Abstract: Mobile computing device power consumption can be reduced by using expiration window timers, state-based timers and/or the coordination of keep-alive timers. Upon detecting a trigger event causing a mobile computing device to transition from a low-power state to an active state, the device can determine whether the trigger event occurs within the expiration window of a timer, and execute tasks associated with the trigger event and the timer. Tasks associated with state-based timers can be executed if the mobile computing device or a component thereof is in (or, alternatively, not in) a specified state. A mobile computing device can execute tasks associated with multiple keep-alive timers used for maintaining communication links between the device and cloud-based service providers in a single active state. A cloud-based keep-alive service can maintain mobile computing device-service provider communication links by sending one keep-alive communication to a mobile computing device in place of multiple communications.

Abstract: Various embodiments enable a device to create a pool of at least one empty application. An empty application can be configured to contain resources that are common across one or more other applications and initialize the resources for the one or more other applications effective to reduce startup time of the other applications. In one or more embodiments, an empty application can further be populated with the one or more other applications effective to cause the one or more other applications to execute. Alternately or additionally, a device can be monitored for an idle state, and, upon determining the device is in the idle state, at least one empty application can be created.

Abstract: Architecture for enhancing the compression (e.g., luma, chroma) of a video signal and improving the perceptual quality of the video compression schemes. The architecture operates to reshape the normal multimodal energy distribution of the input video signal to a new energy distribution. In the context of luma, the algorithm maps the black and white (or contrast) information of a picture to a new energy distribution. For example, the contrast can be enhanced in the middle range of the luma spectrum, thereby improving the contrast between a light foreground object and a dark background. At the same time, the algorithm reduces the bit-rate requirements at a particular quantization step size. The algorithm can be utilized also in post-processing to improve the quality of decoded video.

Abstract: An indexed file layout, comprising index information, is defined for segmented streaming of multimedia content. The index information can comprise program description information and streaming segment index information. In addition, the layout can comprise files containing streaming segments of the program, where the streaming segments are each encoded at one or more bitrates independently of other streaming segments of the program. The layout supports client switching between different bitrates at segment boundaries. Optimized client-side rate control of streaming content can be provided by defining a plurality of states, selecting available paths based on constraint conditions, and selecting a best path through the states (e.g., based on a distortion measure). In one client-side rate control solution states correspond to a specific bitrate of a specific streaming segment, and in another client-side rate control solution states correspond to a measure of client buffer fullness.

Abstract: A method of encoding an input video stream comprising a video component and an audio component is disclosed. The input video stream is split into a plurality of segments, each comprising a plurality of frames. Each of the segments is encoded as a low bit rate layer, a high bit rate layer, and one or more intermediate bit rate layers. The bit rate of the low bit rate layer is selected such that a network streaming the segment will always be able to stream the segment encoded as the low bit rate layer. The bit rate of the high bit rate layer is selected such that the segment is able to be decoded and played back at or above a quality threshold. The bit rates of the intermediate bit rate layers are produced by applying a bit rate factor to another bit rate.

Abstract: Architecture that employs texture sensitive temporal filtering to reuse motion estimation information in a realtime encoder. The temporal filter is applied for classified static areas. The architecture reuses the motion estimation results on motion vectors, cost estimates (e.g., sum of absolute difference (SAD)), and edge awareness texture information to apply the temporal filter on the current picture. Filtering can be applied at the pixel level, block level or macroblock level.

Abstract: A system architecture including a co-processor and a memory switch resource is disclosed. The memory switch includes multiple memory blocks and switch circuitry for selectably coupling processing units of the co-processor, and also a bus slave circuit coupled to a system bus of the system, to selected ones of the memory blocks. The memory switch may be constructed as an array of multiplexers, controlled by control logic of the memory switch in response to the contents of a control register. The various processing units of the co-processor are each able to directly access one of the memory blocks, as controlled by the switch circuitry. Following processing of a block of data by one of the processing units, the memory switch associates the memory blocks with other functional units, thus moving data from one functional unit to another without requiring reading and rewriting of the data.
