    摘要: A network device comprising asymmetric, multi-rate, Ethernet MAC and asymmetric, multi-rate, Ethernet PHY communicates signals via a network utilizing A/V bridging services. Higher bandwidth A/V signals are communicated and lower bandwidth signals are received or vice versa. Signals are communicated based on a plurality of different Ethernet protocols and/or data rates. Signals may be communicated based on 10GBASE-T in a first direction and based on a lower rate Ethernet protocol in a second direction. Extended range mode may be utilized. PDUs comprise time stamps, traffic class designations and/or destination addresses. Data rate requests, resource reservation messages and/or registration for delivery of PDUs may be communicated. Time stamps enable end to end transport within a specified latency target. Video signals may be compressed, uncompressed, encrypted, unencrypted and/or formatted for a video display interface.

    摘要: A system and method for achieving higher data rates in physical layer devices. Costs imposed by large data rate increases represented by generational increases in Ethernet standards activities are avoided through physical layer device modifications that enable marginal increases in data bandwidth. Building-block reuse can be promoted through the selective use of clocking rate increase, increase in coding efficiency, and bit reuse.

    摘要: A system and method for energy savings on a PHY/MAC interface for energy efficient Ethernet. Power savings for a PHY due to low-link utilization can also be realized in the higher layer elements that interface with the PHY. In one embodiment, subrating is implemented on a MAC/PHY interface to match a subrating of the PHY with a remote link partner. This subrating is less than the full capacity rate and can be zero.

    摘要: Aspects of a method and system for energy efficient signaling for 100 mbps Ethernet using a subset are provided. In this regard, a network device enabled to communicate over a network link at 1 Gbps or faster may be configured to communicate over the network link at, or approximately at, 100 Mbps by reducing a number of active channels over which the network device communicates and/or reducing a size of a signal constellation utilized by the network device to encode data. The device may communicate according to 1GBASE-T or 10GBASE-T standards. The number of active channels may be reduced to a single bidirectional channel or two unidirectional channels. The signal constellation may be reduced to two or three levels. One or more components of the network device may be unnecessary for recovering data when communicating at 100 Mbps and may thus be powered down, or placed into a lower power mode.
