Some IOS versions may require the text enclosed in quotes “
SV-4K-NA
”. If the IOS
doesn't accept a leading quote in the string, then quotations are not needed.
SV-4K string for North America DMPs: "Cisco SV-4K-NA"
SV-4K string for all other region DMPs: "Cisco SV-4K-ROW"
Example 3. Creating Option 43
Option 43 is a vendor-specific option. For the SV-4K media player, it needs to point to a
specific URL to execute auto-registration, auto-provisioning, and to receive initial
firmware and subsequent upgrades, etc. That URL is
http://x.x.x.x:8080/StadiumVision/dmp_v4/scripts/boot.brs
(where x.x.x.x represents the
IPv4 address of the StadiumVision director server).
Different devices require option 43 information be presented in different formats. The
SV-4K media player requires type-length-value (TLV) format for the data string.
Specifically, the TLV format is constructed in the following manner:
l
The string is built using hex values.
l
The string begins with a two-character hex representation of the option 43 Type
(an option 43 sub-option).
l
The second two-character hex representation is the length of the information
string, expressed in the number of ASCII characters of the string.
l
Following the length value, the ascii string is typed out by using the two-character
hex representation of each character in the string.
For the SV-4K media player, the type designation is type 85 (decimal), expressed as
type 55 (hex).
Example 4. Option 43
For the following URL string:
http://10.10.10.100:8080/StadiumVision/dmp_v4/scripts/boot.brs
The option 43 string would be as follows (except all on one line, without carriage
returns) in the following format:
option 43 hex
value
As shown below, the resulting URL above would be represented by the string below:
option 43 hex
(there is a space here between ‘hex’ and the remainder of the string)
553E687474703A2F2F31302E31302E31302E3130303A383038302F5374616469756D
566973696F6E2F646D705F76342F736372697074732F626F6F742E627273
Using the description above and the ASCII lookup table below, the first characters of
the string would be explained in the following way:
