06 NAB Product Review: Signal Proceing

Television is now poised to transition to the world of ultra-high definition, high dynamic range, extended color gamut, coupled with the move to the all-IP television plant where this beautifully detailed content is generated and made ready for delivery to the viewer. But no matter how sophisticated the creation and delivery portions of the video chain become, there's one element that isn't going to change and that's the need for signal processing. Based on the amount and depth of signal processing gear on display at the 2016 NAB Show, manufacturers have their collective fingers on the industry's pulse and are ready for just about any conceivable requirement.

EAS/CAP

Digital Alert Systems demonstrated integration of its DASDEC Emergency Alert System messaging platform with SAM's ICE channel-in-a-box automated playout technology. The collaboration has resulted in a simpler approach to messaging and smoother flow of emergency information. The company also announced a partnership with Broadstream to integrate the DASDEC and CAP messaging platform with Broadstream's OASYS playout product.

CLOSED CAPTIONING

Comprompter unveiled a multi-person version of its CC2 closed captioning system. It uses a powerful voice server to convert voice-to-text and can serve up to eight people at a time.

Digital Nirvana introduced its new closed captioning services for broadcast and online videos, which includes post-production roll-up and pop-on captioning services for all technology platforms, as well as caption synchronization conversion to an IP format from broadcast or vice versa. The new closed captioning services can handle multiple SD and HD video formats and a wide range of caption file formats.

EEG spotlighted its first iCap-encoder for encoding closed captions to live production IP video. The new iteration supports compressed MPEG transport streams and uncompressed standards such as ASPEN and VSF TR-03, which both use the SMPTE 2038 standard for ancillary tracks.

Telestream has added closed captioning capabilities of its MacCaption (Mac)/CaptionMaker (Windows) standalone platforms to the company's Vantage Media Processing Platform. Branded as Timed Text Flip, the new module brings integrated closed captioning technology into Telestream's Vantage workflow.

ENCODERS/DECODERS

DVEO showed its InstaView ultra-low delay encoder and decoder set. It provides quality identical to H.264, yet uses significantly less bandwidth and sports a 100ms delay. Also shown was the Futura II ASI+IP SD to 1080i MPEG-2 broadcast encoder.

Digigram premiered two HEVC/H.265-enabled versions of its AQORD video encoder which enable point-to-point broadcast contribution of 4K content to homes.

DTV Innovations demo-ed their Gryphon unit that offers low-latency video encoding for a range of signals including MPEG-4 with 4:2:2 10-bit HD. Gryphon includes an internal modular for DSNG, ENG or other applications and accommodates up to 16 audio channels. Also on display was the Falcon decoder that complements the Gryphon with decoding of MPEG-4 HD video and includes a satellite demodulator.
