Exam 15: Mpeg Compression

What form of MPEG comprises the Video CD (VCD format), the quality of which is analogous to that of the output of a VHS recorder?

Spatial compression compares the changes between the images over time and stores the data that represents only the changes.

Which version of MPEG was not covered in this chapter?

B frames are similar to P frames but are different in that they look both forward and backward to compare pixel blocks.

P frames contain descriptions of how the pixel blocks in the previous frame have changed to create the current frame.

In sampling, each chrominance sample is shared by

Temporal compression uses the same technique as JPEG compression to create an intra picture called an I frame.

Nearly all digital video broadcast uses this standard, which results in DVD quality video and is also used to encode audio and video for broadcast satellite and cable TV.

The formal name of the MP3 audio format is .

MPEG compression utilizes a combination of two different compression schemes, spatial and temporal.
