Abstract: An encoder allows generating, starting from a sequence of digital video pictures, a time-scalable encoded bitstream obtained by applying to the pictures, a hierarchical prediction wherein the pictures are organized in Groups Of Pictures (GOPs). The GOPs may include base time layer pictures or Key Pictures for encoding as Inter or Intra, with and without motion-compensated prediction respectively. The GOPs may also include higher time layer pictures adapted to be selectively eliminated to effect time scalability of the encoded scalable bitstream. The encoder may detect scene changes in the sequence of digital video pictures, and, in the presence of a scene change, a first Key Picture after the scene change may be encoded as Intra.

Abstract: An object located within an image foreground relative to image content within a field of view of at least one camera lens is identified, using image processing module, as an image obstruction. Responsive to identifying the image obstruction, points of view of at least one camera lens are determined that provide image content portions of the image content that, in combination, yield a complete image of the image content without the image obstruction located within the image foreground. The image content portions are combined to yield the complete image of the image content without the image obstruction located within the foreground. The combined complete image is stored to a memory.

Abstract: In a moving picture in which data corresponding to one picture is required for display, data corresponding to one picture is divided into line blocks including a predetermined number of pixel lines and captured as block data. A compression rate of each block data is dynamically set according to a capture point in time of each block data. Each block data is compressed at the set compression rate and transmitted to a reception apparatus through a transmission path. On a plurality of block data, a series of processes including the capture and the transmission of each block data is performed in parallel while shifting only a time required for the capture. Block data that is late in start order of the capture, among the data corresponding to one picture, is set to be lower in compression rate than block data that is early in start order of the capture.

Abstract: Profiling and tracking vehicles using cameras is disclosed. Initially, two or more first images from a first camera having a first field of view are received. A first static characteristic of a first vehicle is determined based on at least one of the two or more first images. Next, a desired static characteristic of a vehicle of interest is received. The desired static characteristic of the vehicle of interest is compared with the first static characteristic of the first vehicle. In response to the comparison, it is determined that the desired static characteristic of the vehicle of interest is approximately equal to the first static characteristic of the first vehicle. In response, it is determined that the vehicle of interest is present in the first field of view of the first camera. Finally, it is indicated that the vehicle of interest is present in the first field of view.

Based on the evaluation, the host of the sender encodes and transmits the high quality media stream to at least one selected host associated a viewer.

Abstract: An organic electroluminescence display includes pixels in a matrix that each emits visible light. A data line driver supplies a video signal to each pixel. The video signal includes first and second frames corresponding to first-eye and second-eye image information. A scanning line driver distributes a scanning signal to each pixel for controlling a supply of the video signal. The display includes an emitter in an arrangement position of the pixels in the matrix. The emitter emits infrared light in a same direction as the visible light. The scanning line driver supplies a control signal to the emitter that indicates a switching timing between the first frame and the second frame, and causes the emitter to emit the infrared light based on the control signal for reception by eye glasses for controlling opening and closing of electronic shutters.

Abstract: A video stream is encoded with a prediction mode of which a picture later than an I picture in the display order is predicted from a picture earlier than the I picture in the display order and recorded on a record medium so that the video stream reproduced from the record medium is randomly accessible. When a video stream is encoded, the prediction mode of which a picture later than an I picture in the display order is predicted from a picture earlier than the I picture in the display order is prohibited. In addition, EP_map that correlates reproduction time information of an I picture to a packet number of the I picture is created and recorded on the record medium along with a packetized encoded stream. When the video stream is reproduced, EP_map is searched for a packet number corresponding to a designated reproduction time. Corresponding to the obtained packet number, decoding of an encoded stream reproduced from the record medium is controlled.
