Patent number: 7580082Abstract: A digital broadcasting receiver judges whether or not a received program is a data broadcasting program. When the received program is the data broadcasting program, processing for judging a remote control signal from a remote control transmitter is performed as usual. When it is judged that the remote control signal is a remote control signal related to a key associated with channel selection, however, processing corresponding to the signal is not performed. That is, processing for judging whether or not the received program is the data broadcasting program to automatically nullify (lock) a channel change.Type: GrantFiled: October 10, 2003Date of Patent: August 25, 2009Assignee: Sanyo Electric Co., Ltd.Inventor: Kiyoshi Matsumoto

Publication number: 20080250463Abstract: A digital broadcasting receiver is equipped with: either at least one lookup table of positive and negative weighted BER factors each assigned to one of predetermined classes of BER of a receivable broadcast signal or a function for deriving said weighted BER factors; at least one counter adapted to classify measured values of BER of the broadcast signal received, obtain BER factors assigned to the measured values, and add up said weighted BER factors as BER is measured at regular time intervals; and control means for controlling said switching means based on the count of said counter, thereby generating proper switching timing for switching broadcast layers in response to the varying reception status of the broadcast signal. As a result, in switching the layers to be presented, frequent switching of the layers can be suppressed while preventing disturbances in video and audio caused by reception errors. The receiver can easily manage holding time for holding the current layer as it is prior to a switching.Type: ApplicationFiled: April 8, 2008Publication date: October 9, 2008Applicant: SANYO ELECTRIC CO., LTD.Inventors: Toru SHIBUSAWA, Kiyoshi MATSUMOTO
