## Abstract

According to the present subject matter, a cast request is received at a rendering system from a user device over a home network. The cast request is request for casting data from a cast device communicatively coupled to a first network and a third network, onto a display device communicatively coupled to the home network. Thereafter, the rendering system transmits the cast request to a casting system over a second network. In response transmitting the rendering system receives, from the casting system to the requested data. The data is provided to the casting system by the cast device and the data is obtained by the cast device over the first network. The available cast system is automatically discovered by the user device and no configuration or specific software is needed on the user device.

## Claims

### Claim 1

A method comprising:
automatically discovering, by a user device using a native cast discovery functionality of the user device without requiring additional application or hardware changes, a cast device for a direct communication between the user device and the cast device, wherein a casting system is coupled to the cast device through a third network;
receiving, by a rendering router of a rendering system, a cast request over a home network from the user device, wherein the cast request is for casting data from the cast device, which is communicatively coupled to a first network and the third network, onto a display device communicatively coupled to the home network;
transmitting the cast request over a second network to the casting system;
receiving, at the rendering system, the requested casting data from the casting system, wherein the requested casting data is provided to the casting system by the cast device and the requested casting data is obtained by the cast device over the first network.

### Claim 2 (depends on 1)

The method as claimed in claim 1, wherein the requested casting data is received at a variable bit rate.

### Claim 3 (depends on 1)

The method as claimed in claim 1 wherein the user device connects to the rendering system for transmitting the cast request by:
scanning, via the user device, the home network to locate the rendering system;
authorizing the rendering system to communicate with the user device.

### Claim 4 (depends on 1)

The method as claimed in claim 1, wherein the requested casting data is at least one of a) a video stream, b) an audio stream, and c) a combination of an audio stream and a video stream.

### Claim 5 (depends on 1)

The method as claimed in claim 1 further comprising receiving, at the rendering system, a list of casting systems communicatively coupled to the second network along with connection specifications of the listed casting systems.

### Claim 6 (depends on 1)

The method as claimed in claim 1, wherein the first network and the second network are two distinct networks.

### Claim 7

A rendering system comprising:
a rendering router comprising:
a memory;
one or more interfaces; and
one or more processing devices coupled to the memory and adapted to execute instructions stored in the memory to:
receive, via the one or more interfaces over a home network, a cast request from a user device, wherein the cast request is for casting data from a cast device, which is communicatively coupled with a first network and a third network, onto a display device communicatively coupled to the home network;
transmit the cast request to a casting system over a second network, wherein the casting system is communicatively coupled with the cast device through the third network; and
receive, from the casting system, the requested casting data from the casting system,
wherein the requested casting data is provided to the casting system by the cast device,
wherein the requested casting data is obtained by the cast device over the first network, and
wherein the user device, using a native cast discovery functionality of the user device without requiring additional application or hardware changes, automatically discovers the cast device for a direct communication between the user device and the cast device.

### Claim 8 (depends on 7)

The rendering system as claimed in claim 7, further comprising:
a decoder to decode the received data to generate a decoded data; and
a display device integrated with the rendering system, wherein the decoder sends the decoded data to the display device and the display devices displays the decoded data.

### Claim 9 (depends on 7)

The rendering system as claimed in claim 7, wherein the rendering router receives, via the one or more interfaces, a list of casting systems communicatively coupled with the second network along with connection specifications of the casting systems and forwards, over the home network, the list of casting systems along with their connection specifications to the user device.

The method claimed in claim 12, wherein the first network and the second network are two distinct networks.

### Claim 16

A casting system comprising:
a casting router comprising:
a memory;
one or more interfaces; and
one or more processing devices coupled to the memory and adapted to execute instructions stored in the memory to:
