Hi Futomi san,

Title and sub-title;
"Architecture and Requirements for Web-based Signage Player"
-- Core Feature
#I prefer 'feature' than 'profile'.

Add a Concept chapter before Terminology;
Concept:
The "Features for Web-based Signage Player" defines precise requirements for web-based signage 
players.

Web-based signage is digital signage whose contents are created by only web-technologies. Besides, 
it has a capability of connecting to a network. It is not a matter whether the network is the 
Internet or not. The web-based signage includes the terminal in an intranet.

Web-based Signage Player in this document is the composition of the device to play contents for Web 
based signage. However, this document is not aimed for limitation of underlying hardware and the 
operating system. Therefore, in this document, Web-based Signage Player is application software to 
play contents. 

Web-based signage Player is a set of an application and a runtime.

The application is comprised of the software such as frameworks or the libraries for signage. 
Architecture and functions of the application will be prescribed as features for web-based signage. 
The application is a set of JavaScript programs and style sheets and HTML. An application is run on 
a runtime, fetches contents form a content server, then plays the contents appropriately.

The runtime is common browsers typically. Or it may be software with the functions that is equal to 
common browsers associated with the operating system. On the other hand, it is not a dedicated 
subset or subset-based derivation of HTML5 in wide sense. That is, the runtime offers functions 
called HTML5 in the wide sense. The specifications of HTML5 in wide sense will be provided 
particularly by W3C.

Therefore, web-based signage player has a function of HTML5 in wide sense that runtime has. And this
 document does not restrict the function of the player for contents using functions and expressions 
based on HTML5 in wide sense even if it is out of the range of feature shown in this document,

The features for web-based signage player consist of a number of features. Basically, web-based 
signage is based on the core feature (this document). As necessary, web-based signage systems adopt 
the other features additionally.

Terminology chapter;
Items of Web-based signage, runtime and player are substituted with a concept chapter.


Regards,

Satoru
