In order to optimise access to varied services, the method comprises: a radio and/or television channel request step, referred to as a requested channel, then a determination step of at least two services representative of said requested channel, said services being received via distinct networks, a reception step of said at least two services, and an automatic selection step of one of said services according to at least one service quality parameter associated with each of said services at reception. ## Claims ### Claim 1 A method of selection of audio and/or video services, wherein said method is implemented by a hybrid receiver receiving said audio and/or video services from distinct networks of different types to which said hybrid receiver is connected via distinct interfaces, said method comprising the steps of: determining of at least two of said audio and/or video services representative of a same channel, and being received via distinct networks, according to at least one similarity parameter that comprises a correlation of a variation of signals corresponding to said at least two of said audio/and or video services, and selecting one of said determined at least two of said audio and/or video services according to at least one service quality parameter associated with each of said at least two of said audio and/or video services, where at least one of said quality of service parameter associated to at least one of said at least two of said audio and/or video services is obtained by extracting signalling information from a signalling server, said signalling being associated with each of said at least one of said at least two of said audio and/or video services. ### Claim 2 (depends on 1) The method according to claim 1, wherein said at least one of said quality of service parameters comprises at least one from a first group of service parameters, said first group comprising: presence of an error correction code associated with said at least two of said audio and/or video services, a correction power of an error correction code associated with said at least two of said audio and/or video services, a binary bit-rate of said at least two of said audio and/or video services, a variation of service bit-rates of said at least two of said audio and/or video services, and global information on characteristics of networks used to transport said at least two of said audio and/or video services. ### Claim 3 (depends on 1) The method according to claim 1, wherein said at least one of said quality of service parameter comprises at least one from a second group of service parameters, obtained during decoding said at least two of said audio and/or video services, said second group comprising: a number of errors detected in decoding said at least two of said audio and/or video services, a number of missing packets of said at least two of said audio and/or video services, a number of packets of said at least two of said audio and/or video services, received out of time, a number of packets of said at least two of said audio and/or video services, received out of sequence, and a variation in arrival time of packets from said at least two of said audio and/or video services. ### Claim 4 (depends on 1) The method according to claim 1, wherein said step of selecting is performed depending on several quality of service parameters associated with each of said at least two of said audio and/or video services. ### Claim 5 (depends on 4) The method according to claim 4, further comprising weighting of said several quality of service parameters, said selecting being performed as function of said weighting. ### Claim 6 (depends on 1) The method according to claim 1, wherein said step of selecting further comprises eliminating of at least one of said at least two of said audio and/or video services of which at least one of said quality of service parameter has not attained a determined minimum value. ### Claim 7 (depends on 1) The method according to claim 1, wherein said step of selecting further comprises taking into account at least one secondary parameter associated with each of said at least two of said audio and/or video services. ### Claim 8 (depends on 7) The method according to claim 7, wherein said at least one secondary parameter comprises at least one of: a coding type parameter of said at least two of said audio and/or video services, a compression rate of said at least two of said audio and/or video services, a source server geographical localisation parameter of said distinct networks, and a parameter indicating a number of network equipment hops to a source server of said distinct networks. ### Claim 9 (depends on 1) The method according to claim 1, wherein said at least one similarity parameter comprises at least one of: a service name, a service identifier, an identifier of a channel associated with a service, and a source identifier. ### Claim 10 (depends on 1) The method according to claim 1, further comprising obtaining said at least one similarity parameter, by: determining variation of at least part of video signals corresponding to said at least two of said audio and/or video services and obtained during decoding, and correlating between said variation of at least part of video signals corresponding to said at least two of said audio and/or video services. ### Claim 11 (depends on 1) The method according to claim 1, wherein said step of selecting is performed following a channel change request. ### Claim 12 (depends on 1) The method according to claim 1, wherein said step of selecting is performed following a predetermined event, said predetermined event being at least one of: a change in composition of a list of audio and/or video services, a connection to a new network, a disconnection from a network, and a modification of at least one of said quality of service parameter.
