28.7 Production Workflow

You should build an automated workflow for mobile-service content creation. The
Popwire Compression Engine supports watch folders and server-oriented solutions that
are ideal for this application. If you have live content to be streamed, then Popwire
Broadcaster may be just what you need. You can find out more about all of the Popwire
products at their web site.
The Compression Engine product is meant to be used for “industrial strength”
encoding systems. This product is designed to work in a server-based environment and
will automatically distribute work around a cluster if you have one. As part of the process,
you can apply filters to clean and de-interlace the content prior to compression.

28.8 Other Technologies to Explore

There are some important technologies and emerging standards relating to mobile sys-
tems. If you want to investigate these further, then searching the Internet for certain key-
words will lead you to some useful documents. Depending on the territory you are
targeting with your content for mobiles, these terms may be relevant to your operation:

DVB-H WiMAX

● ●

DMB BSAC

● ●

ISDB-T HSDPA

● ●

HSDPA (High Speed Downlink Packet Access) is a faster delivery technology devel-
oped by Motorola. This delivers 2 Mbps to the mobile device and Siemens has plans to intro-
duce capacities of up to 1 Gbps, which is about 20 times as fast as current technology allows.
Useful information about the technologies used by mobile operators and the companies that
develop them can be found at the Global mobile Suppliers Association (GSA) Web site.

28.8.1 Digital Video Broadcasting—Handheld

The Digital Video Broadcasting—Handheld (DVB-H) standard has been developed by the
DVB Organization for the broadcast of content that is like traditional TV to handheld
devices such as mobile phones. It has previously been known as DVB-M and DVB-X.
