Abstract
A method or apparatus of configuring a multi-channel coding device for use as a single-channel coding device is provided. The multi-channel coding device reconfigured as a single-channel coding device performs encoding or decoding of the pixels for a first color channel while substituting the pixels of a second color channel with predetermined (e.g., fixed) values. The reconfigured coding device may output reconstructed pixels of the first color channel but not reconstructed pixels of the second color channel.
Claims18
A method comprising:
- receiving a single-channel mode flag for configuring a video encoder that encodes a multi-channel image having at least first and second color channels;
- when the single-channel mode flag indicates a first mode:
- configuring the video encoder to receive first and second sets of pixels and to encode the multi-channel image based on the received first set of pixels for the first color channel and the received second set of pixels for the second color channel;
- and
- when the single-channel mode flag indicates a second mode:
- configuring the video encoder to receive the first set of pixels and to encode the multi-channel image based on the received first set of pixels for the first color channel and a set of predetermined values for the second color channel.

An electronic apparatus comprising:
- a video encoder capable of encoding a multi-channel image having at least first and second color channels;
- a selection circuit capable of:
- receiving a single-channel mode flag;
- when the single-channel mode flag indicates a first mode:
- configuring the video encoder to receive first and second sets of pixels and to encode the multi-channel image based on the received first set of pixels for the first color channel and the received second set of pixels for the second color channel;
- when the single-channel mode flag indicates a second mode:
- configuring the video encoder to receive the first set of pixels and to encode the multi-channel image based on the received first set of pixels for the first color channel and a set of predetermined values for the second color channel.

A method comprising:
- receiving a bitstream comprising an encoded multi-channel image having at least first and second color channels;
- identifying, based on content of the bitstream, a single-channel mode flag for configuring a video decoder capable of decoding the multi-channel image;
- when the single-channel mode flag indicates a first mode:
- configuring the video decoder to decode the multi-channel image to generate pixels of the first and second color channels and to output the decoded pixels;
- and
- when the single-channel mode flag indicates a second mode:
- configuring the video decoder to decode the multi-channel image to generate pixels of the first color channel and to output the decoded pixels of the first color channel.
