B-Frame GOP
Structure

open [IBB]

closed [BBI]

An open structure means a B-frame can refer to
an I-frame in the preceding GOP.  “Closed” means
all B-frames in a GOP can only refer to I and P-
frames within the GOP.  Using “open” will lead to
slightly better compression.  “Closed” is useful
when you know you plan to put chapter markers
in the content (the DVD standard requires that
any GOP used as a chapter marker must be a
closed GOP).  The default is “Open.”

B-frame Interval

1

– 3 (

3

)

# of B-frames between P-frames minus 1. Setting
“1” means no B-frames. Setting “3” means 2 B-
frames between every P-frame.

Audio Delay

0

– 1000ms

Can be used with “video delay” to adjust
audio/video offset when the A/V sync of the
source is a little off. This is typically set to 0.

Video Delay

0

– 1000ms

Can be used with “audio delay” to adjust
audio/video offset when the A/V sync of the
source is a little off. This is typically set to 0.

Output Interface

Ethernet

Where the output stream goes to. In this RPS
only Ethernet output is supported.

Video Passthru

HDMI

Where the passthrough video is sent to. In this
RPS only HDMI passthrough is supported.

Output Format

MPEG-2 TS

RTP

Selects between MPEG-2 TS encapsulated streams
(sent over UDP), or RTP.

Dest IP Address

192.168.x.y

(192.168.0.6)

The IP address that the encoder is streaming to.

Dest Port

0 – 9999 (

5004

)

The port that the encoder is streaming to.

ASI Bitrate

0 – 20000k (

12000k

)

Governs the transport stream rate. In general, it
is good to give a 30-50% margin over the video
bitrate. This parameter is only valid when
“Output Format” is “MPEG-TS.”

Note 1: Encode Resolutions Supported:

WQVGA (320x180), QVGA (320x240), SIF (352x240), CIF (352x288), 2-CIF (352x576), 640x360, VGA
(640x480), 4-CIF (704x576), 16:9 PAL (1024x576), D1 PAL (720x576), D1 NTSC (720x480),

720p (1280x720), XGA (1280x1024), 1080p (1920x1080), De-interlace, Follow input

“Follow input” = Generate encoder resolution based on capture resolution detected

“De-interlace” = Follow input and de-interlace

Note 2: GOP Sizes Supported:

10, 12, 15, 25, 30, 50, 60, 100, 120, 200, 240 frames
