Freshfields is acting for Japanese investment bank Nomura on its bid to find a buyer for its television supply arm Quadriga.
Nomura acquired Quadriga in June last year when it bought the TV rental group Thorn for £980m. Quadriga supplies TV sets to hotels in 13 countries and has been valued by some at £350m.
Barry O'Brien, head of corporate at Freshfields, is leading a team of two on the deal.
Nomura has also appointed fellow investment bank Schroders to advise on its search for a buyer. The deal is expected to be achieved through either an outright sale or the purchase of a minority stake by a strategic partner.
Cable operators as well as media and internet groups are thought to be likely suitors for Quadriga, for example UPC and Time Warner.
At the time of the purchase Nomura thought Quadriga was a potential growth area for the bank but it is selling it to find a new partner to help develop its services.
The sell-off process is expected to last up to three months.
