Publication number: 20220271775Abstract: The present technology relates to a data processing device and a data processing method which can ensure high communication quality in data transmission using LDPC codes. In group-wise interleaving, an LDPC code having a code length N of 64800 bits and a coding rate r of 13/15 is interleaved in a unit of a bit group of 360 bits. In group-wise deinterleaving, a sequence of bit groups of the LDPC code which has been subjected to the group-wise interleaving is returned to an original sequence. The present technology can be applied to, for example, a case in which data transmission is performed using LDPC codes.Type: ApplicationFiled: May 5, 2022Publication date: August 25, 2022Inventors: Ryoji IKEGAYA, Makiko YAMAMOTO, Yuji SHINOHARA

Publication number: 20220248106Abstract: A transmitter for transmitting payload data and emergency information using data symbols in a single-carrier or multi-carrier broadcast system comprises a modulator configured to modulate one or more transmission symbols with signaling data for use in detecting and recovering the payload data at a receiver and to modulate one or more transmission symbols with the payload data. An emergency information receiver receives emergency information carrying information of an actual emergency. An emergency information embedder embeds emergency information into one or more transmission symbols, wherein the emergency information is embedded within a predetermined time period after its reception by using a resource used for carrying signaling data and/or payload data if no emergency information shall be transmitted. A transmission unit transmits the transmission symbols.Type: ApplicationFiled: November 15, 2021Publication date: August 4, 2022Applicant: Saturn Licensing LLCInventors: Lothar STADELMEIER, Makiko KAN, Nabil LOGHIN, Daniel SCHNEIDER, Jan ZOELLNER, Lachlan Bruce MICHAEL, Yuji SHINOHARA, Samuel Asangbeng ATUNGSIRI, Gholam Hosein ASJADI, Matthew Paul Athol TAYLOR
