Multiport transport system for video
over Ethernet
A high-performance multiport transport system that reliably delivers digital broadcast video in real time over low-cost Ethernet networks.
The EtherCast PL4453 from Pleora Technologies is a high-performance multiport transport system that reliably delivers digital broadcast video in real time over low-cost Ethernet networks The EtherCast PL4453 is suitable for transporting SDTV (standard-definition television) and HDTV (high-definition television) content over managed Layer 2 VLANs (virtual local-area networks)

Convertors speed analogue video over IP
The iPort PT1000 ANL-2/12 and ANL-2/6 analogue video IP engines are billed as the industry's first analogue-to-IP convertors for applications requiring machine vision-grade performance.
Communications software speeds video transmission
A novel high-speed PC communications software package aims to slash the cost, enhance the performance and increase the flexibility of vision systems with large processing overheads.
VLANs cost considerably less to lease or own than the facilities traditionally used to transport broadcast-quality video, such as satellite links, ATM (Asynchronous Transport Mode) networks, or SONET/SDH networks.
"Steady improvements in the service quality of Ethernet VLANs, coupled with their low cost, make them an attractive new option for transporting broadcast video", says George Chamberlain, President of Pleora Technologies.
"Our EtherCast PL4453 is a real-time video transport system for VLANs based on field-proven technology".

Software speeds gigabit Ethernet communications
Pleora Technologies has released ground-breaking new software for real-time data streaming between GigE-connected PCs.
"We offer the system at an attractive price point, making the migration to video-over-Ethernet an easy choice for carriers, cable companies, studios, and others".
Pleora's EtherCast PL4453 is a highly flexible four-port system delivered in a standard 1U rack-mount enclosure.
Each port functions as an independently addressable IP node, can be configured as either a receiver or transmitter, and works with three different video formats: DVB-ASI (Digital Video Broadcast - Asynchronous Serial Interface), SD-SDI (Standard Definition - Serial Data Interface), and SDTi (Serial Digital Transport Interface).
The EtherCast PL4453 video IP system is derived from the field-proven IP (Internet Protocol) engine technology offered in Pleora's other EtherCast transport products and its line of iPORT products for vision applications.
Each port in the PL4453 auto-senses the format of the incoming ASI or SD/SDTi video signal, converts the video quickly and efficiently to IP, and pumps it in real time over managed Ethernet LAN/WAN facilities.
Ancillary data in the video stream, such as digital audio and timing information, is also converted.
Multicast transmission (IGMP or the Internet Group Management Protocol) is fully supported, enabling the same video stream to be distributed simultaneously to multiple destinations.
Pleora's EtherCast PL4453 system does not compress or decompress the signal, and there are no video quality compromises.
Jitter control is exceptional, transfer is lossless, and end-to end latency is low and predictable.
Any packets dropped by the network are automatically recovered.
The EtherCast PL4453 Video IP System ships with the EtherCast Configuration Utility (ECU) which detects, configures and manages multiple EtherCast engines and systems deployed in the same WAN/LAN from one PC.
The ECU also offers advanced network and status monitoring capabilities, including number of sent and received packets, packet re-send requests, lost packets, bandwidth use (up and down stream), etc.
