Divx decrypter12/7/2022 ![]() ![]() ![]() These video frames are encrypted using a set of common key(s).it contains both encrypted as well as non-encrypted portions). Each of the alternative streams includes partially encrypted video frames (i.e.Each of the alternative streams is stored in a separate container file referenced by a top-level index file. Obtaining a top-level index file that identifies a plurality of alternative streams of a protected video.Here’s a quick rundown of what it covers: streams that encode the same media content in different ways) on a playback device. If I outline the patent, it discusses a method for playing back the protected content from a plurality of alternative streams (i.e. I’ve simplified it, but TBH, there’s a lot that happens in ABS. This happens because of Adaptive Bitrate Streaming. You might have noticed how the quality of a YouTube video changes with the speed of your Internet. To give you a basic background, ABS is a streaming technique where the streaming platform first analyses a user’s network speed and CPU power and adjust the quality of the streaming video accordingly. Click here to read what we think of that patent.įor this analysis, I picked one of the DivX’s patent related to Adaptive Bitrate Streaming (ABS). The patent was involved in litigation against Google, Qualcomm, Samsung, and 7 more companies, filed by Dynamic Data Technologies. In my last preliminary analysis to understand the validity of the patent, I tested a patent related to motion vector estimation in video encoding. Another reason I decided to analyze patents involved in this case is that we are lately working a lot in the video technology domain. Netflix, Hulu, and Divx – all these companies are big names in their domain and it seemed like a great case to run our patent strength check on. Netflix directly infringes the DivX Patents by making, using, offering to sell, selling, and/or importing into the United States internet video streaming technology, software, and services that practice the inventions claimed in the DivX Patents. According to them: “DivX patents disclose technologies that enable many benefits, including receipt and playback of streaming digital video on a wide variety of consumer electronic devices high-quality video playback, including 4K high-resolution video, without stalls robust and efficient DRM and features that improve user experience, including trick play and fast start”. In its complaint, DivX has argued that Netflix and Hulu are infringing their 8 and 7 patents respectively. Technologies related to video processing, storage, and streaming are the most important innovation areas for these companies and it is not surprising to witness patent litigations in these areas. Now, as video-on-demand services like Netflix, Hulu, Prime videos, and HBO, are becoming increasingly popular, the video technology industry is bound to see increased competition. In its history of 19 years, DivX has been in multiple mergers and acquisitions and has made multiple headlines with their innovations in video technology. On March 5 this year, DivX LLC again made it to the headline, as it asserted a patent lawsuit against Hulu and Netflix for infringing their multiple video compression, encryption, and streaming patents.ĭivX is easily one of the most famous names in video technology domain with over 1 billion devices licensing their video processing and encoding technology globally. ![]()
