As broadcasters gather in Las Vegas to plan their next equipment investment, Korean test and measurement firm ATBIS is introducing two new products designed to support stations who are making investments in next-generation ATSC 3.0 broadcasting.
“Gateways are essential devices for Single Frequency Network applications, and the ATBIS Gateway played an important role in live broadcasts at the recent winter games in South Korea,” said ATBIS CEO Sam Eom. “It’s reliable and can help a broadcaster manage a very complicated ATSC 3.0 implementation.”
ATBIS began operations five years ago with product to serve the digital television marketplace. Since its inception, the company has developed several signal generators and test systems and has tested its latest products at the ATSC PlugFest staged recently in Baltimore.
The ATBIS Gateway can accept several IP data streams from an encoder, multiplexer, signaling server, electronic service guide server, and other devices. The ATBIS Gateway insures proper signaling for broadcast implementations that deploy Single Frequency Networks. The device supports multi sub-frame and Multi PLP functions and is user configurable.
Featuring an 8x Ethernet Gigabit interface for control and data transport, the ATBIS Gateway (model ATS1500) also includes a user-friendly web user interface control and can be used with a standard web browser. The Gateway provides external clock support, L1/L2 (LMT) signal generation support, ALP packetizing support for general IP data input, and can accommodate an ALP-TP/DSTP input stream.
Also on display for NAB Show attendees is an ATBIS ATSC 3.0 Broadcast Measurement & Simulator, AMM Studio.
AMM Studio simulates various configurations of ATSC 3.0. Since it provides users with the desired configuration and modification of an input stream, broadcasters can simulate and test various configurations in the complex ATSC 3.0 spec prior to actual deployment so that they may prevent unexpected broadcast “accidents.”
Receiver manufacturers can also reduce their product development period and cost by using various test patterns of ATSC 3.0 provided by AMM Studio.
The AMM Studio product is already being used by leading consumer electronics companies and it has been certified by Korea Broadcasting Corporation and used for other broadcasting equipment certifications.
Major functions of AMM Studio:
– Live & file input analysis
– Data Modification (Signaling, ESG, etc.)
– PCAP Stream Save / Load
– Multi sub-frame and Multi PLP Add / Delete support
– Support Verification and Validate (V&V) test patterns
– Live RF Output
ATBIS is also showing the ATSC 3.0 Redundancy Switch (model BS1304), which is used to detect signal errors and prevent transmission issues. It supports the ATSC 3.0 standard and analyzes the STL-TP, ALP-TP, and General IP inputs as well as SMPTE2022-1 FEC decoding and encoding functionality to correct packet loss errors in IP Transport.
Both the ATBIS Gateway and ATBIS AMM Studio can be seen this week at the NAB Show, in Booth SU6807.
