摘要： Disclosed herein is a method of storing and of progressively transferring a still image so that it can be conveniently previewed during the transfer and so that a user can terminate the transfer at an early stage if the image turns out to be undesirable. The methods of the invention include transforming the image into a plurality of decomposition levels using a discrete wavelet transform. Each decomposition level comprises a plurality of subimages which allow reconstruction of an image representation of the still image. The decomposition levels are transmitted beginning with a base decomposition level providing a low level of image resolution and then proceeding with decomposition levels providing increasingly higher levels of image resolution. Within each decomposition level, rows of the various subimages are arranged or interlaced together in contiguous blocks, so that all data for a single row, at a single decomposition level, is transmitted together. At the receiving end of the transfer, the row blocks are reconstructed and displayed as they are received. The invention enables the initial display of a low resolution image which is gradually updated and sharpened, on a row-by-row basis, until a desired high resolution is achieved. The user may terminate the transfer at any point.

摘要： Modulated data signal having data fields encoded in a data structure defining a bandwidth sharing object for transmission over communications channels. A first data field contains a first stream of first information having a first bandwidth. A second data field contains a second stream of second information having a second bandwidth. The first stream is transmitted simultaneously with the second stream. One or more additional data fields each contain an additional stream of information having an additional bandwidth. The additional streams are transmitted simultaneously with the first and second stream. A bandwidth number indicated in the object is a function of the bandwidth of the first stream, the second stream, and the one or more additional streams. A bandwidth value indicated in the object is less than the total of the first bandwidth, the second bandwidth, and the total bandwidths of the one or more additional streams.

摘要： An improved teleconferencing data capture, encoding, and decoding architecture incorporates the audio encoding and video encoding functions in capture encoder hardware devices, and incorporates the video decoding function in a video decoder hardware device. The video decoder and an audio decoder are able to analyze incoming data packets and are communicably linked to their respective capture encoder devices, or to a single capture encoder device if both audio and video capture and encoding functions are incorporated in a single device, so that the capture and/or encoding functions may be modified during the course of a teleconference.

摘要： An audio data transmission system encodes audio files into individual audio data blocks which contain a variable number bits of digital audio data that were sampled at a selectable sample rate. The number of bits of digital data and the input sampling rate are scaleable to produce an encoded bit stream bit rate that is less than or equal to an effective operational bit rate of a recipient's modem. The audio data transmission system uses computing units which are designed to select an appropriate combination of block size and input sampling rate to maximize the available bandwidth of the receiving modem. For example, if the modem connection speed for one modem is 14.4 kbps, a version of the audio data compressed at 13000 bits/s might be sent to the recipient; if the modem connection speed for another modem is 28.8 kbps, a version of the audio data compressed at 24255 bits/s might be sent to the receiver. The audio data blocks are then transmitted at the encoded bit stream bit rate to the intended recipient's modem. The audio data blocks are decoded at the recipient to reconstruct the audio file and immediately play the audio file as it is received. The audio data transmission system can be implemented in online service systems, ITV systems, computer data network systems, and communication systems.
