Product Overview 
The B264 supports up to two H.264 SD/HD encoders, with up to four stereo pairs of audio 
encoding. One stereo pair is dedicated to each video encoder, and the remaining two stereo pairs 
can be individually associated with either channel. The encoded transport stream can be routed 
and replicated to Ethernet and ASI outputs. Both SPTS and MPTS outputs are supported. 
The following inputs are available: 
  Software-configurable Composite or SDI video inputs, with auto-detection capability 
  SDI video inputs support SD-SDI, HD-SDI and 3G-SDI, with auto-detection capability 
  Analog unbalanced audio stereo inputs 
  SDI embedded audio support 
  Two internal test packet generators (which can be used to generate ASI or IP test 
streams) 
The following outputs are available: 
  Two ASI outputs 
  Two Ethernet outputs, supporting full-duplex 100 Mb/s and 1 Gb/s operation 
Each of the encoder channels in the B264 can operate in one of two modes: 
  ASI/IP Streaming: used in traditional broadcast applications. The encoded bitstream be 
transmitted over ASI or IP using UDP/RTP protocols, with replication capability. 
  OTT Protocols: used for Internet streaming. These include RTMP, HLS and Direct 
HTTP. For the modular B264, the control port can be used for stream output in these 
modes. 
ASI/IP Streaming 
For ASI/IP streaming, configuring the B264 includes the following steps: 
Step 1: Configure the encoders. 
Step 2: Configure the outputs (ASI or IP). 
Step 3: Make connections between inputs and outputs (for UDP and RTP). 
The connections between inputs and outputs can be made as part of the input or output 
configuration steps. The B264 supports many-to-many connections. 
The overall architecture is depicted below.
