目前，用户在使用智能电视时，在切换直播频道时，用户需要通过遥控器连续输入切换后的频道号，然后点击“OK”按键，或者等待一段时间后，智能电视才能进行频道切换。即使当用户输入的频道号的长度达到最大频道号长度时，不能识别到用户输入的频道号已达到最大长度而切换频道，还需要用户点击“OK”按键，或者等待一段时间，用户的使用体现差。并且，由于智能电视不能识别到用户输入的频道号已达到最大长度而切换频道，会出现用户继续点击遥控器的数字按键，导致最后输入的频道号的长度大于最大长度而无法切换频道的情况。综上，现有技术中智能电视的用户使用体验差。
因此，本申请实施例提出：显示设备接收用户通过遥控器等控制装置按照频道号顺序输入的至少一个频道号信息，获得频道号，例如，用户连续3次分 别输入1、2、3，则频道号为123。其中，显示设备在每次接收到用户输入的组成频道号的频道号信息，获得一个频道号时，则判断该频道号的长度是否达到频道号的最大长度。如果是，直接将显示设备的频道切换为该频道号对应的频道，或者定位到该频道号指定的频道上，而不需要用户输入“OK”，或者等待后再切换或定位，并且，也避免了用户继续输入频道号信息，提高了显示设备的智能化程度，从而提高了用户体验。
图3A-3C中示例性示出了通过操作控制装置100而使显示设备200提供的一个GUI400的示意图。
如图2所示，在显示设备的显示器上正在直播第一频道号指示的第一频道的节目内容时，用户通过按压遥控器上的可以组成频道号的按键，例如，数字键、“-”、“.”，向显示设备输入指示频道号信息的指令。其中，一个频道号需要用户至少输入一次指示频道号信息的指令，显示设备响应于每次接收到的指示频道号信息的指令后，获得第二频道号。例如，当用户按压数字键“1”时，显示设备获得的第二频道号为1，如图3A所示，在显示设备的显示器上将第二频道号1在显示器上位于第一频道的节目内容的上方显示；用户再次按压数字键“2”时，更新显示设备获得的第二频道号为12，如图3B所示，显示器上显示的第二频道号为12。
若当前频道类型的频道对应的频道号最大长度为2位，显示设备响应于每次接收到的指示频道号信息的指令后，获得第二频道号后，判断第二频道号的长度是否等于频道号最大长度，若第二频道号的长度等于频道号最大长度，则显示设备直接将第一频道节目内容切换为第二频道号指示的频道的节目内容。 例如，用户按压数字键“1”时，显示设备获得的第二频道号为1，第二频道号“1”的长度为1，将长度“1”与频道号最大长度“2”比较，显然第二频道号的长度小于频道号最大长度。
若用户再次按压数字键“2”，则显示设备获得的第二频道号为12，此时第二频道号“12”的长度为2，将长度“2”与预设最大长度“2”比较，显然第二频道号的长度等于预设最大长度，显示设备直接将第一频道节目内容切换为第二频道号12指示的频道的节目内容，提高用户的操作体验。并且，在第二频道号的长度等于预设最大长度时，用户在第一预设时长内按压数字键时，显示设备也不会响应，其中，第一预设时长例如可以为1s，具体数值本申请实施例不进行限定。从而避免用户由于误操作、用户长时间按压遥控器按键等原因导致第二频道号的长度大于预设最大长度，进而导致显示设备无法显示第二频道号对应的频道的情况。
图4A-4D中示例性示出了通过操作控制装置100而使显示设备200提供的一个GUI400的示意图。
在上述图1A-1D的基础上，需要说明的是：显示设备通常通过在其上显示EPG，使得用户可以利用EPG提供的菜单查看各个频道的节目(如：节目内容介绍、演员及导演的介绍等)，或者，预约录制未来的节目等。EPG用户界面以矩阵形式排列和显示广播节目，其通常采用二维模式显示频道和时间，并且以与广播节目的广播时间长度成比例的大小，显示组成EPG的各广播节目。
EPG显示的过程为：参照图1C，显示设备的调谐解调器210接收广播信号，解码器(图中未示出)从所接收的广播信号中提取EPG信息，并将所提取的EPG信息输出至内部总线；从而使控制器250将输出至内部总线的EPG信 息存储在存储器260中，以备显示EPG用户界面。
在显示设备的显示器275上，当前显示如图2所示的节目画面时，用户通过用户接口265发送的EPG显示请求信号输入至控制器250，例如：按压遥控器上EPG按键，也即，响应于用户发出的EPG显示请求，控制器250控制从存储器260中读取EPG信息，使得EPG生成器(图中未示出)可基于所读取的EPG信息来构建EPG，进而通过视频处理器270将图4A所示的EPG用户界面显示在显示器275上。
图4A是一种EPG用户界面的示意图。如图4A所示，垂直方向是频道轴方向，以多行形式显示频道列表中的多个频道，其中，选择器定位在EPG用户界面中的第一频道上，如图4A中的区域42所示；水平方向是时间轴方向，每行内各个广播节目以播放时间顺序排列，且各个广播节目的显示区域的大小表示其广播时间长度、显示区域的起始位置表示其起始播放时刻、显示区域的结束位置表示其终止播放时刻、以及显示区域内显示其节目名称。图4A中EPG用户界面内示出了五个频道(DC1-DC5)，每个频道的节目按照节目播放时间顺序排列显示为一行，如图4A中的区域41所示。例如：图4A示出了4:00PM到6:00PM之间的广播节目菜单，DC 1频道的广播节目10-13，DC2频道的广播节目20-25，DC 3频道的广播节目30-36，DC 4频道的广播节目40-48，DC 5频道的广播节目50-57。图4A中的区域43例如可以用来播放选择器选中的频道的节目内容。
需要说明的是，选择器的显示形式可以为焦点对象，焦点对象的标识形式不限。示例的，如图4A中通过设置项目背景颜色来实现或标识焦点对象的位置，也可以通过改变聚焦项目的文本或图像的边框线、尺寸、透明度和轮廓和/或字 体等标识焦点对象的位置。
在显示器显示图4A所示的画面后，用户通过按压遥控器上的可以组成频道号的按键，例如，数字键、“-”、“.”，向显示设备输入指示频道号信息的指令。参考显示设备在直播时切换频道的描述，用户通过按压遥控器的数字键“1”向显示设备输入指示频道号信息的指令，显示设备响应于指示频道号信息的指令，获得第二频道号1，并在图4A所示的界面上显示，获得如图4B所示界面；用户再次按压数字键“2”时，更新显示设备获得的第二频道号为12，如图4C所示，显示器上显示的第二频道号为12。
如果当前频道类型对应的频道号的最大长度为2，则在获得第二频道号后，显示设备直接更新图4C所示的EPG用户界面，获得如图4D所示的EPG用户界面，其中，如图4D所示，选择器定位在频道列表中第二频道号12指示的频道。并且，用户在第一预设时长内按压数字键时，显示设备也不会响应。
图5A-5D中示例性示出了通过操作控制装置100而使显示设备200提供的一个GUI400的示意图。
如图2所示，在显示设备的显示器上正在播放第一频道号指示的第一频道的内容时，例如，用户需要定位到一个频道上进行未来时间上该频道上节目内容预约时，用户可以通过按压遥控器上的“频道列表”键向显示设备输入频道列表显示请求指令，显示设备响应于该频道列表显示请求指令，如图5A所示，向显示器提供一GUI，该GUI为频道列表用户界面，在频道列表用户界面上，显示频道列表中多个频道，选择器定位在频道列表用户界面中的第一频道上，如区域44所示。
在显示器显示图5A所示的画面后，用户通过按压遥控器上的可以组成频道 号的按键，例如，数字键、“-”、“.”，向显示设备输入指示频道号信息的指令。参考显示设备在直播时切换频道的描述，用户通过按压遥控器的数字键“1”向显示设备输入指示频道号信息的指令，显示设备响应于指示频道号信息的指令，获得第二频道号1，并在图5A所示的界面上显示，获得如图5B所示界面；用户再次按压数字键“2”时，更新显示设备获得的第二频道号为12，如图5C所示，显示器上显示的第二频道号为12。
如果当前频道类型对应的频道号的最大长度为2，则在获得第二频道号后，显示设备直接更新图5C所示的EPG用户界面，获得如图5D所示的EPG用户界面，其中，如图5D所示，选择器定位在频道列表中第二频道号12指示的频道。并且，用户在第一预设时长内按压数字键时，显示设备也不会响应。
下面，对于显示设备在直播时切换频道，在EPG用户界面和频道列表用户界面上定位频道的三种模式，以显示设备在直播时切换频道为例进行说明，显示设备在EPG用户界面和频道列表用户界面上定位频道的相关描述可参考显示设备在直播时切换频道时对应的描述。
显示设备在每次接收到用户输入的指示频道号信息的指令时，会启动计时器，其中，若计时器的计时不是零，则清零重新开始计时。继续采用上面的例子，用户在按下数字键“1”后，计时器启动，且从零开始计时，由于第二频道号的长度为“1”，小于预设最大长度。如果用户在第二预设时长内没有按压组成频道号的按键，则在计时器记录的时长达到第二预设时长时，如图3C所示，显示设备将第一频道节目内容切换为第二频道号1指示的频道的节目内容。
并且，在显示设备获取到的第二频道号为“1”时，如果用户在第二预设时长内按压“OK”键，则显示设备接收到指示频道切换的指令，响应于用户输入的指 示频道切换的指令，如图3C所示，将显示器上显示的第一频道的节目内容切换为第二频道号1指示的频道的节目内容。
需要说明的是，如果频道号的预设最大长度为3位，在显示设备获得的第二频道号为1后，如用户在第二预设时长内按压数字键“2”，显示设备响应于用户输入的指示频道号信息的指令，获得第二频道号为12，计时器启动，且清零重新开始计时。
用户按压遥控器的按键向显示设备输入指示频道号信息的指令时，例如用户按下某个数字键时，可能按下按键后停留过长，遥控器会重复发送对应该按键的指示频道号信息的指令，例如，用户想要输入频道号123，由于用户再按键“1”上的按压时间过长，导致用户连续向显示设备输入与数字1对应的指示频道号信息的指令，例如，显示设备获得的第二频道号为111，如果显示设备的频道号的预设最大长度为3，则显示设备直接切换到与第二频道号111对应的节目内容，显然这不是用户想要观看的节目内容，导致用户体验差。
因此本申请实施例中，在遥控器监测到用户按压数字按键1的时长过长时，遥控器会先向显示设备发送该数字按键1，然后重复向显示设备发送该数字按键1并上报repeat属性，此时，显示设备可以在repeat属性为真时，忽略该操作，即显示设备仅在频道号内显示该一次1，而不是显示两次或多次1，这样可以防止用户误操作输入；显示设备可以在repeat属性为假时，即未接收到repeat属性时，才在频道号内显示一次1。
目前，显示设备获取的频道的类型分为多种频道类型，例如，频道类型可以分为有线电缆信号、卫星信号、天线信号。例如，有线电缆信号中的频道对 应的频道号为1-68，则其频道号最大长度为2位；卫星信号中的频道对应的频道号为1-237，则其频道号最大长度为3位。因此，不同的频道类型其频道号的最大长度不同。因此，显示设备需要获取每种频道类型的频道号的最大长度。
显示设备可以获取当前显示的频道对应的频道号，即获取与图2对应的第一频道号，根据第一频道号获取第一频道号对应的频道类型，根据频道类型，获取其对应的频道号的最大长度，从而将第二频道号与其所在的频道类型的频道号最的大长度进行比较。例如，对于有线电视，其频道号的最大长度为2，无线电视，其频道号的最大长度为3，如果用户观看有线电视对应的频道，在获得第二频道号后，将第二频道号的长度与2比较。
其中，显示设备例如可以在其开机时，遍历每个频道类型的频道列表，获取每个频道类型对应的频道号的最大长度并保存，以在获得第二频道号时，根据频道类型读取对应的最大长度。
图6A-6E示例性示出了显示设备中频道控制方法的流程图。
其中，图6A为显示设备切换频道时，频道控制方法，结合图6A所示的方法来说，该方法包括以下步骤S101～S104：
S101、显示器显示播放画面。例如，显示器可以显示图2所示的画面对应的视频内容。
S102、在接收用户输入指示频道号信息的指令的过程中，每接收到用户输入的一个指示频道号信息的指令，响应于用户输入的指示频道号信息的指令，获得第二频道号。例如，如图3A所示的画面，用户输入“1”时，在显示器提供的播放画面的右上角显示第二频道号1，用户继续输入“2”，更新第二频道号，获得的第二频道号为12，更新图3A所示的画面，获得图3B所示的画面。
S103、判断第二频道号的长度是否等于频道号的预设最大长度。
S104、若第二频道号的长度等于频道号的预设最大长度，则直接将显示器上显示的第一频道的节目内容切换为与第二频道号指示的频道的节目内容。例如，如图3C所示的画面。
本实施例中，用户在观看直播节目时切换频道，通过控制装置例如遥控器向显示设备输入组成频道号的频道号信息时，在用户输入的过程中，显示设备根据每次指示频道号信息的指令获得一个第二频道号，并判断第二频道号是否等于显示设备的频道号的最大长度，若是则直接将节目内容切换为第二频道对应的节目内容，而不要用户点击“OK”，或者等待一段时间后再切换，便于用户操作，提高用户的使用体验。
图6B为显示设备定位频道时，频道控制方法，结合图6B所示的方法来说，该方法包括以下步骤S201～S204：
S201、显示器显示EPG用户界面。例如，显示器可以显示图4A所示的画面。
其中，显示器播放图2所示的画面对应的视频内容时，用户通过遥控器上的“EPG”键向显示设备输入EPG显示请求指令，显示设备响应于该EPG显示请求指令，如图4A所示画面。
S202、在接收用户输入指示频道号信息的指令的过程中，每接收到用户输入的一个指示频道号信息的指令，响应于用户输入的指示频道号信息的指令，获得第二频道号。例如，如图4B所示的画面，用户输入“1”时，在显示器提供的播放画面的右上角显示第二频道号1，用户继续输入“2”，更新第二频道号，获得的第二频道号为12，更新图4B所示的画面，获得图4C所示的画面。
S203、判断第二频道号的长度是否等于频道号的预设最大长度。
S204、若第二频道号的长度等于频道号的预设最大长度，则直接更新EPG用户界面，且选择器选择频道列表中第二频道号指示的频道。例如，如图4D所示的画面。
图6C为显示设备定位频道时，频道控制方法，结合图6B所示的方法来说，该方法包括以下步骤S301～S304：
S301、显示器显示频道列表用户界面。例如，显示器可以显示图5A所示的画面。
其中，显示器播放图2所示的画面对应的视频内容时，用户通过遥控器上的“频道列表”向显示设备输入频道列表显示请求指令，显示设备响应于该频道列表显示请求指令，如图5A所示画面。
S302、在接收用户输入指示频道号信息的指令的过程中，每接收到用户输入的一个指示频道号信息的指令，响应于用户输入的指示频道号信息的指令，获得第二频道号。例如，如图5B所示的画面，用户输入“1”时，在显示器提供的播放画面的右上角显示第二频道号1，用户继续输入“2”，更新第二频道号，获得的第二频道号为12，更新图5B所示的画面，获得图5C所示的画面。
S303、判断第二频道号的长度是否等于频道号的预设最大长度。
S304、若第二频道号的长度等于频道号的预设最大长度，则直接更新频道列表用户界面，且选择器选择频道列表中第二频道号指示的频道。例如，如图5D所示的画面。
下面，对于显示设备在直播时切换频道，在EPG用户界面和频道列表用户界面上定位频道的三种模式，以显示设备在直播时切换频道为例进行说明，显 示设备在EPG用户界面和频道列表用户界面上定位频道的相关描述可参考显示设备在直播时切换频道时对应的描述。
S102之前，显示设备还需要判断接收到的指示频道号信息的指令是否为有效指令。具体的，结合图5D所示的方法来说，该方法包括以下步骤S401～S404：
S401、判断接收到的指令是否为指示频道号信息的指令。
具体的，显示设备接收的指令可能是指示频道切换的指令，例如，用户想要切换的频道为频道号1对应的频道，在按压数字键“1”后，由于第二频道号1的长度小于最大长度2，因此，显示设备不会直接切换频道。用户通过“OK”键输入指示频道切换的指令。因此，显示设备在接收到用户输入的指令后需要对指令进行判断，判断指令是否为指示频道号信息的指令。
S402、若接收到的指令为指示频道号信息的指令，获取指令属性信息，例如repeat属性，指令属性信息用于指示用户输入的指示频道号信息的指令是否为有效指令。
S403、在指令属性信息指示指示频道号信息的指令是有效指令时，响应于指示频道号信息的指令。
本实施例中，用户按压数字键时，如果用户在一数字键上按压的时长过长，导致显示设备频繁快速的接收到指示频道号信息的指令，显示设备通过与每条指示频道号信息的指令对应的指令属性信息，确定指示频道号信息的指令的有效性。在确定指示频道号信息的指令有效时，响应指示频道号信息的指令。从而避免用户在一数字键上按压的时长过长，导致显示设备切换后的节目内容并不是用户所要观看的节目内容的问题，提高用户体验。
图6E为本申请一实施例提供的频道控制方法，结合图6E所示的方法来说， 该方法包括以下步骤S501～S504：
S501、判断接收到的指令是否为指示频道号信息的指令，若是，执行S502；若否，执行S510。
S502、启动计时器，并判断计时器是否已有计时数据，若是，执行S503；若否，执行S504。
S503、计时器清零。
具体的，计时器清零后，执行S504。
S504、计时器计时。
S505、根据指示频道号信息的指令更新第二频道号，获得更新后的第二频道号。
S506、判断所述第二频道号的长度是否等于频道号的预设最大长度，若是，执行S507；若否，执行S508。
S507、显示设备进行频道切换或频道定位。
需要说明的是，若在执行S507前执行S509，则显示设备根据更新前的第二频道号进行频道切换或频道定位；若在执行S507之前执行S506或S509，则显示设备根据更新后的第二频道号进行频道切换或频道定位。例如，更新前的第二频道号为1，如果显示设备接收到的指令为指示频道切换的指令或指示频道定位的指令，则显示设备切换或定位到频道号1的频道；如果显示设备接收到的指令为指示频道号信息的指令，显示设备对第二频道号1进行更新，获得更新后的频道号12，且第二频道号12的长度达到最大长度，显示设备直接将频道切换或定位到频道号12对应的频道。
S508、判断在第二预设时长内，显示设备是否接收到用户输入的指令，若 是，返回S501，若否，执行S509。
S509、在计时时长等于或大于第二预设时长时，执行S507。
具体的，显示设获得的第二频道号为1时，频道号的长度小于最大长度，用户可以继续输入指示频道号信息的指令，或者指示频道切换的指令，如果显示设备在第二预设时长内接收到指令，返回执行S501。如果显示设备在第二预设时长内没有接收到任何指令，则在计时器的计时时长等于或大于第二预设时长时，执行S507。
S510、判断接收到的指令是否为指示频道定位的指令，若是，执行S507；若否，执行S503。
需要说明的是，若根据S510确定执行S503，则在执行完S503后结束程序。
上述实施例中，用户在观看直播节目时切换频道，通过控制装置例如遥控器向显示设备输入组成频道号的频道号信息时，在用户输入的过程中，显示设备根据每次指示频道号信息的指令获得一个第二频道号，并判断第二频道号是否等于显示设备的频道号的最大长度，若是则直接将节目内容切换为第二频道对应的节目内容，而不要用户点击“OK”，或者等待一段时间后再切换，便于用户操作，提高用户的使用体验。并且，由于在频道号的长度等于最大长度时，显示设备直接进行频道切换或频道定位，避免由于用户误操作导致频道号的长度大于最大长度而无法切换频道或定位频道的问题。
出于说明和描述的目的，提供了前述实施例，而非旨在穷举或限制本申请。具体实施例的各个元件或特征通常不限于该具体实施例，而是在适用情况下即使未具体示出或描述也可在所选实施例中使用或互换。同样也可以进行许多形 式变型，这种变型不被认为是脱离本申请所附的权利要求的范围，而且所有这样的修改被涵盖在本申请所附的权利要求的范围内。
