7 9223-OM (V2.0)

Introduction

The 9223 is an advanced openGear™ H.264 SD/HD dual-channel encoder, with the following

features:

• Video Inputs: support for composite, SD-SDI, HD-SDI, and 3G-SDI.

• Audio Inputs: support for 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 encoded 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.

• Audio Encoding support: MPEG-1 Layer II and AAC-LC.

• Support for pre-compressed Dolby AC-3 pass-through embedded in SDI inputs.

• Support for secondary audio (dual-channel board required).

• Muxing 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).

Typical application scenarios for the 9223 are:

• Contribution and Distribution.

• Video Distribution over IP backbones.

• IPTV headends.

• Monitoring

• High-Quality OTT generation

Product Overview

The 9223 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

• SDI video inputs support SD-SDI, HD-SDI and 3G-SDI

• 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)
