LA-5269 - Dolby Digital/Plus Transcoder
LA-5269 provides everything necessary to accomplish simple, reliable encoding or transcoding. Features include frame synchronized AES inputs, HD/SD-SDI, or AES-11 (DARS) reference, plus internal or external serial metadata. Coding is provided by a Dolby-manufactured encoder module featuring the latest versions of the codecs for superior sound quality.
Additional functionality can be added as needed via software, enabling support of additional encoding and/or transcoding flavors.
A bright LED display and rotary encoder with four control keys provide easy menu navigation. Dual redundant power supplies, GPI/O, and a hard relay bypass are standard, while SNMP monitoring is offered as an option.
Frame synchronized AES inputs
HD/SD-SDI or AES-II (DARS) reference
Internal or external serial metadata
Available SNMP monitoring
Encode to Dolby Digital (AC-3) from PCM, encode to Dolby Digital Plus (E-AC-3) from PCM, transcode Dolby Digital to Dolby Digital Plus, encode to AAC or HE-AAC (with or without Dolby metadata) from PCM. Dolby E decoding is optional, and allows Dolby E sources to be decoded and encoded into Dolby Digital, Dolby Digital Plus, HE-AAC and AAC.
The LA-5269 provides a low-cost encoding platform that allows features to be enabled without the need to replace hardware. A simple software update can add features or codecs at any time. System status and additional I/O features can also be added as needed, essentially allowing broadcasters to pay for only what they need.
