摘要： A method and system for optimizing performance of a read buffer and a write buffer in a disc media having a feature requiring apparently simultaneous reading and writing. The method includes alternately writing data to the disc media from the write buffer during a write time tW and reading data from the disc media to the read buffer during a read time tR. The read time and the write time are generally separated by a jump time tJ. The write time is selectively controlled so that it is optimized in accordance with respect to the front end read speed, the decoding bit rate, the front end write speed of the recordable media device and the encoding bit rate.

摘要： A method and device for editing to a picture a group of pictures (GOP) in a DVD media without decoding and encoding of an MPEG encoded signal. The method includes the steps of: marking a user selected end picture to identify a selected segment of the encoded signal to be edited; automatically identifying an actual end picture for the selected segment based on a position of the user selected end picture relative to at least one other picture within the encoded signal; and performing an edit function on an actual segment delimited by the actual end picture.

摘要： A method for format conversion includes providing a first interlaced video signal including non-progressive video of a first resolution, downconverting fields of the first resolution to fields of a second resolution, and combining and interlacing the fields at a third resolution. The video signal is transmitted at the third resolution. The video signal of the third resolution is deinterlaced to form a progressive format video. The progressive format video is converted to the first non-progressive resolution by alternately adjusting position of the progressive format of the third resolution up and down to make upper and lower fields, respectively, of the first resolution for display.

摘要： A differential trellis decoding method for convolutional codes is provided which eliminates from candidacy half of the transitions in each round that it is used, thereby obviating the need for weight calculations for the eliminated transitions. The method is based on a decomposition of the code trellis into fully connected bipartite graphs and the observation that the symmetry of the bipartite graphs of the trellis permits the comparison and selection process for one state to influence the comparison and selection process for other states in the bipartite graph. This method results in a reduced number of operations and hence a reduced complexity for convolutional decoding.

摘要： A hybrid scheme for controlling transmission errors in digital data communication systems. Normally, data blocks with a small number of parity digits for error detection are transmitted. When the presence of errors is detected, the retransmissions are not the original data blocks but some properly selected blocks for correcting errors in those erroneously received data blocks which are stored in a buffer at the receiver. The retransmitted blocks are formed based on the original data blocks and error-correcting codes with an invertible property. When such blocks are received, they are used to recover the original data blocks either by an inversion operation or by a decoding process.

摘要： A method (200) and system (100) for performing a trick mode on a video signal. The method includes the steps of receiving (210) a trick mode command, in response to the trick mode command, repeating (212) a picture in the video signal to form a trick mode video signal in which the picture contains a display indicator; setting (214) the display indicator of the picture being repeated to a predetermined value; and setting (216) the display indicators of subsequent repeated pictures of the picture being repeated to the predetermined value. In one arrangement, the trick mode can be a freeze trick mode, and the picture to be repeated can be a bidirectional predictive picture. In addition, the display indicator can be a temporal reference field having an integer value.

摘要： The Universal Packet Loss Recovery System (UPLRS) is capable of recovering end-to-end network packet losses to obtain reliable end-to-end network delivery of multimedia streaming content over IP networks where packet losses appear above the transport layer. The UPLRS incorporates the use of Packet Forward Error Correction Coding (FEC) with packet interleaving processing prior to transport. Packet FEC is an error correction coding method at the packet level to improve link transmission reliability. At the source end of the packet-switching network, the Packet FEC scheme encodes a stream of transport multimedia content packets by including redundant packets in the stream to allow for the recovery of lost packets by the Packet FEC decoder at the user end of the packet-switching network. Since lost packets appear only above the transport layer in the IP network protocol stack, Packet FEC can be viewed as a transport layer or an application layer coding method.
摘要翻译：通用分组丢失恢复系统（UPLRS）能够恢复端到端网络分组丢失，以通过IP网络获得可靠的端到端网络传输多媒体流内容，其中分组丢失出现在传输层上方。 UPLRS在传输之前结合使用分组前向纠错编码（FEC）与分组交织处理。分组FEC是分组级别的纠错编码方法，以提高链路传输的可靠性。在分组交换网络的源端，分组FEC方案通过在流中包括冗余分组来编码传输多媒体内容分组流，以允许分组FEC解码器在分组的用户端恢复丢失的分组切换网络。由于丢失的分组仅出现在IP网络协议栈中的传输层之上，所以分组FEC可以被视为传输层或应用层编码方法。

摘要： A method for media disaster recovery when recording data to re-writable disk media can include defining a sequence of recordable units (RUs) in the re-writable disk media wherein each RU in the sequence has a maximum data capacity. Data can be sequentially recorded in each RU, in sequence. When data has been completely recorded in an RU, RU metrics can be computed. Subsequently, the computed RU metrics can be stored in an RU information file in the re-writable disk media. Significantly, responsive to a media disaster, for example a power outage, a disaster RU can be identified in the RU information file. Specifically, the disaster RU can be an RU in which data had been incompletely recorded during the media disaster. Upon identifying the disaster RU, the sequential recording of data can resume in an RU next in sequence to the disaster RU.
