A video still player enhances its picture display capability by buffering a vulnerable channel through which viewer instructions enter the player. Ordinary viewer instructions pass over a relatively direct input channel linking a keyboard and a remote storage device, but one nonetheless defined and safeguarded by a strict editing routine. Enhanced picture processing ordinarily entails difficult and unstructured access to the storage device over this channel, bypassing the "user friendly" editing routine and endangering prepared programs in the remote storage device. By automatically interposing an external compiler into this channel when enhanced processing is initiated, special picture displays can be generated without jeopardizing the integrity of the player. |

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT A video player system including an enhanced picture display capability according to the invention is shown by FIG.
3.
The magazine 2, which is removable from the player as shown by an arrow 20, includes the aforementioned remote memory 5, which contains one or more conventional erasable, programmable memory elements.
When fully inserted into the player, a set of connectors 22 on the memory 5 engages the stationary socket 24.
A circuit path is thereupon provided between the remote memory 5 and the internal processor 7.
In the basic mode of player operation, viewer instructions from the keyboard 6, which are prompted by the edit "screens" generated by the edit program 10, enter the processor 7 via a software switch 26.
The viewer instructions are converted by the format generator 12 into five-byte segments for each picture as shown in connection with FIG.
2A.
If twenty albums are possible, one bit in each segment (20 bits total) will indicate whether a picture belongs to a given album.
Other bits have other meanings based on their position in the segment, i.
e.
, whether to skip a picture, add the date, or provide an elapsed time for automatic viewing.
When editing is completed, the segments form a data base through which the processor will sequentially step, determining from one segment after the other whether a picture belongs to a selected album.
The formatted segments are sent on a line 28 through an OR gate 30 to the remote memory 5.
When an album is to be viewed, the stored data segments are sequentially accessed on a line 32 under control of the internal processor 7.
Each segment is decoded as to its position assignments by the format interpreter 14.
The condition of each bit position in the five-byte string initiates appropriate machine control instructions on a line 34, i.
e.
, for removing a particular disk, for sequencing the head through particular tracks, and for establishing a viewing time.
If the viewing arrangement stored in the remote memory 5 calls for the addition of year and date to the picture, the corresponding text signal is sent on a line 36 through a software switch 38 to the aforementioned text controller 9
