IP Receive - Stream Select (SFP A) [IP Mode]
[Qx IP / PHQXO-IP-DEC (Qx 12G)]
The ‘IP Receive - Stream Select (SFP A)’ window is where a stream can be selected for reception. An IP
video source can be switched here easily. Multicast status is displayed at the top of the instrument window,
and multicast requests can be setup and canceled via the submenu.
The instrument provides a list of all available streams - both multicast and unicast. For each stream, details
including: IP video protocol, IP address, UDP port and SSRC information are all displayed; and video format
information for the selected stream, stored at the IP level, is summarized in the ‘Receive Src IP’ pane.
Once selected, a new stream is received by pressing the ‘Receive Src IP’ pane.
The instrument window will indicate which stream the analyzer is currently locked to.
The submenu, accessed by right-clicking within the ‘IP Receive - Stream Select (SFP A)’ window calls up
multicast setup, SSRC receive conditions, and list clearing controls.
The displayed list of available streams can be cleared by selecting:
l Clear input list
Where an SSRC ID is included in an available stream, the tool can be set to only receive a stream with an
‘Exact’ ID match, or one with ‘Any’ value.
l SSRC match > [Exact, Any]
Multicast Setup
Streams can be accessed via an IGMPv2 or v3 multicast request. The details of the multicast to be joined
must be entered first. The destination IP address of the multicast can entered into the destination IP address
fields by keyboard or via the on-screen keypad:
l Multicast req: Dst IP addr > [224.0.0.1...239.255.255.255]
Streams transmitting on this multicast will be listed in the instrument window.
