Connection Setup Guide
xCoder is controlled from a web based interface. xCoder comes with a separate setup guide. Refer to
the setup guide if you are installing a new xCoder machine.
Operation Overview
xCoder is composed of 3 separate functional components as shown in the diagram below. Each
functional block has separate configuration and control for maximum flexibility. In a given processing
flow, any combination of these 3 functional blocks may or may not be in use.
The 3 blocks are as follows
1. Splitter: This block provides a mechanism to split incoming ASI or IP based MPEG2-TS streams
and re-route them, or the individual programs in a MPTS. For example, a MPTS with 4 programs
in it, can be split into 4 separate SPTS MPEG2-TS steams which can be processed and/or
passthrough the xCoder platform.
2. Media Processing Engine (MPE): The MPE provides the video and audio processing functions
required for applications such as decoding, encoding, transcoding and format conversion. In
addition, AES scrambling, logo insertion, and a plethora of other media processing functions are
available in the MPE.
3. Mux: The Mux can passthrough and/or merge SPTS streams into MPTS streams. For example,
4 different SPTS MPEG2-TS streams created by the MPE can be combined into 1 MPTS
MPEG2-TS stream here.
Each processing block can route output signals to the neighboring blocks for further processing. It is
possible to loop a single media stream multiple times through the system if needed.
