摘要： Methods, systems, and computer readable media can be operable to facilitate the detection and management of a filler region during trickplay of a content stream. A filler region at the edge of a targeted advertisement segment may be detected based on the presence of one or more consecutive I-frames. When a filler region is detected during a trickplay operation, a corrective method may be applied during trickplay of the filler region. The corrective method may include a modification of a frame skip count (FSC) and/or frame repeat count (FRC) during trickplay of the filler region, or may include skipping over the processing and output of filler frames during trickplay of the filler region. An index file may be modified to include an indication of a designation of one or more frames as either a filler frame or non-filler frame.

摘要： Methods, systems, and computer readable media can be operable to facilitate the detection of a closed caption standard and corresponding extraction of closed caption data according to the detected closed caption standard. A set-top box (STB) may receive content from multiple different networks and/or service providers, and closed caption data may be formatted differently in content received from the various networks and/or service providers. The STB may identify a relevant standard with which to process closed caption data in a received content stream based upon an identification of the network and/or provider from which the content stream is received, and the STB may extract and render closed caption data using a process associated with the identified network and/or provider.
摘要翻译：方法，系统和计算机可读介质可以操作以便于根据检测到的隐藏字幕标准来检测隐藏字幕标准和相应的隐藏字幕数据的提取。机顶盒（STB）可以从多个不同网络和/或服务提供商接收内容，并且在从各种网络和/或服务提供商接收的内容中可以对不同的封闭字幕数据进行格式化。 STB可以基于从其接收内容流的网络和/或提供商的标识来标识用于处理接收的内容流中的隐藏字幕数据的相关标准，并且STB可以使用与所识别的网络和/或提供者相关联的过程。

摘要： A system is provided for providing a trickplay operation using a digital video recorder (DVR) when the video includes Broadcom Transport Packets (BTPs) designed for MPEG-2, but in an MPEG-4 video steam. In a first implementation, to enable trickplay to function properly with MPEG-4 video, the BTP descriptors included with each group of data frames are disabled so that a single descriptor provided without BTPs that would otherwise be provided in MPEG-4 is all that remains. In a second implementation, the 5 descriptors for MPEG-4 are combined into a single descriptor. In a third implementation, the pace of decoding of the MPEG-4 descriptors is increased so that the speed of encoding all the 5 descriptors is comparable to the pace of decoding a single MPEG-2 descriptor.
摘要翻译：提供一种系统，用于当视频包括为MPEG-2设计的Broadcom传输数据包（BTP），但MPEG-4视频流时，使用数字视频录像机（DVR）提供特技播放操作。在第一实现中，为了使特技播放能够使用MPEG-4视频正常工作，包含在每组数据帧中的BTP描述符被禁用，使得没有提供否则将在MPEG-4中提供的BTP的单个描述符全部保留。在第二实现中，用于MPEG-4的5个描述符被组合成单个描述符。在第三实施方式中，增加了MPEG-4描述符的解码速度，使得所有5个描述符的编码速度与解码单个MPEG-2描述符的速度相当。
