Intertrust Introduces Wasabi Express, a Standards-based DRM Platform for DASH/HLS Mobile and Desktop Applications [PR] | Next Generation Video Delivery System scoops by konnoy | Scoop.it

Intertrust Technologies Corporation today released Wasabi Express, a standards-based next generation DRM platform for mobile and desktop applications. Wasabi Express together with the Company’s DRM Cloud Services provides a single solution for service providers that want to distribute content using a Marlin DRM-compliant media player.

 

Service providers, technology solutions providers and developers using Wasabi Express will have access to technologies that enable them to implement new content distribution business models for delivering over-the-top content to mobile and PC platforms. Wasabi Express offers extensive support for download and adaptive streaming media distribution models (including MPEG-DASH and HLS). It also enables content portability and compatibility with other Marlin clients and services.

 

Wasabi Express is protected by tamper resistance technology from Intertrust’s whiteCryption subsidiary.

How to build a Netflix-like multiscreen OTT service (part 2) : panorama of available technical solutions

How to build a Netflix-like multiscreen OTT service (part 2) : panorama of available technical solutions | Next Generation Video Delivery System scoops by konnoy | Scoop.it

Now that you intensively crawled through part 1 of this blog-post and asked yourself all the right questions intended to avoid common OTT-traps, we can safely presume that you are ready to spend some (or a lot of) time and money on launching your own multiscreen OTT service. So it’s definitely time to choose your bricks, mortar and trowels...

 

As multiscreen OTT/TV Everywhere offers do proliferate while each video tradeshow approaches and connected devices multiply, it’s difficult to monitor all of them and get a 100% accurate idea on who’s got the best offer. Basically your ideal technical partner will most likely be a unique target depending on your background (telco/content owner/TV channel…), your needs (target devices, business models, time to market…), your workflow constraints (CMS, billing, deployed transcoding engines, already deployed apps…) and your budget. Nevertheless, what I tried to do first is to isolate a list of actors whose offer is end-to-end and sufficiently versatile to cover the most common use cases and devices, then provide a complementary list with actors who provide less information but are also known in this market, and then wrap up the post with a bunch of ideas on how you could DoItYourself with less integrated/locking-in solutions. This way, you will end-up with a complete panorama of available technical solutions in mind.

Using Scalable Video Coding for Dynamic Adaptive Streaming over HTTP in Mobile Environments

Using Scalable Video Coding for Dynamic Adaptive Streaming over HTTP in Mobile Environments | Next Generation Video Delivery System scoops by konnoy | Scoop.it

"Dynamic Adaptive Streaming over HTTP (DASH) is a convenient approach to transfer videos in an adaptive and dynamic way to the user. As a consequence, this system provides high bandwidth flexibility and is especially suitable for mobile use cases where the bandwidth variations are tremendous. In this paper we have integrated the Scalable Video Coding (SVC) extensions of the Advanced Video Coding (AVC) standard into the recently ratified MPEG-DASH standard."

Intéressant mais sur le slide 11 de comparaison il y aurait des question à poser.

Notamment le ressenti du client, qu'est ce qui est le plus intéressant :
-Une qualité quasi constante avec la solution Apple (seulement 7 switch)
-Une qualité variable mais "en moyenne" supérieure (DASH + SVC 107 switch soit plus d'un par minute) ?

Comment visuellement ce traduit ces switch, les pics haut, les pics bas ?

Quel est le gain de qualité visuel entre un débit moyen à 1162kbps et 2738kbps ?
