The DVB and the HbbTV Association have created a new DASH validation tool to simplify content conformance for application developers and content providers working on the IP delivery of live and on-demand TV content via HTTP adaptive streaming. 

According to the DVB, the newly released tool conducts checks of ISO/IEC 23009-1 MPEG-DASH media presentation descriptions (MPDs) and segments to ensure conformance with DASH-related specifications from DVB and HbbTV.

DVB chair Peter MacAvock said that the consortium’s “close relationship and common membership” with HbbTV made this “the perfect partnership”. 

He added: "Content delivery is becoming increasingly complex. Working together, we are bringing simplicity to content conformance for DASH-delivered streams.”

Features of the new tool include comprehensive checks for MPEG-DASH MPD validation; segment validation; cross-representation validation and live MPD segment access validation

After performing conformance checks, the new tool claims to generate reports for users to analyse. 

The DVB claims that the tools also complement the HbbTV Association’s DRM Reference Application and Test Suite, providing device manufacturers with examples of working applications and content with DRM.

Vincent Grivet, chair of the HbbTV Association said: "We are excited about the release of this DASH validation tool, which will help application developers and content providers verify that their services are compliant with the HbbTV/DVB DASH profiles, enabling them to offer compelling hybrid services that enhance the viewer experience.”

The tool’s source code is now available for free under an open source license.
