电视接收机的频道获取方法和装置
摘要：
通过确定电视接收机中每个频道的载波跟踪回路频率偏置和符号定时恢复偏置来提高数字电视信号接收机中的频道获取。将偏置存储在每个频道的相应EEPROM(CTL EEPROM、STR EEPROM)中。当将在TV接收机中获取频道时，将调谐命令提供给适当的EEPROM(CTL EEPROM、STR EEPROM)，并且将相应值传送给VSB解调器(40)，以便开始信道的获取。
摘要（英）：

Channel acquisition in a digital television signal receiver is improved by determining the carrier tracking loop frequency offsets and the symbol timing recovery offsets for each channel in the television receiver. Offsets are stored in respective EEPROMs for each channel. When a channel is to be acquired in the TV receiver the tune command will be applied to the appropriate EEPROMs and the respective values are conveyed to the VSB demodulator to start acquisition of the channel.
