摘要： This disclosure describes audio decoding techniques for decoding audio information that needs to be properly clocked. In accordance with this disclosure, the number of audio samples in decoded audio output can be adjusted to compensate for an estimated error the in decoder clock. That is to say, rather than adjust the decoder clock to synchronize the decoder clock to the encoder clock, this disclosure proposes adding or removing audio samples from the decoded audio output in order to ensure that the decoded audio output is properly timed. In this way, the techniques of this disclosure can eliminate the need for an adjustable or controllable clock at the decoding device, which can save cost and/or allow legacy devices that do not include an adjustable or controllable clock to decode and output audio information that needs to be properly clocked.

摘要： Communication methods, buffer management methods, communication systems, and communication devices for mobile communications using acknowledgement-based protocols, such as TCP. Communication buffer memory includes free and committed memory, with copies of transmitted messages awaiting acknowledgement stored in committed memory of transmit buffer. Memory controller monitors communication buffer state and, if free memory is less than a memory threshold, controller extracts TCP ACKNUM from a received host message. The TCP ACKNUM acknowledges transmitted message copies having ACKNUMs of lesser ordinality, and memory controller identifies and denominates the committed memory storing acknowledged messages as free memory, potentially avoiding deadlock.
摘要翻译：通信方法，缓冲管理方法，通信系统以及使用基于确认的协议（例如TCP）进行移动通信的通信设备。通信缓冲存储器包括自由和提交的存储器，其中发送的消息的副本等待发送缓冲器的已提交存储器中的确认。内存控制器监控通信缓冲区状态，如果空闲内存小于内存阈值，控制器将从接收的主机消息中提取TCP ACKNUM。 TCP ACKNUM确认具有较小顺序的ACKNUM的传输的消息副本，并且存储器控制器将存储已确认消息的已提交存储器标识并标记为可用存储器，潜在地避免死锁。
