Abstract: Embodiments presented herein are directed to “content linking multicast streaming” The embodiments connect a listener to over-the-air (OTA) broadcast radio content using an Internet Protocol (IP) multicast stream of the broadcast radio content when, for example, (i) a traditional broadcast radio receiver is not available, or (ii) an OTA broadcast radio signal that carries the content is not available. For example, when recovery of the OTA broadcast radio signal by a car radio is not possible because of poor reception or because the car radio is not configured with a suitable broadcast radio tuner, the embodiments generate a link to a multicast stream of the OTA broadcast radio content (also referred to as a “multicast broadcast radio stream” or simply a “multicast stream”), and provide the link to the car radio. The car radio can then access the multicast stream of the OTA broadcast radio content using the link.

Abstract: In some embodiments, color and contrast enhancement video processing may be done in one shot instead of adjusting one of color and contrast enhancement, then the other, and then going back to the first one to readjust because of the second adjustment. In some embodiments, global lightness adjustment, local contrast enhancement, and saturation enhancement may be done at the same time and in parallel. Lightness adjustment improves visibility of details for generally dark or generally light images without changing intended lighting conditions in the original shot, and is used to enhance the range of color/saturation enhancement. Local contrast enhancement done in parallel improves visual definition of objects and textures and thus local contrast and perceived sharpness.
