摘要： Techniques are provided for video communication between multiple devices. Each of a plurality of video packets is designated as being part of a required reference frame that is subsequently to be used for a repair process. A stream of video packets that includes the packets for the required reference frame is transmitted from a source device over a communication medium for reception by a plurality of destination devices. A determination is made that at least one of the plurality of destination devices did not receive at least one packet of the required reference frame, and the at least one packet is retransmitted the at least one of the plurality of destination devices. When the retransmitted packet is received at the at least one destination device, it is decoded and stored without using it for generating a picture for display at the time that the at least one packet is received.

摘要： A system and method for providing a plurality of viewing angles and images on a display. An embodiment comprises a display system where a user has the option of determining the number of images to view and the range of viewable angles for each image. A display system is configured to display a maximum number of images at different viewing angles by interlacing a plurality of images so that each viewing angle shows a selected image. The display system provides a method by which an operator can increase the viewing area of an image by interlacing the same image to more than one viewing angle.

摘要： An apparatus, software encoded in tangible media, and a method at an encoder. The method includes sending compressed video data including a reference frame message to create a long term reference frame to a plurality of decoders at one or more destination points, receiving feedback from the decoders indicative of whether or not the decoders successfully received the reference frame message, and in the case that the received feedback is such that at least one of the decoders did not successfully receive the reference frame message or does not have the indicated recent frame, repeating sending a reference frame message to create the long term reference frame. Using the method can replaces I-frame error recovery with long term reference frames, even in the case where the reference frame management messages are lost to at least one decoder.

摘要： An apparatus, a method, and a computer-readable medium having instructions encoded thereon that when executed cause a method to be carried out. The method includes dividing at least a portion of a picture of a video stream into parts of blocks, and processing the parts in parallel by a plurality of interconnected processors. The processing of a respective part by its respective processor includes determining block-level temporal difference features. Each processor also performs coding functions on its respective part of the picture. The method also includes block-level processing using the block-level temporal difference features to determine which blocks in the picture are likely to be that of a face, the block-level processing being at the granularity of at least a block. In one version, the processing in each processor includes edge detection and color segmentation to determine block-level edge features including block-level color-segmented edge features that are then used in the block level processing.

摘要： Certain ones of a total array of ultrasonic transducers constitute a small aperture and are so energized as to project acoustic energy onto predetermined parts of a scene. Reflections of the transmitted signals are received by certain ones of the array, are converted to electrical signals and are appropriately delayed to enable additive combination of the amplitude of the received signals emanating from the same points in the scene ("targets"). The phase (or time delay) as well as the amplitude information of the reflective signals are stored. Next, the same transmitting elements ("subarray") project acoustic energy upon the remaining parts of the scene in sequence and the reflected signals are similarly processed and stored. This continues until all the parts of the predetermined scene have been interrogated by insonification from that subarray and the reflected signals have been similarly processed. Then, at least one more set of transducers of the total array, which also constitute a small aperture, are caused to scan the same parts of the image in the same sequence thereby producing the same types of reflected signals which are processed similarly, and whose amplitude and phase information is similarly stored. The plurality of the stored signals from each subarray, which may be termed "complex image" signals, are then vectorially added and further processed to derive a video signal which is used to produce a final display image.

摘要： An apparatus is provided in one example and includes a camera configured to receive image data associated with an end user involved in a video session. The apparatus also includes a display and an optics element configured to interface with the camera. The optics element reflects the image data associated with the end user positioned in front of the display. A retracting mechanism is also provided and is configured to retract the optics element in a direction such that the camera moves to an inactive state and the optics element is removed from a view of the display from the perspective of the end user. An effective optical distance from the camera to the end user is increased by manipulating a position of the optics element. In more detailed embodiments, the camera can be configured above the display such that its lens points downward toward the optics element.
