DVB and HbbTV Release New DASH Validation Tool to Simplify Content Conformance

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 and HbbTV have a close relationship and common membership, making this the perfect partnership,” said Peter MacAvock, chair of DVB. “Content delivery is becoming increasingly complex. Working together, we are bringing simplicity to content conformance for DASH-delivered streams.”

Extending the existing DASH-IF validator, the new tool includes:

  • Comprehensive checks for MPEG-DASH MPD validation (XML, DASH schema, and MPEG-DASH MPD rules), segment validation (ISO BMFF and MPEG-DASH segment rules), cross-representation validation (MPEG-DASH cross-representation rules), and live MPD segment access validation.
  • Compliance with a wide range of specifications.
  • Support for DVB-DASH Profile v1.1.1 and HbbTV 1.5 extensions.

After performing conformance checks, the new tool generates reports for users to analyse. The reports are colour-coded, making it easy to see important information, warnings, and error messages. Additionally, the tool complements the HbbTV Association DRM Reference Application and Test Suite, providing device manufacturers with examples of working applications and content with DRM.

“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,” said Vincent Grivet, chair of the HbbTV Association.

DVB-DASH defines the delivery of live and on-demand TV content over the open internet via HTTP adaptive streaming. By defining additional constraints and referencing a selection of video and audio codecs from the DVB toolbox as being technically appropriate for use with MPEG-DASH, DVB-DASH facilitates implementation of the MPEG-DASH specification. DVB-DASH is referenced in the HbbTV specifications, which means that many devices on the market currently support this profile. Content providers across Europe have deployed services using DVB-DASH.

The validator source code is now available for free under an open source license and can be found by visiting https://github.com/Dash-Industry-Forum/Conformance-Software.

TNDV Destination Packs Big HD Mobile Production Capabilities into Agile, Medium-sized Truck

As the newest addition to TNDV: Television’s fleet of nine full-service mobile video units, Destination packs full-sized production truck capabilities—including all the bells and whistles high-end clients expect—into a more agile, compact 40-foot vehicle that can maneuver in the most space-challenged venues.

TNDV_Destination_Venue

“While there are plenty of full-sized HD production trucks on the road today, there aren’t many that can fit backstage or in the alley behind the venue,” said TNDV President and Owner Nic Dugger. “By offering the same firepower in a much smaller footprint, Destination definitely fills that void in this specialized, niche market.”

Before joining TNDV’s fleet, the truck, originally known as Blackjack, had crossed the continent over the years as it changed hands between three different owners: ProShow in Vancouver, Greystone Media in Portland, and finally TNDV. Upon acquiring the truck, TNDV moved Blackjack to Atlanta, where it was stationed outside the Philips Arena (now State Farm Arena) for four years. As a part of the TNDV fleet, the truck was used to produce all Atlanta Hawks’ home basketball games.

TNDV upgraded and rebranded the medium-sized truck after fulfilling its service at the arena. Now called Destination, the truck is built to integrate with TNDV’s remaining eight video and audio trucks. The name also recognizes the truck’s long journey to its final home in Nashville.

“In light of the growing demand for compact HD production trucks for live sports and entertainment, music festivals and concerts, we completely re-engineered the truck’s interior with a robust infrastructure capable of handling a high density of video and audio feeds,” Dugger said. Destination is well-equipped to handle all types of live events, such as music festivals and concerts, college and high school sports, Red Carpet shows, and interviews with athletes and celebrities. It can also accompany our full-sized, flagship trucks whenever they are sent to cover major network television events, such as live sports, awards shows, and music specials. For large-scale music events, we can switch multiple outputs from within the truck, and for sports, there’s an unusually large 3 M/E production switcher for what is considered a smaller truck.”

Destination Infrastructure

With expanding sides that increase the truck’s width from 9 to 11.5 feet, Destination’s unique interior includes a main video area, an audio suite, and an isolated video production area that allows producers and editors to work on content without disrupting live shows.

In the main production space, a Ross Carbonite 3 M/E production switcher—capable of supporting a live multi-camera workflow—faces a large multiviewer monitor wall. The truck also offers an array of high-end digital video effects (DVEs) and live broadcast graphics options, including two Ross xPression dual-channel CG systems, and either a Chyron Duet Hyper X3 or Pinnacle Deko 3000 dual-channel live graphics system. Programs can be recorded onto a bank of Aja KiPro digital disc recorders, and optionally, either Sony 1800 HDCam or Panasonic AJ-HD1200A VTRs. An EVS 6-channel HD XT[2] slo-mo system provides an added benefit for live sports production.

For acquisition, Destination carries a complement of Hitachi SK-HD1200 portable HD studio/field production cameras which, with their three 2.3-megapixel ultra-advanced CCDs, produce a high dynamic range (HDR) 1080p picture with low noise. The truck’s audio suite features a Soundcraft Si Impact 32 fader digital audio mixer with a Soundcraft MADI stagebox. Video and multiviewer routing are handled by a large Platinum router from Imagine Communications.

“While the truck is compact, there’s plenty of room to accommodate any needs our clients may have for separate workspaces,” he added. “We even have a kitchenette with a fridge and dining area, among other conveniences, to support the crews during long work hours.”

LynTec Power Control Selected for Pennsylvania’s The Hill School

LynTec announced that integration company Starlite installed LynTec’s RPC remote control breaker panel at The Hill School’s Center for the Arts (CFTA) in Pottstown, Pennsylvania. The panel replaced two 30-year-old dimming racks with an 84-circuit RPC panel, providing the school with reliable and efficient power control for the theatre’s house and stage lighting systems.

“When the school decided to upgrade its theatre lighting to LEDs, we knew we had to take a close look at the power system in order to reap all the efficiency and cost-saving benefits that LEDs provide,” said Brandon Creel, ETCP, CTS-D, director of engineering at Starlite. “LynTec is our go-to power control provider because the company delivers a budget-friendly and user-friendly solution that cuts out all of the headaches that aging power infrastructures can pose. For The Hill School, it’s also been a great way to teach theatre students how to run a show production using modern power control.”

Built in 1987, the 31,000-square-foot visual and performing arts center houses the Center Theatre, a 700-seat proscenium theatre that serves as a learning laboratory for budding actors and actresses, scenic and lighting designers, and theatre technicians. The power control for the stage lighting system hadn’t been updated since the theatre was built and was due for an overhaul. In the first phase of the project, Starlite replaced the theatre’s two outdated dimming systems with LynTec’s RPC remote control breaker panel along with a slave panel to allow students and staff to remotely and efficiently control, monitor, and switch its new LED lighting. In the second phase of the project, Starlite incorporated the theatre’s house and work lighting into the system, giving it a centralized on/off control. With the installation, the facility went from 288 circuits to 84 circuits, freeing up 100-amp three-phase service from one of the existing panels that had been at capacity. Now the school has room to address other needs, such as a company switch and future facility expansion.

The system is accessible from any web-enabled device, allowing users to control it remotely. The result is greater installation flexibility, more efficient power control, and the ability to provide direct on/off control for LED lighting. The panelboards also enable built-in under- and over-voltage protection, optional customizable sequential circuit level on/off capabilities, and the ability to interface with third-party control systems via contact closure, TCP/IP, DMX, or RS-232.

“Up until five years ago, power control was an afterthought to lighting installations, but as LEDs have become ubiquitous, power control is now a critical component to preserving the long lifespan and efficiency of an organization’s lighting investment,” said Mark Bishop, president of LynTec. “The Hill School is an excellent example of how our power control solutions eliminate all of the hurdles that come with retrofit installations. We’re honored to take the stage with such a prestigious institution.”
