摘要： A video encoding acceleration service to increase one or more of the speed and quality of video encoding is described. The service acts as an intermediary between an arbitrary video encoder computer program application and arbitrary video acceleration hardware. The service receives one or more queries from the video encoder to identify implementation specifics of the video acceleration hardware. The service interfaces with the video acceleration hardware to obtain the implementation specifics. The service communicates the implementation specifics to the video encoder. The implementation specifics enable the video encoder to: (a) determine whether one or more of speed and quality of software encoding operations associated with the video encoder can be increased with implementation of a pipeline of one or more supported encoding pipeline configurations and capabilities, and (b) implement the pipeline by interfacing with the service.

摘要： Assessment of de-interlaced video quality is determined automatically by de-interlacing interlaced video content using a reference de-interlacer and a test de-interlacer. The reference de-interlacer produces a result of known quality and the test de-interlacer is one which is being assessed. The result from each de-interlacer is compared to reference video content to derive a signal-to-noise ratio for each relative to the reference video content. The difference in the signal-to-noise ratios is compared against a predefined threshold. If the difference is within the range defined by the threshold, the test de-interlacer is determined to produce an acceptable product.
摘要翻译：去隔行视频质量的评估通过使用参考解交错器和测试去隔行扫描器的隔行扫描视频内容自动确定。参考去隔行器产生已知质量的结果，并且测试去隔行器是正在评估的解交织器。将每个去隔行器的结果与参考视频内容进行比较以导出每个相对于参考视频内容的信噪比。将信噪比的差异与预定阈值进行比较。如果差值在由阈值限定的范围内，则确定测试去隔行器产生可接受的产品。

摘要： Embedded scalar quantizers for compression are described, along with tools for corresponding decompression. For example, a codec uses an embedded dead zone plus uniform threshold quantizer with repeated division of steps by specific factors. Non-dead-zone steps at a current level are divided into m+1 non-dead-zone steps at the next higher level, and the dead zone at the current level is divided into a dead zone at the next higher level with n new non-dead-zone steps at each side. Values for m and n depend on implementation. In some implementations, m=2 and n=1, and the dead zone ratio z=1, but other values are possible.

摘要： A system identifies video data to be encoded as well as multiple display regions associated with a particular video display type. Each of the multiple display regions is associated with a different portion of an image associated with the video data. The video data is encoded such that the encoded video data includes information regarding the multiple display regions. Each of the multiple display regions has an associated display region identifier. Additionally, the system may identify an active region of the video data. The active region may be located anywhere within an image associated with the video data. The video data is encoded such that the encoded video data includes information regarding the active region.

摘要： A first frame of data is encoded and a first timestamp associated with the first frame of data is generated. The first timestamp includes complete timing information. The first frame of data and the associated first timestamp is transmitted to a destination. A second frame of data is encoded and a second timestamp associated with the second frame of data is generated. The second timestamp includes a portion of the complete timing information. The second frame of data and the associated second timestamp is then transmitted to the destination. Additional frames of data are encoded and additional timestamps associated with the additional frames of data are generated. The majority of the additional timestamps include a portion of the complete timing information.

摘要： Timecoding systems, methods and data structures are described which, in some embodiments, permit a true time to be ascertained from media samples whose timecodes contain an amount of drift which can arise from having non-integer frame rates. Inventive methods incorporate the use of an offset parameter that describes a time difference between a timecode and a true time associated with a media sample. The inventive approaches can be incorporated with and used compatibly in connection with current timecoding paradigms such as SMPTE timecode and the like. Further embodiments permit timecoding to take place at the field level of a frame. This can permit true-time calculations to be done to ascertain the true time associated with individual fields of a frame. In addition, other embodiments provide novel counting compensation methods that are directed to reducing the drift that can be associated with media samples that are sampled at non-integer frame rates.

摘要： A content control system for limiting access by sensitive users, such as children, or the like, to certain types of content. The content control system provides a user interface for an information handling system, information appliance, content recorder, or the like that provides a single point of user control for parental locks for multiple audio and/or audiovisual devices. In embodiments of the invention, the content control system may employ a method of setting the content rating parameters of a content control system based on content rating of example content. The content control system may also employ a method for modifying the content rating of content received by a content recorder such as a personal video recorder, or the like.
