Open Broadcast Systems Adds Subtitle Overlay Support To Decoders

Open Broadcast Systems has added support for overlaying teletext subtitles with its C-100 and C-200 decoders. This enables users to cost-effectively monitor teletext subtitling, including on professional 4:2:2 video streams.

Kieran Kunhya, CEO, Open Broadcast Systems, commented: “Monitoring contribution streams can be complex and expensive, especially when dealing with multiple languages and subtitle tracks. By adding support to our decoders, we are allowing flexible and cost-effective monitoring without losing any of the accuracy needed for professional quality video streams.”

Operators can monitor transport streams in multiple languages using the C-100 or C-200 decoder. It can be used in both dense deployments with many channels monitored on a single server, as well as being suitable for small scale single channel deployments. The company’s small form-factor decoders can be attached to the back of a monitor without the need for investment in full sized hardware.

The C-100 encoder and decoder supports high-quality, low-latency news, sport and channel contribution. It allows flexible deployment of contribution services in pure software or on a wide variety of high-density chassis.

The C-200 encoder and decoder delivers ultra-high value in pristine quality and with very low end-to-end latency. The C200 Decoder is capable of decoding MPEG-TS to 2022-6 and 2110 Uncompressed IP, using software running on COTS hardware.
