Introduction
This manual covers the following products:
 The B264 openGear® H.264 SD/HD single and dual-channel encoder card
 The B264 standalone H.264 SD/HD single and dual-channel encoder appliance
Both products have the same set of features, and essentially the same user interface. Unless
specifically indicated, all features and controls described in this manual apply to all products.
The encoders have the following features:
 Video Encoding support: up to two channels of SD or HD H.264 encoding, with a
maximum resolution of 19201080p60 per channel.
 Audio Encoding support: up to two channels of MPEG-1 Layer II or AAC-LC, and up to
two additional channels of MPEG-1 Layer II.
 Video Inputs: support for composite, SD-SDI, HD-SDI, and 3G-SDI.
 Audio Inputs: support for balanced or unbalanced analog audio, and SDI embedded
digital audio.
 Outputs: 2 ASI ports and 2 Ethernet ports, supporting 100 Mb/s and 1 Gb/s operation.
 Replication: each UDP or RTPencoded stream can be replicated on both ASI ports and 4
times on each Ethernet port.
 Support for UDP/RTP on Ethernet.
 Support for Over-The-Top (OTT) protocols: HTTP Live Streaming, RTMP, Direct HTTP.
 Support for SMPTE 2022 FEC on Ethernet.
 Closed-Captioning support (both EIA-608 and EIA-708 captions).
 AFD extraction and insertion support.
 Support for pre-compressed Dolby AC-3 pass-through embedded in SDI inputs.
 Support for SCTE-104 to SCTE 35 conversion.
 Multiplexing support: each output can be configured to carry either encoder as a Single
Program Transport Stream (SPTS), or both encoders as a Multi Program Transport
Stream (MPTS).
The B264 encoder includes two additional Ethernet ports for control and management.
Typical application scenarios for the B264 are:
 Contribution and Distribution
 Video Distribution over IP backbones
 IPTV headends
 OB Vans
 High-Quality OTT generation
