Most likely you can use the RSS Feeds and pipe it thru Roku. I have investigated that for Indonesia already and may have something soon to show.

Yes, you could do that, we don't have any samples that would show you how to elegantly display text, but it can definitely be done. It will require some skill at programming. The components to look at would be roImageCanvas and roScreen. If you have specific questions on how to implement various particular aspects of this, you can post them on this forum.

Actually, for anyone who is interested in Text display, here is a rudimentary Text wrapping function, where fo is an roFont, px is the type size, and maxwidth is the number of pixels. This function could be improved significantly, for example, maxwidth should be a separate parameter from paragraph width.

function linebreak(text as string,fo as object,px as integer,maxwidth as integer) as object
	
	timer=createobject("rotimespan")
	timer.mark()
	arr=text.tokenize(" ")
	line=arr[0]
	
	paragraph=[]
	length=fo.getonelinewidth(line,maxwidth)
	?"length: ";length;
	?"maxwidth: ";maxwidth
	inc=1
	
	while  inc < arr.count()-1 
			
			length=fo.getonelinewidth(line+" "+arr[inc],maxwidth)
			?"length: ";fo.getonelinewidth(line,maxwidth);"  line: ";line; 
			?"length: ";fo.getonelinewidth(line+" "+arr[inc],maxwidth);" line+: ";line+" "+arr[inc]
			
			if length >= maxwidth -30
				paragraph.push(line)
				length=0
				line=""
				line=line+arr[inc]
				inc=inc+1
			else if length < maxwidth-30 and paragraph.count()<2 then
				line=line+" "+arr[inc]
				inc=inc+1
			else
				line=line+" "+arr[inc]
				inc=inc+1
			end if
	end while
	line=line+" "+arr[inc]
	paragraph.push(line)
	'? "FINAL paragraph":
	'? paragraph
	'?"paragraph parsed in: ";timer.totalmilliseconds()
	return paragraph
end function
