Jim, I found this instruction, which confirms the bishop’s authority in his own diocese. It is dated perhaps after the incident with Mother Angelica, but the principle is underlying in other documents, even though she began broadcasting prior to 1996.
From the
USCCB website:
1. Responsibility of the Diocesan Bishop
The bishop of a diocese in which a televised Mass is produced has the responsibility to see that liturgical law is carefully observed, especially regarding the liturgical feasts and seasons, the use of approved liturgical texts and translations of Scripture, proper vesture, and ministers fulfilling their proper roles in the liturgy. Since these telecasts often cross diocesan lines, collegial responsibility should be exercised by the bishops involved (
SC, #22 and Inter Mirifica, #20).
Conclusion
Much more could be said and greater specificity could be given in these guidelines. The guidelines are intentionally limited, however, to allow as much latitude as possible for the local bishop in overseeing the telecasting of the liturgy. These guidelines are provided for bishops to use as the basis for their important work of overseeing the celebration of the liturgy in their dioceses.
