摘要： Online video can now be supplied with hyperlinks that are associated with and move with objects in the video. However, online video players tend not to report an accurate frame number, and this results in poor synchronisation of the movement of the hyperlink and the object. We propose that a subset of the pixels in the frame be used to encode a numeric frame identifier.

摘要翻译： 在线视频现在可以提供与视频中的对象相关联并与其移动的超链接。 然而，在线视频播放器倾向于不报告准确的帧号，并且这导致超链接和对象的移动的同步不良。 我们建议使用帧中的像素的子集来对数字帧标识符进行编码。

摘要： Provided are apparatuses and methods in a digital broadcast transmission system for transmitting a notification from a transmitter to a receiver or subscriber station. The notification may inform the user or subscriber of information regarding upcoming events, programs or services, changes to existing events, programs or services, advertisements, emergency announcements, and the like. In one example, a parameter is included in the ESG fragment transmitted to a receiver for indicating that the service associated with the ESG fragment is a notification. In another example, the ESG fragment is an access fragment containing a type parameter for indicating that the notification associated with the access fragment is a component of the corresponding service.

摘要： Methods of preserving captioning information in an input video stream through transcoding of the input video stream include extracting caption data from the input video stream, translating the caption data into at least one output caption format, packaging the translated caption data into data packets for insertion into a video stream, synchronizing the packaged caption data with a transcoded version of the input video stream, receiving a preliminary output video stream that is a transcoded version of the input video stream, and combining the packaged caption data with the preliminary output video stream to form an output video stream. Related systems and computer program products are also disclosed.
