WISDOM77 RTP SLOT: What are AMBER Alerts?

WISDOM77 RTP SLOT ATSC-M/H bandwidth consumes fixed chunks of 917 kbit/s out of the total ATSC Bandwidth. The 8VSB modulation used by ATSC allows SFN transmissions. Major elements include Internet Protocol (IPv4), UniDirectional Protocol (UDP), Signaling Channel Service, FLUTE over Asynchronous Layered Coding (ALC) / Layered Coding Transport (LCT), Network Time Protocol (NTP) time service, and Real-time Transport Protocol (RTP) / RTP Control Protocol (RTCP). A 1/4 rate PCCC (Parallel Concatenated Convolutional Code) is also employed as an inner code for the M/H signaling channel, which includes FIC (Fast Information Channel) and TPC (Transmission Parameter Channel). One M/H Frame is equivalent in size to 20 VSB Frames and has an offset of 37 transport stream (TS) packets relative to the beginning of the VSB Frame. In case of signaling with ESG, the complete SDP-File is transmitted. The correction is improved by an additional CRC checksum since bytes can be marked as defective before they are decoded (erasure decoding).|Characteristics Of Slot Demo Pragmatic
