OpenCable is a set of specifications created by CableLabs to "Define the next-generation of advanced digital cable-ready devices". OpenCable uses SCTE standards for the video, transport and various interface requirements, but also adds a requirement for a Java based interpreter and an encryption system employing CableCARDs. The goal is to create a common standard for digital cable television within United States, hence promoting competition among licensed device manufacturers. Cable Television Laboratories, Inc. ... The Society of Cable Telecommunications Engineers (SCTE) is an organization that develops training for cable television installers and engineers; in this role it is analogous to the Society of Broadcast Engineers for broadcast television. ... Java is an object-oriented programming language developed by James Gosling and colleagues at Sun Microsystems in the early 1990s. ... In cryptography, encryption is the process of obscuring information to make it unreadable without special knowledge. ... CableCARD is the trademarked term for the Point of Deployment module (POD) defined by standards including SCTE 28, SCTE 41, CEA-679 and others. ...
Digital restrictions management
DRM is implemented using both Java and a pluggable decryption card. This would work much like DirectTV's encryption system. When a crack of the current encryption system in use becomes widespread a new card can be sent out to consumers and a new encryption system employed. Putting portions of the restrictions management in the unsafe Java interpreter allows greater flexibility in billing. Digital Rights Management or Digital Restrictions Management (DRM) is an umbrella term for any of several arrangements which allows a vendor of content in electronic form to control the material and restrict its usage in various ways that can be specified by the vendor. ... This article is about algorithms for encryption and decryption. ... DirecTV is a direct broadcast satellite (DBS) service that broadcasts digital satellite television and audio to households in the United States. ... Software cracking is the modification of software to remove encoded copy prevention. ...
Increased competition
In the current market a cable operator is locked into either Motorola or Scientific Atlanta for 10–20 years when they make the capital investment to use either system for their digital cable operations. With OpenCable a consumer can use a MPEG-2 decoder from either company and the cable company can switch between the system at only the cost of the decryption card for each consumer and the backend costs. The decryption cards will probably license for $10 to $20, much less than the $50 for a simple decoder or $500 for a full featured PVR. Motorola (NYSE: MOT) is a global communications company based in Schaumburg, Illinois, a Chicago suburb. ... Scientific Atlanta is a large manufacturer of cable television, telecommunications, and broadband equipment. ... MPEG-2 (1994) is the designation for a group of coding standards for digital audio and video, agreed upon by MPEG (Moving Pictures Experts Group), and published as the ISO/IEC 13818 international standard. ... It has been suggested that Licensing (strategic alliance) be merged into this article or section. ... PVR can mean Personal video recorder. ...
