Layered Division Multiplexing (LDM) LDM is a new transmission scheme that uses spectrum overlay technology to super-impose multiple physical layer data streams with different power levels, error correction codes and modulations for different services and reception environments; For each LDM layer, 100% of the RF bandwidth and 100% of the time are used to transmit the multi-layered signals for spectrum efficiency and flexible use of the spectrum; Signal cancellation can be used to retrieve the robust upper layer signal first, cancel it from the received signal, and then start the decoding of lower layer signal; 5 db 5 db RF Channel BW LDM overlay spectrum Upper Layer Lower Layer Future Extension Layer The upper layer (UL) is ultra-robust and well suited for HD portable, indoor, mobile reception. The high data rate lower layer (LL) transmission system is well suited for multiple-hd and 4k-UHD high data rate fixed reception. Future Extension Layer (FEL) can be added later with full backward compatibility.

SFN BENEFITS ATSC 3.0 SINGLE FREQUENCY NETWORKS
SFN FOR ATSC 3.0 ATSC 3.0 will support a SFN (Single Frequency Network) infrastructure Sparse and Dense Networks are possible SFN is a broadcast network planning strategy that allows efficient utilization of spectrum by expanding coverage/service without additional frequency allotment
IMPACT OF SFN ON SERVICE Total received signal strength may increase coverage in overlapping region providing SFN Gain Indoor reception with simple receivers and antennas Better service inside of coverage contours including deep building penetration Geographic (SFN zoned) services Interference mitigation Rx Path Diversity is biggest component of gain
SFN GAIN AND SPATIAL DIVERSITY PROVIDE IMPROVED QOS SFN provides increased service area for services Pedestrian, Mobile, Indoor Increased gains possible with MISO/receiver diversity Path Diversity provides real system gain
MAXIMUM TX DIVERSITY SFN Sparse SFN using 3-5 Transmitters Provides Path Diversity for Rx Increased Field Strength throughout coverage area Supports Targeted Ad Business Models Shared (Co-Located) Stations makes concept financially viable ATSC 3.0 includes Filter Code Set for best performance in Rx
HOW TO TRANSITION TO ATSC 3.0? IP upgrade to Next Gen TV (3.0) Fundamentally different than the earlier DTV transition: Digital to digital upgrade No request for a second channel No request for government funded set-top-box converter Propose initial voluntary update: no government mandate and marketplace will decide Optional for the consumer to upgrade to Next Gen TV New sets will support both 1.0 and 3.0 for a limited time Will coexist with the current 1.0 standard (utilizing channel sharing) so no disruption to consumer viewing on current 1.0 sets Last transition
MARKET TRANSITION TO ATSC 3.0 FCC Rules for Broadcasters November 16 th Voluntary Operation of ATSC 3.0 Adoption of ATSC 3.0 will be Market Driven No Governmental Tuner Mandates TV set manufacturers have pledged to make sets ATSC 1/3 compatible Transition requires unprecedented cooperation among broadcasters in each TV Market Key to transition is Channel Sharing Industry Consolidation & Joint Ventures are key drivers
STATION TRANSITION CONCEPT FCC will not provide additional spectrum to manage transition (unlike analog to digital transition) Congress will not provide subsidy for converter boxes (unlike analog to digital transition) Industry will ask FCC to allow broadcasters to begin ATSC 3.0 on their own timetable initially, all voluntary and market driven Will Coincide with Auction Re-Pack Stations will partner with each other to share spectrum Commercial launch and growth of ATSC 3.0 services while maintaining a limited service to ATSC 1.0 legacy viewers
