An intelligent device is configured to receive a DTV signal that includes audio/visual information as well as data signals in a datacast format. The datacast format includes web pages, e.g., in the HTML (hypertext markup language) format of the world wide web. An intelligent filter modifies itself based on user behavior and user preferences in terms of the web pages that a viewer routinely visits. The intelligent filter is then used to identify certain web pages of the pages that are being broadcast and these identified web pages are stored in a cache memory for later use by the viewer. A second tuner can be used to poll multiple channels when updating the cached contents. Cached web pages avoid broadcast latencies (due to periodic updating) and thereby are displayed faster to the viewer.

Method and system for receiving and processing digital content

Embodiments of the present invention are directed to a method of storing digital content in a digital electronic system. In one embodiment, datacast information decoded from a digital media signal is monitored to identify newly-received digital content. The monitoring includes configuring a decoder to receive and decode the datacast information, identifying newly-received digital content from the datacast information, and updating an intelligent filter based upon the newly-received digital content, wherein the intelligent filter records the newly-received digital content. Additionally, the monitoring may include repeating the configuring, identifying, and updating. Thereafter, any of the newly-received digital content that is recorded in the intelligent filter may be stored into a cache memory.

The present invention provides for a method of and apparatus for compressing and uncompressing image data. According to one embodiment of the present invention, the method of compressing a color cell comprises the steps of: defining at least four luminance levels of the color cell; generating a bitmask for the color cell, the bitmask having a plurality of entries each corresponding to a respective one of the pixels, each of the entries for storing data identifying one of the luminance levels associated with a corresponding one of the pixels; calculating a first average color of pixels associated with a first one of the luminance levels; calculating a second average color of pixels associated with a second one of the luminance levels; and storing the bitmask in association with the first average color and the second average color. In one embodiment, the color cell includes a matrix of 4&#xd7;4 pixels, the bitmask includes 32-bits and each of the color values includes 16-bits such that a compression rate of 4-bits per pixel is achieved. The present invention is particularly applicable to compress texture data such that the texture data can be more efficiently cached and moved during texture mapping. In that embodiment, the present invention can also support the compression of luminance, intensity and alpha textures.

A combiner for optical beams includes a substrate overlaid by a multi-layer dielectric film stack. The substrate is a clear material and the dielectric film stack is a series of alternating layer of high and low refractive index. This gives the combiner relatively high reflectivity across UV wavelengths and relatively high transmissivity in the visible and longer wavelengths and allows visible light to pass through the combiner while UV light is reflected. At the same time dielectric film stack has minimal absorption and scatter. This means that the intensity of visible light maintains at least 90% of its intensity as it passes through combiner and UV light retains at least 90% of its intensity as it is reflected by combiner.
