Abstract: A method for denoising a video signal includes (i) generating a first low-frequency frame, including one or more first low-spatial-frequency components of a first video frame of the video, by filtering one or more first high-spatial-frequency components from the first video frame; and (ii) generating a first filtered frame by recursively filtering the first low-frequency frame. The method also includes (iii) generating a second low-frequency frame from a second video frame of the video subsequent to the first video frame, by filtering one or more second high-spatial-frequency components from the second video frame; (iv) generating a high-frequency frame from the second video frame and the second low-frequency frame; (v) recursively filtering the second low-frequency frame with the first filtered frame to yield a denoised low-frequency frame; and (vi) generating a denoised video frame by combining the denoised low-frequency frame with the high-frequency frame.

Abstract: A system for Internet appliance data entry and navigation includes a reduced keyset remote control unit transmitting a user input keystroke sequence. An Internet appliance receives and parses the keystroke sequence, placing the parsed data into an input buffer. An Internet appliance browser accesses user interface display screens from remote storage via a communications network. The buffer contents define a window within an accessed display screen. The Internet appliance converts the composite display screen for output to a standard television receiver. A user makes option choices and navigates the user interface display screens by activating hyperlinks within the accessed display screens. A standard telephone keypad arrangement is used to create the keystroke sequence, permitting use of a standard or wireless telephone and a hand-held remote control unit for system input and control. An alternative embodiment permits voice input of text, numbers, special symbols, and shortcuts in many languages.

Abstract: A Fax-compatible Internet appliance includes a network connection section for communication with a network using both data protocols and fax protocols, a video section including a video signal output for outputting video signals to be displayed on a video display, a user interface signal receiver for receiving user interface signals generated by a reduced-keyset user interface device, and a processing unit which controls the network connection section and the video section to generate video signals for displaying received fax messages on the video display. The processing unit provides user interface functions via the video display and user interface signals, the interface functions enabling the user to control transmission, reception and display of fax messages solely through the reduced-keyset user interface unit.

Abstract: A web browser application implemented in an Internet appliance for accessing information on the Internet. The Internet appliance has a display device and using a reduced-keyset user interface device having only direction keys, numeric keys, and a number of function keys for user input. The browser displays a user interface screen divided into a primary screen area for displaying information and one or more control areas containing mode icons and command icons. In a navigate mode, the browser displays a plurality of interface elements in the primary screen area, each interface element representing a web page. The user accesses one of the web pages through the use of the keys. In a browse mode, the browser displays page contents of a web page in the primary screen area, the web page including one or more interface elements. The user browses through the web pages through the use of the reduced-keyset user interface device.

Abstract: A network access device uses a standard video display to show functional choices and network content received from the Internet to a user. The user directs the functional operation of the network access device with a simple reduced keyset remote control unit having a relatively small number of keys similar to a consumer remote control used for television receivers and video recorders. The control choices are displayed to the user in a unique format with elements associated to characters corresponding to the same characters in the reduced keyset. The display format uses several display areas, some of which can be designated as input focus areas, any one of which can be active at a given time. The device affords low cost ready access to the informational capabilities of the Internet for users at all skill levels by eliminating a full text keyboard and a mouse.
