Recent broadcasts during the Scottish Referendum from the Shetland Islands are excellent example of how IP can be used to deliver broadcast-quality live or recorded material.

IBC 2014 (4.A61h) – Saeta TV Channel 10 Uruguay has selected Open Broadcast Encoder (OBE) for its national ISDB-T platform. OBE is used to encode HD MPEG-4/AVC services compliant with the ISDB-T standard as used in Latin America. A further 15 channels throughout Uruguay will also be using OBE as part of systems integration work by the local team who delivered the encoding platform for Saeta TV.


IBC, Amsterdam (4.A61h): “Low bitrate, low latency, high quality – pick two” sums up the current state of audio codecs for broadcast contribution. A demo of Opus at IBC aims to show that you can now have all three. Opus is a low-delay, royalty-free audio codec designed for a wide range of audio applications and is used in Skype, WebRTC and on the Playstation 4. A specification for using Opus in a standard MPEG Transport Stream was recently written meaning it could be used in broadcast contribution for the first time.

The IBC demo will show a live 1080i feed from a camera going into a 1/2U OBE C-100 encoder, encoded as high bitrate H.264 video and low bitrate Opus audio in an MPEG Transport Stream and into a 1U OBE C-100 decoder with an end to end latency of around 300ms.

The Opus in MPEG-TS standard is published freely online and is available for all manufacturers to implement without royalties.

IBC 2014 (4.A61h) – B1 TV, a privately held news and current affairs channel airing across Romania has selected Open Broadcast Encoder (OBE) for its upgrade from MPEG-2 to MPEG-4/AVC. Having run OBE as a backup encoder from January 2014, B1 decided in March 2014 to reverse the roles and use OBE for its main encoding solution.

“There were two important reasons for our decision,” said Dan Lita, technical consultant for B1. “The first was the picture quality which was better than our previous encoder and secondly OBE resolved compatibility issues with set-top-boxes of a DTH provider. Prior to our main deployment, we had been using OBE for various contribution feeds since 2012.”

IBC 2013 (4.A61g) – Audio Visual Global J.S.C (AVG) which owns An Vien Television has selected Open Broadcast Encoder (OBE) to upgrade their DTH and DTT services. AVG uses OBE to encode its MPEG-4/AVC Direct to Home (DTH) satellite and Digital Terrestrial Television (DTT) services as well as for head-end contribution encoding.

AVG Television’s deployment of OBE is one of the largest deployments of software DVB encoders for DTH and DTT encoding. OBE gives AVG a cost-effective platform with unrivalled flexibility and stability whilst at the same time future-proof. AVG were also able to customise OBE to meet market-specific needs, something not possible with proprietary competitors. OBE allowed AVG to increase its channel portfolio, allowing greater choice for customers.

IBC 2013 (4.A61g) – Icelandic Broadcasters have deployed Open Broadcast Encoder (OBE), a professional DVB encoder, usable on commodity hardware and open source, in a variety of contribution and distribution roles.
