[0058] 步骤S21,逐一将所获取频道的IS0_639_language_code中的语言与所述预置语言进行对比; [0058] step S21, the channel one by one in the acquired IS0_639_language_code language and comparing the preset language;

[0059]步骤S22,若对比结果相同,则判断所获取频道的当前语言与所述预置语言匹配; [0059] Step S22, the same result if the comparison, it is determined that the acquired channel current language matches the preset language;

[0060]步骤S23,若对比结果不相同,则判断所获取频道的当前语言与所述预置语言不匹配。 [0060] Step S23, the comparison results if not identical, determines whether the acquired channel current language does not match the preset language.

[0061 ]逐一捕获所获取频道的IS0_639_language_code,将IS0_639_language_ code中的值与根据ISO 639-2 Code的编码规则存储在内部的值进行比对。 [0061] IS0_639_language_code captured by one of the acquired channel, the value of IS0_639_language_ code and to compare the value of the internal memory according to the encoding rules of ISO 639-2 Code. 具体地,如将当前频道IS0_639_language_code中的值与内部存储的“eng”进行比对,如果相同,则该频道的当前语言与预置语言匹配,并跳转到下一个频道重复比对步骤;如果不同,则该频道的当前语言与预置语言不匹配,跳转步骤S14,将该频道排序在当前语言与预置语言匹配的频道之后。 Specifically, as the current value of the channel IS0_639_language_code internally stored "eng" for comparison, if the same, then the current language matches the language preset channel, and go to the next channel than repeating step; if are different, the channel does not match the current language and the language preset jump step S14, the sorting channels after the current language matches the language preset channels. 再如将当前频道IS0_639_language_code中的值先后与内部存储的“chi”和“zho”进行比对,只要其与内部存储的“chi”或“zho”相同,就判断该频道的当前语言与预置语言匹配,并跳转到下一个频道重复比对步骤;如果都不相同,就判断该频道的当前语言与预置语言不匹配,跳转步骤S14,将该频道排序在当前语言与预置语言匹配的频道之后。 Another example is the value of the current channel is successively IS0_639_language_code for comparison with internally stored "chi" and "zho", as long as the "chi" or "zho" the same as the internal storage, and determines that the current language for the channel preset language match, go to the next channel and repeating the step of comparing; if not the same, it is determined that the channel does not match the current language and the language preset jump step S14, the sorting channels in the current language and the language preset after the match channel.

[0062]在具体实施例中,数字电视将与预置语言不匹配的频道排序在与预置语言匹配的频道之后的具体步骤包括: [0062] In a particular embodiment, the digital television will not match with the preset language specific sorting step after the channel preset language matches the channel comprises:

[0063]将与预置语言匹配的频道存储到语言匹配频道列表中,将与预置语言不匹配的频道存储到语言不匹配频道列表中;其中语言匹配频道列表中最大频道号小于语言不匹配频道列表中最小频道号。 [0063] matched with the preset language channel to a channel list matches the language, the language does not match with the preset language does not match the channel to a channel list; where language matches the channel list is less than the maximum channel number does not match the language the channel list the smallest channel number.

[0064]对数字电视物理频道进行频道区域划分,包括语言匹配频道列表和语言不匹配频道列表,将步骤S12中判断的与预置语言匹配的频道存储到语言匹配频道列表中,将步骤S12中判断的与预置语言不匹配的频道储到语言不匹配频道列表中。 [0064] physical channel for digital television channel area division, comprising matching channel list does not match the language and the language channel list stored in step S12 is determined to match with the preset language into language channel matching the channel list in Step S12 Analyzing the language does not match the pre-storage channel to the channel list does not match the language. 并将语言不匹配频道列表排序在语言匹配频道列表之后,使得语言匹配频道列表中最大频道号小于语言不匹配频道列表中最小频道号。 And the channel does not match the language after the language match list is sorted channel list, such that the language matching channel list is less than the maximum channel number does not match the language of the smallest channel number in the channel list.
