Transmission and detection of multi-channel signals in reduced channel format
First Claim
1. A method comprising:
- receiving video data from a first device via a plurality of channels at a first clock frequency during a video data period;
generating first data from the video data including first bits of the video data but excluding second bits of the video data;
transmitting the first data to a second device over a single channel at a second clock frequency higher than the first clock frequency;
receiving control data from the first device via the plurality of channels at the first clock frequency during a control period;
generating second data from the control data, the second data excluding fixed data of the control data that remain unchanged during the control period; and
transmitting the second data to the second device over the single channel at the second clock frequency.

Abstract
Embodiments of the invention are generally directed to transmission and detection of multi-channel signals in reduced channel format. An embodiment of a method for transmitting data includes determining whether a first type or a second type of content data is to be transmitted, where the first type of content data is to be transmitted at a first multiple of a base frequency and the second type of data is to be transmitted at a second multiple of the base frequency. The method further includes selecting one or more channels from a plurality of channels based on the type of content data, clocking a frequency on the first or second multiple of the base frequency according to the type of content data in the selected channels, modifying the content data to fit within a single output channel, and transmitting the modified data via a single output channel at the chosen multiple of the base frequency.

8. A method comprising:
-
receiving first data corresponding to video data from a first device through a single channel at a first clock frequency; obtaining, from the first data, first bits of the video data; generating second bits of the video data irrespective of the first data; transmitting the first bits of the video data to a second device over a plurality of channels at a second clock frequency lower than the first clock frequency during a video data period; receiving second data corresponding to control data from the first device through the single channel at the first clock frequency; obtaining, from the second data, a first portion of the control data; generating a second portion of the control data including fixed data irrespective of the second data; receiving third data corresponding to data island data from the first device through the single channel at the first clock frequency; de-multiplexing the third data into a first portion of the data island data and a second portion of the data island data, the first portion being compressed and the second portion being not compressed; decompressing the first portion of the data island data into first decompressed data and second decompressed data; and transmitting the first portion of the control data, the first decompressed data, the second decompressed data, and the second portion of the data island data to the second device over a plurality of channels at the second clock frequency. - View Dependent Claims (9, 10, 11, 12, 13)
