Does ADV7340 requires Licensing before programming?

Dear Sir/Madam,

We have designed the hardware where we are using ADV7340 IC for PAL(720x576i @ 50fps) Video Encoder.

Does this IC require purchasing of License?  Authorized vendor are saying this IC will be shipped with License.

Why License is required for ADV7340 ? Even though this IC is I2C configurable.

What is difference between ADV7340 and ADV7341 ? Even though both are technically compliant.

Regards,

Ankit Sohni
