摘要： A computer-implemented method comprises obtaining an intermediate computer code object including a set of instructions corresponding to a task to be performed. The intermediate computer code object—being machine independent—further includes for each of the at least one set of instructions one or more metadata descriptors representative of at least a complexity measure of the task to be performed. The method also comprises executing the intermediate computer code object on a computing platform comprising at least two different execution units having a different memory with a different memory location. This executing comprises selecting for each of the at least one set of instructions a target execution unit from the plurality of execution units. This selecting takes the one or more metadata descriptors and a decision rule into account, wherein the decision rule relates the plurality of complexity measures to a performance characteristic of the plurality of execution units.

摘要： To alleviate constrained nodes (102a-e) from implementing a functionality, a functionality is emulated by an intermediary node (110) for the constrained nodes (102a-e). The intermediary node is configured to intercept requests and process the requests on behalf of the node to fulfill a functionality. The functionality is typically not supported by the constrained node (102a-e). The support for the functionality is added to resource discovery responses, resource announcement messages, and/or resource registration messages to indicate to a client or a resource directory that the emulated functionality is supported by the node.

摘要： A method for enabling restoration of an operational state on a server node is disclosed. The method includes intercepting, by a state directory, traffic between the server node and a client communicably connected to the server node over a network to derive the operational state. At least a part of the traffic between the server node and the client leads to establishment of the operational state on the server node. The method further includes storing the operational state in the state directory, detecting, by the state directory, that the server node has lost the operational state, and providing, by the state directory, the operational state to the server node after detecting that the server node has lost the operational state.

摘要： The present invention is related to a hash-based distributed video coding architecture. At the encoder, the input video sequence is organized in Groups of Pictures (GOPs) and is decomposed into key frames, i.e., the first frame in each GOP, and WZ frames. The key frames are encoded using H264/AVC Intra frame coding. The Wyner-Ziv (WZ) frames are encoded in two parts, a hash layer and a WZ layer. To construct the hash information, the WZ frames are quantized and each quantized frame is then decorrelated using spatio-temporal prediction and entropy coded, and then multiplexed with the encoded key frames. At the decoder, the intra bit stream is H264/AVC decoded and the intra frames are stored in a reference frame buffer. The hash is decoded by inverting the tasks applied at the encoder, i.e. entropy decoding and inverse spatio-temporal prediction, and the obtained bit planes are stored. Next, Overlapped Block Motion Estimation and Probalistic Compensation (OBMEPC) is used to estimate the missing bit planes in the side - information. The decoder utilizes the hash information and the side information frame created by OBMEPC to perform online estimation of the correlation channel, and produces soft estimates used to decode the WZ bit planes.

摘要： A method for binding a first and second devices is disclosed. The method is implemented using the architectural principles of REST, which allows a binding initiator to directly contact the first device and instruct the device of actions to be taken. Specifically, the binding initiator may contact the first device by providing a first REST request to the device, the request specifying that the first device is to monitor a state of a particular REST resource identified by the request and is to trigger the second device to perform a specified action when the state of that REST resource satisfies a particular condition. Using REST further allows the first device to directly contact the second device and instruct the second device to perform the specified action. Since the first device is now able to directly contact the second device, these two devices may be considered to be bound.
