Appl. No.:

12/433677

Inventors:

Scott J. Bleiweiss - Upton MA, US
Victor Odryna - Acton MA, US
Stephen D. Metzger - Harvard MA, US

Assignee:

Zeevee, Inc. - Littleton MA

International Classification:

H04N 7/173

US Classification:

725 95, 725120

Abstract:

A video controller selects a channel for premises broadcasting to a premises television based on a fast scan of signal strength in channels available over a premises media. The signal strength of certain filtered channel frequencies can be evaluated to determine if a channel is occupied. Unoccupied channels can be ranked in relation to nearby occupied or unoccupied channels. The nearby channels may be ranked in terms of the signal strength content in relation to the channel being evaluated. The video controller can select an unoccupied channel with an optimal ranking to permit premises broadcasting with reduced interference or conflict with other channels.

Assignee:

Zeevee, Inc. - Littleton MA

International Classification:

H04N 7/18

US Classification:

725 74, 725 82

Abstract:

A video controller broadcasts input video through a premises media, such as a coaxial cable to one or more premises televisions or television channels. When a PC provides the input video, a mode change may occur to direct the video to the PC monitor or to the broadcast output. The video resolution of the PC is set to provide a desired digital television resolution with broadcast video. An audio driver may be used to provide USB audio output from the PC. When the PC monitor or broadcast output is selected for video output, the non-selected output is disabled or provided with a video indication that another video output is active. An EDID can be captured from the PC or PC monitor to assist with mode changes and setting PC video resolution. The input video may be provided directly from a digital video source and broadcast to selected televisions or channels.

International Classification:

G06F015/16

US Classification:

709/230000

Abstract:

In one general aspect, a network communication unit is disclosed that includes connection servicing logic that is responsive to transport-layer headers and is operative to service virtual, error-free network connections. A programmable parser is responsive to the connection servicing logic and is operative to parse application-level information received by the connection servicing logic for at least a first of the connections. Also included is application processing logic that is responsive to the parser and operative to operate on information received through at least the first of the connections based on parsing results from the parser.

Assignee:

Digital Equipment Corporation - Maynard MA

International Classification:

H04J 302

US Classification:

370 851

Abstract:

A terminal server architecture includes a central processing unit (CPU), a data movement module, local area network (LAN) interface and a plurality of connected terminals. The CPU manages pointers to data using command status registers to instruct the data movement module to actually perform data movement between the terminals and the LAN.
