Tested on ARM Cortex-A55 @ 1.2 GHz with a reference USB tuner dvb t2 sdk v2.4.0
SDK v2.4.0 maintains strict compliance with the ETSI EN 302 755 standard. It fully supports the "Lite" profile required for basic receivers while offering optional support for the full T2-profile features, including: | Metric | v2
The improved PLP scheduler allows a single tuner to record 4 different programs from 4 PLPs while streaming a 5th live – perfect for home media servers. SDK v2
The SDK now includes a low-latency parser for L1-post signaling information, enabling faster channel scanning and service discovery. Developers report a 15–20% improvement in tuning times for complex T2 frames compared to v2.3.x.
