    摘要: A method of processing an input signal (SG0) is described. The method involves receiving the input signal (SG0). Moreover, the method also involves processing the input signal (SG0) into a base stream (SG1) and one or more enhanced streams (SG2, SG3) wherein the base stream (SG1) includes basic signal information and the one more enhanced streams (SG2, SG3) include enhancement signal information complementary to the basic signal information.

    摘要: A method and apparatus for providing elastic storage of layered video data stored in a storage apparatus are disclosed. The stored enhancement layer video data is read out of the storage apparatus. The enhancement layer video data is then at least partially decoded or ultimately completely deleted. The decoded enhancement layer video data is attenuated in a linear or non-linear manner. The attenuated enhancement layer video data is then encoded. The encoded attenuated video data is stored back in the storage apparatus.

    摘要: Video signals are converted into a stream of digital numbers arranged in a sequence of digitized video frames (14), neighboring frames being separated by a synchronization signal (16). A sensing circuitry (30) monitors the synchronization signals and detects absent synchronization signals. A clock generator (32) generates a replacement synchronization signal based on the monitored synchronization signals. The replacement signals can replace all of the synchronization signals, e.g., with an average sync frequency, or replace only missing or corrupted synchronization signals. The replacement synchronization signals are generated and inserted either at a fixed rate or at an actual clock rate. In a preferred embodiment, a learning circuitry (42) collects and averages the clock rate of the synchronization signals for a preselected duration. The value is supplied to the clock generator to output the replacement synchronization signals at the actual clock rate. A compression circuit (20) is clocked by the output of the clock generator.

    摘要: During image compression alternative video compression technique are selected under control of an extent to which a computational resource is detected to be available for compression. A less or more resource intensive compression technique is used when more of the resource is available respecrtively. At least part of a frame from a sequence of frames from the video information is encoded alternatively using a first process by means of change information relative to a neighboring frame or using a second process independent from any neighboring frame in said sequence, dependent on the extent to which the resource is available it is selected to encode.

    摘要: The device and method according to the invention prevent that the consistency of image quality is negatively affected when transmission rate fluctuations occur on a communication channel. The invention relies on the perception that the transition from a full quality video signal to a basic-quality video signal, respectively from a basic-quality video signal to a full-quality video signal, should be a gradual transition instead of a sudden transition. The blending process can be implemented by circuitry which applies a blending factor on the decoded video signals of the base layer and the enhancement layer(s), before these decoded video signals are merged to form a single output video signal. Due to the delay time of the decoding process there will be a natural delay between the moment a transition occurs in the received video data and the moment that a transition occurs in the full-quality video signal. During that time interval the blending factor may be changed gradually, so that the visibility of the transition is reduced. It may be preferable to provide for an extra delay in addition to this natural delay. This enables the device to further smooth away the effect of the quality transition in the received video data.

    摘要: An apparatus is disclosed for performing spatial scalable compression of video information captured in a plurality of frames including an encoder for encoding and outputting the captured video frames into a compressed data stream, comprising a base layer comprising an encoded bitstream having a relatively low resolution, a high resolution enhancement layer comprising a residual signal having a relatively high resolution, and wherein a dead zone operation unit attenuates the residual signal, the residual signal being the difference between the original frames and the upscaled frames from the base layer. As a result, the number of bits needed for the compressed data stream is reduced for a given observed video quality.
