Abstract: When distributing a set 101 of frames 102 each with encoded data 103 from a transmitter 104 to a receiver 105, a dependent frame 108 requires an independent frame 107 for decoding, and the transmitting 111 of the frames 102 from a buffer 110 at the transmitter 104 is reordered such that the dependent frame 108 is sent after the independent frame 107. In particular, a transmission policy wherein buffering 109 a further frame 125 takes into account both: if the further frame 125 requires zero, one or two frames 102 of the set 101 for decoding, and the current frames 102 buffered at the first and the second position 123 of the transmit buffer 110.

Abstract: A method of determining a best-case response time of a first periodic task, the method comprising a first step based upon Rate Monotonic Analysis of determining the priorities of the tasks that have to be scheduled on a system. In order to determine whether the set of tasks can be scheduled on the system, the best-vase response time in addition to the worst-case response time is determined per task. This best-case response time is substantially equal to the difference between the start of a task with a lower priority and the completion of this low priority task, the start being right after the release of the low priority task and the completion coinciding with the simultaneous release all higher priority tasks.

Abstract: In consumer devices, like digital television sets or set-top boxes, there can be a problem with a sudden load increase caused by for example a scene change and user focus. During such a load increase, the quality of service of the application having the user focus will decrease until the device detects the load increase. The device can reallocate resources to the application having the user focus after which the quality of service will increase again towards its previous level. However, the user may have noticed the quality decrease. In order to prevent this noticeable decrease of quality in overload situations, a method and a system are provided that guarantees a worst-case budget to the application having user focus and conditionally guarantees a budget surplus to an application not having the user focus. The latter application can then use that budget surplus to operate at a higher quality of service level.
