摘要： In a method for coding and decoding indicator data (d(x, y), S)are compared to a criterion (T). If the indicator data meet the criterion, an absolute value (Hival/Loval) is inserted instead of a predicted value based on differential coding. This amounts to a bypass of the differential coding loop, which reduces or eliminates oscillatory behavior in such loop, thereby reducing smearing of text parts of a compound image. The absolute values are preferably dynamically determined on the basis of previous predicted values.
摘要翻译：在将指示符数据（d（x，y），S）进行编码和解码的方法与标准（T）进行比较。如果指示符数据满足标准，则插入绝对值（Hival / Loval），而不是基于差分编码的预测值。这相当于差分编码环路的旁路，这减少或消除了这种环路中的振荡行为，从而减少了复合图像的文本部分的拖尾。绝对值优选基于先前的预测值动态地确定。

摘要： Compression of digital ink is achieved by calculating second (Fig. 5) order differences between consecutive elements in the digital ink (80, 82) and applying the differences to a Huffman encoder (30) to produce a compressed bitstream (84). For digital ink that is not highly correlated, compression may be achieved by representing segments of the digital ink by mathematical shapes (92) such as a Bezier curve or orthogonal elements and transmitting the shape instead of the digital ink (94).
摘要翻译：数字墨水的压缩是通过计算数字墨水（80,82）中的连续元件之间的第二（图5）阶数差，并将差值应用于霍夫曼编码器（30）以产生压缩比特流（84）来实现的。对于不是高度相关的数字墨水，可以通过用诸如贝塞尔曲线或正交元素的数学形状（92）代表数字墨水的段来实现压缩，并且传送形状而不是数字墨水（94）。

摘要： A system and method of adding hyperlinked information to a television broadcast. The broadcast material is analyzed and one or more regions within a frame are identified. Additional information can be associated with a region, and can be transmitted in encoded form, using timing information to identify the frame with which the information is associated. The system comprising a video source and an encoder that produces a transport stream in communication with the video source, an annotation source, a data packet stream generator that produces encoded annotation data packets in communication with the annotation source and the encoder, and a multiplexer system in communication with the encoder and the data packet stream generator. The encoder provides timestamp information to the data packet stream generator and the data packet stream generator synchronizes annotation data from the annotation source with a video signal from the video source in response to the timestamp information. The multiplexer generates a digital broadcast signal that includes an augmented transport stream from the transport stream and the encoded data packets. A receiver displays the annotation information associated with the video signal in response to a viewer request on a frame by frame basis. A viewer can respond interactively to the material, including performing commercial transactions, by using a backchannel that is provided for interactive communication.

摘要： A method and apparatus for compressing facsimile documents based on arithmetic coding. A combination of one-dimensional and two-dimensional arithmetic coding is employed to ensure that the effect of a transmission error (103, 104) is not propagated to the whole document. Appropriate contexts for the probabilistic models associated with arithmetic coding for one and two-dimensional cases are presented. An error detection scheme (100, 101, 102, 103, 104) to identify the presence of transmission errors is also presented.
