Abstract
An enhanced multimedia over coax alliance (MoCA) implementation having a single Receive (Rx) physical (Phy) module that is arranged to receive data via one of at least two Rx radio frequency (RF) modules, which are arranged to be in communication with a coaxial cable, and at least two transmit (Tx) Phy modules respectively arranged to be in communication with two Tx RF modules, which are also arranged to be in communication with the coaxial cable.
Claims22
An apparatus comprising:
- a multimedia over coax alliance (MoCA) implementation having a processor and a memory arranged to be in communication with one another, and a direct memory access (DMA) module arranged to be in communication with the memory and an external interface;
- the MoCA implementation further comprising a single Receive (Rx) physical (Phy) module that is arranged to receive data via one of at least two Rx radio frequency (RF) modules, which are arranged to be in communication with a coaxial cable, and
- at least two transmit (Tx) Phy modules respectively arranged to be in communication with two Tx RF modules, which are also arranged to be in communication with the coaxial cable.
A multimedia over coax alliance (MoCA) implementation, comprising:
- a single Receive (Rx) physical (Phy) module selectably connected to one of at least two Rx radio frequency (RF) modulator/demodulator modules, respectively corresponding to two channels, that are both arranged to be in communication with a coaxial cable, and
- at least two transmit (Tx) Phy modules respectively arranged to be in communication with two Tx RF modulator/demodulator modules, respectively corresponding to the two channels, that are also both arranged to be in communication with the coaxial cable.
A method comprising:
- sending, from a first device over a first channel, a first data stream to a second device operating in accordance with conventional Multimedia over Coax (MoCA);
- sending, at the same time as the first data stream, from a third device over a second channel, a second data stream to a fourth device,
- wherein the first channel and the second channel are defined as distinct frequency bands on a single coaxial network, and the second channel is calibrated using an already-calibrated first channel calibrated in accordance with conventional MoCA.
A method comprising:
- on a first single device implementing multimedia over coax (MoCA), selecting both a first channel and a second channel among a plurality of possible channels in a single MoCA network;
- simultaneously transmitting a first data steam over the first channel and a second data stream over the second channel;
- and
- receiving the first data stream by a second device implementing MoCA and receiving the second data stream by a third device implementing MoCA.
