Aperi TICO Encoder & Decoder App

Encoding and multiplexing for distribution and re-distribution

Aperi’s TICO Encoder and Decoder are FPGA-based applications designed for Aperi’s microserver platform and are available from the Aperi App Store.


The TICO Encoder and Decoder app enables a 4K UHD channel that provides virtually lossless quality. The 4K UHD signal is received as four 3G feeds and employs the TICO mezzanine compression to create a codestream that is packetized and encapsulated per SMPTE RDD35, conforming to SMPTE 2110/VSF TR-03 standards. It’s formatted as a quad-link 2SI.


Audio data is de-embedded from the first channel, and mapped into IP with either AES67 or RFC-3190. Ancillary data is encapsulated into IP with the SMPTE 2038 specification.


In the 3G quad link SDI mode, up to four bidirectional channels can simultaneously process all de-embedding, compression, and encapsulation, effectively bypassing the quad-link formatter, and processing independently. SMPTE 2022-7 RTP replication and merging is used for network protection.


Extensive flexibility and precise configuration options make Aperi’s TICO encoder and decoder ideal for a variety of scenarios. It effectively can encode and decode 4K UHD with near mathematically lossless 4K and 3G SDI quality, all at extremely low-latencies.
