    • Systems and methods for transitioning from buffering video to recording video. The control application receives a video and causes the video to be buffered until it detects a buffer full condition. Upon receiving the buffer full condition, the control application causes the media recorder to begin recording the newly received video as a recording, and designates the buffered video as part of the recording. In one method, the control application can be set to either record or play when the buffer becomes full. In other methods, the control application prompts the user for input indicating whether the video should be recorded or played when the buffer becomes full. In still other methods, the control application alerts the user as to how long a program may be paused before the buffer will become full.
    • 从缓冲视频转换到录像的系统和方法。 控制应用程序接收视频并使视频缓冲,直到检测到缓冲区满状态。 在接收到缓冲器满状态时,控制应用程序使媒体记录器开始记录新接收的视频作为记录,并且将缓冲的视频指定为记录的一部分。 在一种方法中,当缓冲器变满时,可以将控制应用设置为记录或播放。 在其他方法中,控制应用程序提示用户输入,指示当缓冲区已满时,是否应录制或播放视频。 在其他方法中,控制应用程序向用户通知在缓冲区变满之前程序可能暂停多长时间。

    • Systems and methods for managing the storage of recordings in a recording device in which the recordings were requested by several users are provided. Each user may be assigned a storage space limit defining the amount of storage space each user is entitled to use. In some embodiments, the storage space limit may be flexibly increased to take advantage of extra space available from other users. The system may intelligently borrow space from other users to limit the risk that a requested recording is canceled due to unavailable storage resources. In some embodiments, the system may jointly allocate a recording to several users who commonly requested a recording. The system may also set aside space in the recording device that is saved exclusively for a particular user. In some embodiments, the recording device may allocate the storage resources based on the usage of the recordings.
    • 提供了用于管理在多个用户请求记录的记录装置中记录的存储的系统和方法。 可以为每个用户分配限定每个用户有权使用的存储空间量的存储空间限制。 在一些实施例中,可以灵活地增加存储空间限制以利用来自其他用户的额外空间。 系统可以智能地从其他用户借用空间,以限制由于不可用的存储资源而要求的记录被取消的风险。 在一些实施例中,系统可以共同地将记录分配给通常请求记录的多个用户。 系统还可以在专门为特定用户保存的记录装置中留出空间。 在一些实施例中,记录设备可以基于记录的使用来分配存储资源。

    • Systems and methods for rewinding a video to a point before the video was first viewed. Video transmitted by a media source is cached by a remote server. Upon a trick-play request for the video, the server generates a rewind stream that includes the video that was transmitted by the media source before the user started to view the video. Upon receiving the rewind stream, the user's equipment may cache the rewind stream in a rewind buffer and rewind or play from the rewind buffer. The server may also generate and transmit a forward stream of the video that the media source has not yet transmitted. The user's equipment may cache the forward stream in a forward buffer. To perform trick-play operations with the video, the user's equipment may migrate the playback of the video to the rewind and forward buffers and rewind or fast-forward the video from the buffers.
    • 将视频倒转到视频首次观看之前的系统和方法。 由媒体源发送的视频由远程服务器缓存。 在对视频进行特技播放请求时,服务器产生包括在用户开始观看视频之前由媒体源发送的视频的倒带数据流。 在接收到倒带流时,用户的设备可以将快退流缓存在倒带缓冲器中并从倒带缓冲器进行倒带或播放。 服务器还可以生成和发送媒体源尚未传送的视频的前向流。 用户的设备可以将前向流缓存在前向缓冲区中。 为了用视频执行特技播放操作,用户的设备可以将视频的回放迁移到倒带和转发缓冲器并且从缓冲器中倒带或快进视频。

    • Systems and methods for displaying substitute media while fast forwarding past advertisements are provided. When a user reaches the advertisement, the interactive media guidance application may receive an instruction to fast forward the advertisement. In response to the fast forward instruction, the interactive media guidance application may identify and display substitute media instead of the advertisement. The substitute media may be an image, a video frame/clip, a graphic, an animated graphic, or any other suitable media. The substitute media may be distributed in the advertisement using any suitable method. For example, the substitute media may be incorporated in the video frames of the advertisement (e.g., overlaid in the video frames of the advertisement), added as hidden video frames distributed in the advertisement, or any other suitable approach. An advertisement tool for creating advertisements that include substitute media, and for previewing advertisements as they are fast forwarded is also provided.
    • 提供了在快速转发广告时显示替代媒体的系统和方法。 当用户到达广告时,交互式媒体引导应用可以接收快速转发广告的指令。 响应于快进指令,交互式媒体引导应用可以识别和显示替代媒体而不是广告。 替代媒体可以是图像,视频帧/剪辑,图形,动画图形或任何其它合适的媒体。 替代媒体可以使用任何合适的方法分发在广告中。 例如,替代媒体可以被并入广告的视频帧(例如,叠加在广告的视频帧中),作为在广告中分配的隐藏视频帧添加,或者任何其他合适的方法。 还提供了用于创建包括替代媒体的广告以及用于在快速转发时预览广告的广告工具。
