Clocked Video Output :Standalone CVO block for controlling DVI monitor

$

I'm developing an imaging system using the TR4 development kit. Specifically, I'm feeding raw digital data into the FPGA and driving this raw data into a DVI connector(by way of the Bitech HSMC-DVI interface).

I'm using the Clocked Video Output(CVO) ip to drive the DVI interface. The input data is a 8 bit stream from the ADC. Since the Clock Video Output accepts a 24 bit word in the input, I'm parsing the 8 bit ADC output as a single color(i.e. cvo data in is "00000000,ADCOut,00000000" I have attached a block diagram that illustrates the signal flow.

I have two questions on the CVO ip from Altera and I'm wondering if someone can shed some light on these issues

1.To be able to control the HSMC-DVI adapter, wil I need any other VIP block such as Avalon MM or Frame Buffer that run in conjunction with the CVO block
2. I understand that the CVO block will accept data only in the Avalon ST-format. So does this mean that if I can generate the SOP(Start of Packet) and EOP(End of Packet) timing signals (in addition to the DVI clock), I can simply parse a 24 bit word into the CVO? I tried to implement this but it doesn't seem to work.

Thank you for your time in perusal. I hope this information will suffice for understanding the issue. Let me if additional information is required.
