New version of Elecard CodecWorks with improved multiplexing and backup mechanism is out

Elecard CodecWorks version 4.7 for Windows and Linux is officially out. Major improvements are related to product setup and configuration. The Linux version is enriched with a number of new features, available exclusively for Windows OS version up to now. 

Improvements and new features to both Windows and Linux versions: 

• support for SRT protocol in caller/listener mode is added;
• the server redundancy system is improved. Now the redundancy is configured on a single server and further deployed to the group of backup servers automatically;
• automatic configuration update of encoded streams on redundancy servers within predefined time interval is implemented; 
• fault-tolerant architecture is updated which made the software more stable; 
• SPTS/MPTS multiplexing system is updated to ensure consistent bitrate for output channels;
• folder selection for log files recording is added;
• EIT/SDT/NIT/TDT table pass through, including those incoming from a separate source, is implemented. Now the stream is multiplexed along with EPG data;
• processing of SMPTE-TT teletext and OP42/47 VANC of SDI area is implemented; 
• minor bugs are fixed.

New features in CodecWorks for Linux (CentOS 7.4-7.8):

• the script for automatic driver installation for Intel GPU is implemented;
• SNMP alerts are added;
• packetizing and broadcasting via MPEG-DASH is implemented;
• the CBG mechanism is implemented;
• the internal system of responses to changes in input stream characteristics is improved. The basic response scenarios are as follows:
  • color Bar Generation initiates or custom screen is shown if the main source becomes unavailable or other specified criteria are met;
  • switching to redundant source if the main source becomes unavailable or other specified criteria are met 
  • encoding schema is rebuilt if the input stream characteristics change.
• the mechanism for stream source redundancy is revised. Now there is an option to switch back to a main source or keep using a redundant source when the main source is restored;
• distributed transcoding is implemented. Now the Linux version supports HEVC 4K transcoding on high density servers.
