Video memory control device |
摘要 |
A video memory control device for a two-field video signal that is buffered in a memory having capacity for one field. The phase of the writing to and reading from the memory may be such that the fields are being swapped on output. To display the correct sequence without losing any fields, the reading address for one field is delayed by 1H or the reading address for the other field is advanced by 1H dependent on the detected phase. A similar technique may alternatively be applied to the writing side.
