Appear TV will be showcasing updates to its multi-functional X-Series platform at its stand 1M2-01, BroadcastAsia 2019, Singapore.
The X10 and X20 support digital video broadcasting satellite (DVB-S2x) systems and digital satellite newsgathering (DSNG) with a new S2x contribution modulator and demodulator.
The company will also highlight how its X20 platform is suitable for low-latency video-assisted referee (VAR) applications.
The X-Series (X10/X20) offers the complete spectrum of encoding codecs and helps broadcasters adopt the many benefits of an IP-centric operation in their own timeframe. The modulator also has an RF input that can be connected to a backup transponder, which can then be routed to the main output in case of a hardware failure on the main transponder. The X10 and X20 can each output two transponders featuring switchable L-band or Intermediate Frequency (IF) with 72 Mbaud bandwidth.
In addition to the new modulator, the X-Series also features update in its hardware design for its DVB-S2x contribution demodulator, a platform that supports the DVB-S2x DSNG and professional services profiles. It can demodulate four transponders from four RF inputs, with up to 64 MBaud bandwidth, while fixed-key AES-128 and BISS-descrambling are embedded into both the modulator and demodulator.
Appear TV’s X20 is suitable for VAR as it fulfils all the requirements of this application. With its offering of channel density and ability to combine encoding and decoding of multiple contribution formats in the same chassis, the X-Series promises high quality in a redundant architecture to ensure the strongest availability of video. The need for high-quality video with low latency is crucial for the referees to verify calls made on the field. With the X-Series, content can be sent to the referee monitors immediately following capture, allowing them to make the right call and not hold up gameplay.
Appear’s X20 contribution links are currently being deployed in OB vans covering top football leagues throughout Europe and Asia. A single X20 chassis encodes more than 20 signals with low latency before being encapsulated to IP and sent to the video operation room (VOR). At the reception site, the X20 system decodes the signals for further analysis. Some of these signals are then encoded in the same chassis and sent back to the OB vans. This VAR solution is also suitable – for UHD, SDI-over-IP and more – and can be adapted to customers’ specific needs.
