Challenging research issues:
-
Low bandwidth (ISDN) Internet VOD
-
wavelet video compression
-
Video Internet Protocol (VIP)
-
new IP protocol with low overhead, guaranteed ordered packet arrival, and support for interactive video
-
Contents indexing
-
unification with text databases (metadata), automatic caption capture, conversion, storage
-
speech recognition with automatic video indexing via text-converted audio layer
-
High-volume servers with ATM trunk: Variable Bit Rate (VBR) to Constant Bit Rate (CBR) conversion, optimized bandwidth provisioning, multiple audio/video stream scheduling (discussed later in this tutorial)
