Abstract: A data transmission method and system for enhanced channel coding efficiency of a DisplayPort interface is disclosed. One method comprises transmitting a plurality of coding units for each micro-packet in each of one or more lanes of a DisplayPort Main Link from a DisplayPort transmitter, wherein each of the coding units comprises: a group of m symbol chunks, each symbol chunk including four 8-bit symbols, wherein m is 2 or 4; and an n-bit code data indicator that precedes the group of m-symbol chunks, wherein n is 2 or 4, and wherein the n-bit code data indicator indicates a content type of the m symbol chunks.

Abstract: USB transmission and reception devices are provided. A USB transmission device comprises a first interface to receive display port (DP) data via N lanes at a first link rate, wherein N is an integer greater than 1; and a switching re-timer including a plurality of de-serializer circuits to de-serialize the received DP data, a plurality of decoder circuits to decode the de-serialized DP data, a plurality of multiplexer circuits to multiplex the decoded de-serialized DP data received via each of the N lanes into 1/M lanes, wherein M is an integer greater than 1, a plurality of encoder circuits to encode the multiplexed DP data, and a plurality of serializer circuits to serialize the encoded multiplexed DP data and output the serialized multiplexed DP data on each of the N/M lanes at a second link rate, the second link rate being equal to the first link rate multiplied by M.

Abstract: A data transmission system includes a transmitter having a first switching re-timer and a receiver having a second switching re-timer. The first switching re-timer is configured to double a link rate per lane and halve the number of lanes, and the second switching re-timer is configured to halve the doubled link rate and double the halved number of lanes.
