/*
 *
 * Description:
 *  This is the transport stream format header.
 *
 * Settings:
 *  bLength                 - The size of this descriptor in bytes.
 *  bDescriptorType         - CS_INTERFACE.
 *  bDescriptorSubtype      - VS_FORMAT_MPEG2TS descriptor subtype.
 *  bFormatIndex            - A non-zero constant that uniquely identifies the
 *                            format.
 *  bDataOffset             - Offset to TSP packet within MPEG-2 TS transport
 *                            stride, in bytes.
 *  bPacketLength           - Length of TSP packet, in bytes (typically 188).
 *  bStrideLength           - Length of MPEG-2 TS transport stride.
 *  guidStrideFormat        - A Globally Unique Identifier indicating the
 *                            format of the stride data (if any). Set to zeros
 *                            if there is no Stride Data, or if the Stride
 *                            Data is to be ignored by the application.
