Sample sets and new down-sampling schemes for linear component sample prediction

The disclosure regards cross-component prediction and methods for deriving of a linear model for obtaining a first-component sample for a first-component block from an associated reconstructed second-component sample of a second-component block in the same frame, the method comprising determining the parameters of a linear equation representing a straight line passing through two points, each point being defined by two variables, the first variable corresponding to a second-component sample value, the second variable corresponding to a first-component sample value, based on reconstructed samples of both the first-component and the second-component; and deriving the linear model defined by the straight line parameters; wherein said determining the parameters uses integer arithmetic.

Dynamic codec adaptation
11546596 · 2023-01-03 · ·

Embodiments are described for dynamically adapting video encoding to maintain a nearly stable frame rate based on processor capabilities and bandwidth, for example, by varying a quantization parameter. The quality of the encoded video can be varied to maintain the nearly constant frame rate, which may be measured from the number of encoded video frames being transmitted over a network interface.

MANAGEMENT OF THE HTTP ADAPTIVE STREAMING OF AN ITEM OF DIGITAL CONTENT IN SCREEN SAVER MODE
20220417311 · 2022-12-29 ·

A method for managing the HTTP adaptive streaming of an item of digital content within a multimedia stream player terminal in a local communication network is disclosed, the multimedia stream player terminal being associated with a terminal for rendering the item of digital content. On detection of an active state of a screen saver mode of the rendering terminal, such a management method implements a progressive reduction of a video rendering quality of the streamed item of digital content, and maintains an audio rendering quality of the item of content.

DEVICE WITH DYNAMIC TRANSCODE THROTTLING
20220417528 · 2022-12-29 ·

Dynamic transcode throttling methods and devices for processing resource management and thermal mitigation in electronic devices such as eyewear devices. An electronic device monitors its temperature and, responsive to the temperature, configures a transcoding service to operate at different rates. A frame delay module is configured to add a delay between read frames prior to the transcoding service. This enables the electronic device to consume less power when temperatures are too high in order to provide thermal mitigation and can be performed without powering down the electronic device.

Smoothing bit rate variations in the distribution of media content

Methods and apparatus are described for delivering streams of media content in ways that smooth out the peaks that might otherwise occur due to the bit rate variations that result from encoding of the media content. This is accomplished by controlling the timing of the transmission of packets of the encoded media content.
