IP Backup function:

Add a stream first or here we are using existing ones just to show how it works…
The Reason of this function is obvious?: If a mayor stream input will fail, the backup address will be
used to process it so the output encoding has still content. Usually as an example: If the HD channel
you are transcoding will be interrupted somehow, you create the backup channel from i.e. an SD
source stream.

As a Multicast capable Switch we recommend is the HP (ARUVA) 2530 24G or 48G.

(For Floor switches we have an own branded one and support IGMP as well) IGMP should be set to
ON in the port configs. The latest HP Firmware might not be the best choice. Better to test IGMP
functions before installation into a HOT running System and eventually do a downgrade of the
Firmware. This one works:

Note

Host Extensions for IP Multicasting [RFC1112] specifies the extensions required of a host
implementation of the Internet Protocol (IP) to support multicasting. The multicast
addresses are in the range 224.0.0.0 through 239.255.255.255. Address assignments are
listed below.

The range of addresses between 224.0.0.0 and 224.0.0.255, inclusive, is reserved for the
use of routing protocols and other low-level topology discovery or maintenance protocols,
such as gateway discovery and group membership reporting. Multicast routers should
not forward any multicast datagram with destination addresses in this range, regardless of
its TTL.

 Relative Addresses used with Scoped Multicast Addresses

Multicast (as opposed to unicast) is used to send UDP packets from 1 source to multiple
destination servers. This is useful for example for streaming from a satellite/DVB-T receiver
to multiple receiving PCs for playback. Multicast can also be used on the output of an
encoder to feed multiple streaming servers. Multicast only works with UDP and is not
possible with TCP due to the 2 way nature of TCP, most commonly multicast is used with
RTP and MPEG2-TS.

A multicast IP address must be chosen according to IANA information, we recommend
using an address in the range 239.0.0.0 to 239.255.255.255 as this is reserved for private
use. Using multicast addresses in the 224.0.0.0 range may clash with existing services and
cause your stream to fail. For more details see

http://www.iana.org/assignments/multicast-addresses/multicast-addresses.xml

Choosing a UDP port number for multicast streams is also important. Even if you use a
different multicast IP for each of your streams, we strongly recommend using different
UDP port numbers as well. This is because a server and all software running on the server
receives ALL multicast traffic on an open port and extra processing is required to filter out
the required traffic. If the each stream arrives on a different port, the server can safely
ignore any traffic on ports that are not open. Port numbers MUST be chosen so that don't
clash with any existing services or ephemeral ranges. The ephemeral range for Windows
Vista, 7, 2008 is 49152 to 65535, for older Windows it is 1025 to 5000 and for Linux it is
32768 to 61000. For more information on Windows see

http://support.microsoft.com/kb/929851 Care should also be taken to avoid system ports

0 to 1024. See http://www.iana.org/assignments/service-names-port-numbers/service-

names-port-numbers.xml Generally one of the unassigned User Ports (1024-49151) should

be used, you can run the netstat -abn (as admin under windows) command to see which
ports are currently in use.

Registered port

A registered port is a network port (a sub-address defined within the Internet Protocol, in
the range 1024–49151) assigned by the Internet Assigned Numbers Authority (IANA) (or by

Internet Corporation for Assigned Names and Numbers (ICANN) before March 21, 2001,

[1]

or by USC/ISI before 1998) for use with a certain protocol or application.

Ports with numbers 0–1023 are called system or well-known ports; ports with numbers
1024-49151 are called user or registered ports, and ports with numbers 49152-65535 are
called dynamic and/or private ports.

[2]

Both system and user ports are used by transport

protocols (TCP, UDP, DCCP, SCTP) to indicate an application or service.

 Ports 0–1023 – system or well-known ports
 Ports 1024–49151 – user or registered ports
 Ports >49151 – dynamic / private ports

https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

Range for Ephemeral port

The Internet Assigned Numbers Authority (IANA) suggests the range 49152 to 65535 (215+214 to
216−1) for dynamic or private ports.

[1]

Many Linux kernels use the port range 32768 to 61000.

[note 2]

FreeBSD has used the IANA port range
since release 4.6. Previous versions, including the Berkeley Software Distribution (BSD), use ports
1024 to 5000 as ephemeral ports.

[2][3]

Microsoft Windows operating systems through XP use the range 1025–5000 as ephemeral ports by

default.

[4]

Windows Vista, Windows 7, and Server 2008 use the IANA range by default.

[5]

Windows

Server 2003 uses the range 1025–5000 by default, until Microsoft security update MS08-037 from

2008 is installed, after which it uses the IANA range by default.

[6]

Windows Server 2008 with

Exchange Server 2007 installed has a default port range of 1025–60000.

[7]

In addition to the default
range, all versions of Windows since Windows 2000 have the option of specifying a custom range
anywhere within 1025–65535.

Length

Checksum

The UDP header consists of 4 fields, each of which is 2 bytes (16 bits).

[1]

The use of the fields "Checksum" and
"Source port" is optional in IPv4 (pink background in table). In IPv6 only the source port is optional (see
below).

Source port number

This field identifies the sender's port when meaningful and should be assumed to be the port to
reply to if needed. If not used, then it should be zero. If the source host is the client, the port
number is likely to be an ephemeral port number. If the source host is the server, the port number is
likely to be a well-known port number.

[4]

Destination port number

This field identifies the receiver's port and is required. Similar to source port number, if the client is
the destination host then the port number will likely be an ephemeral port number and if the
destination host is the server then the port number will likely be a well-known port number.

[4]

Length

A field that specifies the length in bytes of the UDP header and UDP data. The minimum length is 8
bytes because that is the length of the header. The field size sets a theoretical limit of 65,535 bytes
(8 byte header + 65,527 bytes of data) for a UDP datagram. However the actual limit for the data
length, which is imposed by the underlying IPv4 protocol, is 65,507 bytes (65,535 − 8 byte UDP
header − 20 byte IP header).

[4]

In IPv6 jumbograms it is possible to have UDP packets of size greater than 65,535 bytes.

[5]

RFC 2675
specifies that the length field is set to zero if the length of the UDP header plus UDP data is greater
than 65,535.

Checksum

The checksum field may be used for error-checking of the header and data. This field is optional in
IPv4, and mandatory in IPv6.

[6]

The field carries all-zeros if unused.

[7]

RTP:

a part from: https://tools.ietf.org/html/rfc3550

Chapter 11:
RTP relies on the underlying protocol(s) to provide demultiplexing of
RTP data and RTCP control streams. For UDP and similar protocols,
RTP SHOULD use an even destination port number and the corresponding
RTCP stream SHOULD use the next higher (odd) destination port number.
For applications that take a single port number as a parameter and
derive the RTP and RTCP port pair from that number, if an odd number

BLANKOM BTR-6000 Transcoder User Manual

Version 1.0 – 06-2018 Page - 28 -

is supplied then the application SHOULD replace that number with the
next lower (even) number to use as the base of the port pair. For
applications in which the RTP and RTCP destination port numbers are
specified via explicit, separate parameters (using a signaling
protocol or other means), the application MAY disregard the
restrictions that the port numbers be even/odd and consecutive
although the use of an even/odd port pair is still encouraged. The
RTP and RTCP port numbers MUST NOT be the same since RTP relies on
the port numbers to demultiplex the RTP data and RTCP control
streams.

In a unicast session, both participants need to identify a port pair
for receiving RTP and RTCP packets. Both participants MAY use the
same port pair. A participant MUST NOT assume that the source port
of the incoming RTP or RTCP packet can be used as the destination
port for outgoing RTP or RTCP packets. When RTP data packets are
being sent in both directions, each participant's RTCP SR packets
MUST be sent to the port that the other participant has specified for
reception of RTCP. The RTCP SR packets combine sender information
for the outgoing data plus reception report information for the
incoming data. If a side is not actively sending data (see Section

6.4), an RTCP RR packet is sent instead.
