Abstract: A method of performing a rate-distortion optimization process comprising, for each of a plurality of target image portions to be encoded in each of a plurality of frames, selecting a preferred one of a set of encoding modes by optimizing a function comprising an estimate of distortion for the target image portion and a measure of bit rate required to encode the target image portion, wherein the estimate of distortion is based on source coding distortion and an estimate of a distortion that would be experienced due to possible loss over the channel; encoding the target image portion into the encoded video stream using the selected encoding mode; and transmitting the encoded video stream over the channel. The rate-distortion optimization process for a current one of the frames is performed in dependence on feedback received from the receiving terminal based on an earlier one of the frames.

Abstract: The present invention is directed to a method and system for continuously displaying image pages of digital content which are available over a network. More specifically, the method and system enables a user to view image pages in a continuous manner while a limited number of image pages are being downloaded at a given time. Several image pages which are adjacent to the image page(s) the user is currently viewing may be stored in temporary memory. The image pages in the temporary memory are utilized so that, within the image pages, the user can move the displayed image pages up and down without experiencing any discontinuation. In order to ensure continuous display throughout the entire digital content, the next possible set of image pages is constantly determined and obtained to update the current set of image pages in the temporary memory.

Abstract: Method, device and computer program product for stabilizing a received video signal. A plurality of frames of the video signal is captured using a camera. The video signal is transmitted as an encoded bit stream. Displacement of the camera between successive frames is determined from a motion indication in the bit stream. The determined displacement is used to compensate for motion in the video signal between successive frames caused by the motion of the camera, to thereby stabilize the video signal.

Abstract: An encoder allocates index numbers to portions of a video signal transmitted over a network to a decoder. At least some of the portions are stored in an encoder buffer. Feedback is received from the network at a remote control block, indicating whether the transmitted portions are correctly received. Based on the feedback, the control block determines a subset of the portions stored in the buffer. The control block transmits a message to the encoder, identifying the subset using the index numbers allocated to the portions in the subset. In response, the encoder uses the index numbers to identify and retrieve at least one portion of the subset of portions from the buffer, the retrieved portion is used to encode subsequent portions of the signal.

Abstract: The present invention is directed to a method and system for verifying a user for copying or printing a limited portion of digital content while allowing the user to view the digital content. The digital content may have image portions that are digital images generally scanned from a printed page of the content and text portions that are digital texts including all forms of letters, characters, symbols, etc. An interactive image document displaying image portions of the digital content is provided for secure data access to text portions. A user can request and obtain a limited text portion of the digital content or view the image portions of the digital content via user interactions within the interactive image document. While the text portions can be reproduced, copied, or printed, the image portions can not be re-used or manipulated by the user due to their non-text accessible format.

Abstract: A method of delivering an encoded data stream to a plurality of recipient end-user nodes of a network includes receiving an incoming encoded data stream at a first recipient node from a transmitting node over the network. During ongoing receipt of the incoming encoded data stream at the first recipient node from the transmitting node, the incoming encoded data stream is decoded at the first recipient node to produce a decoded data stream that is output for consumption at the first recipient node. The decoded data stream is used to generate a modified encoded data stream being a modified version of the incoming encoded data stream. Still during ongoing receipt of the incoming encoded data stream at the first recipient node from the transmitting node, the modified encoded data stream is relayed from the first recipient node to one or more second recipient nodes over the network.
