The World Leader in High Performance Signal Processing Solutions DRM Receivers using Programmable DSP Chips

Agenda u About u DRM Receivers: ADI paving the way u Summary

Digital Radio Mondiale (DRM) Offers…. u DRM delivers near FM sound quality with frequencies below 30 MHz u DRM+ delivers near CD sound quality with frequencies below 120 MHz u DRM is Robust against fading and interference l u Supports datacasting l u u u Provides a wide geographic coverage and thus the most suitable free-to-air mode of broadcasting RDS type metadata or program associated data Service Label: Easy Tuning by station name instead of frequency Time & Date: Reference for tuning processes Best Frequency Tuning (AFS): Scheduled frequency selection Service Following: Alternative frequency selection Announcement l Dynamic Service interruption for Flash Reports (Travel, News, Weather, . . . )

The World Leader in High Performance Signal Processing Solutions DRM Receivers ADI Paving the way

The Blackfin Advantage Combines Full DSP and MCU Capabilities

ADI’s Response to Market Opportunity u. ADI’s Realization: l AM/FM: Older technology with inherent limitations l New digital radio standards are now available to the broadcasters u. Decided to use Blackfin & create a digital radio based on DRM standards: l Excellent fit for digital signal processing and micro-controller function l Choice of a large number of manufacturers l Low-cost Blackfin Silicon with integrated peripherals u Enables creation of a multi-featured product u. Multiple generations of products and heavy reuse of software IP available with us and our customers

The Echo System Created u ADI’s Strength l Design and manufacturing of signal processing components u Created an echo system to collate other strengths required for making a good DRM receiver u Established l BBC partnerships with industry leaders: for DRM C-code l Coding Technologies for audio decoders (AAC, CELP & HVXC) l Deutsch l Jasmin Welle for active antenna & front end Infotech for porting software on Blackfin processor

DRM Radio: Key Specifications Minimum Requirements (2) u Channel Decoder Robustness modes: A, B, C & D l Signal Constellations: u 4 and 16 QAM for SDC (Service Description Channel) u 16 and 64 QAM for MSC (Main Service Channel) u Protection levels: 0, 1, 2 & 3 l Hierarchical modulation l Short & long interleaver depths l Equal and unequal error protection l u Source Decoders Three coding systems: u AAC+ with Error Concealment u CELP u HVXC l High Frequency reconstruction method SBR l All audio modes: Stereo, Mono & Parametric Stereo l
