Protocol for uncompressed multimedia data transmission
First Claim
1. A method for dynamically updating addresses of daisy-chained devices in an uncompressed multimedia communication system, comprising:
- receiving at a downstream device uncompressed multimedia data serially transmitted over a single communication channel from an upstream device, the data in a data format that specifies upstream device address;
detecting at the downstream device that the address of the upstream device has changed; and
automatically adjusting the address of the downstream device based on the upstream device address.

Abstract
A serial transmission protocol and architecture are provided that can be used to transmit uncompressed multimedia (e.g., video/audio/control data) over a high speed serial forward communication channel. A backward channel is also provided, for communicating control data. The protocol is implemented with a flexible packet format that supports all different modes of video data, and also supports 24 bit and 30 bit video data (or higher). An example application where the architecture and protocol can be used is a home entertainment multimedia system. A mechanism to implement EDID pass-through and protocols such as HDCP is also provided.

9. An uncompressed multimedia communication system for dynamically updating addresses of daisy-chained devices, comprising:
-
an interface for receiving at a downstream device uncompressed multimedia data serially transmitted over a single communication channel from an upstream device, the data in a data format that specifies upstream device address; and a control processor for detecting at the downstream device that the address of the upstream device has changed, and for automatically adjusting the address of the downstream device based on the upstream device address. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A machine-readable medium encoded with instructions, that when executed by one or more processors, cause the processor to carry out a process for dynamically updating addresses of daisy-chained devices in an uncompressed multimedia communication system, the process comprising:
-
receiving at a downstream device uncompressed multimedia data serially transmitted over a single communication channel from an upstream device, the data in a data format that specifies upstream device address; detecting at the downstream device that the address of the upstream device has changed; and automatically adjusting the address of the downstream device based on the upstream device address. - View Dependent Claims (18, 19, 20, 21, 22, 23)
