METHOD AND SYSTEM FOR ACHIEVING HIGHER VIDEO THROUGHPUT AND/OR QUALITY

摘要

Digital data, including audio and video, may be communicated at increased data rates by utilizing non-data signal channels in cables to communicate additional data. For data transmission, a reformatter receives data in a first format adapted for communication over the data signal channels of a cable. The reformatter may convert the received data into a second format with one or more additional data signals. The reformatter then utilizes non-data signal channels of the cable to carry the additional data signals. An example non-data signal channel may include a clock signal channel, and the reformatter may fold a clock signal into one or more of the data signals to allow for clock recovery downstream. Data may also be split into two or more subsets and each subset encoded separately, for example with two or more data encoders such as legacy HDMI encoders.

1. A method for communication of digital data over a cable, the method comprising:
receiving digital data in a first format for transmission through a cable adapted to a first protocol, wherein the cable comprises at least one data signal channel and at least one non-data signal channel; determining if a first data rate of the first format exceeds a maximum data rate of the first protocol; and in response to the determination that the first data rate exceeds the maximum data rate of the first protocol:
reformatting the digital data to a second format for transmission through at least the data signal channel and the non-data signal channel; andoutputting the reformatted digital data for transmission through the cable via the data signal channel and the non-data signal channel.
