Transmission and detection of multi-channel signals in reduced channel format
First Claim
1. A method for transmitting data comprising:
- determining whether a first type or a second type of content data is to be transmitted, wherein 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, wherein the content data is high definition audio visual data, the content data comprising a video data period, a control period, and a data island period;
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, wherein;
for video data of the second type, data transmission comprises elimination of a channel that does not contain meaningful data,for control period data of the second type, the data transmission comprises omitting data in one of the channels that is fixed to a constant, wherein the data from the other channels is transmitted at the second multiple of the base frequency via the single output channel, andfor data island data of the second type, data transmission comprises selecting all channels and compressing the data to fit into two channels, wherein the compressed data is transmitted at the second multiple of the base frequency via the single output channel.

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.

6. A method for receiving data comprising:
-
receiving an incoming data stream on a single data channel; detecting a first type or a second type of content data from the received data stream, wherein the data is received at a first multiple or a second multiple of a base frequency depending on the type of content data, wherein the content data is high definition audio visual data, the content data comprising a video data period, a control period, and a data island period; clocking the content data at a frequency at the first or second multiple of the base frequency according to the type of content data in the channel; decoding the content data; and converting the content data into a plurality of channels at the base frequency, wherein the converting is based on the type of content data, wherein; for video data of the second type, converting the content data into a plurality of channels comprises inserting a channel containing non-meaningful data, for control period data of the second type, converting the content data into a plurality of channels comprises inserting a channel that is fixed to a constant, and for data island data of the second type, converting the content data into a plurality of channels comprises decompressing at least a portion of the data to fit into multiple channels. - View Dependent Claims (7, 8, 9)
