ETHERNET INTERFACE

Overview

AP0201AT’s Ethernet mode has complete support for

configuring the part and streaming video out. By default

IPv4 and IPv6 are enabled. The default MAC address and IP

address are in the table below. For a complete set of default

settings and configurable variables refer to the AP0201AT

protocols to synchronize several cameras.

IPv4

IPv6

fe80::ff:fe00:0

AP0201AT also supports a UDP−based protocol with ON

Semiconductor host commands. Using this protocol all

registers and variables are accessible.

AP0201AT MAC supports MII, GMII and RMII

protocols. Video can be streamed in MJPEG or H.264 format

over RTP or AVB (IEEE 1722a) protocols.

Registers and variables can be modified using HCI access

commands over Ethernet or through the serial interface. For

initial settings of these variables, firmware will check NVM

before booting up. (Please refer to the network section of the

HCI document for a discussion of all Ethernet firmware and

hardware variables.)

Protocol

The AP0201AT supports the following Ethernet

protocols.

• IP Protocols:

♦ IPv4 − Fully supported. ICMP, IGMP, ARP, UDP

and TCP

♦ IPv6 − Please talk to your design support engineer

• Command Protocols

♦ UDP − ON Semiconductor UDP−based Host

command protocol

♦ Some/IP

• Streaming Protocol:

♦ AVB (IEEE 1722) – The AP0201AT can be

configured to send H.264 or MJPEG video packets

over IEEE 1722 protocol or RTP protocol.

♦ IEEE 1722 is a layer 2 transport protocol. The

destination MAC address, VLAN number and

stream ID are configurable.

♦ RTP − Real−time Transport Protocol: RTP is

designed for end−to−end transfer of streaming video.

destination ip address, ,received port and MAC

address are configurable.

• Video Compression Protocol:

♦ H.264 – profiles supported: constrained baseline

(intra frames only) and high10intra level required:

up to 5.0 Both Annex B and RFC6184 formatting

are supported.

♦ MJPEG – JPEG compression of YCbCr 4:2:0

images with standard headers or RFC2435 headers.

• Precision Time Protocol:

♦ IEEE 1588−2008 (PTP)

♦ Delay Mechanism

− End−to−End (Multicast)

− Peer−to−Peer (Multicast)

♦ PTP Operational Mode

− Master

− Slave (default)

♦ Best Master Clock (BMC) Algorithm

♦ PTP Supported Messages

− Announce message

− Sync and Follow_Up message

− Delay_Req and Delay_Resp messages

− Pdelay_req and Pdelay_Resp_Follow_Up

messages

− Management message

♦ IEEE 802.1as (gPTP)

• Configuration Protocols

♦ DHCP4 − IP address, Subnet Mask, Domain Name,

and Host Name can be updated via DHCP4

♦ DHCP6

• Custom Diagnostic Protocol − ON Semiconductor

command protocol can be used to retrieve diagnostic
