摘要： In accordance with one embodiment of the invention, a broadcast server system computes a feasible stretch value for use in scheduling job requests. A stretch value provides an indication of the delay experienced by each job request to complete, when the broadcast server processes many jobs concurrently. A processing time is calculated for each job request based on, the size of the job request and the bandwidth of the server downlink. Thereafter, a stretch value is proposed. The server system computes a deadline for each job to be the arrival time of the job request plus the product of the processing time and the proposed stretch value. Thereafter, each job request is scheduled, based on an “earliest deadline first” arrangement, wherein the job request that has the earliest deadline is scheduled first, the job request having the next earliest deadline is scheduled second, etc. The proposed stretch value is deemed feasible if each pending job request can be completed prior to its deadline. If the proposed stretch value is deemed not feasible, it is adjusted iteratively until a feasible stretch value is found. The feasible stretch value is then utilized to schedule the job requests to be broadcast by the system. When the broadcast of a job request is completed, all job requests for the same data item, which arrived prior to the start of the broadcast, are eliminated from the pending job requests.
摘要翻译：根据本发明的一个实施例，广播服务器系统计算用于调度作业请求的可行拉伸值。当广播服务器同时处理许多作业时，延伸值提供每个作业请求完成所经历的延迟的指示。基于作业请求的大小和服务器下行链路的带宽，为每个作业请求计算处理时间。此后，提出了拉伸值。服务器系统将每个作业的期限计算为作业请求的到达时间加上处理时间和所提出的拉伸值的乘积。此后，基于“最早期限”排列来安排每个作业请求，其中首先调度具有最早期限的作业请求，具有下一个最后期限的作业请求被调度为第二等等。所提出的拉伸值是如果每个待处理的工作请求可以在其截止日期之前完成，则认为可行。如果提出的拉伸值被认为不可行，则迭代地进行调整，直到找到可行的拉伸值。然后使用可行的拉伸值来调度由系统广播的作业请求。当完成作业请求的广播时，在广播开始之前到达的相同数据项的所有作业请求从待处理的作业请求中消除。

摘要： The present invention relates to a method of playing a set of multimedia applications (A), each multimedia application including a list of tasks (TTD). The method includes the steps of creating a common scheduler (SCH) at a start time, in order to provide a target time, registering the tasks into the scheduler, and controlling the execution of the tasks as a function of the target time. The method also includes a step of giving a priority level to the task and the scheduler is adapted to control the execution of the tasks as a function of the target time and the priority level. The method further includes a step of computing a local time for a task from the target time provided by the scheduler and timing information associated with said task. With such a mechanism, each task has its own time reference, thus ensuring a correct operation of the overall application, while a global notion of schedule is maintained.

摘要： An electronic image distribution apparatus for distributing panoramic images is disclosed. The central feature of the system is a panoramic image server coupled to a source of panoramic image information. The source of panoramic image frames may be a panoramic image storage device or a panoramic camera system. The panoramic image server converts the panoramic image frames into a format that is more conducive for electronic transmission. Specifically, the panoramic image server extracts a subset of each panoramic image frame and compresses that subset of the panoramic image. The panoramic image server may also geometrically transform the subset of the panoramic image frame. The compressed subset of a panoramic image frame is transmitted across a transmission medium to a client system. The client system decompresses the subset of panoramic image frame and displays the subset of the panoramic image frame. To conserve bandwidth, the panoramic image server compresses a large portion of the panoramic image frame and leaves a smaller portion of the panoramic image frame. The smaller portion of the panoramic image frame is later expanded by the client system.

摘要： A system and method for the simultaneous transmission and rendition of multiple encoded digital video signal streams in an interactive television application are disclosed. Simultaneous transmission and rendition of multiple encoded digital video signal streams in an interactive television application generally comprises modifying at least one of the multiple encoded video streams broadcast from a broadcast center for repositioning the at least one of the multiple encoded video stream for display, interleaving the modified multiple encoded video streams comprising the at least one modified encoded video stream into a single composite interleaved video stream, and outputting the single composite video stream. The method may further comprise receiving the multiple encoded video streams from a broadcast center. Each of the multiple encoded video streams is preferably encoded using MPEG-1 or MPEG-2 compression technology.

摘要： A set-top electronics and network interface unit arrangement is connected to an internal digital network interconnecting devices in the home. The digital network operates on a single, nomodulated, baseband channel. Entertainment services are introduced into the network through network interface units that are coupled to an external network and to the internal network. The network interface units perform the necessary interfacing between the external and internal networks, and make the entertainment services available to all terminals connected to the internal network. Set-top electronics that are separate from the network interface units connect to the internal network and convert the information in the digital data stream for display, by a television, for example.

摘要： A communication system (100) includes a tap (120) that has an input port (202) for receiving a signal and output ports (225) coupled to the input port (202) for providing the signal to subscriber equipment (125). Each of the output ports (225) has a programmed status comprising either an enabled status or a disabled status. After the statuses have been programmed and the output ports (225) have been set, a controller (210) coupled to the output ports (225) periodically restores the programmed status of the output ports (225) after programmed period of time, thereby automatically resetting inadvertent status changes.
