Described is multi-layered frame-compatible video delivery. Provided is a decoding method for multi-layered frame-compatible video delivery. The method comprises the following steps: receiving input video signals of input frames encoded in a multi-layer format mode in an encoder comprising one or more processors, wherein the multi-layer format comprises a coding basic layer frame, which comprises even number arrays and odd number arrays of first viewpoint, wherein the even number arrays and odd number arrays are parallelly arranged and woven as a pack; and a coding enhanced layer frame, which comprises even number arrays and odd number arrays of first viewpoint, wherein the even number arrays and odd number arrays are parallelly arranged and woven as a pack; decoding and unpacking the coding basic layer frame so as to generate encoding basic layer first viewpoint and encoding basic layer second viewpoint; decoding and unpacking the coding enhanced layer frame to generate encoding enhanced layer first viewpoint and encoding enhanced layer second viewpoint; and finally sampling the encoding basic layer first viewpoint and encoding basic layer second viewpoint so as to generate output frame with frame compatible mode.
