Jitter Box IP/IP™
Real time, 1 RU, standards compliant, Linux® based, web manageable, multistream, IP PCR (Program Clock Reference) Jitter correcting appliance designed to correct any type of packet jitter. Will fix jitter so you can stream video to PCR timing sensitive video devices. VoIP platforms face similar packet jitter issues. Poor voice quality is the result. This device also fixes audio jitter.
Jitter is inevitable in all digital transmissions. Well designed transmission equipment can tolerate some jitter. Excessive jitter overwhelms most routers. Both video and audio streams are affected by jitter. Jitter manifests itself via video artifacts and audio jitter causes audio artifacts.
MPEG transport streams have become the de facto video media transport via IP. However, many IP transport streams are asynchronous, which makes them prone to jitter when they are sent to PCR compliant devices. The Jitter Box IP/IP corrects PCR from non PCR standard IP stream formats like HLS or RTMP. PCR timing compliant transport streams are essential for streaming transport streams to sensitive devices such as modulators, muxers, decoders, and encapsulators.
Audio packets utilize less bandwidth but are equally troublesome. Audio jitter plagues VoIP platforms and results in audio breakup. Appliances like the Jitter Box IP/IP or DOZER™ are needed to fix audio that travels long hops.
This product "came to be" since DVEO equipment has had to interoperate with Harmonic®, Ericsson®, Cisco®, and Arris™ video equipment. We had to develop world class techniques to survive.
- Guarantees improved real-time video or voice over IP transport
- Inputs/Outputs: 2 each Gig/E ports
- Input: One GigE IP input (H.264, MPEG-2, or optional H.265) – UDP, RTP, RTSP, HTTP, HTTP Live, RTMP (pushed from Flash server)
