We have decided to post on interesting Microsoft patents regularly from today. When there are sites like patentlyapple that reports on Apple’s patents, we thought of reporting patents awarded from Microsoft. So, this is the first post.
Synchronizing media streams across multiple devices:
Aspects of the present invention are directed at establishing a multimedia network session in which the transmission of media streams is synchronized. In one embodiment, a method is provided for synchronizing incoming audio and video streams. The method includes establishing a communication channel between a first computing device that is receiving an incoming audio stream with the second computing device that is receiving an incoming video stream. Once the communication channel is established, the current network conditions that describe attributes of the incoming audio stream are obtained by the first computing device. Then, the delay in the incoming audio stream is calculated. When the delay is known, the method causes the incoming video stream to be delayed to match the delay in the incoming audio stream.
Touchless and touch optimized processing of retail and other commerce transactions :
A computer implemented method for reducing input performed in a commerce based application is provided. The method includes receiving a sequence of input values from an input device and associating the sequence of input values with an object in the application based on the sequence. A context of the application is determined. One or more tasks in the application are automatically performed based on the object, the context and the sequence of input values.
Controlled anticipation in creating a shadow copy:
Controlling data retention of a collection of data in a data store. An instruction is received to store a shadow collection of data to the data store.
The data store has a previous version of the shadow collection of data. An available amount of data storage space on the data store is identified. An amount of data storage space needed is estimated for storing the shadow collection of data to the data store based on the received instruction. It is determined whether the identified available amount of data storage space is sufficient for storing the estimated amount of data storage space. The shadow collection of data is stored to the data store when said determine indicates that the identified available amount of data storage space is sufficient and the previous version is permitted to be deleted or to be overwritten.
