<p>Method and apparatus for converting a stream of incoming serial video data which is received frame by frame and is formatted with all data bits arriving together for each pixel into digital PWM video as a sequence of likeweighted bits. Incoming video data is temporarily stored in a digital memory. A controller organises the data in the memory into a plurality of buffers, each buffer having only bits of like weight. The data is collected as groups within the buffers. The data is then coupled to a display device as the groups of likeweighted bits. As groups of the shortest durationbit weight are formed, they are coupled to the display and thus need to be stored only for the fraction of a frame time. Therefor the size of the buffer requied for storing the video data for PWM is less than an entire frame.</p> |
