SMIL is a markup language for multimedia contents. It helps you to create playlists with media elements. The language is based on XML and is an abbreviation for:
Synchronized Multimedia Integration Language
SMIL helps you create playlists with movie clips, images, and music streams that can also be time-controlled. You can customize the layout and configure multiple regions on the screen. These zones then play their content individually..
SMIL is becoming more and more popular in the digital signage market because it has a significant advantage::
For you, this means more independence, more competition, and more innovation.
If you have a SMIL compatible player, you can use SmilControl!
This gives you not only a much wider choice of devices. You can also manage players from different manufacturers by SmilControl and - if necessary - upgrade your media player to a newer model.
Also, you benefit from the fact that we as a supplier can concentrate fully on our software products. We do not have to develop and maintain an own complex markup language for multimedia.
The first version was standardized in 1998 by the W3C and extended the following years. The current standard in version 3.0 was adopted in 2008.
A first major industrial application of SMIL was in HD-DVD and MMS. It is also part of the current epub 3.2 standard for e-book readers. However, the language did not have a real breakthrough. It was not until 2008 that
the Taiwanese company IAdea discovered the language for its products and began to develop digital signage SMIL hardware players. Since then there has been
a kind of Renaissance.
For the industry, this was the first important step towards reducing dependencies. If someone wanted to operate a digital signage network before, he had to buy the server component (CMS) and the client software (media player) from a single source. Thanks to a uniform SMIL standard, it was now possible to use components from different manufacturers for this purpose.
Like HTML, SMIL is a registered industry standard. Just compare it to a web page: if it is in compliance with the standard, you can use any web browser. Mozilla, Chrome, Internet Explorer, Opera, Safari- no matter which page you go to; it is usually displayed in the same way except for a few small things. The same goes for the Digital Signage SMIL players.
SMIL has been tried-and-tested, it is robust and offers many functionalities.
The language describes in general the presentation of multimedia. No more - no less!
Die Sprache beschreibt allgemein wie multimediale Inhalte präsentiert bzeziehungsweise dargestellt werden. Nicht mehr und nicht weniger.
The following features are additionally required for the operation of a digital signage network:
Since these functionalities are not the job of SMIL, vendors may implement them differently.
Due to the openness of the standard, the expandability and the publicly accessible documentation on the websites of the W3C, any software developer can develop SMIL-compatible software components (player, CMS etc). There are no obstructive patents or the obligation to sign non-disclosure agreements. Thanks to the existing language features, SMIL can prevent the programmer from making wrong decisions about the control language design.
According to a study by the industry portal Invidis from 2012, more than 120 providers in Germany alone
offer digital signage solutions. More than 60% of these are smaller companies.
Many projects only start as an ancillary business with a minimum requirement profile. For example, because an important existing customer of an advertising agency requests only to play media in an endless loop. At this point in time, the company usually has little or no digital signage experience.
In the apparently simple implementation of customer requirements, coupled with the usual price and time pressure, decision makers often neglect conceptual sustainability. The main thing is that the important customer will be happy. Both the control language and the software go quickly and easily in the hand. As time passes, the requirements increase because of success, customer requirements, and technical innovation required. For example, the implementation of differentiated time controls.
This is the point where the probability of maneuvering into a technical dead end, which may become noticeable much later.
Eventually, a functional request comes up and during the realization, it becomes apparent, that the easy way was already blocked at the beginning of the project by a premature design decision. If time and manpower are lacking, complex workarounds have to be implemented. This often leads to side-effects in the code, which are difficult to locate. The system becomes more unstable, error-prone and the cost for maintenance and implementation of further functionalities increases immeasurably.
The scenario, of course, is not specific to digital signage. SMIL will not relieve us of the need for good quality assurance, communication and documentation. The management must also have an understanding of these lengthy processes. But at least we need to deal with one elementary problem less. SMIL already provides a sophisticated control language for our digital signage projects.
Why reinvent the wheel?
The standardization of SMIL enables specialized technical service providers. These may relate exclusively to one component, e.g. just the CMS, or as in the case of IAdea focus on hardware players. Without having to offer a complete solution, even smaller companies can reach the market faster with their innovations and new ideas.
The result is diversification. As even full-service providers can assemble their customized products more easily from a wider range of technical solutions.
The best-known suppliers are IAdea and Qbic International for about 2 years. Both companies openly document their functionalities at http://a-smil.org and http://open-smil.org. Planar and ViewSonic are two further companies which offer SMIL compatible players. In Germany, the company Isaria distributes its own developed digital signage SMIL Player based on Android for your projects.
There are a number of available software players that partially understand SMIL 2.1, e.g. Real Player or QuickTime and also the fully SMIL 3.0 compatible Ambulant. But all these players are not customized to the needs of the digital signage market. They lack the functions described above.
For these reasons, we decided in 2016 to invest in the development of a player Garlic Player. Which is available to anyone under a free license.
There are some CMS service providers who offer SMIL as an option or as an entry-level option. E. g. Easyscreen, Scala, Signagelive, Stinova, etc.
SmilControl has adopted SMIL exclusively for its same-named CMS, because we are convinced that the flexible combination of technology modules will be successful in the long term.
After HD-DVD and MMS are relics of the past, the language SMIL had a shadowy existence in public for a long time. It is only in their incarnation as Digital Signage SMIL that their significance grows again. With the exception of a few additional features, it supports our application profiles optimally. Their use opens up new markets and opportunities, even for smaller specialized suppliers. Without SMIL we would not start our business modell in 2012.
