Abstract

本发明涉及电视接收机等的选台电路,在用0— 9数字键直接选台时自动地对两位选台与三位选台 加以切换。该选台电路由下列部分组成:自动编程动 作单元1、根据自动编程动作单元1判断有无100频 道以上接收台的百位判断单元2、0—9数字键输入 3,以及根据百位判断单元2与0—9数字键输入3 的信息进行选台动作的选台判断单元4。选台时能 自动切换,使用者的操作性可获得提高。

Description

本发明涉及电视接收机等所用的选台电路。
近年来,对声像设备功能的方便性的要求很高,有的设备可接收100多条频道。
以下参照附图说明一例判断是否有100频道以上接收台的自动百位判别电路。
图2示出的是现有选台电路的方框构成图。
这里说明借助于0-9数字键输入的直接选台。从0-9数字键输入两次时,经过一定时间以后便进行频道1-99的选台(以下称为两位选台)。而且,0-9数字键第一次键入1,接着在一定时间内第二次、第三次键入数字时,便成为100以上频道的选台(以下称为三位选台)。
图2中,5是0-9数字键,6是根据0-9数字键5进行选台动作的选台判断单元。
以下就上述构成的选台电路说明其动作。
首先0-9数字键5键入数字时,选台判断单元6在0-9数字键输入5的键入信息为1时判断为百位输入,而除1以外时则判断为十位输入。选台判断单元基于此判断,再根据第二次、第三次0-9数字键输入5的输入信息进行选台动作。
不过上述构成存在以下问题,即只要第一次输入信息为1就需要进行三次输入操作,从而使只用频道10-19而不用100频道以上的使用者感到不便。
本发明鉴于上述问题,其目的在于提供一种自动百位判别电路,当0-9数字键输入为1时,可以判别有无100频道以上接收台,并在将输入的1作为百位输入或作为十位输入之间自动切换。
为了解决上述问题,本发明自动百位判别电路包括下列构成:进行ADDch(编址频道)登记的自动编程动作单元;由上述自动编程动作单元的信息判断有无100频道以上的接收台的百位判断单元;取得0-9数字键的键入与上述百位判断单元的信息进行选台的选台判断单元。
本发明按照上述构成,由百位判断单元依据自动编程动作单元判断有无100频道以上的接收台,由选台判断单元对该判断结果以及0-9数字键的键入作判断,以进行两位或三位的选台动作。
图1是本发明一实施例选台电路的方框构成图。
图2是现有的选台电路的方框构成图。
以下参照附图说明本发明实施例。
图1示出本发明一实施例自动百位判别电路的方框构成图。1是自动编程动作单元,2是根据自动编程动作单元1判断有无100多条频道的百位判断单元,3是0-9数字键输入,4是根据百位判断单元2的结果与0-9数字键输入3的信息进行选台动作的选台判断单元。
以下就如上构成的自动百位判别电路说明其动作。
首先,当自动编程动作单元1动作时,仅将陆续广播的频道作为编址频道予以登记。百位判断单元2则根据自动编程动作单元1的动作结果判断有无100频道以上的接收台。
接下来,当0-9数字键3键入数字时,选台判断单元4根据输入信息为1时百位判断单元2的判断结果,对两位选台与三位选台进行切换。
百位判断单元2的结果判断为有100频道以上的接收台时,选台判断单元4将0-9数字键3的输入作为百位输入,下一0-9数字键3的输入作为十位输入,再下一0-9数字键3的输入作为个位输入,这样来进行三位选台动作。
如上所述的操作可进行100频道以上接收台的选台。
而且,在对频道10-19进行选台的情况下,十位输入后一定期间内不再有0-9数字键3的输入时,选台判断单元4就将百位输入作为十位输入,十位输入作为个位输入,来进行两位选台动作。
百位判断单元2的结果判断为没有100频道以上的接收台时,选台判断单元4就将0-9数字键3的输入作为十位输入,若再有0-9数字键输入3输入,则作为个位输入,这样进行两位选台动作。
另外,本实施例中不仅仅限于判断有无100频道以上的接收台,例如还判断有无200频道以上的接收台,对于1以及2的0-9数字键输入,都进行百位、十位的输入切换。
而且,本实施例中,有100频道以上的接收台时,0-9数字键输入1为百位输入的判别方法不仅限于上文所述,例如还可以1的输入持续一定时间时作为百位输入,1的输入不足一定时间时即作为十位输入。
综上所述,按照本实施例,通过在现有的选台电路构成当中新增设自动编程动作单元与百位判断单元,就可以实现前所未有的,自动判断有无100频道以上接收台的功能。
总之,根据本发明,设置进行ADDch登记的自动编程动作单元,根据上述自动编程动作单元的信息判断有无100频道以上接收台的百位判断单元,进行直接选台用的0-9数字键输入,以及取得上述数字键输入的信息与上述百位判断单元的结果进行选台的选台判断单元,在借助0-9数字键直接选台时就可以自动判别有无100频道以上的接收台,其实用效果很好。
