摘要： A system to provide a multipoint processing terminal and a multicast bridging terminal to provide mixing, switching, and other processing of media streams under the control of H.323 components. Application Programming Interfaces defined for the multipoint processing terminal provide a multipoint control unit with the capability to change the default behavior of the multipoint processing terminal by allowing the multipoint control unit to control the routing audio and video streams in the multipoint processing terminal and control the media formats in a multipoint conference. Multipoint processing acceleration functionality is provided by providing interfaces to allow hardware accelerated implementations of multipoint processing terminals. The multicast bridging terminals enables clients using one type of control signaling and media streaming to join other conferences using different types of control signaling and media streaming by receiving audio or video data from an incoming media stream and performing any processing necessary to transform the media stream from the incoming stream data format to the outgoing stream data format.

摘要： The buffer of a programmable video recorder includes a backing store having a plurality of discrete temporary files that are configured to store non-byte streamed data, such as ASF data. The data stream includes a number of data samples that are each assigned a time stamp upon receipt. Each data sample is then assigned and written to a temporary file based on a corresponding duration assigned to each of the temporary files. The backing store operates like a moving window as the oldest temporary files are replaced with the newest temporary files.

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： A computing system connected to storage medium and one or more rendering devices receives streamed multimedia data. The multimedia data is encoded in a format, such as an Advanced Streaming Format, that is conducive to storing the multimedia data in files having appended indexes. Upon receiving the multimedia data, the multimedia data is written to file structures within the storage medium, while at the same time maintaining a real-time index for each file in a shared memory. After a file is complete, the real-time index is appended to the completed file and deleted from the shared memory. When a request for data is received that pertains to a file that does not have an appended index, the computing system obtains any necessary file index information from the real-time index in the shared memory, thereby enabling the requested data to be accessed.

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.

摘要： A computer system includes a local non-volatile data storage medium and a visual display device. A still image is stored as a compressed data file in a multi-resolution compression format on the non-volatile data storage medium. The multi-resolution format is of a type that allows efficient progressive decompression and display of the selected still image. The computer system includes a data processor programmed to decompress the compressed data file, to produce successive versions of the selected still image at progressively increasing resolutions, and to display the successive versions on the visual display device. The computer system has a data retrieval medium through which the data processor retrieves the compressed data file from the local non-volatile data storage medium. The data retrieval medium has a data transfer rate that is at least as fast as the data processor can decompress the compressed data file and display the successive versions of the selected still image.
