## Abstract

Embodiments disclosed include a method and a system. The method includes receiving a first media stream, in a first network device from a remote network device, using a first network protocol. The may method include converting the first media stream in real-time to a second media stream according to a second network protocol and transmitting the second media stream to a user device. The method may include receiving a first trick-mode command according to a first trick-mode protocol from the user device, wherein the first trick-mode command includes rewind, fast forward, or pause. The method may include converting the first trick-mode command into a second trick-mode command according to a second trick-mode protocol and transmitting the second trick-mode command to the remote network device.

## Claims

### Claim 1

A method comprising:
receiving a first media stream, in a first network device from a remote network device, using a first network protocol;
converting the first media stream to a second media stream according to a second network protocol;
transmitting the second media stream from the first network device to a user device;
receiving a first trick-mode command according to a first trick-mode protocol from the user device, wherein the first trick-mode command includes a rewind, a fast forward, or a pause command;
converting the first trick-mode command into a second trick-mode command according to a second trick-mode protocol different than the first trick-mode protocol; and
transmitting the second trick-mode command to the remote network device.

### Claim 2 (depends on 1)

The method of claim 1, wherein converting the first media stream includes converting the first media stream in real-time, and transmitting the second media stream to the user device occurs simultaneously with receiving the first media stream.

### Claim 3 (depends on 2)

The method of claim 2, wherein converting the first media stream includes converting the first media stream in a set-top box.

### Claim 4 (depends on 2)

The method of claim 2, further comprising:
receiving the second media stream in a user device; and
rendering media on a display in the user device based on the second media stream.

### Claim 5 (depends on 4)

The method of claim 4, further comprising:
receiving the first trick-mode command from the user; and
transmitting the first trick-mode command from the user device to the first network device.

### Claim 6 (depends on 2)

The method of claim 2, further comprising:
decrypting media in the first media stream from a first encrypted format; and
re-encrypting the media into a second encrypted format, wherein the second media stream includes the re-encrypted media in the second encrypted format.

### Claim 7 (depends on 6)

The method of claim 6,
wherein the first network protocol includes a MPEG-TS (Motion Picture Expert Group-Transport Stream) protocol,
wherein the second network protocol includes a DLNA (Digital Living Network Alliance) protocol,
wherein the first trick-mode protocol includes a DLNA trick-mode protocol, and
wherein the second trick-mode protocol includes a RTSP (Real Time Streaming Protocol) trick-mode protocol.

### Claim 8

A system comprising:
a first network device including:
a receiver to receive a first media stream, from a remote network device, using a first network protocol;
a processor to convert the first media stream to a second media stream according to a second network protocol; and
a transmitter to transmit the second media stream to a user device,
wherein the receiver receives a first trick-mode command according to a first trick-mode protocol from the user device, wherein the first trick-mode command includes a rewind, a fast forward, or a pause command,
wherein the processor converts the first trick-mode command into a second trick-mode command according to a second trick-mode protocol different than the first trick-mode protocol, and
wherein the transmitter transmits the second trick-mode command to the remote network device.

### Claim 9 (depends on 8)

The system of claim 8, wherein the processor is configured to convert the first stream in real-time, and the transmitter is configured to transmit the second media stream to the user device simultaneously while the receiver receives the first media stream.

### Claim 10 (depends on 8)

The system of claim 8, wherein the first network device includes a set-top box.

### Claim 11 (depends on 8)

The system of claim 8, further comprising the user device including a receiver to receive the second media stream, and a display to display media based on the second media stream.

### Claim 12 (depends on 11)

The system of claim 11, wherein the receiver in the user device is configured to receive the first trick-mode command from a user, the user device further comprising a transmitter to send the first trick-mode command from the user device to the first network device.

### Claim 13 (depends on 8)

The system of claim 8, wherein the processor of the first network device is configured to decrypt media in the first media stream from a first encrypted format and re-encrypt the media into a second encrypted format, wherein the second media stream includes the re-encrypted media in the second encrypted format.

### Claim 14 (depends on 13)

The system of claim 13,
wherein the first network protocol includes a MPEG-TS (Motion Picture Expert Group-Transport Stream) protocol,
wherein the second network protocol includes a DLNA (Digital Living Network Alliance) protocol,
wherein the first trick-mode protocol includes a DLNA trick-mode protocol, and
wherein the second trick-mode protocol includes a RTSP (Real Time Streaming Protocol) trick-mode protocol.

### Claim 15

A non-transient computer-readable medium including computer-executable instructions, the computer-executable instructions including:
instructions to receive a first media stream, in a first network device from a remote network device, using a first network protocol;
instructions to convert the media stream to a media stream according to a second network protocol;
instructions to transmit the second media stream to a user device;
instructions to receive a first trick-mode command according to a first trick-mode protocol from the user device, wherein the first trick-mode command includes a rewind, a fast forward, or a pause command;
instructions to convert the first trick-mode command into a second trick-mode command according to a second trick-mode protocol different than the first trick-mode command; and
instructions to transmit the second trick-mode command to the remote network device.

### Claim 16 (depends on 15)

The computer-readable medium of claim 15, wherein the instructions to convert the first media stream include instructions to convert the first media stream in real-time, the computer-readable medium further including instructions to transmit the second media stream to the user device simultaneously with receiving the first media stream.

### Claim 17 (depends on 16)

The computer-readable medium of claim 16, further comprising:
