508 results about "Picture-in-picture" patented technology

Picture-in-picture (PiP) is a feature of some television receivers and similar devices. One program (channel) is displayed on the full TV screen at the same time as one or more other programs are displayed in inset windows. Sound is usually from the main program only.

Picture-in-picture and multiple video streams using slice-based encoding

Methods for slice-based encoding of program guides and user interfaces. The program guides include multiple video streams for picture-in-picture and other applications. A method for encoding the program guide includes encoding a first set of slices for each of a plurality of graphics pages; and encoding a second set of slices for each of a plurality of video streams. The user interfaces are multi-functional and may be used for electronic commerce and other applications. A method of generating the user interface includes encoding a set of slices for each of a plurality of objects, each object being characterized by an identity, at least one attribute, and at least one operation. In one embodiment of this method, the plurality of objects include an electronic commerce object, where the electronic commerce object is attributed with a first hyper text markup language (HTML) page. A head-end centric system and apparatus for encoding and delivery of realtime content, including: a non-realtime content source for providing non-realtime content; a non-realtime encoder for encoding the non-realtime content into encoded non-realtime content; a realtime encoder source for providing realtime video and audio content; a realtime encoder for encoding the realtime video and audio content into encoded realtime video an audio; a remultiplexor for repacketizing the encoded non-realtime content and the encoded realtime video and audio into transport packets; and a re-timestamp unit coupled to the remultiplexor for providing timestamps to be applied to the transport packets in order to synchronize the realtime and non-realtime content therein.

Method for coding two-directional predictive video object planes and decoding device

Temporal and spatial scaling of video images including video object planes (VOPs) (117, 118, 119, 405, 415, 420, 430, 520, 522, 524, 526, 532, 542, 705, 730, 750, 760, 780, 790, 805, 815, 820, 830, 850, 860, 880, 890) in an input digital video sequence is provided. Coding efficiency is improved by adaptively compressing scaled field mode video. Upsampled VOPs (450, 490, 522, 542, 750, 790) in the enhancement layer are reordered to provide a greater correlation with the input video sequence based on a linear criteria. The resulting residue is coded using a spatial transformation such as the DCT. A motion compensation scheme is used for coding enhancement layer VOPs (450, 460, 480, 490, 522, 524, 526, 542, 750, 760, 780, 790, 850, 860, 880, 890) by scaling motion vectors which have already been determined for the base layer VOPs (405, 415, 420, 430, 520, 532, 705, 730, 805, 815, 820, 830). A reduced search area whose center is defined by the scaled motion vectors is provided. The motion compensation scheme is suitable for use with scaled frame mode or field mode video. Various processor configurations achieve particular scaleable coding results. Applications of scaleable coding include stereoscopic video, picture-in-picture, preview access channels, and ATM communications.

Method, system and mobile terminal for realizing one-handed mobile terminal operation

The invention is applicable to the field of mobile terminals, and provides a method, a system and a mobile terminal for realizing one-handed mobile terminal operation. The method comprises the following steps of: receiving a command for starting a one-handed operation mode; according to the command, zooming out a screen to a preset size; and displaying a reduced screen thumbnail on an original screen in a picture in picture mode. Through starting the one-handed operation mode, the screen thumbnail which is smaller than the original screen is displayed on the original screen of the mobile terminal in the picture in picture mode. The operation on the thumbnail is mapped to the operation on a large screen, so that the operation on the thumbnail equals to the operation on the large screen, and moreover, the operation on the screen except for the thumbnail can also be responded. The operation of the large screen is not influenced on the basis of controlling the big screen through the thumbnail; and thus, a one-handed operation function of a large-screen mobile phone is realized, good experiences are brought to users, one hands of the users can also be released to do other things, so that conveniences are brought to the users. The one-handed operation mode cannot influence the displaying effect of the large-screen mobile phone, and cool experiences are realized in the way that small-scope operation controls large-scope display.
