TAILIEUCHUNG - Digital video broadcasting (DVB)

The standard consists of four parts each covering a different structure of the transmitter network: covers sheer terrestrial transmission with single and multi-aerial structures that require only a single aerial and tuner on the receiver side; covers sheer terrestrial transmission with multi-aerial structures on both ends. Terminals suitable for this profile need to employ two tuners as well. | Digital Video Broadcasting Digital Video Broadcasting DVB Next Generation broadcasting system to Handheld physical layer specification DVB-NGH DVB Document A160 November 2012 Digital Video Broadcasting 3 Contents Intellectual Property 1 2 Normative Informative references . 12 3 Definitions symbols and Abbreviations. 22 Part I Base 4 System overview and Input Mapping of input streams onto Encapsulation into baseband Bit-interleaved coding and modulation MISO FEC encoding and interleaving inside a FEC Modulation and component Formation of interleaving frames for each Time interleaving inter-frame convolutional interleaving plus intra-frame block interleaving .29 Frame building frequency Formation of logical Mapping of logical frames onto NGH Logical channel Single tuner reception for frequency OFDM 5 Input Mode Input Transport Stream packet header Input Input Stream Synchronization optional .39 Compensating delay .39 Null Packet Deletion optional for TS only ISSY -LF ISSY-BBF and ISSY-UP modes .39 Baseband frame header BBFHDR Mode adaptation sub -system output stream ISSY-LF mode TS GSE and ISSY-UP mode TS and Stream Padding. 44 Use of the padding field for in-band In-band type A. 45 In-band type Baseband frame 6 Bit-interleaved coding and FEC Outer encoding B CH .51 Inner encoding LDPC
