摘要： A tuning system for tuning non-standard frequency RF signals which utilizes searches for non-standard RF signals by examining both a synchronization component and an AFT signal at each of a successive number of search frequencies. If the AFT signal indicates the detection of a carrier, the frequency at which this occurs is stored. However, this frequency is not caused to be tuned unless the search has been completed and the synchronization signal has not indicated the presence of a carrier. Thus, the reliability afforded by the synchronization component is maintained while adding the capability for tuning scrambled channels.

摘要： A remote control system for a television receiver includes a remote control transmitter with keys for initiating a scan type channel selection operation and a memory for storing a list of preferred channels and non-preferred channels. During a scanning operation the non-preferred channels are passed over (i.e., "skipped"). The battery of the remote control transmitter advantageously also maintains the contents of the "skip" memory so that it may be volatile. So that the same type of channel selection is available locally at the television receiver itself scan keys and an associated skip memory are also incorporated with the chassis of the television receiver. Apparatus is provided to automatically program the local skip memory with the contents of the remote skip memory so that a user does not have to program both skip memories.
摘要翻译：用于电视接收机的遥控系统包括具有用于启动扫描类型频道选择操作的键的遥控发射器和用于存储优选频道和非优选频道列表的存储器。在扫描操作期间，非优先通道被通过（即“跳过”）。遥控发射器的电池有利地还保持“跳过”存储器的内容，使得其可以是易失性的。因此，在电视接收机本身可以使用相同类型的频道选择，扫描键和相关联的跳过存储器也与电视接收机的机箱结合。提供装置以利用远程跳过存储器的内容来自动编程本地跳过存储器，使得用户不必对两个跳过存储器进行编程。
