The last time I wrote about Downloadable MediaCipher (a precursor to DCAS), I got a question about how Motorola DM compares to Widevine’s downloadable security solution. I’ve done some digging and discovered that the most important difference seems to be the target market. Widevine’s technology is IP-based, while Motorola DM is designed specifically for a more traditional cable network. Sure, MSOs could choose to deploy Widevine’s downloadable solution, but it would require switching to an entirely different network architecture. Seems unlikely.
There is still much I don’t know about Motorola DM (not to mention Widevine’s solution), but I plan to keep asking questions. If you have any to add to the list, leave a comment here.
