Appl. No.:

10/144326

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04L 7/00
H04L 25/00

US Classification:

375355, 375371

Abstract:

A deserializer that deserializes a high data rate bit stream to extract a set of bits contained therein includes a data sampler, a serial-to-parallel converter, a windowing block, and a phase error detection block. The data sampler over samples the high data rate bit stream to produce a serial group of samples corresponding to the set of bits of the high data rate bit stream. The serial-to-parallel converter couples to the data sampler and converts the serial group of samples into a parallel group of samples. The windowing block receives the parallel group of samples and produces output bits corresponding to the set of bits. The phase error detection block couples to the windowing block, detects errors in the alignment of the overlapping sampling windows of the windowing block, and directs the windowing block to adjust the operation. The phase error detection block and the windowing block compensate for bit stream jitter and intersymbol interference.

International Classification:

G06F 3/033

US Classification:

345158

Abstract:

Provided are systems and methods for providing enhanced motion detection. One system providing enhanced motion detection includes a smart display, an interface subsystem including a human interface device (HID), and a console having a processor configured to form communication links with the smart display and the interface subsystem and to provide motion detection feedback, using the smart display, to a user of the HID, where the HID is configured to sense motion of the HID and utilize a predictive model to characterize the motion of the HID. One interface subsystem includes a camera to sense motion of a user of the HID. One processor is configured to negotiate a reduced response latency with the smart display.
