Abstract: Dynamic control by a source device of sink buffer size for audio and/or video streaming over an error-prone channel. The sink buffer size may be determined based on a type of application for a media stream being transmitted from the source device to the sink device for presentation. The techniques may select a buffer size that is smaller for gaming applications, larger for interactive media applications, and even larger for non-interactive media types. The techniques adjust the time delta between a shared clock reference and time reference values of a transport stream that are used by the sink device to determine decoding or presenting of media frames of the transport stream relative to a shared clock reference. In addition, the techniques may account for transceiver latency at the source device due to scanning or multiple concurrent connections.

Abstract: A method of performing dual-mode rate control for an access point in a wireless communication system includes a single-user mode of operation and a multi-user mode of operation. In the single-user mode, a basic rate for a station is determined based on channel conditions. In the multi-user mode, a rate for a plurality of stations is determined using tracking. The tracking includes performing a sounding for the plurality of stations. An initial multi-user current rate is then set equal to a function of a number of users and the basic rate. A transmission is sent to the plurality of stations using the current rate. A packet error rate (PER) is detected during transmission to the plurality of stations. The current rate is adjusted based on the PER. After rate adjustment, either sounding is triggered or the method returns to sending a transmission using the current rate.

Abstract: Techniques for identifying and enhancing colors in a digital image associated with one or more target color shades. In an embodiment, the target color shades may include a shade of blue associated with the sky, a shade of green associated with outdoor foliage, or the color red. In an embodiment, the blue chroma (Cb) and red chroma (Cr) coordinates of a pixel are evaluated to determine whether to apply an enhancement factor. The enhancement factor may incorporate an exposure index (EI) auxiliary enhancement factor, a color temperature (D) auxiliary enhancement factor, and a luminance (Y) of each pixel. Further aspects for implementing the techniques in software and hardware are disclosed.
