A BT.656 data stream is a sequence of 8-bit or 10-bit words, transmitted at a rate of 27 Mword/s. Horizontal scan lines of video pixel data are delimited in the stream by 4-byte long SAV (Start of Active Video) and EAV (End of Active Video) code sequences. SAV codes also contain status bits indicating line position in a video field or frame.
The NASA clone was similar to the original NES, but had two slots, a 72-pin on the front and a 60-pin on top. Brazilian manufacturers also produced cartridges, but ran into the problem of having two formats. Hydron company solved the issue by making two-sided cartridges - one side 60-pin, the other 72-pin.

An 8-bit register can store 2 8 different values. The range of integer values that can be stored in 8 bits depends on the integer representation used. With the two most common representations, the range is 0 through 255 (2 8 − 1) for representation as an binary number, and −128 (−1 × 2 7) through 127 (2 7 − 1) for representation as two's complement.
One drawback of this resolution regarding encoding is that the number of lines is not an even multiple of 16, which is a common macroblock size for video codecs. Video frames encoded with 16 × 16 pixel macroblocks would be padded to 640 × 368 and the added pixels would be cropped away at playback. H.264 codecs have this padding and cropping ...
