Ericsson E5770 / E5775 Standard Definition Multi-Pass Encoders

E5770/E5775 Overview

The E5770/75 bring multi-pass MPEG-2 encoding to the E5700 series encoder range for the best possible performance with Reflex™ statistical multiplexing. They are especially well suited for multichannel TV systems where the ultimate in compression efficiency is required to maximize the number of TV services carried in the available bandwidth.

With extensions to the standard Reflex™ statistical multiplexing technology, the iSIS 8000™ solution enables E5770/75 encoders located over a Wide Area Network to be grouped as part of a Reflex Statistical Multiplex. The E5770/75 encoders, enabled with IP output options, can be statistically multiplexed with local encoders and can form part of the same Reflex group. Where remote encoders are statistically multiplexed over the IP network, the contributing feeds do not require a decode-recode process. The original picture quality is retained.

The E5770/75 offers breadth and depth in operational capabilities including Variable Bitrate (VBR) and Constant Bitrate (CBR) modes, Reflex™ statistical multiplexing and audio capabilities allowing operators to design their ideal encoding system and maximize their bandwidth capacity.

The E5770/75 can be remotely controlled via a web browser and can also be efficiently managed and maintained through integration into Ericsson's nCompass control system. This scalable system enables reliable, remote management and monitoring, reducing the need for costly, on-site operation.

Base Unit Features

E5770 Encoder (M2/ENC/E5770)

E5775 Encoder (M2/ENC/E5775)

The 1RU E5770 encoder features one physical expansion slot for hardware options and has a range of software enabled options for flexibility to suit specific applications. The E5775 is a 2RU version of the multi-pass encoder and features four physical expansion slots.
