Code for the City Of Toronto Traffic and Information Mobile DTV App Now Posted

The City Of Toronto Traffic and Information App. Click for larger image.

The full source code for the City Of Toronto Traffic and Information App shown at NAB 2012 has been posted. It can be accessed from the Downloads menu at Those interested will find detailed information on how to run the files using Ubuntu Linux. Where possible SVG, .sh and XSLT files have been coded so programmers can learn how the coding works in the app with the hope the knowledge can be transferred to those interested in using the app.

Where possible files have been constructed with comments to assist programmers to learn how the app was constructed. Click for larger image.

Also published were all the ATSC TechZone Pavilion booth posters, PowerPoint slides (with notes) as well as a video of my NAB presentation on the NAB 2012 Materials menu located on the website.

Community Discussion for moved to 8-VSB Mobile DTV on LinkedIn

I’m happy to report that we have moved our community discussion to the 8-VSB Mobile DTV group on LinkedIn. The group has a number of members who are keenly interested in this area with varying backgrounds so it’s a good spot if your looking for input on this subject.

Site Update Underway

You’ll notice a big change to the content on this site which will take a week or so. I’ve just pulled a number of past posts from the site. I will be posting the materials based on what we will be showing at NAB 2012 as the week progresses.

Ryerson’s ATSC M/H Content Group to Demonstrate Interactive Mobile DTV Prototypes in the ATSC TechZone Pavilion at NAB 2012

Ryerson’s ATSC M/H Content Group will once again be at the National Association of Broadcasters Conference but this year they will be located in the ATSC TechZone Pavilion.  The ATSC TechZone Pavilion is located at Booth Number N4039 which is located in the North Hall of the Las Vegas Convention Center. The group will be showing two groundbreaking interactive Mobile DTV prototypes that are the first of their kind built in Canada. They were constructed to learn how the rich media content environment associated with ATSC’s Mobile DTV standard actually works. The standard, known as A/153 Part 5 is a new Digital Television standard developed specifically to transmit interactive content to mobile devices. The Ryerson group, comprised of students and staff, dissected the newly published standards papers while building and testing their prototypes up the point of transmission.

To construct the apps the group employed only Open Source and freely available software including experimental server software that duplicates the backend packaging process up to the point of transmission. For content publically available information sources were used to develop a smartphone size Toronto weather application. It reads RSS feeds from Environment Canada and could easily be adapted for use in other Canadian cities. The group is currently constructing a car based Toronto traffic, weather, news and public transit app. The app could receive emergency alerts if programmed and ultimately could react to GPS information if the Mobile DTV reception technology was placed in the appropriate GPS receiving device such as a smartphone.

Ryerson’s ATSC M/H Content Group was formed about two years ago because there was little readily-available information on how to program Interactive content for these emerging open Mobile Digital Television standards. These new standards cross the boundaries between the mobile telephone industry and broadcast television. To share their knowledge Ryerson’s ATSC M/H Content Group publishes the code they develop at so others can learn from it to further develop Interactive applications for the medium.

In addition to the prototype demonstrations in the ATSC TechZone Pavillion, Brad Fortner who is the Program Director, Operations and Technology in Ryerson’s Rogers Communications Centre and ATSC M/H Project Lead will be delivering a paper on the groups work at NAB’s 66th Broadcast Engineering Conference. Titled “Interactive Content Authoring for A/153 ATSC Mobile Digital Television Employing Open Source Tools” the paper is scheduled on Tuesday, April 17th from 1:30 – 2:00 PM in Room S228 in the Las Vegas Convention Centre. For those in the Toronto area and unable to make the presentation Brad will be previewing the paper at the SMPTE Toronto Section meeting on April 10, 2012. Details of how you can attend the Toronto SMPTE Section meeting can be found at

Location: ATSC TechZone Pavilion Booth Number N4039 (North Hall)

XSL and SVG Code For Current Working Weather Prototype (Prototype 114) Now Available For Download

The download (in a zip file) of the XSL code and the SVG file for the Weather App of prototype 114 has been posted to download area.

In order for the Prototype 114 XSLT App to work it must be first transformed using the RSS feed listed on Line 16 of the code. The XSL code should work for any Canadian City using the RSS feeds found at This Prototype (prototype 114) has the appropriate working ECMAScript handlers that are compliant with the SVG Tiny 1.2 standard. It’s SVG file has also been tested by as a packaged DIMS stream via GPAC with successful interactivity displayed on GPAC’s OSMOS4 player (browser).

We believe the SVG file to be SVG Tiny 1.2 compliant. When unzipped it will playback properly using Opera 11.60 as well as GPAC’s OSMOS4 player and playback the weather information based on March 18, 2012. It can also be used for DIMS packaging using GPAC as it has been tested by our group and all functions work when streamed to GPAC’s OSMOS4 player.

The code base for both versions contains weather icon fragments that were created by Emilie Rollandin at the Open Clipart Library. The XSLT code contains information on how the application was written as well as links to further information for study. If you want to learn how to program your own applications open the XSLT file and you’ll find many comments that explain how the application was programmed.
