16. _M_P_E_G__a_n_d__C_i_n_e_p_a_k__E_n_c_o_d_e_r__L_i_c_e_n_s_e_s
The MPEG and Cinepakr software compressors included in the
IRIS Digital Media Execution Environment require software
licenses in order to operate. This chapter defines some
important software licensing terms, describes the basic
procedure for obtaining, installing, and testing a software
licenses for the MPEG and Cinepak Encoders, and lists
addresses and phone numbers that you can use to contact
Silicon Graphics License Administration.
For more information about software licenses, see the
_N_e_t_w_o_r_k _L_i_c_e_n_s_e _S_y_s_t_e_m _A_d_m_i_n_i_s_t_r_a_t_i_o_n _G_u_i_d_e, which provides
detailed information on obtaining, installing, using, and
administering software licenses. It is included in the
system software documentation; the online version is in the
subsystem _n_e_t_l_s__e_o_e._b_o_o_k_s._N_e_t_L_S.
16.1 _A__F_e_w__D_e_f_i_n_i_t_i_o_n_s
A _s_o_f_t_w_a_r_e _l_i_c_e_n_s_e is a collection of information that,
after installation, allows you to use a licensed software
product on one or more systems. The software license
information includes the license type, the license
expiration date, a license password, and system
identification numbers (_s_y_s_i_n_f_o and serial numbers). You
can get a system's sysinfo number by giving the command
/etc/sysinfo -s. The license must be installed on the
system that has the sysinfo number included in the software
license information. If the sysinfo is ``Any,'' the
software license can be installed on any system.
There are two types of software licenses, _n_o_d_e-_l_o_c_k_e_d and
_c_o_n_c_u_r_r_e_n_t, and two durations of software licenses,
_t_e_m_p_o_r_a_r_y and _p_e_r_m_a_n_e_n_t:
node-locked A node-locked license is installed on a
particular system (node) and allows the
licensed software to run on that system.
concurrent A concurrent license allows the licensed
software to run on one or more systems in the
network simultaneously. The number of systems
(nodes) allowed is included in the software
license information. The system on which a
concurrent license is installed must be
configured as a Network License Server. Any
system on the same network must be configured
as a Global Location Broker. (See the _N_e_t_w_o_r_k
_L_i_c_e_n_s_e _S_y_s_t_e_m _A_d_m_i_n_i_s_t_r_a_t_i_o_n _G_u_i_d_e for more
information about Network License Servers and

Global Location Brokers.)
temporary A temporary license allows you to use the
licensed software for a short period, typically
a week to several months. The expiration date
tells you the last date on which you can use
the licensed software. Temporary licenses are
often shipped with software so that you can use
the software before a permanent license is
issued.
permanent A permanent license allows you to use this
release of the licensed software for a very
long time. For example, an expiration date in
the year 2038 indicates a permanent license.
Permanent licenses are issued only for software
that has been purchased.
16.2 _O_b_t_a_i_n_i_n_g__a_n_d__I_n_s_t_a_l_l_i_n_g__a__S_o_f_t_w_a_r_e__L_i_c_e_n_s_e
This section explains the procedure for obtaining and
installing a software license: checking to see if you have
received software license information, determining if you
need to install a license, requesting software license
information if you need it, identifying the system on which
you will install the license, installing the software
license information, and verifying that the license is
working.
1. Check to see if you have received software license
information.
Software license information is distributed in several
ways: on labels attached to a Software License
Registration card, on sheets of paper included with
the product, or by mail, FAX, or electronic mail.
2. Determine if you need to install a software license.
You may or may not need to install software licenses
for the MPEG Encoder and Cinepak Encoder:
+o If you are simply updating your system to this
release of the IRIS Digital Media Execution
Environment and IRIS Digital Media Tools, you may
not need to install a new license at this time;
your already-installed license may continue to
work.
+o If you have received both a temporary license and
a permanent software license, install the
- 3 -
permanent license; do not install the temporary
license.
+o If you have received a permanent license, you
should install it because it enables you to use
the software that you have purchased.
+o If concurrent licenses are used at your site and
you plan to use an already-installed license, you
can install and use the licensed software on your
system without installing a license.
+o If you have received a temporary software license
and do not need to use the software immediately,
you may choose to wait to install a license until
you obtain the permanent license.
3. Request a software license if you don't have a
software license at all, or if you have a temporary
license and need a permanent license.
To obtain a software license, fill out the Software
License Registration card that was included with the
software (or the replica in the _N_e_t_w_o_r_k _L_i_c_e_n_s_e _S_y_s_t_e_m
_A_d_m_i_n_i_s_t_r_a_t_i_o_n _G_u_i_d_e). Send the information or the
card by electronic mail (preferred), FAX, or mail to
Silicon Graphics License Administration or your local
service provider (see the next section for addresses).
After your request is received by Silicon Graphics or
your local service provider, you should receive a
software license within two business days.
4. Identify the system on which you will install the
software license.
Because software license information usually must be
installed on a particular system, follow these
guidelines:
+o If the sysinfo is a number, identify the system
that returns that number as the output of the
command /etc/sysinfo -s. (It may be easier to
identify the system using the serial number,
which is included in the software license
information.)
+o If the sysinfo is ``Any,'' you can install the
license on any system you choose.
+o If the sysinfo number included with the software
license information doesn't match the sysinfo
- 4 -
number of the system on which you want to install
the license, contact Silicon Graphics License
Administration.
5. Install the software license (temporary or permanent).
Check the ``license type'' listed in the software
license information to find out whether the license is
a node-locked license or a concurrent license. The
installation procedure depends on the license type:
+o If it is a node-locked license, see Chapter 3,
``Installing Node-locked Licenses,'' in the
_N_e_t_w_o_r_k _L_i_c_e_n_s_e _S_y_s_t_e_m _A_d_m_i_n_i_s_t_r_a_t_i_o_n _G_u_i_d_e for
instructions on installing the license.
+o If the license is a concurrent license, you may
need to configure the system on which you plan to
install the license as a Network License Server.
If there is no Global Location Broker on your
network, you must set up a system as a Global
Location Broker, too. See Chapter 4, ``Setting
Up Global Location Brokers and Network License
Servers,'' of the _N_e_t_w_o_r_k _L_i_c_e_n_s_e _S_y_s_t_e_m
_A_d_m_i_n_i_s_t_r_a_t_i_o_n _G_u_i_d_e for instructions. After the
Network License Server and Global Location Broker
are set up, follow the instructions in Chapter 5,
``Installing Concurrent Licenses,'' of the same
guide to install the license on the Network
License Server.
6. Verify that the software license has been successfully
installed.
To verify that the software license is working, try
creating an MPEG file or a QuickTime Cinepak file
using one of the digital media conversion programs
installed from _d_m_e_d_i_a__e_o_e or _d_m_e_d_i_a__t_o_o_l_s.
The programs which can be used to create MPEG-1 files
are _d_m_c_o_n_v_e_r_t(_1) and _M_e_d_i_a_C_o_n_v_e_r_t(_1).
The programs which can be used to create QuickTime
Cinepak files are _d_m_c_o_n_v_e_r_t(_1) and _M_o_v_i_e_M_a_k_e_r(_1).
Here is a sample command-line invocation of _d_m_c_o_n_v_e_r_t
which converts the sample movie _s_o_m_e_r_s_a_u_l_t._m_o_v_i_e into
an MPEG movie:
dmconvert -v -f mpeg1s -p audio -p video,rate=30
/usr/share/data/movies/somersault.movie

Here is a sample command-line invocation of _d_m_c_o_n_v_e_r_t
which converts the sample movie _s_o_m_e_r_s_a_u_l_t._m_o_v_i_e into
a QuickTime Cinepak movie:
dmconvert -v -f qt -p audio -p video,comp=qt_cvid
/usr/share/data/movies/somersault.movie
out.mov
If you installed a temporary license and you are
entitled to a permanent license, replace the temporary
license with a permanent license as soon as possible
to ensure uninterrupted use of the Silicon Graphics
MPEG Encoder or Silicon Graphics Cinepak Encoder.
