摘要： A graphic user interface is provided to facilitate a playback of a movie from any desired point. The graphic user interface includes a track bar to reflect how much time data pertaining to the movie title is available for playback. After it is determined that a current data point is being dragged along the track bar, a time corresponding to the current data point is tracked as such a subsequent playback of the movie starts right from the current data point. In one embodiment, dragging the current data point along the track bar is achieved by a scroll wheel.

摘要： There are terminal devices, also referred to as boxes, either newly installed or put back onto a system after a period of time. The system is configured to offer media services. An original library in each of such boxes is updated with the most demanded titles first or the least amount of data possible so that a box may be in condition sooner to not only fulfill orders for the most demanded titles but also provide needed data to other boxes. Depending on implementation, the updating of the original library in a box may be carried out by receiving data chunks by a gossip protocol from other boxes that collectively have the latest titles or receiving proper release packages from a service provider via a broadcasting or multicasting infrastructure.

摘要： Techniques for transporting data in a distributed environment are disclosed. In a media system in which boxes are configured to supply each other needed data, stabilities of data transportation among the boxes are important. According to one aspect of the techniques, when one or more supplying boxes are identified to supply respective data portions to an ordering box, each communication session between the ordering box and one of the supplying boxes is constantly monitored. If the data is not transported correctly, a backup session by a backup box is activated to replace the session in which the data is not transported correctly. Without affecting the number of available boxes that may be designated to supply data to other ordering boxes, in one embodiment, one box is used to backup multiple boxes.

摘要： Techniques for minimizing blocking artifacts in video images or frames are disclosed. In general, these blocking artifacts are the result of block-based compression standards, such as MPEG-1, MPEG-2, MPEG-4, H.261, H.263, and H.264. According to one aspect of the present invention, a blurring process is configured to replace pixels on the blocking boundaries with randomly selected pixels within respective regions, each of the regions is predefined with respect to a pixel being replaced. In a certain perspective, a blocking boundary is diffused without introducing blurring to other than the blocking artifacts. According to another aspect to the present invention, pixels in an image or frame are sequentially processed by a moving average process that is configured to smooth only those pixels that may cause subjective perception of the blocking artifacts.

摘要： To ensure that media services are only provided to those authorized users or receiving devices, various conditional access mechanisms are provided to secure that media services are only received in those authorized. Different from a prior art conditional access system, an entitlement control message containing a master key can be sent directly to an ordering box. Depending on implementation, a secure session may be established between a server and an ordering box, such that all secured information including a master key may be transported. Further an ordering box does not need to possess a key or keys needed to decrypt an entitlement control message, such key(s) may be transported from time to time in a secure session established between the server and the ordering box.

摘要： Techniques for keeping personalized settings across network are disclosed. According to one aspect of the present invention, personalized settings (e.g., parameters or table) are managed in a primary client device associated with a subscriber. A copy of the copy of personalized settings is maintained in a server. When it is detected that the subscriber is logged on in a different client device (e.g., a box), a copy of the personalized settings is uploaded to the different client device that is configured to respond to the personalized settings. As a result, the subscriber sees the familiar settings on the different client device.

摘要： Techniques for distributing restricted media to consumers are disclosed. According to one aspect of the present invention, personalized settings (e.g., parameters or table) are managed in a primary client device associated with a user. A copy of the personalized settings is maintained in a server. When the primary box is replaced, a copy of the personalized settings is uploaded to a different client device that is configured to respond to the personalized settings. Data pertaining to titles in a personal vault is preloaded. When there is an order for a release that is restricted for distribution over an open network, data pertaining to such a release is also loaded. As a result, the subscriber sees the familiar settings on the different client device and would not miss any release while the primary box is being replaced or repaired.

摘要： Various techniques for a library with a significant number of titles are disclosed. A user may select and order a title whenever desired and play back the title fairly instantly. The library is dynamically updated in accordance with a schedule. According to one aspect of the techniques, whenever an ordered title is played back, a beginning portion of the data pertaining to the title is activated to be played back first. The beginning portion of the data is locally cached while the remaining portion of the data is supplied by other designated devices. To facilitate the management of the remaining portion of data for each of the titles in the library, the titles are partitioned into a number of groups or bands. The amount of the remaining portion of the data to be locally cached for each title is determined by a band the title belongs to. Further, as new titles are added in, the titles in each band are updated by retiring relatively unpopular titles to a lower band.

摘要： Various techniques for providing instantaneous media services are disclosed. Some of the techniques provide an instantaneous media-on-demand system, process and method for the same. Such a system offers a dynamic library with a significant number of titles from which a user may select and offers play back a desired title fairly instantly. To facilitate instant playback, a file pertaining to a title is fragmented into a header and segments. The header is seeded in all boxes in service and none, one or more segments are distributed to the network of boxes. When the title is ordered, the header is instantly played back while the segments, if not locally available, are streamed in respectively from the boxes having the segments to enable continuous playback of the ordered title.
