Abstract
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.
