Set Output Resolution for VGA Input
This advanced command is only intended for one specific case; in almost all cases the default setting of ‘auto’
should be used.
This command is designed to be used in the following scenario: When using a VGA video‐source with a
resolution of 1280 x1024 where you require that the TV screen be completely filled with picture, without the use
of black borders. In this case set the ZvPro 250 to ‘720p’ output resolution and it will generate a picture that’s
1280 x 720, completely filling the TV screen without the use of black bars‐ but cropping off the top portion of
the incoming picture. To avoid losing picture information, the incoming source must be formatted so that the top
~310 lines of the picture are blank.

Setting Program (HDTV / Virtual Channel) Information
Within a single RF‐Channel, there can be many actual “HDTV channels” – that’s what is actually tuned by the TV.
In MEPG2, each of the HDTV channels is called a Program. Each program is assigned a number of parameters,
with the most important ones being the major and minor HDTV (virtual) channel number – the actual numbers
that are used to tune the channel on the HDTV.
Set Channel Name
The channel name is displayed on the HDTV whenever the channel is changed, or when information is
requested. This can be very useful, especially when deploying multiple ZvBox channels.
Syntax
set mpeg2 program {video1} short‐channel‐name “name” name <= 7 characters
factory default: ZvCast
set mpeg2 program {video1} long‐channel‐name “name”
name <= 64 characters
factory default: Welcome to ZeeVee ZvCast
Example:
ZvCli$ set mpeg2 program video1 short‐channel‐name "new"
Success
ZvCli$
set mpeg2 program video1 long‐channel‐name "new channel"

Set HDTV Channel Number
Tuning to an analog channel is as simple as entering the RF channel number associated with that channel. Not
so simple with HDTV channels. Since it is possible to pack multiple digital channels into a single RF channel slot,
a new scheme for ‘tuning’ to those channels was developed. Each program has an HDTV channel number
(major and minor) associated with it. That’s the number entered at the HDTV to find this channel. It was a way
to help with the analog to digital conversion, where digital channels were actually in a different RF slot than
