Latest Patents

Yamagata’s listed inventions address transport stream processing and digital broadcasting reception.

“Transport Stream Decoder and Digital Broadcasting Receiving Device Using the Same” describes a decoder that synchronizes multiple transport streams with their corresponding input clocks. It then time-division multiplexes the streams using an internal processing clock and adds identification signals to indicate which stream each signal represents. The design aims to handle different types of transport streams while keeping the decoder’s circuit scale down.

“TS Data Filtering Circuit in Digital Broadcasting Receiver” describes a filtering system that stores packet data in memory when hardware cannot determine whether the data should be acquired. Software then checks the stored data, with the matching process beginning once a predetermined number of effective bytes has been stored.
