Codification

Procedure through which information (data, sound and image) is converted into an appropriate format at the level of the transmission channel used. A television signal may be codified into an analogue format (e.g. PAL or NTSC) or into a digital format (MPEG-2 or MPEG-4, e.g.).

Conditional Access

Technical measure and/or arrangement whereby access to the protected service in an intelligible form is made conditional upon prior individual authorisation. As a rule, conditional access systems associated to paid television resort to encryption, but other methods may also be used to avoid non-authorized access.
