Algorithm 2: Pricing video transaction algorithm

Input:

v i d e o_{c o n s u m e r}^{o u t p u t}, v i d e o_{c o n s u m e r}^{i n p u t}, p r i_{a v g}^{i n}, p r i_{a v g}^{o u t}

Output: The income of the seller producer is profit_producer, and the amount paid by the buyer is pay_consumer.

initialization:video^input = 0, video^output

v i d e o^{o u t p u t} = \sum_{i = 1}^{m} v i d e o_{i}^{o u t p u t}

v i d e o^{i n p u t} = \sum_{j = 1}^{m + n} v i d e o_{j}^{i n p u t}

ifvideo^output ≥ video^input
