Default: P (program stream)
Example: STREAMTYPE T (transport stream)

PROFILE

This command is used to select a desired resolution for the encoded video. It also sets the

optimal defaults for other parameters, such as bit rate. The allowable settings are QQCIF, QCIF, CIF,
1/2, D1.

Default: 1/2

Example Command:

PROFILE

1/2

(sets resolution to 1/2 D1)

Note:

Since the Profile command selects defaults for other settings, it should be issued before any other

commands relating to the encoded MPEG stream.

QQCIF

80x60

QCIF

160x120

CIF

352x240

1/2

352x480

720x480

FPS

[n]

Sets encoded frames/second. Where n = frames per second of the video stream (i.e. 30, 15, 10, 5,

3, 2, 1)

GROUPLEN[

Sets frame spacing between I frames. Where n = number of frames between I-Frames.

Default: 30.

A larger GROUPLEN and smaller FPS increases the startup time of the decoder.

RES

<D1|2/3|1/2|SIF|QSIF|VGA|QVGA|QQVGA>

Sets encoder resolution. QSIF, VGA, QVGA, and QQVGA are not supported by MPEG2

(Encoder 1).

QQVGA - 160x120 (cropped horz)

QSIF - 176x120

QVGA - 320x240 (cropped horz)

SIF - 352x240

1/2 - 352x480

VGA - 640x480 (cropped horz)

D1 - 720x480
