Roku HD2000 manual Scripts, Hello world

specification indicates that “video.mpg” will start playing at 4:00 PM every Wednesday in January, 2008. The playlist “breakfast.bsp” will start playing at 7:00 AM during January, 2008. Finally, “demo.csv” will be launched everyday in January, 2008, at 2:00 PM.

Note that blank lines can be added (as above) to autoschedule.txt files to improve readability. Additionally, “REM” lines can be added to annotate these files.

Scripts

BrightSign can be used without any knowledge of scripts to accomplish common goals such as playing looping video or playing a slideshow (see the prior section in this manual “Playing Media”). It’s easy to control your digital signs or kiosks with a USB keyboard or remote using a simple script. In addition, using CSV files you can create more sophisticated signs. But by adding scripts, you can create the most interactive digital signs or kiosks. For a fee, Roku can help you write scripts. Contact brightsignsales@rokulabs.com for more information.

A script is a simple program that controls behaviors, like video playback, based on events such as button presses. Scripts are also commonly used on PCs and Web Sites. For example, Microsoft Office “macros” are often Basic Scripts. Adobe Flash apps often rely on ActionScripts for their logic, and web pages are often driven by scripts written in PHP, Perl, or JavaScript. If you don’t have scripting skills in-house, IT and Web developers can be contracted to write scripts for you. Roku can also be contracted to develop custom scripts and applications (contact brightsignsales@rokulabs.com).

BrightSign has a built in scripting language (called BrightScript), similar in many ways to the Basic found in Microsoft Office, or Windows XP “Windows Script Hosting” VBScript.

Scripts can be as simple as one or two lines, and as complicated as thousands of lines.

2.Save “hello.bas” into the root directory of a CF card

3.Insert the CF card into BrightSign

4.Connect the serial port of BrightSign to you PC using a null modem cable, and run hyperterminal (see the “Shell” section of this manual for more details).

5.Power up BrightSign.
