On screen displays associated with remote video source devices
View Patent ↗In some embodiments, an apparatus includes interface circuitry to receive signals including video signals and drawing commands, and a command interpreter to receive the drawing commands and provide on screen display (OSD) signals in response to the drawing commands. Video processing circuitry processes the received video signals to provide processed video signals, and a blender to blend the OSD signals and the processed video signals to produce blended video signals including the OSD signals and the processed video signals. Other embodiments are described and claimed.
1. An apparatus comprising:
interface circuitry to interface with a network outside of the apparatus;
a display management module to identify potential video source devices on the network and outside of the apparatus to potentially provide video signals to the apparatus through the interface circuitry and to direct generation of an on screen display (OSD) menu including symbols to represent the potential video source devices; and
receiver circuitry to receive a user selection of at least one of the potential video source devices from the OSD menu,
wherein the display management module is further configured to provide a token to a selected video source device corresponding to the user selection, and to allow an OSD graphics stream from the selected video source to be displayed responsive to receiving the token back from the selected video source device and validating the token.
2. The apparatus of claim 1 , further comprising display circuitry with a screen to display the OSD menu.
3. The apparatus of claim 1 , wherein the display management module causes an event signal to be sent to the selected video source device to indicate to the selected video source device that it has been selected.
4. The apparatus of claim 1 , wherein a user can select more than one video source device to provide video signals through the interface circuitry to be displayed.
5. The apparatus of claim 1 , wherein the display management module provides tokens and priority to selected video source devices corresponding to the user selection during initialization phase of an OSD graphics connection.
6. The apparatus of claim 5 , wherein the display management module may allow the selected video source devices to provide OSD graphics streams to be displayed and to resolve any conflicts between the OSD graphics streams.
7. The apparatus of claim 1 , wherein the display management module allows only one video source device to be in main control of what is to be displayed, but other video source devices can provide other signals to be displayed.
8. The apparatus of claim 1 , further comprising user selection receiving circuitry to receive commands from a user which cause the display management module to select a different one of the potential video source devices.
9. A method comprising:
identifying potential video source devices on a network outside of an apparatus to potentially provide video signals to the apparatus through an interface circuitry for the apparatus with the network;
generating and displaying an on screen display (OSD) menu including symbols to represent the potential video source devices;
receiving a user selection of at least one of the potential video source devices from the OSD menu;
providing a token to a selected video source device corresponding to the user selection; and
allowing an OSD graphics stream from the selected video source to be displayed responsive to receiving the token back from the selected video source device and validating the token.
10. The method of claim 9 , further comprising transmitting an event signal to the selected video source device to indicate to the selected video source device that it has been selected.
11. The method of claim 9 , wherein a user can select more than one video source device to provide video signals through the interface circuitry to be displayed.
12. The method of claim 9 , further comprising providing tokens and priority to selected video source devices corresponding to the user selection during initialization phase of an OSD graphics connection.
13. The method of claim 12 , further comprising allowing the selected video source devices to provide OSD graphics streams to be displayed and resolving any conflicts between the OSD graphics streams of the selected video source devices.
14. The method of claim 9 , further comprising allowing only one video source device to be in main control of what is to be displayed on the apparatus while one or more other video source devices can provide other signals to be displayed.
15. The method of claim 9 , further comprising receiving a command from a user indicating a selection of a different one of the potential video source devices, and in response arranging for the different one of the potential video source devices to provide other OSD graphics streams through the interface circuitry for display.
