New features¶
Clientless user interface¶
This capability facilitates Observer monitoring on Chrome, Firefox and Safari (MAC) Internet browsers without requiring a prior installation of a local player and its active-x component. In addition it facilitates large Observer system deployments.
The clientless interface has a slightly reduced feature set from the active-x based Observer player. Keyboard shortcuts (see Appendix for details) complement the simplified player control-bar functionality (highlighted below).
Prior to using the clientless interface (based on the HLS protocol) on the Observer system, older encoder media need to be converted to H264 video and AAC audio formats.
Multi-view mode¶
The Multi-view mode supports multiple simultaneous players while using system resources efficiently.
It can be used to watch multiple programs on a wall of monitors for example while in parallel using the desktop interface to target and troubleshoot a suspect stream.
The Multi-view mode is enabled automatically on the Observer system after a user opens more than six players simultaneously. It supports up to twelve players at the same time. These defaults can be readjusted by Volicon Support if required.
Multi-view limitations¶
This mode has the following limitation:
Player control-bar is not displayed
However the keyboard shortcuts can be used instead to control these player functions as well, see the appendix for details.
Multicast¶
IP multicast is a technique for one-to-many communication over an IP network infrastructure. It scales to a large receiver population through an efficient use of the network and is convenient to use by not requiring prior knowledge of the receiver addresses. The source only needs to send a single packet even if it needs to be delivered to a large number of receivers. The nodes in the network replicate the packets automatically and deliver these to multiple receivers as needed.
IP multicast facilitates the Observer system to stream TS media over customer multicast networks.
SCTE-35 DPI monitoring¶
DPI allows cable head ends and broadcast affiliates to insert locally-generated commercials and short programs into remotely distributed regional programs, before delivering these to home viewers.
DPI insertion enables the monitoring, logging, and frame-accurate display of content, metadata and in/out point markers to insure proper DPI message delivery and display.
In general the TS (SCTE-35 protocol) and SDI (SCTE-104 protocol) originated streams are used. Currently we support only the SCTE-35 protocol.
