Name

struct dmx_section_filter — Structure that describes a section filter

Synopsis

struct dmx_section_filter {
  u8 filter_value[DMX_MAX_FILTER_SIZE];
  u8 filter_mask[DMX_MAX_FILTER_SIZE];
  u8 filter_mode[DMX_MAX_FILTER_SIZE];
  struct dmx_section_feed * parent;
  void * priv;
};

Members

filter_value[DMX_MAX_FILTER_SIZE]: Contains up to 16 bytes (128 bits) of the TS section header that will be matched by the section filter
filter_mask[DMX_MAX_FILTER_SIZE]: Contains a 16 bytes (128 bits) filter mask with the bits specified by filter_value that will be used on the filter match logic.
filter_mode[DMX_MAX_FILTER_SIZE]: Contains a 16 bytes (128 bits) filter mode.
parent: Pointer to struct dmx_section_feed.
priv: Pointer to private data of the API client.

Description

The filter_mask controls which bits of filter_value are compared with the section headers/payload. On a binary value of 1 in filter_mask, the corresponding bits are compared. The filter only accepts sections that are equal to filter_value in all the tested bit positions.
