本公告CEA-CEB12-B为高级电视系统委员会（ATSC）节目和系统信息协议（PSIP）兼容接收机、有线数字电视接收机、个人录音机和其他消费电子设备的开发和实施提供了指导。它包括对设备功能的建议和建议。CEA-CEB12-B不应以任何方式禁止消费类设备制造商包括附加功能，CEA-CEB12-B不应被解释为建议设备性能的上限。可以考虑许多可能的PSIP实施场景。然而，CEA-CEB12-B并没有对可能性进行详尽的分类，而是讨论了一些更简单的情况。CEA-CEB12-B假设用户在没有专业协助的情况下设置接收器，并且设置是菜单驱动的、简单的，并且大部分是自动的。然而，接收器可能由经过培训的技术人员进行专业安装和设置。 CEA-CEB12-B目前既不针对具有内置卫星接收能力的接收机，也不针对使用电话线访问EPG数据库的接收机。它也不涉及有线机顶盒、卫星电视盒、录像机、DVD播放机或其他辅助设备或连接。CEA-CEB12-B使用ATSC A/65中定义的术语，应与ATSC A/65一起阅读。注——设计者应注意，FCC法规可能适用于本CEA-CEB12-B中所述的功能。尽管已尽一切合理努力使本CEA-CEB12-B符合截至发布之日的现行法规，但实施者应注意阅读并理解所有适用法规。

This bulletin, CEA-CEB12-B, provides guidance for the development and implementation of Advanced Television Systems Committee (ATSC) Program and System Information Protocol (PSIP)-compliant receivers, cable-ready DTV receivers, personal recorders and other consumer electronics devices. It includes recommendations and suggestions for device functionality. CEA-CEB12-B should in no way prohibit consumer device manufacturers from including additional features, and CEA-CEB12-B should not be interpreted as recommending an upper limit to device performance. Numerous possible PSIP implementation scenarios could be considered. However, CEA-CEB12-B does not include an exhaustive classification of the possibilities, rather, some simpler scenarios are addressed. CEA-CEB12-B assumes that the user sets up the receiver without professional assistance and that setup is menu-driven, simple and mostly automatic. It is possible, however, that receivers may be professionally installed and set up by trained technicians. CEA-CEB12-B does not currently address receivers that have built-in satellite receiving capability, nor receivers that access EPG databases using phone lines. Nor does it address cable set top boxes, satellite boxes, VCRs, DVD players or other auxiliary devices or connections. CEA-CEB12-B uses the terminology defined in ATSC A/65 and should be read in conjunction with ATSC A/65. NOTE -- Designers should be aware that there are FCC regulations that may apply to functions described in this CEA-CEB12-B. While every reasonable attempt was made to have this CEA-CEB12-B conform to those regulations in place as of the date of publication, implementers are cautioned to read and understand all applicable regulations.
