Patent number: 10171539Abstract: A special rendering mode for the first few seconds of play out of multimedia data minimizes the delay caused by pre-buffering of data packets in multimedia streaming applications. Instead of pre-buffering all incoming data packets until a certain threshold is reached, the streaming application starts playing out some of the data packets immediately after the arrival of the first data packet. Immediate play out of the first data packet, for example, results in minimum delay between channel selection and perception, thereby allowing a user to quickly scan through all available channels to quickly get a notion of the content. The immediate play out is done at a reduced speed.Type: GrantFiled: August 26, 2016Date of Patent: January 1, 2019Assignee: AT&T INTELLECTUAL PROPERTY II, L.P.Inventors: Mathias R. Kretschmer, James H. Snyder

Patent number: 10014977Abstract: A system and method for transmitting data over a channel, in which the data are categorized in at least two different categories. For example, the data are categorized according to the effect on perceived degradation on the data when error mitigation is performed on the data. Corrupted data of the first category are replaced using a first replacement method, such as retransmission and forward error correction. The corrupted data of the second category are replaced using a second replacement method different from the first replacement method, e.g., error mitigation or interpolation.Type: GrantFiled: September 21, 2015Date of Patent: July 3, 2018Assignee: AT&T Intellectual Property II, L.P.Inventors: Peter Frank Driessen, Mathias R. Kretschmer, Schuyler Reynier Quackenbush, James H. Snyder
