Page 7: Introduction
IP network of VN-Matrix encoders and decoders. The ® VNM Recorder is used with any VN-Matrix application to document, archive, review, and play back highly sophisticated or demanding AV imagery. The VNM Recorder has the ability to record PURE3 encoded IP streams on each channel. -
Page 8: Overview Of Recorded Streams
• Each recording may contain up to five channels. Each channel originates from a VN-Matrix encoder device (or a VN-Matrix codec • configured as an encoder). -
Page 9: About Raid5 Storage
Transport Protocols Used for Streaming The source data from a VN-Matrix encoder can be distributed to multiple displays/decoders (one-to-many) or to a single display/decoder (point-to-point). A previously recorded stream can be distributed in the same way and may be thought of as an encoder in this context. -
Page 10: Multicast Rtp - An Overview
However, because RTP is a connectionless protocol, data delivery is not guaranteed. When data packets are lost (for example, due to excessive network traffic), the VN-Matrix 200 / 225 / 300 / 325 devices carefully manage the data stream to minimize any image disruption. -
