In this case we see that the service “CRX-001” is unencrypted, uses
MPEG2 video encoding, and has single channel (mono) audio encoded
with an 8-bit companding scheme with a sampling rate of 16kHz.
To start decoding a service the user should “double click” the
appropriate service name. Service names are always highlighted in bold
text in the main player window. If the service is unencrypted the main
decoder window will be launched.
5.1 Encrypted Streams
If the service selected is being encrypted by upstream hardware, then
the user will be prompted for the reciprocal key. The video stream player
can detect from information in the stream whether ABS or AES
encryption is being used. It will present a window appropriate to the type
of encryption. For ABS the following window will appear:
This requires the 32-bit ABS decryption key to be entered as 8
hexadecimal characters. This is not case sensitive.
