[0059] 步骤203,节目制作分区根据设置关于每个分类的匹配条件对节目单包含的节目进行分类,对应每个分类分别生成节目列表。 [0059] Step 203, the program making the program classifies the partition comprises a single program according to the setting of the matching condition with respect to each classification, generates a program list corresponding to each category, respectively.

[0060] 具体地,本步骤包括: [0060] Specifically, this step includes:

[0061] 步骤2031,建立分类。 [0061] Step 2031, the establishment of classification.

[0062] 例如,建立的分类包括:新闻30分,焦点访谈,今日说法等。 [0062] For example, the classification established include: News 30, Focus, today parlance.

[0063] 步骤2032,对应每个分类分别设置匹配条件。 [0063] Step 2032, respectively provided corresponding to each category matching condition.

[0064] 参见图5,图5示出了匹配条件、分类、节目列表三者之间关系的一个实例。 [0064] Referring to FIG. 5, FIG. 5 shows a match condition, classification, an example of the relationship between the three program listings.

[0065] 例如,对应“新闻30分”设置的匹配条件包括匹配条件1和匹配条件2 :匹配条件1为,播放起始时间为07:00 ;匹配条件2为,节目名称为“新闻30分”。 [0065] For example, corresponding to "News 30" includes a matching set matching condition and the matching condition 1 condition 2: 1 as the matching condition, the play start time is 07:00; 2 matching condition, the program name is "News 30 . " 对应“焦点访谈”设置的匹配条件包括匹配条件3和匹配条件4 :匹配条件3为,节目名称为“焦点访谈”;匹配条件4为,播放截止时间为18:30。 Matching condition corresponding to the "Focus" includes a matching conditions set match condition 3 and 4: 3 for the matching condition, the program entitled "Focus"; 4 match condition, playback deadline 18:30. 对应“今日说法”设置的匹配条件包括匹配条件5、匹配条件6和匹配条件7 :匹配条件5为,播放起始时间为12:41 ;匹配条件6为,播放截止时间为12 : 58 ;匹配条件6为,节目名称为“今日说法”。 Corresponding to "today that" matching comprises matching condition setting conditions 5, 6 and the match condition matching condition 7: 5 is a matching condition, the play start time is 12:41; 6 matching condition, playback deadline 12:58; Match 6 conditions, the program name is "today's statement."
