Abstract:
1. A method for video data extension, comprising: receiving a video bitstream at a data processor, the video bitstream comprising Serial Digital Interface (SDI) video data received at a first bit-rate; wherein the video bitstream comprises a first video stream comprising first serial data and a second video stream comprising second serial data; obtaining a first clock signal from the first video stream and obtaining a second clock signal from the second video stream, the first clock signal and the second clock signal indicative of the first bit rate; generating a third clock signal; converting the first serial data into first parallel data and converting the second serial data into second parallel data; segmenting via the data processor the video bitstream into a plurality of segments by dividing the first parallel data into a plurality of first data packets based on the first clock signal and the third clock signal, and dividing the second parallel data into a plurality of second data packets based on the second clock signal and the third clock signal, wherein the maximum number of bits in any segment of said plurality of segments is n with n a positive integer greater than one, and wherein at least some of said plurality of segments comprise n-bit data segments; appending via a control module an additional segment to each of said plurality of segments for providing an extended SDI video bitstream, wherein the additional segment comprises m-bit information, wherein m is a positive integer greater than one; arranging the first data packets and second data packets in an alternate manner for forming said plurality of segments; and transmitting via a transmitter module the extended SDI video bitstream at a second bit-rate, wherein the second bit-rate is equal to or greater than (n+m)/n times the first bit-rate, wherein the third clock signal is based on the second bit-rate.
