Abstract
A method and apparatus for generating a mosaic program guide. The method comprising; generating I frames from a coded video bit stream; placing each I frame into one of a multiplicity of mosaic windows; and combining the multiplicity of mosaic windows into a mosaic video frame.
Claims22
A method of generating a mosaic program guide comprising;
- generating I frames from a coded video bit stream;
- placing each I frame into one of a multiplicity of mosaic windows;
- and
- combining said multiplicity of mosaic windows into a mosaic video frame.
4 The method of claim 3, wherein the I frame of each mosaic window is replaced with a later decoded I frame of the same program.
The method of claim 4, wherein said later decoded I frame is the next I frame of the same program.
An apparatus for generating a mosaic program guide comprising:
- means for generating I frames from a coded video bit stream;
- means for placing each I frame into one of a multiplicity of mosaic windows;
- and
- means for combining said multiplicity of mosaic windows into a mosaic video frame.
A receiver for generating a mosaic program guide comprising:
- means for receiving an input signal and generating a coded bit stream;
- a de-multiplexer adapted to receive said coded bit stream and adapted to generate a coded video bit stream;
- a video decoder adapted to select I frame data from said coded video bit stream and decode and generate a sequence of I frames.
A receiver for generating a mosaic program guide comprising:
- a first tuner and demodulator adapted to receive an input signal and adapted to generate a first coded bit stream;
- a first a de-multiplexer adapted to receive said first coded bit stream and adapted to generate a first coded video bit stream;
- a first video decoder adapted to receive said first coded video bit stream and generate a sequence of video frames from a single program;
- a second tuner and demodulator adapted to receive said input signal and adapted to generate a second coded bit stream;
- a second a de-multiplexer adapted to receive said second coded bit stream and adapted to generate a second coded video bit stream;
- and
- a second video decoder adapted to select I frame data from said second coded video bit stream and decode and generate a sequence of I frames.
