Abstract
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.

24. A method of managing digital content, the method comprising:
-
scanning a first channel for a first portion of digital content; responsive to not detecting the first portion of digital content at least during a time period, ceasing scanning the first channel and scanning a second channel for the first portion of digital content; responsive to detecting the first portion of digital content during the time period, accessing the first portion of digital content using the first channel; comparing a first identifier to a plurality of identifiers to determine whether the plurality of identifiers comprises the first identifier, wherein the first identifier is associated with the first portion of digital content and wherein the plurality of identifiers is established based on past user downloading of digital content and not on user input of preferences; responsive to a determination that the plurality of identifiers comprises the first identifier, storing the first portion of digital content in a memory of the digital electronic system, wherein the storing is performed contemporaneously with a processing of other content accessed using a second channel; responsive to a user request for a second portion of digital content, determining if the second portion of digital content is stored in the memory; and accessing the second portion of digital content from the memory responsive to a determination that the second portion of digital content is stored in the memory. - View Dependent Claims (25, 26, 27, 28, 29, 30)

31. A system comprising a processor and a memory, wherein the memory comprises instructions that when executed by the system implement a method of managing digital content, the method comprising:
-
accessing a first portion of digital content using a first channel, wherein the first channel is selected under program control by a component of a digital electronic system; comparing a first identifier to a plurality of identifiers to determine whether the plurality of identifiers comprises the first identifier, wherein the first identifier is associated with the first portion of digital content wherein the plurality of identifiers is established based on past user downloading of digital content; responsive to a determination that the plurality of identifiers comprises the first identifier, storing the first portion of digital content in a memory of the digital electronic system, wherein the storing is performed with a processing of other content accessed using a second channel; and responsive to a user request for a second portion of digital content, accessing the second portion of digital content from the memory if the second portion of digital content is stored in the memory. - View Dependent Claims (32, 33, 34, 35, 36, 37)

38. A computer-readable memory having computer-readable program code embodied therein for causing a computer system to perform a method of managing digital content in a digital electronic system, the method comprising:
-
accessing a first portion of digital content using a first channel; comparing a first identifier to a plurality of identifiers to determine whether the plurality of identifiers comprises the first identifier, wherein the first identifier is associated with the first portion of digital content, wherein the plurality of identifiers is established based on past user downloading of digital content; responsive to a determination that the plurality of identifiers comprises the first identifier, storing the first portion of digital content in a memory of the digital electronic system, wherein the storing is performed with a processing of other content accessed using a second channel; responsive to a user request for a second portion of digital content, determining if the second portion of digital content is stored in the memory; and accessing the second portion of digital content from the memory if the second portion of digital content is stored in the memory otherwise accessing the second portion of digital content over the internet. - View Dependent Claims (39, 40, 41, 42, 43, 44)
