`ABSTRACT
`
`A method and apparatus for multiplexing a plurality of
`channels within a multimedia system includes processing
`that begins by receiving a plurality of channels from a
`multimedia source. The processing then continues by receiv
`ing a plurality of channel selection commands from client
`modules. The processing continues by selecting a channel of
`the plurality of channels for each of the channel selection
`commands to produce selected channels. As such, for each
`channel selection command, a corresponding channel is
`selected from the plurality of channels. The processing
`continues by encoding the selected channels based on a data
`conveyance protocol (e.g., encoding scheme and/or modu
`lation scheme). The encoded channel data is then conveyed
`to a plurality of clients.

`METHOD AND APPARATUS OF
`MULTIPLEXING A PLURALITY OF
`CHANNELS IN A MULTIMEDIA SYSTEM
`
`TECHNICAL FIELD OF THE INVENTION
`

`
`This invention relates generally to communication sys
`tems and more particularly to in-home local area network
`ing.
`

`
`BACKGROUND OF THE INVENTION
`

`transmission protocol. For example, a computer network
`may utilize any one of the Ethernet standards.
`In any type of communication system, a user must have
`the appropriate receiving and possibly transmitting equip
`ment to independently access the communication system.
`For example, a user of a satellite television system must
`have a satellite receiver and a television to receive satellite
`broadcast. If another television is to independently access
`the satellite broadcast, it needs its own satellite receiver. The
`same is true for NTSC broadcast, cable broadcast, etcetera,
`although currently most televisions include an NTSC tuner
`and/or some form of cable tuner.
`With the number of households having multiple television
`sets increasing, and many users wanting the latest and
`greatest Video viewing services. As such, many households
`have multiple satellite receivers, cable set-top boxes,
`modems, etcetera. As is further known, dependent multiple
`access to satellite broadcasts may be achieved by linking
`slave televisions to a master television. The master televi
`sion has full control of and independent access to, the
`satellite receiver while the slave televisions receive what
`ever channel has been selected by the master.
`For in-home Internet access, each computer or Internet
`device has its own Internet connection. As such, each
`computer or Internet device includes a modem. As an
`alternative to each computer having its modem, an in-home
`local area network may be used to provide Internet access.
`In Such an in-home local area network, each computer or
`Internet device includes a network card to access a server.
`The server provides the coupling to the Internet. Currently,
`the cost of a network card is at least as expensive as a 56K
`modem thus, there is no cost savings with such an in-home
`local area network.
`As is further known, in-home local area networks use one
`or more of telephone lines, radio frequencies, power lines,
`and/or infrared connections as the communication medium.
`Such in-home local area networks are typically used to
`facilitate an in-home computer network that couples a
`plurality of computers with one or more printers, facsimile
`machine, etc. As such, entertainment type data transmissions
`(e.g., from VCRs, DVDs, etcetera) are not supported by the
`in-home local area network without having the home spe
`cially wired to support an in-home LAN that transceives
`entertainment type data.
`Therefore, a need exists for a method and apparatus for a
`communication system to overcome the above-mentioned
`issues and to offer additional services within homes.

`
`Communication systems are known to convey data from
`one entity to another. The data may be audio data, video data
`and/or text data. In Such communication systems, the data is
`transmitted via one or more transmission mediums (e.g.,
`radio frequencies, coaxial cable, twisted pair copper wire,
`fiber optic cabling, etcetera) in accordance with one or more
`data transmission protocols. The distance over which the
`data traverses within a communication system may be
`inches, feet, miles, tens of miles, hundreds of miles, thou
`sands of miles, et cetera.
`As is also known, communication systems have two basic
`configurations: wide area networks (WAN) and local area
`networks (LAN). In addition, WAN and/or LAN communi
`cation systems may use a variety of transmission types
`including broadcast transmissions, asymmetrical transmis
`sions, and symmetrical transmissions. In a broadcast com
`munication system, a network hub transmits data to a
`30
`plurality of users with little or no data being transmitted
`from the users to the network hub. Examples of broadcast
`communication systems include radio systems, NTSC (na
`tional television standards committee) television systems
`(e.g., regular TV), high definition television systems, cable
`systems, and satellite systems. In each of these broadcast
`communication systems, a network hub (e.g., radio station,
`television station, et cetera) transmits a broadcast signal.
`Any user within range of the broadcast signal and who has
`an appropriate receiver (e.g., radio, television, etcetera) can
`receive the broadcast signal. Such broadcast systems employ
`a particular data transmission protocol Such as amplitude
`modulation, frequency modulation, ultra-high frequency,
`very high frequency, etcetera.
`Asymmetrical communication systems transmit more
`data in one direction than in another (i.e., one entity trans
`mits to others more than it receives data from each of the
`other entities). An example of an asymmetrical communi
`cation system is the Internet, where web servers transmit
`Substantially more data than they receive from any one user.
`The Internet uses TCP/IP as its data transmission protocol,
`while a variety of physical layer data transmission protocols
`may be used to access the Internet. Such physical layer data
`transmission protocols include asynchronous transfer mode
`(ATM), frame relay, integrated services digital network
`(ISDN), digi
