A system for adaptive audio video (AV) stream processing may include at least one processor and a switch device. The switch device may be configured to route AV traffic to the processor, and to receive AV traffic from the processor and provide the AV traffic to a client device via one or more channels. The processor may monitor a transcoder buffer depth and depths of buffers associated with channels over which the AV traffic is being transmitted. The processor may adaptively modify one or more attributes associated with the AV traffic based at least on the monitored buffer depths. For example, the processor may adaptively adjust a bit rate associated with transcoding the AV traffic based at least on the transcoder buffer depth. The processor may utilize the depths of the buffers associated with the channels to adaptively adjust the amount of AV traffic provided for transmission over the channels.

Message prioritization may be provided. First, a message may be received and a priority level may be calculated for the message. If the message is not rejected for having a priority lower than a predetermined threshold, the message may be placed in a first priority queue. Next, the message may be de-queued from the first priority queue based upon the calculated priority level for the message. Distribution group recipients corresponding to the message may then be expanded and the priority level for the message may be re-calculated based upon the expanded distribution group recipients. Next, the message may be placed in a second priority queue. The message may then be de-queued from the second priority queue based upon the re-calculated priority level for the message and delivered.

Disclosed herein, among other things, are methods and apparatus for providing a time-stamp based controller for synchronization of sink or source sampling rate with external packet rate. A method for wireless communications includes receiving a transmission of a packet using a wireless transceiver of an electronic device, and using a processor of the electronic device to read a first value of a system timer and store the first value as an arrival time-stamp. The packet is decoded and processed by the processor, and sent to an output. When the processed packet is sent, a second value of the system timer is read, adjusted and stored as a departure time-stamp. The arrival time-stamp and the departure time-stamp are used to calculate an adjustment stimulus for a sample rate actuator of the electronic device. The sample rate actuator is configured to maintain synchronization of sampling rate with an external packet rate.

A system and method for data synchronization in a circular buffer architecture is disclosed. Embodiments describe a data synchronization mechanism, focusing on the efficient management of the circular buffer between producer and consumer processes. In an embodiment, a method uses a lapping technique to facilitate parallel processing without the need for locking mechanisms, ensuring continuous data flow and real-time responsiveness. Further, the method uses modulated lap indicators and associated paperclip indicators at each buffer slot to track access history and resolve race conditions. The method determines valid access sequences through indicator comparison, enabling reliable conflict resolution, computes warp distances to guide synchronization updates, and dynamically adjusts buffer configurations in response to system events. The method also preserves access states across interrupts or context switches, enabling seamless continuation of operations. The method provides a lock-free synchronization mechanism that enables precise state tracking and efficient coordination of concurrent buffer access.
