Signal Processing
The Messenger 2 Transmitter Enhanced (M2TE) series accepts up to two Standard Definition (SD) or
High Definition (HD) 4:2:2 digital videos or analog SD videos and analog stereo audio inputs (Mic or
Line level). Each video is compressed independently according to the Advanced Video Compression
(AVC) /h.264 specifications. Therefore, the video inputs can either the same resolution and frame
rate or completely different resolutions and frame rates. The low-latency AVC Encoder supports the
Baseline Profiles with resolutions from 480 to 1080 with support for either interlaced or progressive
formats. The audio is compressed using MPEG layer II compression. Low rate Auxiliary data up to
115 KBaud can be optionally supported.
The basic system supplies support for generation of a single audio/video/data program within a
MPEG Transport Steam (TS). The audio, video and auxiliary
data packets PES streams are multiplexed
with basic service data to indicate the service name. The stream can be scrambled with AES
scrambling system to provide protection in sensitive applications.
The dual system option supplies support for generation of two independent audio/video/data
programs within a single MPEG Transport Steam (TS). The dual program stream can also be
scrambled with AES scrambling system to provide protection in sensitive applications.
The M2TE can operate in one of two modes When the Transmit Mode is enabled the TS will be sent
to the COFDM RF transmission processing section. In this mode it can also be streamed out
optionally the ASI output port and/or the LAN port for local distribution or recording on external
