Abstract: A device can provide a first function and a second function. The first function can have a higher priority for power than the second function. An input element can receive an indication of a remaining capacity of a power source for the device. A comparison element can compare the indication of the remaining capacity of the power source to a power threshold associated with the second function. A control element can initiate a power control action with respect to the second function if the indication of the remaining capacity of the power source is below the power threshold.

Abstract: According to some embodiments, context information associated with a processing system may be determined. It may then be automatically arranged for a power state associated with the processing system to transition from a first power state to a second power state based on the context information.

Abstract: Method and apparatus to manage power for a communication device having multiple radios are described.

Abstract: An instant-on PC is described which can be revived from a sleep state in a matter of seconds. This is carried out by keeping certain power-managed devices in a quickly-revivable state, e.g., the memory and certain elements on the motherboard chipset. Certain PCI devices are also enabled in a quick wake-up state so that they can wake up on a specified stimulus. The power consumption of each of these devices is obtained and it is determined if that power consumption exceeds the power capability of the auxiliary power supply. If not, the more aggressive sleep state is enabled. If so, however, the system takes action to either enter a less aggressive sleep state or to selectively de-enable certain ones of the devices that are in the keep-awake state. Preferably the choice of which to do is made by the user.

Abstract: A method, apparatus, and storage medium for management at least two audio, video, or data (AVD) streams, wherein each AVD stream may comprise a plurality of stream segments. According to a preferred embodiment, the at least two AVD streams are stored in a file. A stream segment directory (SSD) table is stored, having an SSD entry for each stream segment in the file, wherein the SSD entry corresponding to each corresponding stream segment comprises a plurality of fields for characterizing the corresponding stream segment.

Abstract: A method, apparatus, and storage medium for event tagging of at least one audio, video, or data (AVD) stream, each AVD stream comprising a plurality of AVD stream chunks. According to a preferred embodiment, the at least one AVD stream is stored. An event tag is stored in response to a signal indicating the beginning of an event, the event tag having an event stream information data (ESID) structure comprising an ESID entry for each AVD stream of the at least one AVD stream, each ESID entry comprising an offset for locating a corresponding AVD stream chunk of each active AVD stream of the at least one AVD stream.

Abstract: A method, apparatus, and storage medium for temporal indexing of at least two audio, video, and data (AVD) streams, each AVD stream comprising a plurality of AVD stream chunks. A stream information data stream (SIDS) having a plurality of SIDS chunks is stored, each SIDS chunk corresponding to a corresponding AVD stream chunk for each of the at least two AVD streams. A temporal index stream (TIS) having a plurality of TIS chunks is also stored, each TIS chunk corresponding to a corresponding SIDS chunk. Each TIS chunk comprises a time stamp for indicating the current time and an offset for locating the corresponding SIDS chunk. Each SIDS chunk comprises an SIDS chunk entry for each of the at least two AVD streams that is currently active, each SIDS chunk entry comprising an offset for locating the corresponding AVD stream chunk of each active AVD stream of the at least two AVD streams.
