Interlaced

Interlaced is an adjective meaning formed by interlacing; it can refer to physical weaving, to sequence or signal processing methods in which components are alternatingly combined, or to patterns that appear intertwined.

In weaving, interlacing is the process by which warp and weft threads cross over and under each other to form fabric. The arrangements of interlacing determine weave structures such as plain, twill, and satin, influencing durability, texture, and appearance.

Interlaced video uses two fields per frame: one comprises the odd-numbered lines, the other the even-numbered lines. The fields are displayed alternately, creating a full frame at a given frame rate while transmitting at half the number of lines per field. This was common in analog television to save bandwidth; today most displays use progressive scanning, and interlaced video may require deinterlacing to avoid artifacts like combing.

In computing and data transmission, interleaving spreads data across multiple channels or memory banks to improve throughput or resilience. Memory interleaving and interleaved data streams are used to balance access and reduce latency.

Interlaced thus describes a broad concept of alternating, intertwined arrangements that optimize certain properties such as stability, bandwidth, or parallel data access.
