Abstract

本发明公开了一种优化的机顶盒广告系统数据自适应接收方法,属于数字电视机顶盒技术领域,包括以下步骤：机顶盒开机启动广告系统后，广告系统实时获取广告数据；用户切台到有广告数据的频点时，将广告数据回传给广告系统模块；广告系统模块收到数据后，获取当前调谐器锁定的频点参数，如频率，符号率等，将获得的频点参数保存为新广告频点；机顶盒下次开机时从新广告频点自动下载广告，无论前端频点如何调整、变化，也无论分前端如何变频，只要前端和子前端某个频点里有广告数据，通过本方法就可以自适应各种情况。同时还降低了广电运营维护成本，降低了各供货商软件开发维护成本。

Description

一种优化的机顶盒广告系统数据自适应接收方法
技术领域
本发明属于数字电视机顶盒技术领域，具体涉及一种优化的机顶盒广告系统数据自适应接收方法。
背景技术
当前，常规的机顶盒广告系统的数据接收都是固定在一个频点，广电前端选定广告频点，告知各供货商，供货商将这个频点固定到机顶盒软件里，在开机或者切换到这个频点对应的节目时才能更新广告。这种实现方案存在以下不足：
(1)前端广告频点受信号干扰严重，必须更换频点时；
(2)前端因业务需要，需要更改广告频点时；
(3)分前端有变频情况时，如总前端广告播发在490频点，分前端将490频点重新调制成506时。
以上这些情况，因为软件没有做自适应不具通用性，必须修改软件大网升级后才能实现广告的更新。但即使如此，针对问题(3)，一个大前端有多个子前端的情况仍然无法满足。综上，设计一种自适应数据接收的广告系统相当必要。
发明内容
本发明的目的在于设计一种优化的机顶盒广告系统数据自适应接收方法，弥补了当广告播发频点发生改变时必须通过修改机顶盒软件大网升级才能实现广告更新的不足，尤其适用于分前端广告频率有变频的情况。
本发明采取以下技术方案：一种优化的机顶盒广告系统数据自适应接收方法，包括以下步骤：
(1)机顶盒开机启动广告系统后，广告系统实时获取广告数据；
(2)用户切台到有广告数据的频点时，将广告数据回传给广告系统模块；
(3)广告系统模块收到数据后，获取当前调谐器锁定的频点参数，如频率，符号率等，将获得的频点参数保存为新广告频点。这样设置的理由是：哪个频点过到了广告数据就表示哪个频点在播发广告流，也就是前端的广告频点；
(4)机顶盒下次开机时从新广告频点自动下载广告。
本发明与现有技术相比，具有以下的有益效果：
本发明提出了一种优化的机顶盒广告数据自适应接收方法。当前端广告数据播发的频点发生改变时，后端机顶盒自动保存新频点参数到FLASH，并重新从新频点下载广告数据，达到自适应更新的效果。弥补之前实现方案在广告播发频点发生改变时必须通过修改机顶盒软件大网升级才能实现更新的不足，轻松应对分前端有变频的情况；同时还降低了广电运营维护成本，降低了各供货商软件开发维护成本。
附图说明
图1为本发明的系统流程图；
图2为本发明中分前端变频拓扑图。
具体实施方式
下面结合本发明的实施例对本发明作进一步的阐述和说明。
具体实施例：
如图1所示，一种优化的机顶盒广告系统数据自适应接收方法，其特征在于包括以下步骤：
(1)机顶盒开机启动广告系统后，广告系统实时获取广告数据；
(2)用户切台到有广告数据的频点时，将广告数据回传给广告系统模块；
(3)广告系统模块收到数据后，获取当前调谐器锁定的频点参数，如频率，符号率等，将获得的频点参数保存为新广告频点。这样设置的理由是：哪个频点过到了广告数据就表示哪个频点在播发广告流，也就是前端的广告频点；
(4)机顶盒下次开机时从新频点自动下载广告。
如图2所示，当总前端广告播发在490频点，分前端将490频点重新调制成506新频点，则STB(机顶盒)自动在506新频点下载广告。
综上，无论前端频点如何调整、变化，也无论分前端如何变频，只要前端和子前端某个频点里有广告数据，通过本方法就可以自适应各种情况。保证能正常下载到广告数据，并自动保存新频点为广告频点
以下附表1中为本发明的主要实现代码：
尽管这里参照本发明的解释性实施例对本发明进行了描述，上述实施例仅为本发明较佳的实施方式，本发明的实施方式并不受上述实施例的限制，应该理解，本领域技术人员可以设计出很多其他的修改和实施方式，这些修改和实施方式将落在本申请公开的原则范围和精神之内。
