一种多画面分页播放方法
相关文件
本申请要求于 2013 年 01 月 10 日提交中国专利局、 申请号为 201310009344.4、 发明名称为"一种多画面分页播放方法"的中国专利申 请的优先权, 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及视频监控领域, 特别涉及一种视频监控中多个监控画面 的分页播放方法。 发明背景
目前, 一般的视频监控软件, 以及通过浏览器直接访问监控设备的 插件, 都提供了一种功能, 即多个视频通道同时在多个显示画面中播 放的功能 (包括预览或回放) 。 多画面播放一般是通过分屏方式实现 的, 即将显示屏进行分屏显示, 以分成多个画面进行播放, 例如: 1 分 屏(单画面), 即在一个显示屏中显示 1个画面; 4分屏(2x2 ) , 即在 一个显示屏中分成 4个屏幕区域, 如显示屏的左上、 右上、 左下、 右下 4个屏幕区域, 每个屏幕区域中各显示 1个画面, 一个显示屏中共可显 示 4个画面; 9分屏(3x3 ) , 即在一个显示屏中分成 9个屏幕区域, 如 显示屏以九宫格形式分成 9个屏幕区域, 每个屏幕区域中各显示 1个画 面, 一个显示屏中共可显示 9个画面。
如果软件支持的最大分屏数为 4 ( 4分屏), 而用户想要便捷地预览 16 个视频通道的播放画面时, 单靠分屏方式无法满足要求。 因此, 部 分软件提供了分页方式: 依据 16个视频通道的数量, 将显示屏设置为 4
分屏, 共分为 4页显示, 每页中各显示 4个视频通道的画面, 每页中显 示屏的左上、 右上、 左下、 右下 4个屏幕区域各显示 1个视频通道的画 面, 即第 1视频通道的画面、 第 2视频通道的画面、 第 3视频通道的画 面和第 4视频通道的画面在第 1页显示, 第 5视频通道的画面、 第 6视 频通道的画面、 第 7视频通道的画面和第 8视频通道的画面在第 2页显 示, 第 9视频通道的画面、 第 10视频通道的画面、 第 11视频通道的画 面和第 12视频通道的画面在第 3页显示, 第 13视频通道的画面、 第 14 视频通道的画面、 第 15视频通道的画面和第 16视频通道的画面在第 4 页显示, 用户通过翻页操作可快捷的预览各个视频通道的视频画面。 翻页可通过提供按钮或者滑动手势进行操作。
但是随着使用要求的提高, 现有的方法仍然存在不便之处, 比如: ( 1 )必须按顺序排列播放同一个设备中的所有视频通道的内容, 而 无法只播放同一个设备中的某几个视频通道的内容;
( 2 )播放的所有视频通道必须属于同一个设备, 而无法播放分属于 不同设备的多个视频通道的内容;
( 3 )当分页播放时, 无法切换分屏模式, 或者切换分屏模式后, 无 法翻页;
( 4 )在播放过程中无法关闭其中某个视频通道的播放。
因此, 对于多画面分页播放来说还有进一步改进之处。 发明内容
有鉴于此, 本发明提供一种多画面分页播放方法, 以实现对多个视 频通道画面的灵活操作。
本申请的技术方案是这样实现的:
一种多画面分页播放方法, 包括:
建立视频通道列表;
在所述视频通道列表中选择至少 1个视频通道;
根据所选择的视频通道个数和显示屏的分屏数, 确定所述显示屏的 分页数; 择的视频通道在各个分页的各个分屏中进行播放。
其中, 根据所选择的视频通道个数和显示屏的分屏数, 确定所述显 示屏的分页数, 依据如下公式进行
p=n/s+(n%s>0)
其中, n为视频通道个数, s为分屏数, p为分页数; (n%s>0)表示 为: 若 n除以 s的余数大于 0, 则 (n%s>0)=l ; 否则, (n%s>0)=0。
进一步, 当分屏数为 1 , 且所选择的视频通道个数为 1 时, 所述分 页数为 1 ; 当分屏数为 4, 且所选择的视频通道个数为 5至 8时, 所述 分页数为 2; 当分屏数为 4, 且所选择的视频通道个数为 9至 12时, 所 述分页数为 3。
进一步, 当在分屏数大于 1的情况下进行所选择的视频通道的播放 时:
当选取所播放视频通道中的任意一个视频通道时, 则将分屏数切换 为 1 , 并根据所选择的视频通道个数和切换后的分屏数, 重新确定显示 屏的分页数, 并将显示屏切换到所选取的该任意一个视频通道所在的 新的分页, 以进行所选取的该任意一个视频通道的播放。
进一步, 当关闭某一视频通道时, 若所关闭的视频通道的分屏画面 位于最后一个分页的最后一个分屏中, 且关闭该视频通道后, 所述最 后一个分页中仍有正在播放的其它视频通道的分屏画面, 则不进行关 闭该视频通道之外的其他操作。
进一步, 当关闭某一视频通道时, 若所关闭的视频通道的分屏画面 位于最后一个分页的最后一个分屏中, 且关闭该视频通道后, 所述最 后一个分页中不再有正在播放的其它视频通道的分屏画面, 则删除所 述最后一个分页, 并播放所删除的最后一个分页的前一分页的视频内 谷。
进一步, 当关闭某一视频通道时, 若所关闭的视频通道的分屏画面 并非位于最后一个分页的最后一个分屏中, 则将视频通道列表中所关 闭的视频通道之后的所有视频通道依次前移 1个分屏进行播放。
进一步, 当视频通道依次前移 1个分屏进行播放后, 若最后一个分 页中不再有正在播放的分屏画面, 则删除最后一个分页。
从上述方案可以看出, 与现有技术相比, 本发明的多画面分页播放 方法能够将所播放的视频通道与各分页、 各分屏的播放画面按顺序一 一对应, 以分页播放不同设备的多个视频通道, 进而实现了多设备视 频通道的集中播放, 并且利用本发明的方法在分页播放过程中可以切 换分屏模式, 切换分屏模式后, 按照新的分屏模式进行分页播放和翻 页操作, 符合用户的使用习惯。 另外, 利用本发明的方法进行分页播 放过程中, 可以关闭任意视频通道的播放, 关闭该任意视频通道的播 放后, 未关闭的视频通道与分屏画面仍能按顺序——对应。 与现有技 术相比, 本发明极大的增强了多画面分页播放控制的便利性。 附图简要说明

视频通道 03、 视频通道 04; 设备 B中同样包含有 4个视频通道, 分别 为视频通道 01、 视频通道 02、 视频通道 03、 视频通道 04。 本实施例 中, 以设备为一级节点并以视频通道为二级节点建立视频通道列表, 具体来说是以设备 A和设备 B为一级节点, 以设备 A和设备 B中的视 频通道为二级节点, 建立视频通道列表。
如图 2所示, 以复选框的形式在视频通道列表中选择 1个或者多个 视频通道进行视频播放, 例如图 2中选择了设备 A的视频通道 01、 设 备 A的视频通道 02、 设备 A的视频通道 03、 设备 A的视频通道 04以 及设备 B的视频通道 01、 设备 B的视频通道 03, 共 6个视频通道进行 视频播放。
需要说明的是, 视频通道列表的建立, 并不局限于上述方式, 总的 来说, 本发明是依据设备和 /或设备中的视频通道建立通道列表, 结合 不同的具体状况, 采用的方式可以不同。 比如, 可以仅以设备作为节 点建立视频通道列表, 此时当选中某一设备时, 该设备下的所有视频 通道即被选中, 例如以图 2中设备 A和设备 B作为节点, 而不以设备 A 中的各个视频通道和设备 B中的各个视频通道作为节点, 则当选中设备 通道即被选中; 比如, 可以以某一 /些设备中的视频通道和其它设备共 同作为节点, 而其它设备中的视频通道不作为节点, 建立视频通道列 表, 此时当选中某一 /些设备时, 该某一 /些设备下的所有视频通道即被 选中, 例如以图 2中设备 A的视频通道 01、 设备 A的视频通道 02、 设 备 A的视频通道 03、 设备 A的视频通道 04以及设备 B共同作为节点, 此时可以对设备 A的 1个视频通道或者设备 A的多个视频通道分别独立 的进行选择, 而当选择设备 B时, 则设备 B的所有视频通道便被选中, 设备 B的各个视频通道不能分别独立的进行选择。
本发明中所述的设备是指包含 1路或者 1路以上视频通道的视频采 集设备和 /或视频存储设备; 其中, 视频采集设备例如摄像机等, 视频 存储设备例如硬盘录像机等。
本发明利用所建立的视频通道列表, 对多个设备以及多个设备中的 多个视频通道进行统一管理, 随后的多画面分页播放仅针对视频通道 列表中所选择的设备以及视频通道进行操作, 而不再绕过视频通道列 表而直接针对各个设备进行独立操作。 本发明中所建立的视频通道列 表可以认为是一个对所有设备以及视频通道进行统一管理的虚拟设备 或装置, 这样便可认为是仅针对该虚拟设备或装置所提供的视频通道 进行播放, 从而实现对各个实体设备 (包含 1路或者 1路以上视频通道 的视频采集设备和 /或视频存储设备 )所提供视频的统一播放操作。
随后, 根据所选择的视频通道个数和显示屏的分屏数, 确定显示屏 的分页数。
首先, 根据视频通道列表中所选择的视频通道个数 n (例如图 2中, n=6 )切换为最适合的分屏模式 s。 例如, 在所支持的最大分屏数 Smax 为 4个, 即 4分屏的情况下, 当在视频通道列表中所选择的视频通道个 数为 n=l时, 则切换为 1分屏模式(s=l ) ; 当在视频通道列表中所选 择的视频通道个数为 η>1时, 则切换为 4分屏模式( s=4 ) 。
然后根据当前分屏模式 s和视频通道列表中所选择的视频通道个数 n计算分页数 p, 其中
p=n/s+(n%s>0)
其中, n为视频通道个数, s为分屏数, p为分页数。 (n%s>0)表示 为: 若 n除以 s 的余数大于 0, 则 (n%s>0)=l , 此时 p=n/s+l ; 否则, (n%s>0)=0, 此时 p=n/s。
例如, 当分屏数为 1 , 且所选择的视频通道个数为 1时, 分页数为
1; 当分屏数为 4, 且所选择的视频通道个数为 5至 8时, 分页数为 2; 当分屏数为 4, 且所选择的视频通道个数为 9至 12时, 分页数为 3。 以 此类推。
之后, 根据所选择的视频通道在视频通道列表中的顺序, 依次将所 选择的视频通道在各个分页的各个分屏中进行播放。
例如, 在图 2的视频通道列表中所选择的视频通道个数为 6, 则当 分屏数为 4 (即 4分屏) 时, 各个视频通道的播放位置如图 3A所示, 当分屏数为 1 ( 1分屏) 时各视频通道的播放位置如图 3B所示。
图 3A中, 依据通道个数 6和分屏数 4, 将显示屏的分页确定为 2 页, 分别为分页 P1和分页 P2, 将各个视频通道依据视频通道列表中的 顺序在分页 P1和分页 P2中的各个分屏中进行播放, 即将图 2所示的设 备 A的视频通道 01在分页 P1中的分屏 1 (左上)中播放, 将设备 A的 视频通道 02在分页 P1中的分屏 2 (右上) 中播放, 将设备 A的视频通 道 03在分页 P1 中的分屏 3 (左下) 中播放, 将设备 A的视频通道 04 在分页 P1中的分屏 4 (右下) 中播放, 将设备 B的视频通道 01在分页 P2中的分屏 1 (左上)中播放, 将设备 B的视频通道 03在分页 P2中的 分屏 2 (右上) 中播放。
图 3B 中, 依据通道个数 6和分屏数 1 , 将显示屏的分页确定为 6 页, 分别为分页 Pl、 分页 P2、 分页 P3、 分页 P4、 分页 P5和分页 P6, 将各个视频通道依据视频通道列表中的顺序在分页 P1至分页 P6中进行 播放, 即将图 2所示的设备 A的视频通道 01在分页 P1中播放, 将设备 A的视频通道 02在分页 P2中播放, 将设备 A的视频通道 03在分页 P3 中播放, 将设备 A的视频通道 04在分页 P4中播放, 将设备 B的视频通 道 01在分页 P5中播放, 将设备 B的视频通道 03在分页 P6中播放。
计算好分屏模式、 分页数、 视频通道列表中所选择的视频通道与分
屏画面之间的对应关系后, 即开始播放。 首先显示分页 Pl。 用户可通 过翻页操作(例如, 可通过按钮或滑动手势进行翻页操作) , 依次切换 到分页 P2、 分页 P3等, 以预览多画面播放。 如图 4A所示的 6视频通 道和 4分屏的翻页操作, 以及图 4B所示的 6视频通道和 1分屏的翻页 操作。
本发明在播放过程中可以切换分屏模式, 切换后按照新的分屏模式 进行分页播放。 例如, 当在分屏数大于 1的情况下进行所选择的视频通 道的播放时: 当选取所播放视频通道中的任意一个视频通道时, 则将 分屏数切换为 1 , 并根据所选择的视频通道个数和切换后的分屏数, 重 新确定显示屏的分页数, 并将显示屏切换到所选取的该任意一个视频 通道所在的新的分页, 以进行所选取的该任意一个视频通道的播放。 以下, 以在分屏数为 4的情况下, 将分屏数切换为 1的过程为例进行介 绍, 当在分屏数大于 1的其它情况, 可依据以下介绍同样将分屏数切换 为 1 , 对于其它具体情况的切换过程, 不再赘述。
如图 5所示, 视频通道列表中的视频通道个数为 6, 最大分屏数为 4, 当前为 4分屏模式, 正在播放分页 P1 , 可通过双击或展开手势等触 摸分屏 4 (正在播放视频通道列表中的第 4个视频通道的画面) , 以切 换为 1 分屏模式, 依据切换后的分屏数 1 重新确定显示屏的分页数为 6, 之后切换到 1分屏模式的第 4页进行播放(对应于 4分屏模式中的 分页 P1的分屏 4 )。 之后, 用户可在该新的分页、 分屏模式下进行翻页 操作。 图 5中虚线框标注当前正在播放的分页。
本发明在分页播放过程中可以关闭某分屏画面对应视频通道的播 放, 关闭后, 视频通道列表与分屏画面仍能按顺序——对应。 关闭过 程分为以下两种情况。
( 1 )当关闭某一视频通道时, 若所关闭的视频通道的分屏画面位于
最后一个分页的最后一个分屏中, 且关闭该视频通道后, 最后一个分 页中仍有正在播放的其它视频通道的分屏画面, 则不进行关闭该视频 通道之外的其他操作。
例如, 如图 6A所示, 若关闭的视频通道的分屏画面位于最后一个 分页的最后一个分屏中, 此时不需采取任何操作即可保证关闭该视频 一对应。 图 6A中视频通道列表中的视频通道个数为 6, 当前为 4分屏 模式, 正在播放分页 P2, 此时如果关闭其中的分屏画面 6所播放的视频 通道, 则不需进行关闭该视频通道之外的任何操作。 图 6A中虚线框标 注为当前正在播放的分页。
当关闭某一视频通道时, 若所关闭的视频通道的分屏画面位于最后 一个分页的最后一个分屏中, 且关闭该视频通道后, 最后一个分页中 不再有正在播放的其它视频通道的分屏画面, 则删除最后一个分页, 并转为播放所删除的最后一个分页的前一分页的视频内容。
例如, 如图 6B所示, 视频通道列表中的视频通道个数为 5 , 当前为 4分屏模式, 正在播放分页 P2, 此时如果关闭其中的分屏画面 5所播放 的视频通道, 则此时分页 P2已无播放画面, 因此分页 P2被删除, 转为 播放分页 Pl。 图 6B中虚线框标注当前正在播放的分页。
( 2 )当关闭某一视频通道时, 若所关闭的视频通道的分屏画面并非 位于最后一个分页的最后一个分屏中, 则将视频通道列表中所关闭的 视频通道之后的所有视频通道依次前移 1个分屏进行播放。
例如, 如图 7A所示, 视频通道列表中的视频通道个数为 6, 当前 为 4分屏模式, 正在播放分页 P1 , 此时如果关闭其中的分屏画面 4, 则 原分展画面 5的视频通道前移到分展画面 4进行播放, 原分展画面 6的 视频通道前移到分屏画面 5进行播放。 图 7A中虚线框中为当前正在播
放的页。
在视频列表中, 当视频通道依次前移 1个分屏进行播放后, 若最后 一个分页中不再有正在播放的分屏画面, 则删除最后一个分页。 删除 最后一个分页后, 转为播放所删除的最后一个分页的前一个分页。 例 如如图 7B所示, 视频通道列表中的视频通道个数为 5 , 当前为 4分屏模 式, 正在播放分页 P1 , 此时如果关闭分屏画面 3 , 则原分屏画面 4的视 频通道前移到分屏画面 3进行播放, 原分屏画面 5的视频通道前移到分 屏画面 4进行播放, 此时分页 P2已无播放画面, 因此分页 P2被删除, 转为播放分页 Pl。 图 7B中虚线框中为当前正在播放的页。
基于上述多画面分页播放方法, 本发明提供了一种终端, 作为一个 实施例, 该终端为手机。 如图 8所示, 该终端包括: 视频通道列表建立 模块, 用于建立视频通道列表; 视频通道选择模块, 用于在所述视频 通道列表中选择至少 1个视频通道; 分页模块, 用于根据所选择的视频 通道个数和显示屏的分屏数, 确定所述显示屏的分页数; 播放模块, 的视频通道在各个分页的各个分屏中进行播放。
其中, 根据所选择的视频通道个数和显示屏的分屏数, 确定所述显 示屏的分页数, 依据如下公式进行
p=n/s+(n%s>0)
其中, n为视频通道个数, s为分屏数, p为分页数; (n%s>0)表示 为: 若 n除以 s的余数大于 0, 则 (n%s>0)=l ; 否则, (n%s>0)=0。
如图 8所示, 该终端包括: 信号接收模块 2, 用于接收至少 1个设 备的视频信号, 并发送给控制模块 1 ; 显示模块 3 , 用于播放控制模块 1 处理后的视频通道的内容; 输入模块 4, 用于选择视频通道。 其中, 每 个所述设备至少具有 1个视频通道。
本发明中, 视频通道列表建立模块、 视频通道选择模块、 分页模块 和播放模块内置于控制模块 1中, 进而实现在终端(例如手机) 中的多 画面分页播放。
