    Abstract: A video processing system is operable to perform one or more display queue trick (DQT) operations utilizing decoded frames queued in memory. The decoded frames are generated from the start of random access points (RAPs) in frame segments in an encoded video stream. Location of RAPs may be determined during decoding of the encoded video stream. Exemplary encoding scheme comprise MPEG, AVC and/or VC1. The DQT modes include forward and/or reverse display modes. The used frames are selected based on determination of DQT mode parameters, queuing limitations and/or frame properties of selected and/or unselected frames in the frame segments. Frame properties comprise frame discardability and/or display inter-frame dependencies between selected and/or unselected frames. The video processing system is operable to jump to preceding and/or subsequent RAPs during DQT mode operations. The video processing system is also operable to skip one or more RAPs during such jumps.

    Abstract: A user at a client machine can customize components of a database search performed at a server. The user does this by sending executable code to the database server. Software code runs as middleware on the database server machine to communicate between the database server and the client and performs the functions of supplying the client with vital information required for generating code which will be used for customizing various processes of the database retrieval session. Typically, the server comprises a set of database servers and the middleware runs on each database server machine to communicate between the database servers and the client. The middleware provides a virtual machine on which the user-supplied code written in a virtual machine language is executed, giving a uniform interface across the set of database servers on which the same user-supplied code will be executed ensuring that the user-supplied code executes under database server specified access privileges.

    Abstract: A methodology of highly interactive intra-object relevance feedback is used to retrieve multimedia data from a database. The query object could consist of one or more images, images derived from video, a video sequence, or an audio clip. The query is adjusted using the information fed-back by the user about the relevance of previously extracted part(s) from the object itself, such that the adjusted query is a better approximation to the user's perception. The information fed-back by the user during intra-query modification is used for intra-object learning of the user's perception. The refined query is subsequently used for inter-object relevance feedback where data is retrieved from the database based on parameters learnt by intra-query object feedback mechanism, and the user provides feedback by ranking the retrieved objects in order of their relevance to him or her. In the system according to the invention, inter-object learning of user's perception is expedited by utilizing the learnt parameters in the intra-object relevance feedback. Furthermore, the methodology of the invention allows for building refined queries based on part(s) or sub-sequence(s) of the query object rather than the entire object itself, thereby reducing the number of irrelevant objects, retrieved from the database. The methodology allows synthesis and modification of the input query object itself in the event a query object is not directly available, and, also to learn the user's perception.

    Abstract translation: 高度交互的对象内相关反馈的方法用于从数据库检索多媒体数据。 查询对象可以包括一个或多个图像，从视频，视频序列或音频剪辑导出的图像。 使用用户反馈的关于先前提取的部分与对象本身的相关性的信息来调整查询，使得经调整的查询更好地逼近用户的感知。 用户在查询修改期间反馈的信息用于用户感知的对象内学习。 精确查询随后用于对象间相关性反馈，其中基于由查询内对象反馈机制学习的参数从数据库检索数据，并且用户按照与他或她的相关性的顺序对所检索的对象进行排序来提供反馈 。 在根据本发明的系统中，通过利用对象内相关性反馈中的学习参数来加快用户感知的对象间学习。 此外，本发明的方法允许基于查询对象的部分或子序列而不是整个对象本身构建精简查询，从而减少从数据库检索的不相关对象的数量。 该方法允许在查询对象不直接可用的情况下对输入查询对象本身进行合成和修改，还可以了解用户的感知。

    Abstract: Systems, methods, and apparatuses are provided for concealing errors in video data. It is detected whether a slice group in a picture contains errors. When the slice group contains errors and the picture is not a first intra-picture following a channel change, the slice group in the picture is replaced with a slice group of a most recent intra-coded picture. When the slice group contains errors and the picture is the first intra-picture following the channel change, the slice group is replaced with black pixels.
