摘要： In a method for encoding and an encoder statistical information is generated and said statistical information (LSB=F(MSB) about the reconstruction values to be used during reconstruction (sometimes called "inverse quantization") is added to the encoded data signal. The encoded data signal comprises data information providing information on the relation between parts of the original input data removed during quantization and the quantized data. The decoder and decoding method use the information data during reconstruction. This enables reconstruction values to be used during reconstruction that can adapt to the input data statistics thereby improving data reconstruction and reducing the quantization error. The reconstruction at the decoder is guided by information data which is gathered at the encoder, this information data being derived from determining statistical information on the removed parts of the input data in relation to the after quantization remaining quantized data.

摘要： A coding system (1) comprises an encoder device (2) and a decoder device (3) which both have a memory unit (23; 33) arranged in a loop for generating a prediction signal (y; g). The memory units apply lossy compression to reduce the memory requirements. In order to prevent drift due to dissimilar data reduction, the lossy compression in the encoder device (2) is substantially identical to the lossy compression in the decoder device (3). For example, both compressions may involve identical algorithms, compression factors and/or compression parameters. Information indicative of the lossy compression and / or decompression is added by the encoded.

摘要： A hither before unknown cause of image artefacts has been identified. Encoders such as MPEG encoders may use two picture structures: Field pictures and frame pictures. For a frame picture both frame and field-based DCT (and other types) of coding may be used. The decision whether to use frame or field based coding is not always made correctly. In the decoded image this leads to an image artefact visible as stripped blocks. The invention reduces, in one aspect of the invention, these artefacts by analyzing the block content on the presence of such artefacts and if the analysis proof the existence of such artefacts applying a vertical low pass filter to the data in the block. In another aspect of the invention encoding parameters are checked for combination of encoding parameters for which the artefact may occur and such blocks are indicated. The invention may be embodied in a method as well as in a device such as a receiver, encoder, decoder, display device etc.

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 fullquality 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： The invention relates to a cost-effective method of modifying a non-scalable coded video signal for generating a scalable coded video signal comprising a base layer and a set of enhancement layers. The base layer results from a bit shift performed by a shift matrix applied on coefficients, and an extraction of a reduced number of least significant bit planes. The enhancement layers result from the bit-plane coding of the least significant bit planes. Contrary to a requantization method that would identically truncate all coefficients in a block and would cause visual artifacts, the shift matrix allows a progressive attenuation of the coefficients. The base layer is then composed of dampened coefficients. The invention also relates to a cost-effective method of modifying said scalable coded video signal for generating a non-scalable coded video signal.

摘要： Both the frequency weighting and region of interest enhancement in MEPG4-FGS are implemented by shifting in a number of zeros in the least significant bits of selected discrete cosine transform (DCT) coefficients, by application of a weighting matrix. This effectively shifts these coefficients up a few bit planes, thereby causing their bits to appear earlier in the enhancement layer bit stream than would otherwise be the case. Thus they are given priority over coefficients that have not been shifted or have been shifted by a smaller amount in the event that the bit stream is cut. To propose herein to modify the enhancement layer bits stream of the MEPG4-FGS standard so that zeros that are shifted in are no longer encoded, thereby increasing the compression efficiency when either no or only a small number of bits is cut off from the enhancement layer.
摘要翻译：通过应用加权矩阵，在选定的离散余弦变换（DCT）系数的最低有效位中通过移位零个数来实现MEPG4-FGS中的频率加权和兴趣区域增强。这有效地将这些系数移动到几个位平面，从而使得它们的比特在增强层比特流中比以前更为出现。因此，在比特流被切断的情况下，它们被优先于没有被移位或已被移位较小量的系数。为了在本文中提出来修改MEPG4-FGS标准的增强层比特流，使得被移入的零不再被编码，从而当从增强层中切出不少或只有少量比特时提高压缩效率。
