabilities in an interactive television system. According to the method of the present invention, the video delivery system provides or broadcasts one or more audio / video channels each comprising video content and also provides or broadcasts at least one still image channel comprising a plurality of still video images, preferably MPEG-2 compressed still images. The user or viewer can select options displayed on the television screen to view desired information. When the set top box receives user input selecting an option to view one of the linked still images, the set top box captures the requested image from the still image broadcast channel, stores the image in memory, and displays the captured still video image corresponding to the selection. The still image being displayed may have associated interactive program content for displaying further selections, wherein these selections may be for viewing other images or content, for ordering information, or purchasing products. The user can thus selectively navigate between the video content and stills in a web-like hyperlinked fashion.

Image enhancement by separating the image signals, either Y or RGB, into a series of bands and performing noise reduction on bands below a given frequency but not on bands above that frequency. The bands are summed to develop the image enhanced signals. This results in improved sharpness and masking of image processing pipeline artifacts. Chroma signals are not separated into bands but have noise reduction applied to the full bandwidth signals. The higher frequency band is attenuated or amplified based on light level. The noise reduction has thresholds based on measured parameters, such as signal frequency, gain and light level, provided in a lookup table. The window size used for the noise reduction varies with the light level as well, smaller windows sizes being used in bright light and increasing window sizes as light levels decrease. Panoramic images are handled in a similar fashion.
