摘要： Systems and methods for template-based multimedia authoring and sharing are described. In one aspect, media content is selectively applied to a content description template to author media in a content description. The content description template provides a temporal structure for the applied media content. A content representation template is selected and combined with the temporally structured media in the content description to specify rendering criteria and generate a content description and representation for one or more of rendering, sharing, and exporting the temporally structured authored media.

摘要： Systems and methods are described for creating a video booklet that allows browsing and search of a video library. In one implementation, each video in the video library is divided into segments. Each segment is represented by a thumbnail image. Signatures of the representative thumbnails are extracted and stored in a database. The thumbnail images are then printed into an artistic paper booklet. A user can photograph one of the thumbnails in the paper booklet to automatically play the video segment corresponding to the thumbnail. Active shape modeling is used to identify and restore the photo information to the form of a thumbnail image from which a signature can be extracted for comparison with the database.

摘要： Generation, coding and transmission of an effective video form, scalable portrait video. As an expansion to bi-level video, portrait video is composed of more gray levels, and therefore possesses higher visual quality while it maintains a low bit rate and low computational costs. Portrait video is a scalable video in that each video with a higher level always contains all the information of the video with a lower level. The bandwidths of 2–4 level portrait videos fit into the bandwidth range of 20–40 Kbps that GPRS and CDMA 1X can stably provide. Therefore, portrait video is very promising for video broadcast and communication on 2.5 G wireless networks. With portrait video technology, this system and method is the first to enable two-way video conferencing on Pocket PCs and Handheld PCs.

摘要： Computer-implemented methods for power management of network interface devices are disclosed. Such methods may include dividing a time period into a plurality of time slots, determining an amount of data received by the network interface device during a first of the time slots, and determining whether the amount of data received exceeds a predefined threshold. If the amount of data received exceeds the predefined threshold, then the network interface device is caused to be awake during a subsequent time slot. The network interface device is caused to go to sleep during the subsequent time slot unless the amount of data received exceeds the predefined threshold. A number of the time slots may be defined as wakeup time slots during which the network interface device is awake. The number of time slots during the time period in which one or more packets were received by the network interface device may be compared to the number of wakeup time slots during the time period. Based on the comparison, the number of wakeup time slots may be adjusted for a subsequent time period.
摘要翻译：公开了用于网络接口设备的电源管理的计算机实现的方法。这样的方法可以包括将时间段划分为多个时隙，确定网络接口设备在第一时隙期间接收的数据量，以及确定所接收的数据量是否超过预定阈值。如果接收到的数据量超过预定阈值，则在后续时隙中使网络接口设备唤醒。使网络接口设备在随后的时隙中进入休眠状态，除非接收到的数据量超过预定义的阈值。多个时隙可以被定义为网络接口设备唤醒期间的唤醒时隙。可以将网络接口设备接收到一个或多个分组的时间段内的时隙数与该时间段内的唤醒时隙数进行比较。基于该比较，可以随后的时间段调整唤醒时隙的数量。

摘要： A video compression/decompression procedure that provides a reliable, low bit video bit stream with some color features over relatively low bandwidth wireless networks. The procedure provides some pleasing color features in a video bit stream without needing a large bandwidth network like those needed for example for a MPEG 4 bit stream. The procedure provides the color features by using a bi-level Y luminance component and a number of UV chrominance combinations. The bi-level Y-component outlines the features of the image, while the UV-combinations describe the basic color information of the image.

摘要： Systems and methods for variable block size early termination for video coding are described. In one aspect a set of thresholds are selected based on block sizes in a video encoding scheme. The thresholds include a respective threshold for each block size used by the encoding scheme. For each macroblock of multiple macroblocks in a video data sequence, blocks in the macroblock are evaluated in view of respective threshold(s) to determine if motion estimation operations can be terminated prior to evaluating remaining blocks in the macroblock.

摘要： Video coding methods and apparatuses are provided that make use of various models and/or modes to significantly improve coding efficiency especially for high/complex motion sequences. The methods and apparatuses take advantage of the temporal and/or spatial correlations that may exist within portions of the frames, e.g., at the Macroblocks level, etc. The methods and apparatuses tend to significantly reduce the amount of data required for encoding motion information while retaining or even improving video image quality.

摘要： The techniques and mechanisms described herein are directed to controlling communication paths between conference members in a decentralized multi-party conference that supports a full mesh architecture. Several check points are tested in order to handle concurrency issues and to ensure quality of service. First, a check is made to determine whether any pending communication paths exist between the two systems. Second, a check is made to determine whether one of the systems is in the process of leaving the multi-party conference. Third, a check is made to determine whether a maximum number of conference members already exist in the conference. Upon failing any of these checks, the communication path between the two systems fails. Upon success, the new system initiates the joining process with each of the other members in the conference in order to maintain the full mesh architecture.

摘要： A coding framework that provides conversions between one or more video formats without the use of a transcoder. A video information stream that includes color information formatted in accordance with a first color space sampling format is split into a base stream and an enhanced stream. The base stream is formatted in accordance with a second color space sampling format. The enhanced stream includes enhanced information that when combined with the base stream re-constructs the first format. During encoding, the enhanced stream may be encoded using spatial information related to the base information stream. An output stream of the encoded base stream and encoded enhanced stream may be interleaved, concatenated, or include independent files for the encoded base stream and the encoded enhanced stream.
