Abstract
According to examples, an apparatus may include a video switch, a video scaler, and a video splitter. The video splitter may access an input video stream, in which the input video stream is at a first resolution, split the accessed input video stream into a first video stream and a second video stream, send the first video stream to be displayed at the first resolution through the video switch, and send the second video stream to the video scaler. The video scaler may scale the second video stream to a second resolution that differs from the first resolution and output the scaled second video stream to be displayed at the second resolution.
Claims20
An apparatus comprising:
- a video switch;
- a video scaler;
- and
- a video splitter to:
- access an input video stream, wherein the input video stream is at a first resolution;
- split the accessed input video stream into a first video stream and a second video stream;
- send the first video stream to the video switch;
- send the second video stream to the video scaler;
- wherein the video switch is to output the first video stream to a first device, to be displayed at the first resolution, and
- wherein the video scaler is to:
- scale the second video stream to a second resolution that differs from the first resolution;
- and
- output the scaled second video stream to a second device, to be displayed at the second resolution.
A system comprising:
- a computing device;
- a video encoder;
- a video scaler;
- a video switch;
- and
- a video splitter to:
- split an input video stream into a first video stream and a second video stream, wherein the input video stream is at a first resolution;
- send the first video stream to the video switch;
- send the second video stream to the video scaler,
- wherein the video switch is to output the first video stream to a display device, to be displayed at the first resolution;
- wherein the video scaler is to:
- scale the second video stream to a second resolution that differs from the first resolution;
- and
- send the second video stream to the video encoder, wherein the video encoder is to encode and output the encoded second video stream to the computing device, to be displayed at the second resolution.
A method comprising:
- receiving, by a video splitter, an input video stream, wherein the input video stream is at a first resolution;
- splitting, by the video splitter, the input video stream into a first video stream and a second video stream;
- sending, by the video splitter, the first video stream to a video switch and the second video stream to a video scaler;
- outputting, by the video switch, the first video stream to a local display device;
- scaling, by the video scaler, the second video stream to a scaled video stream;
- sending, by the video scaler, the scaled video stream to a video encoder;
- encoding, by the video encoder, the scaled video stream;
- and
- outputting, by the video encoder, the encoded scaled video stream to a video conferencing application that is to output the encoded scaled video stream to remote display devices.
