摘要： The invention relates to the generation of error correction data for available data packets and to the reconstruction of missing data packets based on available data packets and available error correction data. In order to enable an efficient error correction, the data packets are distributed at an encoding end to at least one block of data symbols, each data symbol being of equal size. Then all data symbols of a respective block are used in an encoding operation for forming a respective one of at least one error correction symbol for this block. At a decoding end, received data packets are distributed again to a block of data symbols and missing data packets are reconstructed based on these data symbols and on error correction symbols associated to the block.

摘要： To support a forward error correction scheme, in which a code of the forward error correction scheme is employed at a transmitting end for encoding data for a transmission to a receiving end, the transmitting end compresses at least one binary parity check matrix associated to the employed code of the forward error correction scheme. The transmitting end then provides the compressed binary parity check matrix for a transmission to the receiving end. The receiving end receives the compressed binary parity check matrix and decompresses it for use in a forward error correction based on encoded data received from the transmitting end.

摘要： A sender in a wireless network may adjust the encoding bit rate of the transmitted content and/or the transmission bit rate of the content based on the predicted future channel throughput at a predicted future geographical position of a client mobile device, such as a cellular telephone. By appropriately adjusting the bit rate prior to the client mobile device experiencing the predicted low throughput, the likelihood of continuous content consumption by the client mobile device, even while experiencing the predicted low throughput conditions, may be increased. The prediction may be performed at the network side and/or at the client mobile device side.
摘要翻译：无线网络中的发送者可以基于在诸如蜂窝电话的客户端移动设备的预测的未来地理位置处的预测的未来信道吞吐量来调整所发送的内容的编码比特率和/或内容的传输比特率。通过在客户端移动设备经历预测的低吞吐量之前适当地调整比特率，即使在经历预测的低吞吐量条件的情况下，客户端移动设备的连续内容消费的可能性也可能增加。该预测可以在网络侧和/或在客户端移动设备侧进行。

摘要： For the notification of a receiving device about a forthcoming transmission session, an identifier of one of various possible types of identifiers in a transmission session is mapped to a transmission session identifier field. This field is used for notifying the receiving device. Further, a repetition value is added to the transmission session identifier field, which indicates whether the forthcoming transmission session is new or not. Further, the receiving device may release context data stored for a particular transmission session identifier, if an acquisition of data in transmission sessions identified by the transmission session identifier can be terminated.

摘要： An improved system and method for permitting a transmitting electronic device to indicate explicitly which streams in a multimedia stream being transmitted should not be synchronized or should include a specified amount of synchronization jitter. The present invention aids the receiving device in understanding the stream characteristics. The present invention also allows the receiving device to make an informed decision as to whether an synchronization jitter value should be used when synchronizing two or more streams. For certain applications such as uni-directional video sharing or video PoC, the sending device of the stream can indicate that the receiving device doesn't perform any or limited synchronization for better media quality.
