Method to optimize the data stream between a router and a multimedia unit
First Claim
1. A method for optimizing at least one sub-data stream between a router and a multimedia unit, the router receiving a data stream including a plurality of sub-data streams forming a plurality of services, the at least one sub-data stream between the router and the multimedia unit being a sub-data stream of the plurality of sub-data streams, at least one service of the plurality of services being formed of at least a portion of the plurality of sub-data streams, a subset of said portion being transmitted to the multimedia unit, and said subset including the at least one sub-data stream, the method comprising:
- defining a dataset representing a profile of the multimedia unit, the dataset including at least one of a spoken language and an access subscription of a user,transmitting the dataset to the router,configuring a filter in the router according to the transmitted dataset,receiving, by the router, a request from the multimedia unit for the at least one service,selecting said portion of the plurality of sub-data streams forming the at least one requested service,filtering, by the router, the subset from said portion of the plurality of sub-data streams based on the transmitted dataset, and,transmitting the filtered subset forming the requested at least one service to the multimedia unit.

Abstract
Even if high speed are available between the router and the multimedia unit through the IP line (up to 24 Mbits/sec), this is still the bottleneck in term of data transfer. Indeed in practice the vast majority of IP users have access speed between 2 to 5 Mbits/sec and the development of other services (telephony, videoconference, push VOD, game) are bandwidth consuming. It is now an object of the invention to propose a solution to reduce the data flow between the router and the multimedia unit over IP line.
This is achieved by a method to optimize the data stream between a router and a multimedia unit, the router receiving at least one data stream forming a service and comprising several sub-streams from which part of them are alternatively used by the multimedia unit, the method comprising the steps of:
- defining a set of data representing the multimedia unit'"'"'s profile,
- transmitting this set of data to the router,
- filtering by the router the unnecessary sub-stream according the given profile,
- sending the remaining sub-streams to the multimedia unit.
