Stream control with different trick-mode protocols

A system comprising:

• a first network device including:
• a receiver to receive content as a first media stream, from a remote network device, using a first network protocol, wherein the first network protocol includes a MPEG-TS (Motion Picture Expert Group-Transport Stream) protocol;
• a processor to convert the first media stream to a second media stream according to a second network protocol, wherein the second network protocol includes a DLNA (Digital Living Network Alliance) protocol;
• a transmitter to transmit the content as the second media stream to a user device;
• and
• a memory to a store a buffer of played content and a buffer of unplayed content, wherein the buffer of played content includes the content transmitted to the user device and the buffer of unplayed content includes the content not transmitted to the user device,
• wherein the receiver is configured 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, wherein the first trick-mode protocol includes a DLNA trick-mode protocol;
• 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, wherein the second trick-mode protocol includes a RTSP (Real Time Streaming Protocol) trick-mode protocol,
• wherein the transmitter is configured to transmit the second trick-mode command to the remote network device,
• wherein the receiver is configured to receive a rewind command according to the first trick-mode protocol from the user device,
• wherein the transmitter is configured to retransmit the content, as the second media stream, from the buffer of played content to the user device in response to receiving the rewind command,
• wherein the receiver is configured to continue to receive the content as the first media stream from the remote network device while the transmitter simultaneously retransmits the content from the buffer of played content to the user device, and the memory is configured to store the received content in the buffer of unplayed content while the transmitter simultaneously retransmits the content from the buffer of played content,
• wherein the receiver is configured to receive a fast-forward command according to the first trick-mode protocol from the user device,
• wherein the transmitter is configured to transmit, in response to the receiver receiving the fast-forward command, the content, as the second media stream, stored in the buffer of unplayed content,
• wherein the process is configured to decrypt media in the first media stream from a first encrypted format that re-encrypt the media into a second encrypted format, wherein the second media stream includes the re-encrypted media in the second encrypted format,
• 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,
• wherein the processor is configured to determine when the buffer of unplayed content is close to empty while the transmitter transmits the content as the second media stream from the buffer of unplayed content, and
• wherein the transmitter is configured to issue a fast-forward command in the second trick-mode protocol to the remote network device when the processor determines that the buffer is close to empty.

A non-transient computer-readable medium including computer-executable instructions, the computer-executable instructions including:

• 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, wherein the first trick-mode protocol includes a DLNA trick-mode protocol;
• 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, wherein the second trick-mode protocol includes a RTSP (Real Time Streaming Protocol) trick-mode protocol, and wherein the instructions to convert the first media stream include instructions to convert the first media stream in real-time;
• instructions to transmit the second trick-mode command to the remote network device;
• instructions to receive a rewind command according to the first trick-mode protocol from the user device;
• instructions to retransmit the content, as the second media stream, from the buffer of played content in response to receiving the rewind command, to the user device;
• instructions to continue to receive the content as the first media stream in the first network device from the remote network device, while simultaneously retransmitting the content, as the second media stream, from the buffer of played content to the user device;
• instructions to store, in a buffer of unplayed content, the content received while simultaneously retransmitting the content, as the second media stream, from the buffer of played content;
• instructions to receive a fast-forward command according to the first trick-mode protocol instructions to receive a fast-forward command according to the first trick-mode protocol from the user device;
• instructions to transmit, in response to receiving the fast forward command, the content stored in the buffer of unplayed content as the second media stream;
• instructions to determine when the buffer of unplayed content is close to empty while transmitting, in response to receiving the fat-forward command, the content stored in the buffer of unplayed content as the second media stream;
• instructions to transmit a fast-forward command in the second trick-mode protocol to the remote network device when determined that the buffer of unplayed content is close to empty;
• instructions to transmit the second media stream to the user device simultaneously with receiving the first media stream;
• instructions to decrypt media in the first media stream from a first encrypted format;
• and instructions to re-encrypt the media into a second encrypted format, wherein the second media stream includes the re-encrypted media in the second encrypted format.
