A sending device uses multiple data rates on different channels to reliably send data packets and receivers use NACKs to request retransmission of missing or mangled ... 07/14/05 - 20050154965 - Transmission apparatus, transmission control program, and transmission method A transmission apparatus includes: a communication unit performing transmission and reception of an encoded data packet with other terminals; a redundant code generating unit generating a redundant code packet for restoring a loss of the data packet; a redundant code control unit controlling a band used by the redundant code ... 07/07/05 - 20050149831 - Systems and methods for decoding of partially corrupted reversible variable length code (rvlc) intra-coded macroblocks and partial block decoding of corrupted macroblocks in a video decoder The invention is related to methods and apparatus that recover usable video data from partially corrupted data. Embodiments inspect corrupted data packets and identify the location or locations of an error, whether the corrupted data packet contains data expected to be error-free, and whether the error-free data should be used. ... 07/07/05 - 20050149830 - Satellite controlling system having function of distributing satellite state data based on reception environment and method thereof Provided are a satellite controlling system having a function of distributing satellite state data based on a reception environment and a method thereof. The satellite controlling system distributes and transmits satellite state data transmitted from a satellite according to preference and authority of the user and the characteristics of a ... 07/07/05 - 20050149829 - Ip packet error handling apparatus and method using the same, and computer readable medium having computer program for executing the method recorded thereon An error handling apparatus and method, and a computer-readable medium storing a computer program for executing the error handling method are provided. According to the method, in a case where a number of errors in object IP packets that are consecutively detected, each within a first predetermined time since a ... 06/23/05 - 20050138532 - Apparatus and method for concealing errors in a frame An apparatus and method for concealing an error in a frame using multiple frames are provided. A frame decoder decodes a bit stream of a received frame, and determines whether there is a defective macro block in the decoded frame. A buffer stores at least two previous frames decoded by ... ### FreshPatents.com Support |
