No. 5,778,187 C2, all of which are incorporated herein by reference in their entirety.
This relates to a method and apparatus for providing audio and/or visual communication services, in real time to a multiplicity of identifiable users on a communications network, such as the Internet. In a preferred embodiment, the invention monitors which users are receiving signals on which one of a plurality of channels and modifies the content of at least some signals in response thereto. A particular application is to provide services akin to multi-channel radio or television with commercial programming content adjusted in accordance with the identity of the individual user.
In the preferred embodiment, the information being delivered is high-quality audio. However, it could also be video, graphics, text or any other type of information that can be transmitted over a digital network. This information is delivered in real time to any number of widely distributed users. It is real time in that for a given channel of information, approximately the same information is being sent at approximately the same time to everyone who is enabled to receive the information.
The distribution architecture provides for the delivery of real-time information to any number of Users distributed throughout a network. As will be described in detail below, the distribution architecture is scalable to allow for efficient delivery of multiple simultaneous information channels in real time to a large number of Users.
The flow of information from Primary Server 20 through the network to User 40 is based on the delivery of a continuous sequence of individual pieces of information, or packets. Thus the distribution architecture implements a form of multicast packet delivery to a group. The group in this case is the set of all Users who are listening to a given channel at a given time. Group membership is dynamic; Users can start and stop listening to a channel at any time.
If the Media Server is directly connected to the same physical network as the User, hardware broadcast or multicast can be used to transmit the packet stream to all Users listening at that time on that network. In this case the Media Servers can translate the incoming packets into broadcast or multicast packets for transmission on the local network. Only a single packet is transmitted at-a-time on the local network and any computer directly connected to the local network can receive that packet. Hardware multicast is built into most networks, and it is lower in overall overhead than hardware broadcast since computers not interested in a transmission do not have to process the packets. In the case that a Media Server is serving a User who is not on the same physical network, a unicast transmission is used to reach that User, which requires a separate packet transmission for each User so connected. In the preferred embodiment, the assignment of Users to Media Servers is done using control transactions among the User 40, Control Servers 50, and Administration Server 60. This system will be described more fully in the following section.
In the preferred embodiment the size of the audio packets being transmitted is variable and can change on a packet-by-packet basis. It is expected that when using compression schemes that have a fixed bit rate, such as ADPCM, all packets for that stream would be the same size. Alternatively when using a variable bit rate compression algorithm, it is expected that packet size would vary so as to establish approximately the same amount of time for each sample. For example, if each packet corresponds to a 20-millisecond segment of speech, this could correspond to 100 bytes during one time period and 200 bytes during another. Additionally, the Media Server may choose to dynamically vary the packet size to accommodate changes in network conditions.
Since the resulting playback of audio information is sensitive to packet loss and network congestion, software running on the various computers that make up this system monitors the ongoing situation and adapts to it in the best possible way. This may involve using different Media Servers and/or lowering the data rate to the User. For example, similar to analog dynamic signal quality negotiation present in many analog radio receivers, the User software may request a lower bitrate until the situation is improved. Also, note that the audio information being delivered to the User is preferably interleaved so that a contiguous segment of the audio stream is distributed for transmission over several packets. As a result, the loss of one packet is spread out over multiple audio samples and causes minimal degradation in audio. Advantageously, a small degree of redundancy may be incorporated within the audio stream to further guard against packet loss.
In addition, the side-bar information discussed above can also include advertising content. FIG. 5 illustrates the provision to the User of two separate streams 32, 34 of packets, one of which may be used for advertising. In this case the insertion of the stream of commercial advertising into the non-commercial stream occurs on the User's computer. FIG. 5 also illustrates packet stream 36, which identifies the User to the system. This enables the system to monitor which Users are listening to which channels, and also allows the system to vary, for example, the advertising content delivered to a User.
Contains information used for channel activation/deactivation. It is sent to Media and
Primary Servers to tell them to carry or stop carrying a specific channel. Media Servers get
the channel from another server in the system hierarchy and Primary Servers get and encode
the feed from the actual input source.
