0xAC
– Third Byte
0xAD
– Fourth Byte
For the IP address to take effect the last byte (register 0xAD) must be written to. Once
all bytes have been update the IP address can be read back using register 0xAA to
confirm the change is correct.
Network RX
The network is capable of receiving user UDP packets. In the default configuration
these packets are only for the Decoder Module. The decoder module expects
Transport Stream data transmitted via UDP on port 1234. The network core is capable
of receiving UDP packets on all ports from any IP address, however for demo
applications the UDP Port is locked to 1234.
Network TX
The network is capable of sending user UDP packets. The default application for
network transmission is the Encoder Modules. The default transmission UDP port is
1234, however this can be changed via the API (0xA4). The default
Target/Transmission IP can be read from API Register 0xA0. Typically this IP will be
192.168.x.xxx. The target IP is changed in the same way the boards IP address is
changed using the following registers:
0xA0
– First Byte
0xA1
– Second Byte
0xA2
– Third Byte
0xA3
– Fourth Byte
The target address is readable using any of the above registers. The target computer
or device must be capable of sending IP ARP replies to be connectable. The determine
if the target IP is reachable bit 10 of register 0xAF can be check. When it is '1' the
target can be reached. When '0' the target has not responded or can not be found.
Sending / Receiving Transport Streams
Receiving Transport Streams (Encoder)
Encoder modules are capable of sending transport stream via UDP. Once the Network
stack has been configured correctly, the target IP has been discovered, and the
Encoder has a valid input (Video), the transport stream will be transmitted.
To receive the transport stream SOC suggests two possible methods, however others
are possible as well.
