Abstract: PROBLEM TO BE SOLVED: To provide methods and systems for resizing multimedia content on the basis of quality and rate information.SOLUTION: Encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information to a multiplex module. The multiplex module determines whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects the segments to be resized on the basis of the quality and rate information.

Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus to improve error resilience by generating a directory including header information. SOLUTION: This invention relates to a method and an apparatus to improve error resilience in processing a multimedia bitstream. According to the method 300, a directory of header information is generated for a multimedia bitstream (S315). Directory information includes packet header information associated with the multimedia bitstream. The directory information may be transmitted to a receiver along with the multimedia bitstream (S320). A receiver of the multimedia bitstream and the directory can utilize the header information to identify and locate packets within the received bitstream and subsequent to erroneous data. By identifying and locating packets that may otherwise be discarded, the receiver may be able to improve error recovery and decoding of multimedia data. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device capable of using a probabilistic feedback to optimize a distribution of a multicast content about the content distribution, within a network environment. SOLUTION: The method is provided for transmitting data from a server to a plurality of receiving terminals. The method includes the processes of transmitting the data from the server to the plurality of the receiving terminals and generating a random response value by each receiving terminal. The method, further, includes a processing of comparing the response value with acknowledged value by each receiving terminal, and to transmit an acknowledgment signal from the selected receiving terminal to the server. The selected receiving terminal is a part of the plurality of the receiving terminals in which the response value has a selected relation with respect to the acknowledged value.

Abstract: In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.
