Abstract: Innovations in adaptive encoding of screen content based on motion type are described. For example, a video encoder system receives a current picture of a video sequence. The video encoder system determines a current motion type for the video sequence and, based at least in part on the current motion type, sets one or more encoding parameters. Then, the video encoder system encodes the current picture according to the encoding parameter(s). The innovations can be used in real-time encoding scenarios when encoding screen content for a screen sharing application, desktop conferencing application, or other application. In some cases, the innovations allow a video encoder system to adapt compression to different characteristics of screen content at different times within the same video sequence.

Abstract: A method of event scheduling includes scheduling an event having an event time and an event location; determining a position of the user prior to the event; calculating a travel time required before the event according to the event location and the position of the user prior to the event; and reminding the user of the event according to the travel time before the event time.

Abstract: A route planning triggering method is implemented in a route planning device and includes the following steps. An image is captured through an image capture device coupled to the route planning device. The position information of a geographical location is automatically generated from the captured image for planning a route to the location.

Abstract: A key-frame processor for computer system is provided to couple with the streaming server of the computer system to transmit a series of continuous computer image frames to a plurality of user sites. The key-frame processor for computer system comprises a key-frame reconstruction module and a key-frame selective streaming module. The key-frame reconstruction module is coupled with an instructor computer system to obtain image data transmitted by the instructor computer system to the streaming server, which image data represent image being displayed at the instructor computer. The key-frame reconstruction module reconstructs the obtained image data into displaying data representing the whole image as displayed, maintains data of the whole image being currently displayed at the instructor computer from time to time and stores the whole image data at the streaming server regularly.

Abstract: A real-time screen recording system is disclosed. Under the design of the real-time screen recording system of this invention, the Event Inspector records updated regions of the screen when a windows update event is generated, the Periodical Extractor records the screen updates periodically. This mechanism ensures that all updates will be recorded. The Event Filter inspects the update events to identify events relating to updates of screen to ensure correct recording of the updated regions. The Sporadic Controller adjusts the working frequency of the Periodical Extractor, so that the Periodical Extractor operates in an efficient manner. The Update Region Filter filters out unnecessary updated regions to avoid heavy workload of the computer system. As a result, an efficient and correct screen recording system may be achieved.
