EH244-Q IP Platform


Multiplexing Encoder Host with QAM and IP Output

The EH244-Q IP Encoder Host Chassis is an ideal platform for MPEG-2 or MPEG-4/H.264 video encoding needs due to its many flexible and configurable output options. The platform is designed with a total of 6 input bays and an internal multiplexer that allows the user to construct custom program multiplexes and output them in RF QAM or IP.

The EH244 platform is designed to house any combination of Drake’s popular HD or SD encoder modules, including the SDE24A, HDE24A, and SDI24A. The EH244-Q IP model includes:

QAM: An integrated Quad QAM modulator provides four bonded 6MHz RF QAM channels that are frequency agile in 24MHz blocks based on the first selected channel. One or more encoded streams may be distributed to each of the 4 QAM channels based on bandwidth requirements, SD and MPEG 4 H.264 content require the least amount of bandwidth so multiple programs can be multiplexed on a single QAM channel as long as the maximum data rate for the selected QAM rate is not exceeded. For example, 38.8 MB/s is the maximum data rate for 256QAM a popular choice for many customers. MPEG2 HD programs require the most bandwidth so users may choose to limit each QAM channel to only one or two programs. Any unused QAM channels may be disabled during setup and that channel may be reused for other content.

IP: An additional RJ-45 port provides IP encapsulate content from each of the encoder modules (up to 12 programs if using SDE24A modules or six programs if using HDE24A or SDI24A modules) in a Multicast of SPTS or MPTS streams as selected by the user.
