Patent ID: 8284311

Claim:
A method comprising: detecting whether to display a dynamic region of a coded stream of digital video data to be displayed over a period of time, by detecting decoded digital data only representing text, the dynamic region including the decoded digital data only representing text data of text of the stream to be displayed in a first portion of a monitor, the dynamic region to be displayed during a selected sub-period of the period of time but not during another different selected sub-period of the period of time, the stream including a different second coded signal including a static region to be displayed in a different second portion of the monitor, wherein detecting decoded digital data only representing text includes: monitoring a decoded graphics stream channel only having digits representing characters of only digital text data, finding a stream of characters of only digital text data included in the channel only having digits representing characters of only digital text data, and based on finding characters of only digital text data, decreasing a vertical size of the static region; then monitoring the decoded graphics stream channel only having digits representing characters of only digital text data, not finding characters of only digital text data included in the channel having decoded text data content, and based on not finding characters of only digital text data, increasing a vertical size of the static region and not combining the dynamic region and the static region into the output to the display device.
