Q.2 a. Discuss
data streams characteristics for Continuous Media. (9)
b. A node X in a network transmits packets to
another node Y assuming Poisson process with parameter l =
2. If transmission is carried out for 30 minutes, find out the time interval to
make it strongly periodic. (9)
Q.3 a. Discuss various aspects of music Instrument
Digital Interface (MIDI) standard including devices. (9)

lasting for one hour. What is the data rate of the channel to transmit / broadcast
online? (9)
Q.4 a. Discuss various characteristics of video signal representation, i.e.,
visual representation, transmission and digitization in detail. (9)
b. How many CDs of 690 MB size would be needed
for a video (RGB) of 2 hours duration and no compression technique has been
used and no sound is there in it. It is assumed that display unit is super VGA

Q.5 a. What are the basic compression techniques?
Discuss each one of them. (9)
b. For
a video (RGB) of one hour which is encoded in MPEG-1 standard, what would be
the storage requirement? For what resolution of the display device is it
suitable? Assume aspect ratio of device is 4/3 and motion frequency is 20 Hz. (9)
Q.6 a. Discuss MPEG standard in detail. (9)
