A processor and a memory connected to the processor store instructions executed by the processor to collect playback statistics including audio attributes or video attributes associated with playback of specified content from multiple devices, aggregate the playback statistics, and establish a playback configuration for the specified content based on the playback statistics. The specified device here may be a type of content player or server.

Generating playback configurations based on aggregated crowd-sourced statistics

A processor and a memory connected to the processor store instructions executed by the processor to collect playback statistics including audio attributes or video attributes associated with playback of specified content from multiple devices, perform an aggregation of the playback statistics, wherein the aggregation comprises a distribution of the audio attributes or video attributes associated with the playback of the specified content, identify a mean value of the distribution, and establish a playback configuration for the specified content based upon the mean value. Aggregation of audio attributes or video attributes may be for a specified device type, wherein the specified device type is a category of playback devices to which a device belongs. The specified device here may be a type of content player.

A server includes a processor and a memory connected to the processor to store instructions executed by the processor to collect playback statistics from network connected content players, perform an evaluation of the playback statistics, and establish a playback configuration for specified content based upon the evaluation of the playback statistics. A request for the playback configuration for the specified content is received from a network connected content player. The playback configuration for the specified content is transferred to the network connected player.

Apparatus and method for content playback utilizing crowd sourced statistics

An approach is provided for determining a program clock reference (PCR) value validity, for avoiding inaccurate variable delay reference (VDR) values, and for avoiding a mismatch in a data packet between a sequence number and a packet number for a wireless display extension. The approach involves determining to generate a data packet carrier having an optional PCR value, a VDR) value, and a validity indicator. The approach may further involve processing the data packet carrier to determine whether the data packet carrier has the optional PCR value. The approach may also involve causing, at least in part, a surrogate PCR value to be generated based, at least in part, on a determined absence of the optional PCR value from the data packet carrier.

Method and apparatus for low jitter clock recovery in wireless display extensions

Systems, devices and methods are described including specifying a jitter response control parameter, receiving multiple timestamp pairs. A maximum jitter of the timestamp pairs may be determined along with an elapsed time, and a clock frequency may be adjusted if the maximum jitter is less than the elapsed time divided by the jitter response control parameter. The jitter response control parameter may be adjusted in response to changes in die jitter of the input A/V signal. Further, one or more Proportional-Integral-Derivative (PID) controller coefficients may be adjusted in response to the evaluated jitter of the timestamp pairs.

Adaptive PID controller for audio/video clock recovery

Systems and methods are described including receiving a clock signal, using rational clock divider (RCD) logic to generate a lower frequency clock signal in response to the received clock signal, and using the second clock signal to drive software timer logic and generate media timestamps.

Rational clock divider for media timestamps and clock recovery functions

An integrated circuit (IC) die includes a plurality of edge counters. Each edge counter is provided to detect at least one change in signal level at a respective location on the IC die. The IC die is in communication with a memory and also includes an event recording circuit on the IC die provided to store states of the counters in the memory.
