Abstract:
Methods and systems for processing video data are disclosed herein and may include determining a first video format associated with video data to be displayed on a first video display communicatively coupled to a single mobile multiple media processor that supports a plurality of display formats. The single mobile multiple media processor may be integrated within a mobile device. An amount of the video data that is transferred from memory to the first video display, by a DMA controller, may be restricted based on the determined first video format associated with the video data to be displayed on a first video display. Only the restricted amount of the video data that is to be displayed by the first video display may be transferred from the memory to the first video display by the DMA controller.
