Entropy Coding: This parameter allows the user to set the Entropy coding. CABAC (Context-based
Adaptive Binary Arithmetic Coding) or CAVLC (Context-Adaptive Variable-Length Coding). CABAC is
a more efficient choice and should be used if the H.264 decoder can support it. Entropy coding
resizes the DCT (Discrete Cosine Transform) coefficients according to the number of times they
appear in the bit stream. The most frequently repeated coefficients are expressed as small as
possible, decreasing the total number of bits needed to represent a single frame.
IDR Pictures: This parameter allows the user to enable / disable insertion of IDR (Instantaneous
Decoder Refresh) frames. An IDR frame is a special type of I-frame in H.264. An IDR frame specifies
that no frame after the IDR frame can reference any frame before it. This makes seeking the H.264
frames easier and more responsive for the decoder.
Latency Mode: This parameter allows the user to set the latency mode. Possible values are Min,
Low and Normal.
MBAFF (Macro Block-Adaptive Frame-Field) Mode: This parameter allows the user to enable /
disable the MBAFF mode.

IPTV ENCODER

Output Configuration
IP Address: This parameter allows the user to select a streaming output IP address for the IPTV
Encoder. Can be a Multicast or Unicast address.
UDP Port Number: This parameter allows the user to select the destination UDP port number of the
streaming output.
TTL: This parameter allows the user to set the TTL (Time To Live) field of the output IP packets.
Total TS Bit Rate: This parameter allows the user to select the output TS Bitrate in kbps.
The 3080UEP will automatically adjust the bitrate for video based on audio and other PID settings.
