In general, start in left column and read from left to right. †† Default template.

Template

This read-only field shows the template (if any) that is currently

 

applied using the Load Template button. If a template is applied it will

 

display Parameters Match or Parameters Do Not Match (depending on

 

whether or not changes have been made). Select Load Template >

 

None to clear a "parameters do not match" message.

 

 

Profile

Each profile targets a specific class of applications. The profile you

 

select must be supported by the decoder. For example, StreamPlayer

 

and QuickTime support both profiles.

 

• Baseline – Typically used for applications with limited computing

 

resources, for example video conferencing and mobile

 

applications. Maximum backwards compatibility and lower CPU

 

requirements for decoder.

 

• Main – Default. Originally intended for broadcast and storage

 

applications providing better quality and more efficient

 

bandwidth usage.

 

 

Resolution

Sets the video encoding resolution (the width and height respectively

 

of the video on a PC screen. See Table 5 below for all resolutions.

 

 

Target Bit Rate

32,000–10,000,000 bits/sec. Constant bit rate. Default = 750,000.

(bits/sec)

This number, in 1000 bits/sec increments, represents how much data

 

the VBrick will send out each second to carry video to a player. The

 

word target is used because the appliance can vary its bit rate slightly

 

in response to the amount of detail in the movie or camera output.

 

The more data the appliance sends in one second, the more clearly

 

the details of the video will be seen on a player. It is not always

 

desirable to send the most possible data, since that requires a large

 

network "pipe" (connection). The trade-off is the level of detail in the

 

video with the use of smaller network connections. The encoder tries

 

to encode the video at a quality that will (on average) match the

 

Target Bit Rate. The larger the number, the better the quality but this can

 

potentially limit the number of clients that can connect to the encoder.
