Who said the economy was bad?
hasn't shown any indication that the economy is slowing its engineers, who have come to the NAB 2009 Show with 28 (count 'em!) new products.
I got a chance to see a demo of one of those products — the Avenue 4500 MPEG transport stream processor.
The 4500 can be used for translating DVB-ASI to SMPTE 310M in broadcast transport applications. The system is used with both DVB-ASI and SMPTE 310M bit streams. As a converter, it can translate ASI to 310M or 310M to ASI. Using the reference input, the output bit stream can be synchronized to a video or 10MHz reference signal.
“Verifying the health of a 310M stream can be a challenge but we have a convenient, affordable way for broadcasters to check PIDs and PMTs for all of their transport streams," said Mondae Hott, director of sales for Ensemble Designs.
The built-in transport stream analyzer detects whether the input constitutes a valid signal by checking for PAT, PMT and PID packets. In addition to the ETR 290 test protocols for both Priorities 1 and 2, the user can configure tests to define the minimum number of video and audio packets expected per second in a given service. Alarms can be generated via SNMP, Avenue PC, and contact closure outputs.
Other products on display will include new Avenue HD/SD/3G electrical and optical converters, HD/SD/3G distribution amplifiers, and an HD video protection switch used for critical feeds in satellite and broadcast.
