3Overview
The Kramer VM-2HDCPis an HDCP (High-Bandwidth Digital Content Protection)1 compatible 1:2 distribution amplifier for DVI-D (Digital) signals. Since high-resolution DVI signals are very sensitive to cable quality and to PCB layout, the VM-2HDCPuses a uniquely designed PCB which includes all buffering, conditioning and amplifying circuitry to provide two high-level output signals.
In particular, the VM-2HDCP:
•Distributes signals having resolutions up to UXGA, including all HDTV formats
•Has a bandwidth of 1.65GHz
•Supports the DDWG DVI 1.0 standard
•Consists of a built-in re-clocking block that re-generates the DVI signal, so that several units may be cascaded
•Can read and store, in non-volatile memory, the EDID2 block from one of the outputs, so it can then provide the EDID information to the DVI source even if the display device is not connected
•Has I-EDIDPro™ Kramer Intelligent EDID Processing™, an intelligent EDID handling and processing algorithm that ensures Plug and Play operation for DVI systems
•Has three DVI-I connectors, which are compatible with all types of DVI cables
•Is a cost-effective solution for distributing the TMDS signals used for DVI, and uses state-of-the-art line drivers on both outputs
3.1About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard3, protects digital video and audio signals transmitted over DVI or HDMI connections between two HDCP-enabled devices to eliminate the reproduction of copyrighted material. To protect copyright holders (such as movie studios) from having their programs copied and shared, the HDCP standard provides for the secure and encrypted transmission of digital signals.
