Abstract: A first representation of a video stream is received that includes video frames, the representation expressing the video frames at a relatively high pixel resolution. At least one of the video frames is detected to include a region of interest. A second representation of the video stream that expresses the video frames at a relatively low pixel resolution is provided to a video playing device. Included with the second representation is additional information that represents at least a portion of the region of interest at a resolution level that is higher than the relatively low pixel resolution.

Abstract: The present invention provides a way to allow the user to restrict message sets per folder. The invention allows a mail client to offload the burden of automatically constraining the mail content seen at the mobile device. The constraints are fully configurable and manageable by the client at a per mailbox level. There are numerous advantages to the invention including that of a less cluttered mail box and the constraining criteria is user selectable and dynamically configurable.

Abstract: The present invention provides that while a mobile device is connected in an IDLE session on an IMAP mail server the mail client will be able to provide definite acknowledgements to the server as to whether it has received a particular response. If the client is disconnected involuntarily and upon reconnection it will be able to receive any responses that it may have missed during its disconnection and any response it had not acknowledged while connected. This will allow the client to thus avoid doing a deep synchronization after each reconnect. The present invention performs two main functions in order to avoid having the client perform deep synchronization. One, it clearly defines the set of information sent to the client during a reconnection, and two, it defines the behaviour that both the server and the client have during an involuntary loss of connection and the subsequent reconnection.
