## Abstract

A method provides pre-rendered information messages for display by a peripheral display unit connected to a base station over a data link. The method involves detecting that a data connection between the base station and the peripheral display unit is available, sending pre-rendered information messages from the base station to the peripheral display unit, and storing the pre-rendered information messages at the peripheral display unit for display in response to a status detected at the peripheral display unit. The base station may perform the pre-rendering of information messages in response to variation in configuration information relating to the peripheral display unit. The pre-rendered information messages may be paired with peripheral display unit statuses and the peripheral display unit may be configured so that, in the event that a particular status is detected, the corresponding pre-rendered information message is displayed without requiring data transmission from the base station.

## Claims

### Claim 1

A method of providing pre-rendered information messages for display by a peripheral display unit when the peripheral display unit is connected to a base station over a data link, the method comprising:
detecting that a data connection between the base station and the peripheral display unit is available;
sending pre-rendered information messages from the base station to the peripheral display unit; and
storing the pre-rendered information messages at the peripheral display unit for display in response to a status detected at the peripheral display unit.

### Claim 2 (depends on 1)

The method of claim 1, further comprising pre-rendering the information messages by the base station in response to variation in configuration information relating to the peripheral display unit to produce the pre-rendered information messages.

### Claim 3 (depends on 1)

The method of claim 1, wherein the pre-rendered information messages are stored in a non-volatile memory at the peripheral display unit.

### Claim 4 (depends on 1)

The method of claim 1, wherein the pre-rendered information messages are paired with peripheral display unit statuses and the peripheral display unit is configured so that, in the event that a particular status is detected, the corresponding pre-rendered information message is displayed without requiring data transmission from the base station.

### Claim 5 (depends on 1)

The method of claim 1, further comprising sending information relating to messages to be rendered by the peripheral display unit to the base unit once availability of a connection between the peripheral display unit and the base station is detected.

### Claim 6 (depends on 1)

The method of claim 1, further comprising determining messages, by the base station, for sending to the peripheral display unit.

### Claim 7 (depends on 2)

The method of claim 2, wherein the pre-rendering takes account of one or more of:
language settings of the base unit and/or the peripheral display unit;
chromatic aberration of the peripheral display unit optics;
focal parameters of the peripheral display unit optics;
mura artefact correction;
curvature and/or angling of a display screen;
accessibility settings; and/or
one or more pixel value parameters of image or video data currently being displayed or anticipated to be displayed by the peripheral display unit.

### Claim 8 (depends on 1)

The method of claim 1, wherein sending the pre-rendered information messages comprises sending the pre-rendered information messages in response to one or more of:
the base station and/or the peripheral display unit being initialised;
software for the base station and/or the peripheral display unit being updated;
a language setting for the base station and/or the peripheral display unit being changed; and/or
a graphical display setting being changed.

### Claim 9 (depends on 1)

The method of claim 1, wherein the method is executed periodically.

### Claim 10 (depends on 1)

The method of claim 1, wherein the pre-rendered information messages stored on the peripheral display unit are updated when a change in one or more parameters of image or video data currently being displayed by the peripheral display unit is detected.

### Claim 11 (depends on 1)

The method of claim 1, wherein the method is executed in response to detection of a particular status by the base station and/or the peripheral display unit.

### Claim 12

A system for providing pre-rendered information messages for display by a peripheral display unit when the base station and the peripheral display unit are connected to one another over a data link, the system comprising:
a base station;
a peripheral display unit having a memory; and
a data link between the a base station and the peripheral display unit; and

the peripheral display unit is configured to store the pre-rendered information messages in the memory and to display the pre-rendered information messages in response to a status detected at the peripheral display unit.

### Claim 13 (depends on 12)

The system of claim 12, wherein the base station is configured to pre-render the information messages in response to variation in configuration information relating to the peripheral display unit.

### Claim 14

one or more pixel value parameters of image or video data currently being displayed or anticipated to be displayed by the peripheral display unit.

### Claim 19 (depends on 12)

The system of claim 12, wherein the system is configured to send the pre-rendered information messages to the peripheral display unit in response to one or more of:
