Cable Television Laboratories published new testing procedures to verify compatibility of devices with multistream CableCards, referred to as M-Cards.
CableLabs said it will begin offering verification testing of plug-and-play devices like digital-video recorders with the multistream interface beginning in January as part of CableLabs Certification Wave 49. The M-Card project is supported by TiVo, Motorola, Digeo, Solekai, Digital Keystone and ViXS.
The M-Card interface is designed to allow multiple digital-video streams to be decrypted simultaneously, allowing a subscriber to view one channel while recording another, without requiring multiple, separate cards. DVRs are expected to be the first devices to use the multistream interface.
