Overview of Recorded Streams

Encoders convert video signals to highly compressed signals that can be transferred over a network.

•The VNR 100 records the compressed signals from the network, without further processing.

•As a minimum, each recording contains a video element.

•A recording may also include elements containing audio, data, and whiteboard information (if these are present and enabled at the encoder). If these are selected for storage, each element is stored as an individual file within the same directory.

Overview of Stream Playback

•The VNR 100 plays back saved data without processing. It is already in a highly compressed format that can be transferred over a network.

•When a recording that contains multiple elements is selected for playback, all the necessary files are loaded.

•The video content is always played back.

•When present, audio, data, and whiteboard elements may be enabled or disabled for playback. If they are enabled, the audio, whiteboard, and data elements are always slaved to the video stream.

Decoders take the highly compressed signals from the network and reconvert them to the uncompressed format required by a display device.

Transport Protocols Used for Streaming

Source data from a VN-Matrix encoder can be distributed to multiple displays or decoders (one-to-many) or to a single display or decoder (point-to-point). A previously recorded stream can be distributed in the same way and, as the source of an encoded stream, the recorder may be thought of as an encoder in this context.

A stream may be transported over the network from the source (encoder, recorded stream) to the display (decoder) using one of three methods:

•Multicast Real-time Transport Protocol (RTP)

•Unicast Real-time Transport Protocol (RTP)

•Unicast Transmission Control Protocol (TCP)

By default, the VNR 100 recorder provides a choice of unicast RTP or unicast TCP transport protocols. A multicast transport protocol may be configured if required (see the Enterprise Controller User Guide).

NOTES:

•During playback of a recorded stream, the transport protocol can be TCP, RTP, or

RTP Multicast. The protocol is specified on the VNM Enterprise Controller.

•When a stream is recording, the VNR 100 may be considered as a display (decoder) device.
