Table schema:
CREATE TABLE table_1376890_2 (chroma_format VARCHAR, scalable_modes VARCHAR, intra_dc_precision VARCHAR)

Question: what's the chroma format with scalable modes being snr- or spatial-scalable and intra dc precbeingion being 8, 9, 10
SQL: SELECT chroma_format FROM table_1376890_2 WHERE scalable_modes = "SNR- or spatial-scalable" AND intra_dc_precision = "8, 9, 10"
